Definitions

  • the invention relates to a method for manufacturing a shoe insole which comprises an insole blank and a model piece attached thereto.
  • An essential part of the footwear sole construction is the insole which gives the desired form to the inner sole of the shoe.
  • insole it is customary to use an uppermost insole blank made of cellulose-based special material, and a special model piece attached underneath the insole blank.
  • the model piece has a spring part between it and the lower surface of the insole blank, the spring part providing the insole with sufficient rigidity and the right form.
  • a hard paper board manufactured by using a special method has been used as the model piece, this board tapering off towards the front end in order to form a regularly curved lower surface together with the insole blank.
  • Document US-A-3 835 558 discloses a method where an insole is assembled from a long layer and one or more short layers in one step.
  • the object of the invention is to eliminate the above mentioned drawbacks and to present a method for manufacturing an insole and model piece which lack the disadvantages caused by the prior art.
  • the method according to the invention is mainly characterized by the fact that the model piece is a multi-layer construction having a plastic film providing the rigidity and shape of the model piece and textile layers formed of fibres and attached on both sides of the plastic layer and the model piece is attached as said multi-layer material to the lower surface of the insole blank.
  • the plastic film in the middle of the model piece provides the construction of the insole with rigidity and tightness. Due to the textile surfaces the model piece can be properly glued and the insole has good stretching properties both by nailing and gluing tools.
  • the mechanical fixing means such as heel nails and rivets and barbs of the spring part, remain well fixed in the model piece.
  • the mechanical fixing means such as heel nails and rivets and barbs of the spring part.
  • the textile layers are advantageously of non-woven fabric forming a surface which is easy to handle.
  • the fibre material of the textile layers is advantageously of synthetic plastic material which does not absorb humidity as much as cellulose fibre.
  • Fig. 1 illustrates the insole of the invention in a longitudinal vertical section
  • Fig. 2 illustrates the same directly from the back, i.e., seen from the heel direction
  • Fig. 3 illustrates the insole from the top.
  • the insole comprises an insole blank 2, to the lower surface of which a model piece 1 is attached.
  • the model piece has three layers, an intermediate layer formed of plastic sheet 1b, and textile layers 1a and 1c on both sides thereof, the former of which forms the lower surface of the insole in the area where the model piece 1 is attached to the insole blank 2.
  • the upper layer 1c forms mainly a surface which is to be attached to the lower surface of the insole blank, and on the front side thereof the upper layer of the model piece is formed of the material of the plastic sheet 1b and on the front side thereof of the material of the lower textile layer 1a because the model piece 1 is made thinner at its front end from the side of the upper layer.
  • the insole blank can be of any previously known flexible material, such as material available with trade names "TEXON” and “BONTEX”, which is cut to a shape required for the shoe sole.
  • Textile layers 1a and 1c formed of fibres can be textile constructions of several types, the fibres of which textile structures have a good gluing ability e.g. with heat-activated glues when different phases in manufacturing of insole and shoe are considered.
  • the most advantageous textile material is a non-woven fabric, i.e., non-woven, which is relatively easy to manufacture of desired fibre materials, also of mixtures of different staple fibres, and which is easy to work in different manufacturing phases.
  • the construction fibre of the textile layers is advantageously a synthetic plastic fibre, e.g. polyester fibre.
  • the plastic sheet 1b can be of any plastic having suitable strength values, advantageously some thermoplastic plastic which can be shaped by heat, and which, when cold, regains such a rigidity that it gives the rear portion the required form when attached to the blank 2. In this situation, the insole bends only at the front part to be situated under the ball of the foot.
  • the model pieces can be cut in desired shapes of a ready-made sheet-like material manufactured by gluing non-woven fabric layers on both sides of a large plastic sheet, such manufacturing techniques of multi-layer materials being previously known.
  • a ready-made sheet-like material manufactured by gluing non-woven fabric layers on both sides of a large plastic sheet, such manufacturing techniques of multi-layer materials being previously known.
  • an insole is manufactured by combining a special model piece with normal insole materials in use.
  • the model piece has alternatively a material thickness of:
  • the thickness of the intermediate plastic sheet can be selected according to the rigidity values characteristic to each material.
  • the thickness is most commonly between 0.5 and 2 mm.
  • Model piece blanks are detached from the sheet in desired shapes by die cutting on both sides.
  • the blanks are thinned to suitable shapes at their front edges and, if necessary, also at their sides. If needed, in each piece a groove is cut for the spring part.
  • the spring part is attached to the piece by riveting or pressing by using attaching barbs (at both ends).
  • the model piece, as well as the insole blank, is glued by PU-glue.
  • the glue: surface of the model piece is dried by heat and ventilation.
  • the dry model piece is softened by means of heat and simultaneously the PU-glue in the piece is activated.
  • the activated model piece activated in this way is attached to its place in the insole blank and pressed together.
  • the united insole is immediately shaped by an insole-shaping press by employing a shaping mould of the right shape, the right pressing time and pressure.
  • the shaped insole which is sufficiently cooled is edge bevelled at the area of the model piece to the required extent by means of an edge bevelling tool. If necessary, the insole is still neatened whereafter it is ready to be packed.
  • a separate metal spring is not necessarily required, particularly in flat heel shoes, because the operation of the spring can then be replaced with the plastic sheet 1b having a large area.
  • the insole can be used in connection with footwear manufacturing in a normal manner.
  • the upper is stretched tight at its edge to the lower surface of the insole and attached by nailing (nails penetrating the insole and clinched against the upper surface of the last), or with a gluing method.
