Machine for lasting heel seat portions of shoes

A machine for lasting heel seat portions of shoes, comprising:

• shoe support means, comprising a heel support, including a last pin which is mounted for limited rocking movement about an axis extending heightwise of the bottom of a shoe supported thereby, and toe support means, including a toe support member which can be urged upwardly against the toe cap portion of a shoe supported on the last pin, thus to set the toe-to-heel orientation of the shoe bottom;
• shoe centralizing means, comprising two shoe-engaging elements, arranged to engage the heel seat of the shoe at opposite sides of the last pin, said elements being movable through equal distances thus to engage and centralize the shoe in relation to a longitudinal center line of the machine by rocking it together with the last pin, about said axis;
• a holddown member which engages the shoe bottom in the heel seat region thereof, while the shoe is held by the shoe centralizing means;
• a heel hand arrangement, between which and the shoe support means relative movement of approach can take place, after widthdrawal of the shoe centralizing means, thus to cause the heel end of the shoe engaged by the holddown member to be clamped by a heel band of said arrangement, in the operation of which arrangement equalized pressure is applied to opposite "legs" of the heel band so that the shoe is clamped substantially in the position in which it is presented to the heel band arrangement;
• and
• heel seat lasting instrumentalities by which lasting marginal portions of the upper are wiped over and pressed against corresponding marginal portions of the insole.
