Abstract: A machine for lasting the toe and side and heel of an upper to an insole mounted to a last includes a toe and ball wiper assembly and a heel and shank wiper assembly in combination with a pincer assembly mechanism for stretching the upper tightly about the last and a toe clamping mechanism for clamping the stretched upper against the last. Following stretching and clamping, the toe wipers are actuated to press the upper margins against the insole bottom against the counter force of an overhead toe hold-down acting against the top of the upper. A brake mechanism fixes the overhead hold-down to maintain the toe wiping plane in a constant position. The heel wiper assembly is elevated within the machine to locate the heel wiper plane at a proper height relative to the insole bottom, the proper height being determined with a sensor mounted for movement with the heel wiper assembly. A heel clamping pad assembly connected to the heel wiper assembly then clamps the heel prior to stretching of the upper.

Abstract: A combined heel end assembling, backpart moulding and heel seat lasting machine comprises a shoe support for supporting a shoe bottom uppermost. For gripping and tensioning the shoe upper on its last prior to the combined operation taking place, two grippers are provided with each of which is associated a reaction lever/presser member, the latter serving to hold the last in position while the grippers tension the upper heightwise. Thereafter, the grippers are moved lengthwise of the shoe to tension the upper about the heel end of the last. The machine also comprises a heel band for backpart moulding and wipers for lasting the heel seat region of the shoe, adhesive applying means being provided for applying adhesive in the heel seat prior to lasting. A plurality of positional adjustments within the shoe support is provided.

Abstract: In a footwear side-lasting machine, the setting movement of pressure members is automated which are operative to upturn and press onto a margin of a footwear blank insole coated with an adhesive a flap of its respective upper, while monitoring the curvature of the footwear blank insole and driving, based on such monitoring, motive members for the setting movement of the pressure members.

Abstract: A machine for lasting the heel of a shoe comprising a shoe last support including an axially displaceable column having a free end. The support is displaceable from a first retracted position to an advanced position and a shoe last is mounted on the free end of the column for limited rocking movement relative thereto to permit realignment of the shoe last. The column may be elevated from a lower position, and when so elevated, strikes the inner edge portion of the heel band wiper plate which has been displaced to a selected position in interference with an edge portion of the shoe last. Such upward movement of the shoe last will be, accordingly, stopped by the interfering edge portion of the heel band wiper plate and the shoe last will be automatically aligned into uniform engagement therewith. The column is locked at the stopped position and a heel band forcefully engages the stopped and aligned shoe last to maintain the shoe last at that position in that alignment.

Abstract: The device according to the invention employs a known clamping assembly to clamp the upper edge to stretch and fold up the edge against the sole. Complementary clamping clips hold the upper edge at the last or to a shoe tree hollow. Also present is a right set and left set of members for upper edge adherence at the last or shoe tree hollow. The aforementioned members are divided into two or more sections independently oscillating about axes approximately parallel to the direction of approaching movement to the last or shoe tree, and independently oscillating about an axis which is approximately horizontal and perpendicular to said direction. The oscillation being controlled by motors that are independent for each individual section. Moreover, each of the right and left sets, is adjustable in height and orientable about an axis parallel to the last or shoe tree approach direction.
