Claims
- 1. Method of lasting shoes comprising the steps of applying adhesive between lasting marginal portions of the shoe upper and corresponding marginal portions of an insole along the side portions and in the heel seat region of the shoe, and lasting said side portions and the heel seat, wherein the side portions are lasted progressively, using lasting rolls starting from the ball region of the shoe bottom and terminating at the heel seat region thereof, adhesive being applied progressively, in advance of the lasting rolls, along the side portions of the shoe, and the heel seat is lasted using wiper plates which overlap the area previously lasted by the lasting rolls, and further wherein, when the lasting of the side portions is completed, the lasting rolls are maintained in contact with the shoe bottom, and thus pressure is applied thereby to the shoe bottom, at the point of termination of the side lasting, while adhesive continues to be applied progressively in the heel seat region, whereafter the applied pressure is removed by retraction of the lasting rolls and the heel seat region is lasted.
- 2. Method according to claim 1 wherein the lasting rolls each comprise a wiping element disposed helically about the circumference of the roll, the in-wiping of the lasting marginal portions of the shoe upper being effected by rotation of the roll about its axis, and further wherein when the side lasting is terminated, rotation of the rolls is also terminated.
- 3. Method according to claim 1 or claim 2 wherein the shoe upper is first pulled over on a last to which the insole is attached and is held tensioned thereon while adhesive is applied to the toe end region of the shoe bottom, and further wherein, as soon as the ball region of the shoe has been lasted by the lasting rolls, the toe end region is lasted using wiper plates which overlap the area previously lasted by the lasting rolls.
