ABSTRACT:
A rigid box toe piece for use in the assembly of a lasted safety shoe is lined in a machine which shapes the liner and attaches it to the inner surface of the steel box. The machine includes a clamp to temporarily hold the positioned box liner with respect to a mold which is shaped to correspond to the toe end of a last. The steel box is placed over the clamped liner and a press then urges the steel box over the liner and onto the mold to press and shape the liner between the box and the mold. The liner is secured to the steel box by adhesive which is applied to the inner surface of the box before the box is placed in the machine so that the pressing step also bonds the liner to the box. The machine includes means for aligning the liner with respect to the mold.
