It will be appreciated from the foregoing brief summary that an apparatus for use in controlling a roll forming machine in a manner such that compensation for springback of a part whose contour is being changed in a complex manner, i.e., in morethan one plane, is provided by the invention. A unique multiplanar sensor senses the curvature of the part as it exits from the machine in two planes. In addition, the "twist" of the part is sensed. All of the sensed information is obtained withoutthe multiplanar sensor distorting the part. Even though the sensor is slightly "downstream" from the Roll forming machine, because the forming process is relatively slow, this information is available rapidly enough to compensate for springback. Thecontrol system used by the invention is relatively uncomplicated in that it merely comprises a comparison arrangement in the form of a divider which compares actual contour signals with desired contour signals and uses the results of the comparison tomodify the signals to be applied to the forming rolls of the roll forming machine, said signals having been previously roughly modified. Modification of the signals is also uncomplicated in that command signals are merely ratio multiplied by suitableelectronic multipliers to obtain corrected command signals.

In accordance with further principles of this invention, the control system includes a memory which stores signal information related to the desired contour of the resultant part. This signal information is applied through a suitable buffer to amanually controllable multiplier which modifies these signals in accordance with the operators experience regarding the amount of springback likely to occur in the part being contour formed. More specifically, a ratio control is manually set by theoperator. This setting controls the setting of the manually controllable multiplier. The setting of the ratio control is a rough approximation of the springback likely to occur in the part being contour formed and is determined by the operator'sexperience with similar parts formed of the same material. In addition, information related to the desired contour is applied to a divider wherein it is compared with contour information derived by the multiplanar sensor. The results of this divisioncomparison are applied to a further or vernier multiplier connected to the output of the rough multiplier to provide a fine or vernier modification of the roughly modified signals. The output of the vernier multiplier is a plurality of corrected commandsignals. These signals are applied to the numerically controlled roll forming machine to control the positioning of the forming rolls.

The present invention finds utility in a roll forming machine of the type which forms an indeterminate length panel having a desired lateral profile from a uniform width supply strip of sheet metal having a pair of parallel straight edges. The roll forming machine drives the supply strip along a predetermined path of travel through a series of spaced roll forming stations, which gradually deform the initially flat strip into the desired lateral profile, illustratively a downwardly concavetrough, to form a rain gutter. As the gutter leaves the machine, it passes through a cutting station, which includes the inventive shear assembly. According to this invention, the shear assembly includes a pair of coplanar blade members separated alonga generally vertical line. The blade members are pivotally connected at their upper ends to a vertically movable actuator block by respective link members which are pivotally connected to the block and to the two blade members. Near the lower ends ofthe blade members are dogleg shaped cam openings which cooperate with respective cam followers secured to the machine. Guide rollers secured to the machine are disposed on opposite sides of the blade members, which have guide surfaces parallel to thevertical movement of the actuator block. roll forming machine The guide surfaces are terminated at their upper ends with beveled surfaces which are angled toward each other. Thus, the movement of the blade members starts off vertically downward until the dogleg bends ofthe cam openings reach the cam followers. At this point, the lower ends of the blade members pivot outwardly about the guide rollers as they continue to move downwardly. When the ends of the cam openings reach the cam followers, the guide surfacebevels reach the guide rollers. The cam followers prevent further downward movement of the blade members, so continued downward movement of the actuator block causes the upper ends of the blade members to pivot outwardly about the cam followers, in theopposite angular direction from the previous outward pivoting. The link members provide enhanced mechanical advantage to movement of the blade members during this final pivoting phase.

An apparatus and method of continuously drawing and annealing wire in a slip mode. The method comprises the steps of directing a wire successively through a plurality of drawing dies of a continuous wire drawing machine, and from the next to the last die of the machine continuously directing the wire to and through apparatus for annealing the wire. From the annealing apparatus the wire is continuously returned to the machine for a final drawing operation. Before the wire is returned to the machine, however, the temperature of the wire is controlled to provide the wire with metallurgical properties suitable for further processing, such as the final drawing operation.
The present invention relates generally to the continuous annealing of drawn wire, and particularly to the process of slip drawing wire in a multi-draw machine and then sending the wire directly and continuously to an annealing apparatus,operating in a slip mode, before the wire is finally drawn and processed. Generally, drawn wire is formed into a package by being wound on a container, such as a reel or spool, or coiled in a hollow manner without a container. One of the more common ways of annealing the package (either partial or full annealing) isto place the package in a furnace. Depending upon the metal and desired characteristics of the wire, the furnace may or may not have a controlled atmosphere, may or may not have the products of combustion in the furnace atmosphere, and the heat providedin the furnace may come from a variety of sources. The package including the wire is heated to a temperature sufficient to anneal the wire. The package remains in the furnace for a period of time sufficient to allow the heat within the furnace topenetrate the entire amount of wire in the package so that all the wire attains the annealing temperature. After this, the package may be discharged from the furnace, to cool naturally, or means may be used to effect a more rapid rate of cooling; or,the package may be cooled in the furnace to a specified temperature and then discharged from the furnace and cooled further. In any case, the package is cooled to a temperature that allows handling of the package.

Straw is presently used to make litter for farm animals such as cows, calves and birds, as for example chickens. Ordinary straw or grain straw serves this purpose except that it at times prevents proper functioning of the stable cleaning systemor the automatic manure disposal. For example ordinary straw making piles whose height increases rapidly particularly when the weather is cold, as in winter. Straw cutting machines have previously been proposed in which cutting was done by a shearingaction. It was discovered that shearing is undesirable because it resulted in the jamming of straw between the movable cutters and the fixed elements of the cutting assembly.

Japanese Laid-open Patent Publication 2005-103623 discloses a wire drawing machine of a non-slip type using an unwinder for unwinding a metal wire to be drawn, a winder for winding the metal wire, and a wire drawing unit for drawing the metal wire. The wire drawing unit is formed of a capstan for drawing (or moving) the metal wire without slip, a dancer roller for applying back tension to the metal wire, and a wire drawing die for reducing the wire diameter. A plurality of such wire drawing units are connected in series between the unwinder and the winder. On the other hand, Japanese Laid-open Patent Publication Hei 10-180342 discloses a wire drawing machine to reduce its size, in which a wire to be drawn is sequentially wound around multiple capstans arranged in series and is transported therethrough, and is also allowed to pass through wire drawing dies placed between adjacent ones of the capstans, so as to draw and reduce the diameter of the wire sequentially through the dies. The capstans are sequentially placed in a zigzag arrangement in the transport direction of the wire so as to form multiple sets of capstans, each set of which consists of three adjacent capstans. Further, a single transmission gear is placed in each set of capstans so that the three capstans in each set are mutually rotated.

However, the conventional wire drawing machine have problems. For example, in the wire drawing machine of Japanese Laid-open Patent Publication 2005-103623, the dancer roller of each wire drawing unit for the application of tension is supported by an end of a dancer arm and driven to pivot about the other end of the dancer arm as a fulcrum. In the wire drawing unit, the wire (to be drawn) having passed the dancer roller is not directly inserted into the wire drawing die, but is required to pass an input guide roller so as to reverse the transport direction of the wire before being inserted into the wire drawing die. Furthermore, the pivot fulcrum of the dancer arm is distant from the wire drawing die in a direction substantially perpendicular to the direction of wire drawing of the wire drawing die, causing the occupying space of the wire drawing unit to be large. As a result, the wire drawing machine using the wire drawing unit or a plurality of such wire drawing units connected to each other becomes large in size. There is a possibility for the wire drawing machine with the multiple connected wire drawing units to be very long in the direction of the connection.

Straw is presently used to make litter for farm animals such as cows, calves and birds, as for example chickens. Ordinary straw or grain straw serves this purpose except that it at times prevents proper functioning of the stable cleaning systemor the automatic manure disposal. For example ordinary straw making piles whose height increases rapidly particularly when the weather is cold, as in winter. Straw cutting machines have previously been proposed in which cutting was done by a shearingaction. It was discovered that shearing is undesirable because it resulted in the jamming of straw between the movable cutters and the fixed elements of the cutting assembly.

An in-line wire drawing machine in which a roller with a one-way clutch allows wire to unwind from a rotatable drum while preventing the wire from slipping reversely on the drum. The roller is supported to float axially relative to the drum so as to track the natural course of the final wrap of wire and is spring-urged against the wire in all of its axial positions.

In a preferred form of the present invention, a wood drying kiln 10 is provided for drying one or more stacks formed as a charge 12 of lumber. A single charge 12 of lumber is made up of multiple layers of boards stacked in a rectangular configuration with stickers 14 separating successive layers. Depending upon the size and configuration of the kiln 10, which may vary according to need, several stacks may be dried simultaneously. Thus a charge 12 may be comprised of numbers of lumber stacks arranged within the kiln 10. The stacks may be placed, one on another and are typically separated by bolsters 16 which are larger in cross section than the stickers 14 to facilitate access to the individual stacks by fork lift tines.

Supported PCD and CBN compacts have garnered wide acceptance for use in cutting and dressing tools, drill bits, and in like applications wherein the hardness and wear properties of such compacts are exploited. In particular, such compacts have been incorporated into dies for drawing feedstocks of such metals as tungsten, copper, iron, molybdenum, and stainless steel into wires. Typically, these wire drawing machine are configured as a generally cylindrical, inner mass of a PCD or CBN compact surrounded by and bonded to an generally annular, outer mass of a metal carbide support. Provided to extend through the compact along the axial centerline thereof is a hole or other aperture into which the metal feedstock is drawn for its elongation into a wire product of a reduced diameter. Wire drawing machines of such general type and methods for manufacturing the same are described in U.S. Pat. Nos. 3,831,428; 4,016,736; 4,129,052; 4,144,739; 4,303,442; 4,370,149; 4,374,900; 4,534,934; 4,828,611; 4,872,333; and 5,033,334.

With respect to the fabrication of the wire drawing machine herein involved, although a variety of methods may be employed, HT/HP sintering processes as are described in U.S. Pat. Nos. 3,831,428 and 4,534,934 may be considered preferred. As with the fabrication of supported compacts in general, the preferred HT/HP processes entail the sweep of a catalytic or binder metal, such as cobalt, through a mass of CBN or PCD particles. For wire die forming processes, the particles are charged within a support of a surrounding metal carbide annulus. At the processing conditions heretofore specified, metal from the support and, optionally, from an axially disposed disc, is made to infiltrate radially and/or axially into the interstices of the crystalline mass. Within the particle mass, the infiltrated metal forms a separate binder phase and, at least with respect to PCD, effects significant intercrystalline bonding. The metal additionally joins the sintered compact to the support to form an integral structure. The wire drawing hole may be formed through the sintered compact as a finishing step by laser drilling or other machining techniques. Alternatively, the hole may be pre-formed by including a wire as axially disposed within the particle mass, which wire is removed after the sintering of the mass by dissolution in a suitable acid or other solvent or by machining techniques.

CVD diamond layers will generally be produced larger in area than that required for a wire drawing machine. Such layers may be cut, for example, by laser cutting, into a variety of useful shapes such as hexagons, squares or discs, the sides of which may be tapered.

An alternative to laser cutting to produce the individual dies or blanks from a CVD diamond layer is the use of photolithography and dry etching such as plasma etching or reactive ion etching of the diamond. By way of example, when oxygen etching is used, after preparing the CVD diamond layer and removing it from the substrate, a layer of a suitable mask material such as titanium, chromium, gold, silicon dioxide or other material which will not degrade in an oxygen plasma environment, is deposited on a side, preferably the smooth side, of the plate by a conventional technique such as vacuum evaporation, plasma assisted chemical vapour deposition, sputtering or the like. This layer is then patterned by known photolithography and wet or dry etching techniques known in the semi-conductor field.

After the desired pattern has been formed on the masking layer, the diamond plate is introduced into a reaction chamber in which an oxidising atmosphere can be created, preferably by the excitation of plasma in an oxygen-containing gas mixture. The diamond is removed in the regions or areas which are not masked.

In place of oxygen, other active gases may be used including halogens such as chlorine or fluorine, introduced in the gas mixtures using techniques known in the semiconductor technology.

Two embodiments of wire drawing machine of the invention are illustrated by FIGS. 1 and 2. Referring first to FIG. 1, there is shown a wire drawing machine comprising a polycrystalline CVD diamond layer 10 mounted in a support 12. The layer 10 has major flat surfaces 14, 16 on each of opposite sides thereof and is mounted in the support 12 such that the periphery 18 is well embedded therein. A hole 20 is formed through the layer 10 from the one major surface 14 to the other major surface 16. In use, wire is drawn through the hole.
