Definitions

  • This invention refers to a new process for the manufacture of sealed boots of the sort commonly known as "gumboots" and more specifically of boots of one height or another with a zip in the leg to make it easier to put the boot on and take it off, with the fundamental aim of ensuring that this type of boot is better sealed.
  • the leg of such boots extends close to the user's knee level to offer suitable protection.
  • the leg of such boots is completely closed to ensure the seal, involving significant difficulties when it comes to putting them on: therefore, more recently, this type of boot has been fitted with a side zip largely affecting the leg and which, when open, makes it much easier to put the boot on and take it off.
  • the zip constitutes a point of loss of seal for the boot since, until now, with existing manufacturing procedures, boots of this type are made in an autoclave, i.e. by the vulcanization of two parts, the sole and the leg, suitably welded together, and the zip then welded to the leg.
  • the welding of the zip to the leg has proved inadequate for ensuring the seal in this area.
  • this type of zipped boot made with existing procedures, ensures greater comfort of use thanks to the introduction of the zip itself, but at the cost of a loss of seal.
  • the process proposed in this invention has been designed to completely resolve the problem outlined above so as to provide a zipped boot which, in addition to the advantages of the zip, also ensures that the boot is virtually completely sealed or hermetic.
  • the process set forth has an initial operative phase in which the zip is simply sewn to the classical fold inside the boot.
  • the zip is then impregnated along its margins or textile sections, where it is secured to said fold, with a thermofusible material which, once thermofused, provides the appropriate seal or hermetic characteristics.
  • the body of the boot is then finally formed, with a single piece, in an injection procedure with the zip-fold unit in the mould, so that the boot material is injected directly on to the margins of the fold and zip thereby perfectly joining them to the leg of the boot, at the same time as the join is sealed by the thermofusion process and subsequent solidification of the substance with which the zip had previously been impregnated.
  • this operative injection phase can be done as described or by including a lining in the mould, like a stocking, which covers the inside surface of the body of the boot.
  • a boot made using the manufacturing process advanced here has a body (1) which is anatomically shaped, with the classic reliefs (2), forming the sole as such and extended upwards with the leg (3) which has a cut (4) for preference on the inside, where a zip (5) is fitted which closes said cut when the boot is in use: in addition, said cut (4) has an internal fold (6) of a size which enables the leg (3) to be deformed as the boot is put on and taken off, i.e. when the zip (5) is open.
  • the process advanced here begins, as already pointed out, by fixing the margins or textile areas (7) of the zip (5) to the fold (6) by sewn seams (8) as shown in detail in figure 2, so that said fold (6), which tends to fold over on itself in the rest position, overlaps on one side over that margin (7) of the zip (5) and inside it, while the opposite side overlaps the margin of the zip on the opposite side, i.e. on its outside, so as to help the fold to crease in the correct position.
  • the zip is impregnated with a thermofusible substance.
  • the assembly made up of the zip (5) and fold (6) is placed in a mould where an single-piece injection operation takes place, to form the body (1) of the boot and its leg (3).
  • thermofusible material with which said zip was impregnated melts, filling all the interstices of the textile material forming the margins (7) of said zip (5) and which, once cooled, creates a virtually hermetic barrier in this area between the leg (3) of the boot and its internal fold (6), and so extending these hermetic characteristics to the boot as a whole, notwithstanding the presence of the zip.
