ABSTRACT:
A heel support device for use in a shoe making machine for forming the toe and sides of a shoe upper tensioned over a last seated on a last support include a guide fixed with respect to the machine. A heel support member is mounted for movement guided by the guide by a drive to a supporting position whereat the heel support member bears against and supports a heel portion of the last or heel portion of the upper tensioned therearound. A switch is operatively connected to the drive and is actuated by the heel support member reaching the supporting position to stop operation of the drive upon movement of the heel support member to the supporting position. As a result, the heel support member cannot move the last from a predetermined position.
