摘要:
In a machine for cement lasting side portions and the heel seat of shoes, the side portions are lasted by lasting rolls and the heel seat by wiper plates. For applying adhesive, each lasting roll has an associated nozzle which applies adhesive progressively in advance of its associated lasting roll. Furthermore, when the lasting rolls reach the point of termination of side lasting, they remain in pressing engagement with the shoe bottom, but their rotation is terminated, and in this condition the nozzles continue to apply adhesive in the heel seat region. This may be achieved by merely discharging adhesive from the stationary nozzles and allowing it to run into the heel seat, or alternatively the nozzles may track bodily into the heel seat. Thereafter, the lasting rolls and nozzles are retracted and heel seat wiping can take place. The invention may also be incorporated in a machine in which the whole of the shoe bottom is lasted.
