Abstract: An apparatus and method for cutting sheet material is provided which includes a numerically controlled cutting machine which cuts a spread of sheet material positioned on a supporting surface of penetrable material. Each individual pattern piece desired to be cut is converted to a numerical program form for controlling the cutting machine, and is stored for ready retrieval, for example in a computer memory. Indexing marks are provided on the spread to be cut, the cutter is positioned relative to such marks, the desired program pattern is selected and the cutter is controlled by the selected program to cut the desired pattern. The process is repeated until all desired pattern pieces are cut, thereby providing great flexibility in pattern selection and placement on a spread or plurality of spreads of materials.

Abstract: Apparatus for supporting a stack or layup of air-impervious sheet material to be cut or otherwise worked upon includes a horizontal base on which the stack is positioned. The stack is covered by an air-impervious cover sheet, and by as associated vacuum means, air is withdrawn from between the top of the stack and the cover sheet to create a sub-atmospheric pressure under the cover sheet whereby atmospheric pressure on the top of the cover sheet will hold the stack in a firm condition while it is worked upon by a cutting tool or the like. The means for withdrawing air from between the cover sheet and the top of the stack includes a porous or air conducting layer of material, such as corrugated cardboard, which may be part of the cover sheet or a separate sheet in itself. If the material of this stack includes layers of porous material alternating with layers of air-impervious material, the latter porous layers themselves serve as air-conducting layers for withdrawing air from below the cover sheet and from between the layers of air-impervious material of the stack. Preferably, to provide the vacuum means, the horizontal base for supporting the stack is air-pervious and located over a vacuum chamber with the vacuum from the chamber passing through the horizontal base and past the longitudinal edges of the stack, through a block or layer of air conducting material, to the space between the cover sheet and the top of the stack.

Abstract: Apparatus for cutting layups of sheet material and including an elongated table for supporting a layup, a main carriage supported for movement longitudinally of the table and a cutting tool supported on the main carriage for movement therewith and relative thereto in cutting engagement with the layup. The main carriage and the cutting tool move in response to positioning signals received from a numerically controlled or computerized controller. A pair of power driven hold-down rolls positioned at opposite sides of the cutting tool extend transversely of the table and move with the main carriage and in rolling engagement with the upper surface of the layup. At least one of the rolls is driven so that its tangential velocity at its point of contact with the layup is substantially equal to the lineal speed of the main carriage relative to the table but in the opposite direction. Thus, the one roll has a substantially zero velocity relative to the supporting table at its point of contact with the layup and exerts only a downwardly directed force upon the layup. Both rolls may be driven in the aforesaid manner, or, if desired, one of the rolls may be driven at a slightly different speed than the other roll to impart spreading action to the layup in the vicinity of the cutting tool.

Abstract: A sheet material cutter of the type using a reciprocating cantilevered blade includes a relatively thin reciprocating blade and a guide or sheath that surrounds the blade rearwardly of its forward cutting edge to provide extra rigidity for the blade reducing lateral and rearward deflection by the forces imposed thereon during a cutting operation. In addition to a generally vertical forward cutting edge for cutting sheet material as the blade is moved in the plane thereof, the blade also includes, at its lower end, a generally downwardly facing cutting edge permitting the blade to cut in a plunging fashion by moving it and the guide generally perpendicularly into the material being cut. The blade and guide are so constructed as to allow them to cut, during plunging movement, a slit in the sheet material equal to approximately the combined front to rear dimension of the blade and guide so that as the blade and guide are plunged into the material being cut the slit made thereby will readily accommodate the blade and the guide without seriously displacing the material or causing other problems.

Abstract: Apparatus for cutting and notching layups of sheet material includes a layup support means and a main carriage slidably mounted for movement in a first coordinate direction relative to such support means. First and second cutting heads are movably supported on the carriage for movement therewith in said first coordinate direction and for movement with respect thereto in at least one other coordinate direction. The carriage as well as the first and second cutting heads move in response to positioning signals supplied by a computerized controller. A first movable blade or cutting tool is driven by the first cutting head and is adapted to engage the layup to form a cut thereon as the cutting head is moved in a plane parallel to the layup. A second blade or cutting tool is driven from the second cutting head and is adapted to move in a plunging fashion relative to the layup to form a notch or cut therein.

Abstract: A method for working on sheet material or other objects uses a vacuum holddown device having a material-supporting surface including a plurality of vacuum openings passing therethrough. A vacuum chamber associated with the supporting surface applies a vacuum through the vacuum openings to the sheet material or other object received thereon. A sheet or panel of substantially airimpervious sheet material, such as a sheet of thin polyethylene, is spread over the exposed surface of the work, and cooperates with the vacuum to draw it toward the supporting surface and into a more compact condition. The air-impervious panel used with the vacuum may be an expendable sheet of such material spread entirely over the surface of the work prior to the performance of work thereon and/or may be one or two continuous belts of such material located in front of and/or behind the work tool. The vacuum and air-impervious panel may also be used to hold a layup of sheet material to be cut in a compact condition for a long period of time between the laying up process and the cutting process to prevent the various layers of the layup from shifting, flowing or otherwise moving relative to one another so as to depart from their relative positions as initially laid up.

Abstract: In an automatically controlled cutting machine for cutting thick layups of sheet material, apparatus is provided to dispense a liquid fluid onto the tool for cooling, lubricating or other ancillary functions. The apparatus includes a presser foot which rides on top of the sheet material during a cutting operation and the presser foot permits liquid to flow to the reciprocating blade whenever the blade is cutting through the sheet material. A liquid absorbing material in the presser foot insures that the cutting portion of the blade receives the liquid.

Abstract: A hollow needle member is used to apply a substance to a sheet of material for marking same or for applying a fluid material along a cut edge of the sheet material. The hollow needle member is mounted for reciprocation along its axis thereof. A controller receives coded input information and converts the input information into two-dimensional directional command pulses and a needle action command pulse. The needle member is moved in response to the two-dimensional directional command pulses over a sheet of material to which the substance is to be applied so that the needle member is disposed in a preselected location over the sheet of material. The needle member is reciprocated in response to the needle action command pulse so that the needle member is contiguous to the sheet of material. Marking material or fluid material which prevents edge fray or bonds edges of several sheets of material is ejected through the hollow needle member to the sheet material. Various specific embodiments of the device include specific needle member moving means and response mechanisms. One specific embodiment is directed to a combination of a hollow needle member mounted for reciprocation along with a cutting mechanism both of which are automatically controlled through the use of a controller.
