Definitions

  • the present invention relates to an apparatus for the manufacture of shoes with an inner leg, particularly skiboots.
  • the apparatus is adapted for the performance of a method for the manufacture of such boots, according to which an inner leg mounted on a last is provided with an outer shoe by insertion during the manufacture in a hollow mold of a liquid and paste-like, respectively, synthetic materialand rubber mass, respectively.
  • the bottom part can be arranged for a variation of its hollowvolume of the mold displaceably and/or exchangeably.
  • the last carrying the inner leg is suitably pressable to the hollow part by clamping means as, for instance, a pulling cord, a pulling rod and the like, also magnetically.
  • FIGURE 1 is a section along the lines A-B of FIG. 2;
  • FIG. 2 is a section along the lines C-D of FIG. 1.
  • the apparatus comprises a last 1 on which an inner leg 2 of leather is mounted. While it is suitable to combine the leg leather with the inner sole by means of a seam, also any other known expedient can be applied.
  • a hollow member 6 is mounted on the leg or to say more exactly, on the inner leg disposed thereon, whereby the last is pressed to the hollow member 6 by means of any tensioning means 8.
  • a sealing point and a sealing edge 9 respectively, results up to which the leg leather is uncovered and from which further portions of the leather are covered and are received in the hollow 7.
  • the mentioned parts are formed of two half bowls 3 and 4 and the body portion 5.
  • the hollow portion 6 and the non-covered part of the inner leg 2 are shown in elevation.
  • the bottom portion 5 has a filling opening through which liquid and paste-like, respectively, synthetic material or rubber mass can be fed into the mold.
  • the surfaces of the molds coming in contact with the penetrating synthetic material and the hollow part 6 are treated with a separating agent, in order to avoid an adhesion of the 5 synthetic material.
  • a separating agent in order to avoid an adhesion of the 5 synthetic material.
  • the apparatus in accordance with the present inven tion permits also the application of the method in the simplest manner with different masses from the outer leg and for the sole, respectively.
  • the outer leg can be formed in a first process step and then after corresponding adjustment of the bottom portion 5 and the exchange of the inner sole, respectively.
  • these parts can be simultaneously secured on the shoe or in the shoe during its manufacture. Even if the arrangement of the filling opening 10 in the bottom portion 5 appears particularly advantageous, one or a plurality of such openings can be of course provided at another point of the hollow mold.
  • An apparatus for the manufacture of shoes with an inner leg, particularly ski-boots, comprising a multi-part hollow mold
