It has long been realized that the exposed edge
of the lining of a shoe upper is unduly con
spicuous around the exposed edge of the upper,
as at the'foot opening. Usually the edge of the
‘ lining, especially when‘it is made of leather, has‘
a raw edge, no attempt being made to ?nish this
edge before the shoe upper is assembled. Fre
quently, too, it is of a color contrasting with
that of the shoe upper. This renders this edge

stitched but not yet lasted. It will comprise the
upper material 26, theexposed edge of which is
located in the machine by an ‘overhanging edge

edge ‘or one which has been ?nished with French
binding or the like. Within the upper and at

edge of which is usually a raw edge. It will be
noted that the gage 28 is adjustably held in po

the side of the bearing member 44.
Treatment of the edge of the lining to thin it
and render it less conspicuous is e?fected by
means of a thin hammering-disk 10, shown in
Figs. 3 and 5 as slab-sided and preferably of
hexagonal contour with slightly rounded corners.
This disk is mounted on the end of a shaft 12
journaled in a bearing block 14 which has up
