Inflation of both of the cushions 37 and 50 proceeds until an inflated operative condition is reached.

  • solidification is also a result of the presence in the gluing material of particles of water, which, during heating, are converted into vapour and diffuse throughout the gluing material transforming it into an unmeltable and tough solid body.

  • the subsequent advance of the belts causes connection of the openings of the cushions 37 and 50 to the discharge, consequent deflation of the cushions 37 and 50 themselves, and gradual removal of the bell-shaped body 46, which enables the item of footwear to be picked up and taken away to the station 10'.
  • the plant 1 described enables a uniform and stable connection of the sole to be obtained irrespective of the geometrical conditions or the conditions of memory of the sole or of the upper, in so far as melting of the gluing material in conditions of pressure favours the diffusion of the liquefied gluing material between the sole and the upper and filling of all the gaps pr/esent between the sole and the upper, whilst maintenance of the conditions of forcing until complete resolidification of the gluing material determines a high stability of join and shape.
  • cushion bodies to force the upper and the sole against one another makes it possible to exert not only an energetic forcing action but also a uniform forcing over the entire item of footwear.
  • the inflatable cushions 37 free the upper 4 and the corresponding supporting member 33 from any external rigid constraints. Said uniformity of forcing enables a reduction, once again with respect to the known solutions, of the amount of the forcing action and hence of the stresses transferred to the upper, which, consequently, must no longer be oversized with evident reduction in costs and use of materials.
  • each of the cushions 50 housed in the bell-shaped bodies 46 comprises a seat for at least partial housing and positioning of the sole 3 and a plurality of holes which can be connected to a vacuum source for withholding the sole 3 so that it engages the aforesaid seat, thus providing an automatic positioning of the sole 3 on the corresponding upper 4 without any need to envisage the station 8.
  • the mode and/or the conveyors for displacement the uppers and the soles could be different, as likewise the inflatable-cushion bodies could be different in number and as regards shape.
  • the cushions 37 could not uncouple the supporting members 33 from the completely respective pins 32 but only slide them off in such a way that the pins 32 engage the corresponding blind hole with radial play.
  • the sources of heat 52 set in each of the inflatable cushion bodies 50 may be replaced by a single common source of heat set in the intermediate area of pressing 9 and associated to the bell-shaped body 46, which is located in the area 9 and in which the gluing material must be heated.
