A heel-lasting machine for footwear manufacture

摘要

A heel-lasting machine for footwear manufacture comprises support means (1) on which to position a last (A) over which an upper (C) is stretched and with which an insole (B) covered with glue is associated, a plurality of tensioning clamps for engaging and pulling the edge of the upper (C), means for clamping the last (A) to the support means (1), and means for bending and pressing the edge of the upper (C) onto the insole (B) in the region of the rear portion (4) and of the sides (5) of the insole (B). The machine advantageously comprises two nozzles (7) for supplying hot air towards the portions of the insole (B) which are covered with glue and which are to come into contact with the folded and pressed edge of the upper (C). The nozzles are movable in order to follow the edge of the insole (B) along the rear portion and the sides thereof and are moved by actuating means which bring about their movement in a manner such that the air jet emerging from the nozzles (7) is directed along the edges of the insole (B). <IMAGE>
