Abstract: A cutting knife assembly has a projecting cutting knife (12) detacheably connected to a baseboard (10). The cutting knife circumscribes a knife cavity (18) on the baseboard (10). An elongate cross member (20) extends across the knife cavity (18), is affixed to the cutting knife (12) and is mounted to the baseboard (10) by a removable fastener.

Abstract: 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.

Abstract: A die assembly including an upper male mold (42), an annular cutting blade (46), and pressure plate (80) carried by the upper plate (40) of an upper die set (18); and a female mold (24) secured to the lower plate (22) of a lower die set (16). The blade (46) is positioned in surrounding relation to the male mold (42); the pressure plate (80) is positioned in surrounding relation to the blade (46); and an annular seal (48) encircles male mold (42) within blade (46). The upper die set (18) clamps a sheet of component material (90) positioned over the female mold (24) and is moved downwardly into the cavity (24a) by selective slippage controlled by selective adjustment of the pressure plate (80). Stop means (30) are provided to delimit the downward movement of the male mold (42) whereafter a lost motion connection allows the die (18) to continue downwardly and the cutter blade (46) to trim the sheet edge with resin being injected through the female mold to permeate sheet material (90).
