Definitions

  • the .front portion l0 of the insole for the gluing process which consists of a'particularlyv thin leather layer and a thin leather strip extending along the edge, is united by an interposed elastic intermediate layer which preferably extends in knownmanner over an elastic filling mass for the shoe already contained in the insole.
  • the invention and the novelty in its fundamental idea consist in that an ordinary leather insole is split at its front end, and between these two leather portions which, owing to their slight thickness, are necessarily flexible, an elastic intermediate layer such as rubber is inserted so that the iiexibility of the two leather parts is retained and the insole nevertheless offers sufflcient durability and resistance during the working.
  • a leather sole about 2 to 3 mms. in thickness, such as is generally employed for insoles, is stiff and brittle. If this leather sole is split into two layers of uniform thickness, each of these two'layers is exible and elastic but does not 'offer suliicient resistance to allow of work- Wing to form an insole. If for example a thin rubber layer is inserted between these two layers, the exibility of the entire arrangement remains, because the two leather layers, in spite of being intimately connected by the rubber layer, can always shift relatively according to the elasticity of the rubberemployed.
  • 'I'he elasticintermediate layer preferably extends in known manner over thelling which consists of a porous sponge rubber-like mass.
  • the filling mass is directly connected to the intermediate layer, whereas it isonly in loose contact with the leather layer.
  • Fig. 1 shows an insole in bottom plan view.
  • Fig. 2 is a section on line 1I'-]I of Fig. 1.
  • the insole serving for use for the gluing or Mackay process consists of a leather layer a which is either continuous or, as is known, composed of two parts connected along the broken line C-D.
  • the middle portion of the leather layer a is loosely connected to a porous rubber sponge-like filling mass b, which is stuck to the elastic intermediate' layer c and extends up to the edge of the sole.
  • a leather strip d extendingA along the edge is iixed and either made in one piece or divided on the broken line E-F.
  • the insole according to the invention may be produced inthe following manner: A leather insole about 3'mms. in thickness is stamped in the usual' shape, trimmed,A scoured and split 75 at the front end up to the shank, so that a layer of about 1 mm. in'thickness remains on the sole, whereas a second layer about 1 mm. in thickness drops olf.
  • the edge strip about 12 to 15 mms. in Width, is stamped out of the 8,0 upper split.
  • the filling mass and a solid rubber sole, about 0.5 mms. in thickness, are then stamped out.
  • the parts are itted together in the following manner:-
  • the elastic cover c which is directly connected to the porous filling b, is stuck on the front portion of the insole along the edge of the leather layer a. by means of its edge strip'.
  • the leather strip d is then stuck on to the solid rubber layer c along its edge.
  • the leather strip d is provided in order to enable the insole to-be employed for the gluing process andV also in order to impart a certain strength to the insole.
  • the advantages of such a method for producing insoles and for lling foot wear for the gluing and Mackay processes are the following-f Y
  • the exibility is obtained by splitting the front portion a and introducing the elastic intermediate layer c.
  • the lling b which is only in loose contact with the leather layer a, does not impair the elasticityv of the insole.
  • the shoe or the filling need not be subjected to a. long drying process, so that the shoe can be manufactured in a much shorter time than hitherto.
  • An insole comprising in combination a piece of leather cut to the shape of the insole and thinned at its front portion, a. thin leather strip extending around the thinned portion of said leather piece, a porous rubber sponge-like filling mass in the space surrounded by said strip, and an elastic intermediate layerbetween said stripand said leather piece extending over and covering said lling mass.
