<p>A machine for preparing flexible sheet material to be assembled and stiffened. The invention is more especially concerned with providing mechanism for cyclically assembling and stiffening selected portions of footwear, for instance a precoated toe portion of a vamp and a lining. The machine includes in novel combination a particle dispensing means, ply-combining mechanism, and pressure conforming means. A dispensing device distributes granular reinforcing material to the coating of adhesive on an activated formable sheet material, particles of the reinforced material being retained in a thickness pattern conducive to sequential pressure-forming of the assembly, and then recirculates unused granules.</p> |
