The method of lasting footwear with liquid latex comprising depositing the latex in a wet, liquid, low-viscosity, nonadhesive form on the surface of the feed roll, of a pair of cooperating feed rolls of a progressive-type lasting machine, which normally has contact with the inner side of the lasting margin of the upper material at a place apart from the lasting margin, while the deposited latex is traveling from the place of deposit on the surface of the feed roll having contact with the inner side of the lasting margin to the place of contact with the lasting margin, spreading it uniformly thereon and rendering it partially coagulated and adhesive, transferring the partially coagulated adhesive latex to the lasting margin at the place of contact and, as the latex-coated surface of the lasting margin is released, pressing it against the latex-receptive surface of the insole, and apparatus for carrying out the method.

Lasting machine with latex adhesive delivery

The method of wet lasting the lasting margin of a shoe upper to the marginal edge of the bottom structure which comprises, progressively lasting the lasting margin of an upper to the margin of a bottom structure which has along its margin at least, a dry receptive adhesive coating and while so lasting the margin applying a liquid coating of latex in a controlled amount to the inner side of the lasting margin just before it is laid down.
