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“
