ABSTRACT:
An apparatus for shaping the counters of shoe uppers is of the type which includes, on higher portions of the same frame or framework, two heating stations for heating portions of the upper, reactivating glue for assembly of the shoe uppers. In lower portions of the apparatus, two shaping stations for shaping the counters, which are made of a preform, comprise a last and shaper able to engage with one another to clamp the shoe upper tightly. The apparatus is provided with instrumentalities allowing each shaping station to operate in three stages; namely, (a) holding of the shoe piece on the last and fitting it to the height of the shoe upper, (b) positioning of the piece by holding of the preform shaper on the shoe upper at slight pressure, and then (c) properly shaping by clamping of the shoe upper between the shaper and last under a rather high pressure of 5 to 6 kg/cm.sup.2.
