ABSTRACT:
In a lasting machine shoes are supported with one end aligned with end lasting instrumentalities arranged to operate at that one end, and with the other end thus offset to the longitudinal center line of the instrumentalities (and thus of the machine). The support for the other end of the shoe includes a sensing arrangement mounted to slide transversely of the shoe. The sliding movement serves to distinguish left and right shoes and also to sense the amount of the offset. In addition the length of the shoe is measured from its initial lengthwise clamping. The various measurements are made electronically, e.g. using linear potentiometers. The signals are supplied to a control device (microprocessor) by which control signals are supplied to motors, e.g. stepping motors, for controlling tools, e.g. adhesive applying nozzles, to guide the latter along the sides of the shoe.
