Definitions

  • the invention relates to a method of manufacturing shoes of the type consisting in fitting a rod, optionally provided with a lining, on a rigid form, optionally providing the rod with a hard toe or a metal shell, assembling a mounting sole with said rod during an assembly operation and fixing a outsole on said mounting sole.
  • the first operation of manufacturing a shoe consists in stitching the different pieces in order to constitute the top of the shoe called an upper. Then, this rod is assembled, during the assembly operation, with a sole, generally fine and flexible, called the first assembly.
  • the assembly thus prepared can receive the final sole during the sole operation.
  • the upper can be fitted with a lining and, in the case of safety shoes, with a hard toe or a metal shell.
  • the present invention particularly relates to the mounting operation which is traditionally carried out according to two main methods.
  • the first method uses a rod comprising a mounting return intended to be folded over the first mounting.
  • a rod comprising a mounting return intended to be folded over the first mounting.
  • Such a rod is paved on a rigid form.
  • the first mounting is fixed, by various means, to the rod and the tensioning flap is folded back on this first mounting, to make a complete connection between the rod and the first mounting.
  • the mounting return makes it possible to stretch the material of the upper, generally leather, using its natural elasticity to make it closely match the contours of the rigid shape.
  • the fixing of the first mounting on the rod is done by various known techniques such as nailing, stitching, or gluing.
  • This first method widely used, has the drawbacks of causing a loss of material from the upper by the mounting return and of not allowing a rigorous control of the tension of the leather.
  • a second known method consists in directly assembling a rod without assembly return to the first assembly and, generally, by an edge-to-edge seam. This process has the disadvantage that the edge-to-edge stitching goes up fairly high on the upper and requires an interlocking sole assembly to hide it.
  • interlocking sole assembly is obtained either by injection or vulcanization in a mold which rises above the sting of the rod, or by the use of a cup, stitched or glued sole, and the edges of which rise high enough to hide the sting of the stem.
  • the present invention aims to eliminate the drawbacks of known methods by means of a new mounting method using a rod without mounting feedback.
  • This process is easily automated, facilitates the control of the tension of the leathers and therefore better quality, uses the same shape for mounting and sole assembly operations and therefore allows a reduction of work in progress.
  • this new process allows all types of sole.
  • the method according to the invention is characterized in that, for the mounting operation, the cut rod is placed without mounting return on a rigid form, the first mounting is placed on the sole of said shape rigid, the front of the rod is stamped on said rigid form by means of a stamping die and the said matrix is held tight in the stamping position, the rear of the rod is conformed by means of a form d casing kept tight, the rear part of the rod tightened by the casing form is heated, the sides of the rod are pressed against the rigid form by means of lateral plating blades so that the rod perfectly follows the contours of the form and that the edges of the rod are pressed against the edge of the first assembly, and then the first assembly is assembled at the adjacent edge of the rod, preferably by depositing a bead of glue.
  • the lining and the upper are at least partially glued, so that the operations of stamping the front of the shoe, shaping and heating the rear of the shoe, and lateral plating ensure spreading of the glue and gluing solid upper and lining.
  • the hard toe or, in the case of a safety shoe, the metal shell is put in place.
  • This hard toe or this metal shell is glued and placed between the lining and the upper so that the stamping of the front part of the shoe provides spreading of the glue and a cohesion between upper, hard end or shell and / or lining. .
  • the invention also relates to a device for implementing the above method, as well as the shoes obtained by this method.
  • a rod 1 is cut without mounting return and mounted on a rigid form 2 arranged with the sole 3 directed upwards.
  • the lining is previously attached to the upper 1.
  • the first mounting 4 having exactly the shape and dimensions of the sole 3 of the rigid form 2, is disposed on this sole 3.
  • the hard toe (or the metal shell in the case of safety shoes) is placed between the lining and the upper 1 and glued, these operations can be performed manually or automatically.
  • the assembly consisting of the rod 1 arranged on the form 2 and of the first mounting 4 placed on the sole 3 and this form 2, is introduced into a mounting device shown very schematically in FIG. 4.
  • the mounting device comprises a stamping die 5 for mounting by stamping the front of the shoe.
  • the stamping die 5 drives the front part of the rod 1 and the plate against the anterior end of the rigid form 2, possibly covering the lining and / or the hard end or metal shell.
  • This pressure plating produces a spreading of the adhesive disposed on the lining and / or the hard end or metal shell, ensuring a strong cohesion of this assembly.
  • the matrix encloses the rod, and possibly the hard end or the metal shell, against the rigid form 2.
  • the device further comprises a form of rear casing 7 conforming in volume and in negative to the rear part of the rigid form 2 taking account of the thickness of the rod 1 and possibly of the lining.
  • the form of casing 7 has a horizontal stroke H parallel to the mean plane P of the rigid form 2.
  • the form of casing 7 is associated with a heating system so that, when it is pressed against the rod 1, it ensures, under the combined effect of pressure and heat, a shaping of the rear casing of the shoe.
  • the device further comprises two lateral plating blades 9 and 10.
  • the blade 9 marries in negative and in volume the internal camber of the shoe and the blade 10 marries in negative and in volume the external camber of the shoe.
  • the blades 9 and 10 are moved horizontally along the paths A and B respectively, orthogonal to the plane P, by bringing them together of the rigid form 2.
  • the rod 1 is pressed laterally against the rigid form 2 and the edges of the rod 1 are pressed against the edge of the first assembly 4.
  • the assembly of the rod 2 with the first mounting 4 can take place by any suitable means.
  • a bead of glue 13 (FIGS. 1 and 2) in the angle formed between the edge of the first mounting 4 and the edge of the rod 1.
  • This deposition of glue can advantageously be carried out by an automaton. programmable having memorized the curve of the edge of the first assembly. After setting the glue and after loosening and spacing the stamping die 5, the rear stamping form 7 and the blades 9 and 10, the form 2 is released with a rod 1 assembled to the first assembly 4 and ready to be sown.
  • the sole assembly can be carried out outside the device which has just been described, the shoe mounted being maintained on the rigid form 2.
  • the sole may be of any known type.
  • the bead of adhesive 13 ensures a total seal and prevents the injection of injected material. It provides mechanical and heat resistance comparable to that of a puncture.
  • the first assembly can be partial.
  • the bonding 13 can be discontinuous.
  • the quality of the assembly obtained is higher because the forces exerted on the rod 1 are controlled and harmonized. In particular, frequent breaks or deformations are avoided during mounting of the rod with mounting return.
  • the drawing die 5, the socket form 7 and the blades 9 and 10 can be driven by any means ensuring a precise movement and pressure maintenance against the rigid form 2, for example mechanical, electrical, pneumatic, etc.
