Abstract: A method and apparatus for supporting sheet material such as cloth during operations thereon such as cutting wherein a pattern is placed on a supporting surface provided with a plurality of pins extending through apertures in the surface, the pins are lowered below the surface for removal of the pattern whereupon sheet material is placed on the surface, typically a plurality of plies being layed up in a stack, and simultaneously the pins are moved through the sheet material to maintain alignment and matching of the plies in the stack. The pattern then is placed on the sheet material in a position determined by the location of the pins, and the material is shaped such as by cutting. A plurality of separate pin holding and supporting devices of narrow width are spaced lengthwise along the apparatus and independently movable lengthwise toward and away from each other. Pins of adjacent rows can be closely spaced together thereby achieving a grid pattern wherein the pins are relatively closely spaced.

Abstract: A leading edge of a web is fed to an upstream cutting station and is gripped at the cutting station with an upstream clamp which is then advanced downstream away from the cutting station to a middle station and is arrested in the middle station where the leading edge of the web is gripped with a downstream clamp and released from the upstream clamp. The leading edge held by the downstream clamp is then moved downstream to a holding station and the opened upstream clamp is moved along the web to a position slightly upstream of the upstream cutting station. The web is then gripped immediately downstream of the upstream cutting station with an upstream clamping conveyor and immediately upstream of the downstream holding station with a downstream clamping conveyor, and is gripped immediately upstream of the upstream cutting station with the upstream clamp.

Abstract: The present invention relates to a method and an apparatus for producing mat packets from panels of an adhesive material which adhesive material is covered with release layers. The panel of adhesive material is advanced sequentially through a feed device, a clamping device, a release layer removing device and a cutting device. The leading edge of the panel, with the release layers removed, extends freely beyond the clamping device toward the cutting device. The panel is advanced in increments corresponding to the length of the mat strip to be produced, and, when the panels are clamped by the clamping device, the panels with release layers removed are cut into mat strips, which are deposited on a transporting device in stacks of several on top of one another to form a mat packet.

Abstract: When assembling a magnetic disk cartridge, a liner material strip having a plurality of circular openings arranged in a row at predetermined intervals is fed intermittently in the direction of the row of the openings and cut to predetermined lengths in synchronization with the intermittent feed to predetermined lengths, whereby liners each having a circular opening is formed. A locator pin which is smaller in diameter than the opening and has an arcuate locating side wall portion the radius of curvature of which is substantially equal to that of the opening is inserted into the frontmost one of the openings with the locating side wall portion opposed to the front edge of the frontmost one of the openings when the liner material strip is stopped.

Abstract: A guillotine type cutting machine for stacks of paper sheets has a table which supports the stock to be cut and a knife which can sever the stock in a vertical cutting plane. A feeding unit is provided to advance the stock along the table across the cutting plane, and a hold-down device is provided at the cutting plane to engage and press upon the stock opposite the descending knife while the stock is being severed. This hold-down device further serves to bear upon the stock during expulsion of air from the stock preparatory to the first cutting step. The air expelling unit has a roller which is lowered onto the stock adjacent the hold-down device and is then moved along the stock toward the feeding unit to expel air from pockets between the sheets. A cover is placed between the roller of the air expelling unit and the stock so that the roller need not directly engage the topmost sheet of the stock.

Abstract: Method and apparatus for automatically providing notching indicia on the edge of a garment subassembly to provide a dimensional reference to be utilized in subsequent fabrication of the goods. A conveyor transports the garment subassembly to a notching station at which the pre-assembled parts are secured in accurate registration to the path of a notching device that is movable on a carriage toward and away from the notching station. The notching device includes a vertically extending notching blade having a recessed cutting edge which, when positioned at the notching station, overlies an edge of the garment part subassembly. On displacing the blade downward, the notch indicia is cut into the garment piece after which the notching unit is withdrawn to a home position while the notched part is transported by the conveyor to a subsequent fabrication step. In a preferred embodiment two notching devices supported in a common path on opposite sides of the notching station are utilized.

Abstract: Programmable apparatus for cutting woven fabric wound on a supply roll includes a fabric spreader which pays-off fabric from the supply roll and onto a cutting table as the spreader moves relative to the table. A vibrating member carried by the fabric spreader and over which the payed-off fabric is constrained to pass imparts vibration to a portion of the fabric which extends across the entire width of the fabric to relieve residual stresses within the fabric as it is spread onto the table surface. The spread fabric is immediately cut by a rotary cutting wheel which moves in cutting engagement with the fabric in response to command signals received from a programmable controller.

Abstract: An automatically controlled machine for cutting limp sheet material includes a vacuum bed defining a surface on which the sheet material is spread and held during cutting. A reciprocating cutting blade penetrates through the sheet material and the support surface of the vacuum bed as the blade is translated parallel to the support surface along lines of cut. A plurality of air-impermeable panels extend through the bed in spaced relationship to sectionalize the vacuum bed and permit the vacuum to be generated only in those portions of the bed where the cutting blade is operating. To prevent interference with the penetrating cutting blade, the panels are individually withdrawn from the bed when the cutting blade approaches.

Abstract: A method for dividing a semiconductor wafer into pellets includes attaching the wafer to a vinyl membrane with a coupling material which adheres more tenaciously to the membrane than to the pellets and sawing completely through the wafer and at least partially through the coupling material to separate the wafer into discrete pellets. In accordance with a preferred method, the membrane is at least slightly cut by the saw to insure complete division of the wafer. The pellets are readily removed from the coated membrane without any residues remaining thereon from the coupling material. A resinous vinyl coupling material is preferred.

Abstract: The method hereof, conducted at the factory or site of printing of the wall covering, advantageously uses the same work or printing station reference that accurately positions the imprinted pattern on the wall covering substrate for the positioning of cutting means effective to sever said substrate free of the opposite unprinted selvage areas. Thus, although the substrate, which typically is a 100-foot strip, may be inadvertently slightly misaligned from a perfectly straight orientation, the cutting means nevertheless effectively moves along that path which accurately slits free the selvages of the "misaligned" substrate because it is guided by said imprinting reference during said movement.

Abstract: One or more glass or other brittle fiber ends are prepared by first embedding the fiber in epoxy or other plastic and then slicing the plastic and the fiber a first time to produce an oblique end face and a second time to produce an end face exhibiting intersecting planes. The slicing is continued with successive advancements of the slicing of approximately one thousandth of an inch to produce a squared end. The technique is applicable to fiber end preparation of single fibers and plural fibers as in optical fiber tapes and cables.

Abstract: A method and apparatus for the transverse cutting of elongated material such as superposed web plies (for example, a convolutely wound log) wherein the material is uniformly advanced along an axial path and a cutting disc blade is moved through an orbit in planetary fashion which intersects the path and is skewed relative thereto while the disc blade is rotating in planes perpendicular to the path.

Abstract: A process for cutting a multi-filament tow into fibers of ultra-short length and narrow size distribution is provided. Initially, a multi-filament tow is passed through a bath of liquid impregnating material at elevated temperature. The impregnated tow is then passed through a die which is sized to control the quantity of material impregnating the tow and to compact the filaments of the tow into a closely packed bundle. The resulting tow is then cooled to solidify the impregnating material and to convert the tow to a rigid form. The rigid tow is then cut, yielding wafer-thin disks. The impregnating material is then stripped from the wafer-thin disks with a solvent followed by removal of the solvent, thereby yielding fibers of ultra-short length and narrow size distribution.
