摘要： Cutting of a material (710, 712), such as a textile or film, can damage the material. A tool (100) is provided that utilizes vacuum pressure near a knife edge (104) to increase a result of the cut. The vacuum pressure passes through a base portion (302) of the tool that has a recessed portion (312) effective to distribute vacuum pressure to one or more apertures (214) extending around an insert (206) of a core portion (202). The one or more apertures (214) align with a void between the knife edge (104) and the insert (206) allowing for the void to transmit the vacuum pressure through the tool (100) to the knife edge (104). A machine horn (702) may then cut the material (710) at the knife edge (104) and couple the material (710) with another material (712).

摘要： A method of cutting stacked layers of compressible material utilizing a steel rule cutting die. An open cell foam member (18, 20) is placed in the area between spaced portions of the cutting die (16) to define a flat upper surface substantially flush with the sharpened upper edge (16a) of the cutting die. The stacked layers (22) of compressible material are placed on top of the foam member (18, 20) and on top of the sharpened upper edge (16a) of the die and the upper platen (10) of the associated press is lowered to precompress the stacked compressible layers (22) prior to the cutting operation by the die. The foam member (18, 20) is an open cell member and has a compressibility such that it maintains a flat upper face ( 18a, 20a) flush with the upper cutting edge of the die during the precompression of the layers (22) and thereafter moves downwardly in a smooth translatory manner to allow the layers (22) to be moved downwardly through the cutting die. The invention methodology avoids distorsion of the fabric pile during the cutting and allows the cutting of even very high stacks of compressible fabric without substantial variation in the shape or length of the cut pieces and without any substantial beveling of the edges of the cut pieces.
