Roughly rounds outsole and welt to conform to shape of last. Cuts small
channel along edge for stitches.]
The next operation is that of trimming the sole and welt so that they
will protrude a uniform distance from the edge of the shoe. This work
is performed on the Goodyear Universal Rough Rounding Machine, which
gauges the distance exactly from the edge of the last. It is often
desired to have the edge extended further on the outside of the shoe
than it does on the inside and also that the width of the edge should
be considerably reduced in the shank of the shoe. This is taken care of
with great accuracy by the use of this machine. The operator is able
to change the width at will. By the use of this remarkable machine the
operator is also enabled to make the sole of the shoe conform exactly
to all others of similar size and design.
