In a pulling over and lasting machine in addition to a toe pincer there are provided two sets of side pincers, each set being mounted on a support pivotal about an axis extending heightwise of the shoe bottom and passing through or adjacent the toe pincer. Each pincer is adjustably mounted on its support but in addition each set is movable bodily, through its support, about its axis. The supports are movable equidistantly in opposite directions, i.e. towards and away from one another, into a selected one of a plurality of pre-set positions thus to accommodate to shoes of different widths. For moving the supports a plurality of cylinders are arranged in tandem and operable according to the selected pre-set position of the support.

Pulling over and toe lasting machine

A heel attaching machine is provided with an abutment mounted on a pneumatic piston and cylinder unit. After a shoe upper and heel have been positioned on the nailing stand of the machine, the abutment is moved upwards into engagement with the shank region of the insole of the shoe. The abutment then serves to prevent the upper from tipping about the edge of the nailing stand during insertion of the heel attaching nails.

Heel attaching machine

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.
