Title: MACHINE FOR ROUGHING THE MARGIN OF AN UPPER OF A SHOE ASSEMBLY
Abstract:
A roughing machine having a support (68, 72) for supporting bottom-up a shoe assembly (82) formed of a last (84) having an insole (88) located on its bottom and an upper (86) mounted thereon with the margin (90) of the upper (86) secured to the bottom of the insole (88) and roughing tool (74) located above the shoe assembly (82) and yieldably urged downwardly against the shoe assembly (82) so as to rough the upper margin (90) during movement of the support (68, 72) to move the upper margin past the roughing tool (74). The shoe assembly bottom has its heel seat portion (92), its shank portion (94) and its forepart portion (96) lying in different planes. The support (68, 72) is so constructed as to be rockable in such a manner that the heel seat portion, the shank portion, and the forepart portion of the upper margin (90) all lie in horizontal planes during their movement past the roughing tool (74).
