Definitions

  • the present invention relates to the field of apparatus for manufacturing shoes and more specifically relates to a particular adaptation, for the production of very long buttresses, of double-station machines, that is to say working in pairs, intended to reactivate the iron-on parts of the shoe elements to be assembled and then give the final shape to the rear parts of the shoes.
  • the shaping is carried out using a shaping device by introducing the rear of the shoe onto a form (or punch) metallic then by pressurizing this shape in contact with the curved element, or actual shaper.
  • the machine works by pair of shoes and generally comprises, on the same frame, in the upper part, two stations for hot reactivation of the adhesive for assembling the constituent elements of the shoe and, in the lower part, the double station conformator / punch intended for curving and stabilizing it at low temperature.
  • Such machines are well suited for the manufacture of common shoes in which the rear parts do not have a long curve, such as for example men's shoes.
  • the aforementioned devices can only work on the rear part of the buttress and do not provide by the curve which extends thereon. .
  • the new machine conventionally comprises a double station, at its upper part, for reactivating the glue of the preassembled shoe elements, and, at its lower part, a second double shaping station / punch intended for curving proper.
  • the metal punch used for each of the two stations is curved in great length at the conformation of the buttress and, moreover, the conformator of the second station is produced in such a way that its lower part, which we will call according to use "square shape", has a hardness significantly greater than that of the upper part.
  • the buttress curving machine is of the type and of automatic operation known per se and it will essentially be noted that it is provided: on the upper part of the frame 1 with a group of two conformers (2 , 3) with their metal punches (4, 5) and, on the actual working table 6, of a double station of two conformers (7, 8) with their respective punches (9,10).
  • the upper double station is intended for the hot reactivation of buttresses made of hot-melt and fusible material, with conformers made for example in two layers, one of which is made of silicone resin loaded with 30/40% by weight of metal powder (aluminum ) and a surface layer of pure silicone.
  • the station (7, 8) on the work table is used for curving proper, with stabilization of the curve pneumatic or hydraulic pressure refrigerated temperature.
  • the punches used are very elongated and have the exact shape of the buttress. For example, they have an average length of 150 mm for the heels of ladies' heeled shoes.
  • the shaping and stabilizing conformers (7, 8) are produced in a single piece of plastic material (for example, silicone resin or the like) but they have the particularity of having two distinctly different hardness indices, for example of the '' from 50 to 70 shores for the upper part A and included in the range of 85 to 110 shores for the base of the skirt or edge of form B.
  • the buttresses cut flat in sheets of thermo-adhesive synthetic material are introduced directly into the upper of the shoe, before being put into the reactivation position, without carrying out any prior operation for pre-cleaning these long buttresses.
  • the second known phase of tightening the buttresses in the shaping assemblies (7, 8) punch (9, 10) at refrigerated temperature excellent results are obtained and markedly improved compared to the curving devices known up to now because the very hard edge (B) of the conformers ensures perfect rigidity between the rear elements of the shoe while the more flexible upper part (A) does not there is no wrinkling during the pressurization of the elements of the shoe.
