Apparatus for lasting a toe, side and heel portion of a shoe.

摘要

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 the 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).
