Definitions

  • the invention relates to a powder application device and to a process for the production of thermoplastically deformable semifinished products for use as stiffening elements.
  • thermoplastic stiffening materials for shaping and shape retention in the footwear, garment and bag making industries has long been known.
  • stiffening material e.g. punched in the desired shape during shoe production and thinned (sharpened) at the edges to avoid signing the transition to the unreinforced "shoe upper material”.
  • the blanks are usually ironed by means of hot punches on the shoe upper and are thermoplastically deformable under heat and after cooling for the shape retention of the shoe responsible.
  • thermoplastic sheet material can be made both by impregnation of a textile fabric with an aqueous plastic dispersion, which is usually provided after drying still one or both sides with a hot melt adhesive, by extrusion and also be superficially provided with hot melt adhesive, as well as by the powder sintering method, at the melting plastic powder or powder mixtures containing melted and sintered with or without textile carrier.
  • a disadvantage of the web process is in particular the increased material consumption by the waste during punching, which must be disposed of or recycled. In addition, it is not possible to produce products with sharpened edges in a single operation.
  • stiffening materials are known, which are made by applying, melting and sintering and then smoothing powdered mixtures of plastic, fillers with a defined particle size distribution in the range of 50 to 500 ⁇ and optionally other excipients on textile carrier or auxiliary carrier ,
  • a powder mixture with increased filler content can be made available which correspondingly has improved rigidity and increased viscosity has, so that a penetration of the plastic melt is prevented on the textile carrier or auxiliary carrier.
  • DE 33 47 237 A1 describes the production of three-dimensional stiffening parts, which by applying meltable plastic powder by means of a screen printing template in the form of the desired stiffening on a receiving tape or subcarrier and subsequent melting and direct subsequent transfer to a shoe upper by means of a special pressing device.
  • a particular disadvantage is the complicated guidance of the powder application device, which moves in a squeegee movement over the screen printing stencil and compacts the introduced powder at the edges, which is not desirable.
  • the hole template is mounted directly above a receiving tape (subcarrier) and transversely to the direction of travel, as well as lowered on the same.
  • thermoplastic powder mixture doctor blade moves in the lowered position on the recording tape hole pattern alternately from a left "parking position" to a right “parking position”: This movement can also be as pulled or pushed describe.
  • the hole cutouts of the hole template are each filled with the thermoplastic powder mixture.
  • the hole template is lifted together with the doctor box in parking position until the powder applied with the recording tape in the next stop position, the heating zone is driven, and then lowered again for the next application process.
  • the method has the disadvantage that the doctor box wipes or rakelt over the cutouts of the hole template, ie the thermoplastic powder mixture is filled from a moving column of powder in the hole cutouts and at the edges of the hole deducted extracts.
  • This has the disadvantage that the amount of powder applied is not exactly controllable, so that it comes to a one-sided uneven powder application, and in particular by the blade movement (shutter movement) the edges of the blanks formed in the hole cutouts of the stencil are compressed from the thermoplastic powder mixture.
  • the powder applicator is expensive because it has to be guided in a complex movement, in the horizontal as well as in the vertical direction.
  • thermoplastically deformable semifinished products wherein the device should be technically easy to implement, in particular performs a simple, unidimensional translation movement, and then improved thermoplastically deformable semi-finished products are available which can be easily adapted to the changing market requirements in terms of shape, physical properties, in particular stiffness, and chemical properties.

  • the powder applicator B comprising the powder container B and the perforated template L rigidly connected thereto, is designed such that it performs a simple vertical translational movement to thereby lowerable to the subcarrier to which the powder mixture is applied, or to a slight distance thereto, usually of a maximum of 5 mm.
  • the hole template L is below the powder container B and spaced therefrom, that is arranged at a distance from the powder container B.
  • the powder container B There are basically no restrictions on the geometry and capacity of the powder container B; it is essential that it has at its lower end an opening which is sufficiently large to trickle enough material of the meltable plastic powder-containing powder mixture into the hole cutouts of the hole template L, so that they are filled in an economically appropriate time.

  • the hole template L is thus a negative template comprising hole cutouts which corresponds to the geometric shape of the semi-finished products to be produced, and which are interconnected by webs.
  • the hole template L must be so stable (stiff) that it can withstand the pressure of the powder column without deforming.

It should also be noted that the hole cutouts still need to be sufficiently far apart from each other, so that the blanks, which are formed by the plastic powder is introduced into the individual cutouts, not connect to each other, and in particular not in the subsequent processing under Supply of heat merge together.
