Davis, Madison, Ill. Appiication May 15, 1945, Serial No. 593,950 4 Claims. (01. 1V2‘—63) 2 This invention relates to machines designed for skiving counter stiffeners of shoes, the pri which are disposed directly opposite to each mary object of the invention being to provide ?llers having recesses of various sizes, and de signs, the ?llers being constructed so that they may be readily removed and replaced, to the end viding shoulders l5 adjacent to the ends thereof. The matrix ?llers embody semicircular mern~ bers 16 which are constructed of suitable mate that the machine may be readily converted for other, the flanges having cut-out portions l4. pro“ rial, preferably plastic material, the members H5 being curved so that they will accurately fit the constructing counter stiffener blanks of various curvature of the matrix roll I I. As clearly shown sizes and designs, without the necessity of re by Fig. 4 of the drawings, one end of each matrix moving the matrix and replacing it with a matrix 10 ?ller section It is formed with cut-out portions of a different size or design; thereby reducing adjacent to one of its ends, providing an exten the time'period for converting the machine, to a minimum. . Another object of the invention is to provide sion H, the extensions" of the sections of the matrix ?ller, being positioned within the cut-out portions Id of the matrix roll.
