Definitions

  • the invention relates to an improved flocked material suitable for preparing continuous flocked extrudates for use as window wiping seals or the like for automotive and other vehicle uses.
  • Automobiles and other mobile units typically include windows that can be raised and lowered. These windows are generally held within frames having a seal designed to wipe the window as they are moved from a closed, exposed position to one internal of a door body or the like.
  • the wiping edge is typically dressed with a flocking (velvet-like material) to enable the wiping edge to ride smoothly over the surface of the window and wipe it as it is drawn against the wiping edge.
  • One established method for manufacturing the combined seal/wiper involves extruding a base member comprised of a polymeric material, often also including a metal structural section, and applying a flock in the form of a plastic substrate having flocking adhered to it. Sheets of this flocked substrate are typically cut into narrow strips, often called flocked tapes, and rolled onto spools of a size convenient for shipping and handling. Typical spools can hold up to a thousand yards or more, e.g., 2500 yards in some cases. These spools contain splices each of which causes a length of the extruded part to be scrapped.
  • the tape When attaching a tape of this type to an extruded base member, the tape is preferably fed into contact with the extruded base member within the extruder die used to form the base member or suitably after the extruder die. Because an extruder of the type used to produce a combined seal/wiper operates continuously to shape the polymeric material into the desired cross section, it would be desirable for the tape to be continuous also. Unfortunately, this has not been possible as a practical matter due to the finite length and materials of manufacture. The presence of splices will not only cause unsightly and dysfunctional parts — unacceptable to the automobile manufacturers and consumers alike — it can also affect the operation of an extruder, which is intended to operate on a continuous basis.
  • Figure 1 is a schematic, cross-sectional view of a molded combined seal/wiper having two flocked wiping surfaces according to the invention
  • Figure 2 is a schematic side elevation of a typical extrusion process for forming a combined seal/wiper of the type shown in Figure 1;
  • Figures 3-5 are foreshortened top plan views illustrating the steps involved in forming the splice of the invention
  • Figures 6-9 are schematic cross sectional views of several embodiments of splicing tapes employed according to the invention.
  • the invention provides an improved process for preparing a molded combined seal/wiper having at least one flocked wiping surface.
  • the invention provides a process for preparing a flocked tape having a base film side and a flocked side with a usable splice comprising: cutting the ends of two sections of flocked tape along a diagonal; abutting the two cut ends of flocked tape along a common diagonal cut line; contacting base film side of the flocked tape at the cut line with a heat-sealable, reinforced tape; and applying heat and pressure to the heat-sealable, reinforced tape sufficient in time and degree to form a secure splice.
  • the invention provides a spliced flocked tape prepared according to the process above.
  • the invention provides a process for preparing a continuous flocked extrudate for use as window wiping seals, comprising: preparing a spliced flocked tape according to the process above; continuously extruding a resin; and contacting the resin while hot with the spliced flocked tape.
  • locked extrudate is meant to include contoured members made of one or more plastic materials, some with embedded metal reinforcements, designed to be fixed to an opening in a door or other vehicle part, which can be used to guide and/or support a window or other moveable member.
  • locked tape is meant to include tapes such as those offered by Dorrie International of Norwalk, CT under the trade designations 80 Black FlockTM made of black polyester fiber flock bonded to a black PVC (polyvinyl chloride) film and 50 Black FlockTM made of black polyester fiber flock bonded to a black polyolefin film.
  • PVC backed material is useful for adhering in an extruder to PVC and its elastomers, such as those sold under the Alcryn® and Sunprene® trademarks.

  • Figure 7 shows outer layers of PVC adhered by layers 124 and 124' to a reinforcing layer of a suitable polyester such as 0.5 mil polyethylene terephthalate.
  • Figure 8 shows outer layers of polyolefin 126 and 126' adhered by layers 124 and 124' to a reinforcing layer of a suitable polyester such as 0.5 mil polyethylene terephthalate.
  • Figure 9 is similar, but shows a layer of cross-linked polyolefin 130 in place of the polyester and does not employ an adhesive.
  • These two illustrations are suitable for use with base films of polyolefin, especially suitable for use with an extruded resin that is a member selected from the group consisting of TPO, TPE, EPDM and TPV.

Abstract

L'invention concerne un procédé de préparation d'un ruban floqué (12, 12') comprenant un côté film de base et un côté floqué avec un raccord pouvant être utilisé. Les extrémités des deux sections du ruban floqué sont coupées le long d'une diagonale. Les deux extrémités coupées du ruban floqué viennent en contact contre une ligne de coupe en diagonale commune. Le côté film de base du ruban floqué est alors mis en contact au niveau de la ligne de coupe avec un ruban thermoscellable renforcé. De la chaleur et de la pression sont alors appliquées pour former le thermoscellage. Dans un autre aspect, l'invention concerne un procédé de préparation d'un élément extrudé floqué continu destiné à être utilisé en tant que dispositif de nettoyage de vitre, et consistant à préparer un ruban floqué à raccord selon le procédé mentionné ci-dessus, à extruder de manière continue une résine, et à mettre en contact la résine pendant qu'elle est chaude avec le ruban floqué à raccord.
