Method and apparatus for automatic manufacturing of shoes

摘要

In the automatic production of shoes, a single layer sole is injected directly onto a shoe upper, on a last. The moulds (21 forming the sole travel in series to the injection machine. They are conveyed around a circuit. They arrive at a preparation station (2), and are completely closed, to produce a sole moulding cavity. Passing through a buffer station (3), the assembled moulds reach the injection station (6), where they are secured and adjusted. Injection follows, then passage to a further buffer station (7) and cooling. Following a set interval, the moulds are opened at yet another station, removing the finished shoe. Passing through a cleaning station, the open, empty mould goes round again, or is removed. Also claimed is a plant to carry out the above process.
