Definitions

  • the invention relates to a method of assembling of a safety shoe in which a metal plate is secured between a lining and the upper.
  • a pocket is formed by means of the upper lining, the component parts of which are coated with an adhesive.
  • the pocket so formed is then placed over a member having the shape of the toe end of the shoe, and is covered with a metal plate which may be provided with a suitable filler.
  • the front portion of the upper which may be pre-shaped, is then turned inwardly.
  • a flexible insole member may be duck or any other suitable material, is attached by the method known as slip-lasting.
  • the upper thus assembled is placed on a mold for attachment thereto of a sole of elastomeric or plastomeric material.
  • FIG. 1 is a bottom plan view of a shoe upper and a lining before the forming of a pocket in accordance with the invention
  • FIG. 2 is a similar view of a shoe upper and lining with a pocket formed therein;
  • FIG. 3 is a bottom plan view of an upper assembled in accordance with the invention, with a toe plate, and ready for attachment of an insole.
  • the upper 2 comprises a lining 1, the front portion of which is not cemented to the upper.
  • the lining is cut so as to form two parts 3 and 3a, which have previously been coated with a heat-sensitive cement. These two parts are joined by a line of stitches 4 to form a pocket 5, which is then placed on a heated metal form to activate the cement.
  • a steel plate 6 is then fitted over the pocket 5, together with a filler 7 which adheres to the lining 1 (FIG. 3).
  • the filler 7 has a shape corresponding to the contour of the front part of the shoe.
  • the front part of the upper 2 is then turned inwardly to produce the shape for the front part of the upper as shown in FIG. 3.
  • a flexible insole (not shown) is then sewn along the margin of the upper '2 and of the quarter 8.
  • the upper thus assembled may then be placed upon a mold to have a sole of elastomeric or plastomeric material attached thereto by direct molding.
  • a method of assembling the upper of a safety shoe for attachment thereto of a sole by direct molding comprising securing a lining to a shoe upper in a region outside a front part of the upper, forming a pocket in said lining at said front part by cutting the lining in a central region thereof to form two adjacent parts and stitching said parts together along a junction line, securing a safety toe plate to the lining at said pocket, and turning the front part of the upper inwardly whereby an assembly is formed to 'which a flexible insole member can be attached and a sole directly molded.
  • a method as claimed in claim 3 comprising securing to said pocket a member having a shape corresponding to the contour of the front part of the shoe, whereby the pocket is sandwiched between the member and said upper.
