The machine comprises a shoe support (20) for e.g. a heel seat and side lasting machine has a last pin (24) on which a shoe may be positioned, bottom up, having a shoe heel end positioning mechanism (86) including a heel height gauge device (110) for locating the heel end of the shoe to lengthwise and heightwise datums, and a toe support (30), including an abutment (54) for setting a toe height datum (54a), each of said datums being adjustable according to the style of shoe being operated upon. The machine also includes a heel band mechanism (150), the arrangement being that the shoe heel end positioning mechanism (86) is moved to an out-of-the-way position after the shoe has been positioned, thus allowing the heel band mechanism (150) to move into shoe engagement. The shoe is held by auxiliary clamp means (184) during this changeover.

Machine for use in the manufacture of shoes

The machine comprises a shoe support (20), two side lasting assemblies (230) and a heel seat wiper mechansim (170), the shoe support comprising a last pin (24), a toe support (30) and a heel band mechanism (150). The heel band mechanism is mounted for rotation about an axis (158) whereby a shoe clamped thereby, after a lasting operation has been completed, can be removed from the operating locality of the machine onto a shoe-receiving platform (330) on to which the heel band mechanism then releases the shoe. The shoe support 30) also includes a shoe heel end positioning mechanism (86) by which a next shoe to be operated upon can be located at the operating locality of the machine during the removal of the shoe which has been lasted.

Machine for lasting side and heel seat portions of shoes

The machine comprises a shoe support (10) and two side lasting instrumentalities (20), each of which comprises a fluid bag assembly (40) which, in a tilted position (determined by an abutment 44), is moved into engagement with a shoe, whereafter, by continued inward movement, the bag assemblies (40) are caused to pivot (or roll) upwardly and over the shoe bottom edge, thus to urge the shoe upper around the feather edge of the last and against the insole. The bag assemblies are inflatable, a higher air pressure being applied, so as to apply bedding pressure to the lasting margin, after the assemblies (40) have moved fully inwardly.

Machine for lasting side portions of shoes

Side lasting machine has a last support and two side lasting assemblies each comprising a plurality of lasting fingers, a plurality of clamp pads arranged beneath the fingers, one associated with each pair of fingers, and, depending from each finger and interposed between the pads and the upper, a plurality of lasting bands. Each band extends over the width of not less than two fingers; preferably in the region of the two most heelwardly disposed pairs, a single band is provided. Each pad is mounted for independent pivotal movement about a vertical axis, to enable it to conform more readily to the last contour. The pads hold the bands against the upper under a pressure sufficient to allow slipping therebetween, the band thus applying an updrafting force to the upper as the fingers move inwardly.
