Definitions

  • This invention lies within the scope of the technological sector of the shoe manufacturing industry, being particularly involved in a manufacturing process for the kind of footwear that may either be used for sports purposes or in combination with informal dress.
  • this kind of footwear first entails a vamp being made, with a mid-sole stitched to it, then the outer surface of the mid-sole being glued to the vamp surface of a sole made of a material such as rubber.
  • a stiff inner insole made either of plastic material (synthetic resin) or of pressed cardboard or even wood which is usually called the heel-sole is initially inserted inside the sole in such a way as to remain close to the upper surface of the afore-mentioned sole.
  • this insole or heel-sole extending from the area of the footwear corresponding to the heel to just beyond the plantar arch is to make the footwear sufficiently rigid.
  • the edge of the sole is then stitched to the vamp to reinforce the join between the component parts of the footwear.
  • the glue does, in fact, have to be applied first to the upper surface of the sole, and then to the outer surface of the mid-sole.
  • both the sole and the mid-sole with its attached vamp will have to be placed in a stove for a previously determined length of time.
  • vamp is positioned above the sole, and the mid-sole is subjected to a previously determined amount of pressure so that the glue will stick efficiently.
  • the aim of this invention is to propose a manufacturing process for sports shoes, which by virtue of its being a technical procedure that is both easy and cheap to manufacture, consists of a series of operations that are less complicated than those of the previously described process, thus offering considerable improvements in the production of said articles in terms of both the time and costs involved in their manufacture.
  • a further aim of this invention is to propose a procedure whereby each of the operations being carried out is reversible.
  • the above-mentioned aim can be achieved by a manufacturing process for footwear, of the kind consisting of a vamp, a mid-sole attached to said vamp once its lower part is closed, and a sole which will initially be attached to said vamp by being joined to said mid-sole, and later on by its edge being stitched to said vamp;
  • this process is characterised by the fact that it entails the following operations: the manufacture of said vamp, the manufacture of said mid-­sole and said sole respectively, complete with parts that can be matched together thus joining or separating said sole to the mid-sole, simply by means of pressure; the attaching by stitching of said mid-sole to said vamp; the joining by simple pressure of said sole to said mid-sole with said vamp attached to it; and the stitching of the edge of said sole to said vamp.
  • number 1 indicates the footwear that we are proposing to manufacture by this process.
  • Figure 1 in particular, shows a vamp 2, a mid-sole 3, and the sole 4 of the footwear 1.
  • the vamp 2 has been manufactured according to known procedures from leather or some other material that is usually used in the manufacture of footwears.
  • the mid-sole 3 is obtained by placing a number of seats 6 on one of its facings, in such a way that they are uniformly distributed over the surface of the latter.
  • the sole 4 is made of synthetic resin, and is obtained by pouring this material in the liquid state into a suitably shaped die containing a stiffened inner insole 7, or heel-sole, made from a material such as plastic.
  • the seats and the raised layers may obviously take on whatever shape proves best on each separate occasion.
  • the strip 5 then becomes a single integral part of the sole 4 during manufacture of the latter, and the facing with the raised layers faces outwards.
  • This may, for example, be inserted inside the die used to make the sole, prior to pouring in the material in its liquid state, and positioned immediately above the insole, 7.
  • the next stage of the procedure entails attaching the sole 4 to the mid-sole 3, and consequently also to the vamp 2, this being done by virtue of the joining together of the two facings of the strip 5 and the mid-­sole 3 respectively, featuring the raised layers 8 and the seats 6, by inserting the latter inside said seats 6 through the simple exertion of pressure.
  • the mid-sole could be made from one of the two component parts of a velcro strip fastening (this is not shown since it is known).
  • velcro is a material consisting of two sides, which are correspondingly paired by simple pressure, and which is used as a means of rapidly joining together or separating strips of cloth or similar things.
  • the mid-sole 13 is made by cutting a corresponding surface from one of the two component parts of the velcro, and it is then stitched to the vamp 12, with the lower part of the vamp closed and with the facing to be matched to the remaining part of the velcro facing outwards.
  • the strip 15, on the other hand, which has the same surface and shape as the mid-sole 13, is made from the other component side of the velcro strip and becomes a single integral part of the sole 14 during its manufacture.
  • the strip 15 may, for example, be inserted inside the die used to make the sole, prior to pouring in the material in its liquid state, and positioned immediately above the plastic insole.
  • the next stage of the procedure entails the attaching of the sole 14 to the mid-sole 13 and consequently to the vamp 12, attached to it, this being done by joining together the two sides of velcro 5 forming the mid-sole 13 and the strip 15, respectively, by simply exerting pressure.
  • a further manufacturing process entails the manufacture of the mid-sole and the strip with the use of polyurethane.
  • the polyurethane is attached to the sole and the two parts of polyurethane are joined together by heating the afore-mentioned parts.
