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 apparatus comprises a pulling over and toe lasting machine and a side and heel seat lasting machine. The pulling over and toe lasting machine comprises two linear potentiometers (102, 104) for monitoring the movement of the heel rest (26) both lengthwise and heightwise of a shoe, a left/right sensor (PrS2) and a proximity switch (PrS1) which senses when the wiper plates (20) reach a predetermined position in their inwiping movement and causes output value information from the potentiometers (102, 104) and left/right sensor (PrS2) to be 'read'. The side and heel seat lasting machine comprises two side lasting assemblies (36) tiltable in a direction lengthwise of the shoe, to accommodate to the spring of the last, and two adhesive-applying nozzles (40) arranged to track along opposite portions of the shoe. A further linear potentiometer (146) monitors the nozzle movement, and stepping motors (66) are provided for effecting tilting movement of the assemblies (36). The side and seat lasting machine also comprises computer control means (FIGS. 7 to 11) which received the output value information from the linear potentiometers (102, 104) and left/right sensor (PrS2) of the pulling and lasting machine and, in accordance therewith, causes the angle of tilt of the side lasting assemblies (36) and also the distance through which the nozzles (40) are driven to be set. The apparatus may also include an automatic unloading device (122).
