Abstract

663,492. Cutting rubber thread. STEVENS, A. H. (Andrews-Alderfer Processing Co., Inc.). July 5, 1949, No. 17707/49. Class 70 [Also in Group VIII] A machine for subdividing a sheet of rubber or the like into a multiplicity of threads comprises two sets of rotatable disc-knives arranged in interleaved relation with relatively small arcs of adjacent pairs of knives in overlapping, shearing relation, the knives being spaced a distance greater than the thickness of a knife to provide a throat narrower then the thickness of the sheet in which a portion of the rubber will be compressed during the cutting operation. As shown in Fig. 4, rubber R is sheared at the points of contact of opposing sets or disc cutters 15 and during cutting the individual threads are deformed so as to extend into the space between the non-cutting edges of opposing discs, thus producing an axial pressure in the direction of the arrows q, which pressure forces the cutting edges of the opposing discs against one another. The shafts on which the two sets of discs are mounted are relatively inclined at a small angle as shown in Fig. 5 so as to produce a more pronounced shearing action.
