Definitions

  • the present invention relates generally to methods and apparatus for creasing planar material and more particularly to a method and apparatus utilizing heated filaments to provide crease lines in planar material such as fiberglass-type sheets.
  • Planar materials which are semi-rigid in construction can many times be folded along a predetermined line by providing a crease in the material along the designated fold line.
  • Such fold lines are desirable in ceiling panels of the type described in copending provisional patent application Serial No. 60/148,834, filed August 13, 1999 entitled “Ceiling System with Replaceable Panels,” priority to which is claimed herein.
  • the disclosure in the aforenoted application is also hereby incorporated by reference.
  • Ceilings of building structures have taken numerous forms. They may be left unfinished so that rafters or beams of the building structure itself are exposed or the rafter and beams may be covered as with drywall, wood strips, plaster or other similar finishes. Walls of building structures ma be similarly finished.
  • drop ceiling Another popular ceiling system is commonly referred to as a drop ceiling where a plurality of support bars are suspended from the unfinished ceiling so as to form a matrix having a plurality of side-by-side openings defined between the support bars.
  • the openings are filled with panels which are typically rigid acoustical panels, with the panels being supported along their peripheral edge by the support bars.
  • the present invention pertains to a new and improved system for cauterizing planar sheets of material to form creases therein along predetermined lines.
  • planar sheets such as sheets made of glass fibers embedded in resins
  • a pair of confronting and rotatable drums are mounted in slightly spaced relationship so that the planar material to be cauterized and creased can be passed therebetween.
  • At least one of the drums includes at least one conductive filament or wire so that the wire can be heated to a temperature exceeding that which will cauterize the resin in a glass fiber panel.
  • the drums are rotated as the planar material is advanced therebetween and as the drums are rotated, the heated filament or filaments thereon engage the planar material at preselected locations to cauterize the material and thereby provide a crease in the material consistent with the size and configuration of the heated filament.
  • FIG. 1 is an isometric view of an apparatus for creasing planar sheets of material in accordance with the present invention.
  • Fig. 2 is vertical section of a portion of the apparatus shown in Fig. 1, illustrating the confronting drums and the sheet of planar material passing there between.
  • Fig. 3 is a fragmentary isometric view of a panel formed with a sheet that has been creased and folded with the apparatus shown in Fig. 1.
  • Fig. 4 is a side elevation of a planar sheet of material having been creased with the apparatus of Fig 1.
  • Fig. 5 is an end view of a folded sheet formed from a planar sheet of material that has been creased with the apparatus of the present invention and further showing a folding device for folding the creased material along the crease lines.
  • Fig. 6 is a fragmentary section taking along line 6-6 of Fig. 2.
  • Fig. 7 is a fragmentary section taking along line 7-7 of Fig. 6.
  • the apparatus includes a pair of confronting cylindrical drums 12 and 14, a supply roll 16 of planar sheet material 18 that passes around an idler roller 20 before being fed between the confronting drums and into a folding apparatus 22 for folding the cut and creased planar sheets of material 18 into products, for example, of the configuration shown in Fig. 5.
  • the apparatus 10 can be modified to form various types of creases 24 in planar sheet material in accordance with desired fold lines 26 (Fig. 5) for forming products 27 of various configurations.
  • the product illustrated in Fig.5 is merely exemplary of a product that can be formed from a creased sheet of planar material, wherein the planar material has been cauterized to form the crease with the apparatus of the present invention.
  • the product shown in Fig. 5 can be incorporated, for example, into a ceiling panel 29 as shown in Fig. 3 of the type described in more detail in the aforenoted provisional patent application.
  • planar material 18 to be creased in accordance with the present invention may be provided in rolls or in flat sheets or strips such that the material can be advanced between the pair of confronting drums 12 and 14.
  • the sheet or strips of material to be creased are precut to a predete ⁇ nined width that can be accommodated by the length of the rollers.
  • a material found to be particularly suitable for cauterizing in forming crease lines with the method and apparatus of the present invention includes glass fibers imbedded in an acrylic resin with the fibers preferably being relatively long and thin.
  • the length of the glass fibers would preferably be in the range of one quarter inch to one inch.
  • the thickness of the glass fibers would preferably be in the range of seven microns to one- hundred microns, with fibers of ten to sixteen microns having proven to be particularly desirable.
  • a material found suitable for this purpose is 100 GSM glass mat, number 8802 manufactured by Johns Manville of Waterville, Ohio; or an alternative would be materials from OJI Glasper in Japan and also Ahlstrom in Finland.
  • the drums 12 and 14 are disposed above and below the strips or sheets of material and mounted for rotation on axles 28. Both drums are formed from a metal cylinder 30 and have an outer electrically insulating covering 32.
  • the covering or outer sleeve 32 may be made of silicon rubber which would preferably have a durometer rating of approximately 80.
  • the drums have a plurality of electrically conductive wires 34, such as nickel chromium, extending along their length with the wires being connected to an electrical source (not shown) so that they can be energized and de-energized in a short period of time whereby the wires function as quick heat filaments, but upon deactivation lose the heat very rapidly.
  • the insulating sleeve insulates the metal drums from the nickel chromium wires so that the drums do not heat up between the wires.
  • the nickel chromium wires 34 are engaged with the material at preselected intervals corresponding to the distance around the periphery of the cylindrical drum that the wires are positioned.
  • the wires come into engagement with the material 18 along a line of alignment between the two cylindrical drums 12 and 14 which is within an imaginary plane passing through the longitudinal axes of the drums.
  • the nickel chromium wires are energized imrnediately before engagement with the strip material to cauterize the crease position on the material and de-energized immediately thereafter for cooling the wires.
  • one of the upper or lower drums 12 or 14 would not be provided with the electrically conductive wires. It is also possible that ultrasonics or lasers could be used to crease the material again by cauterizing the resin base without damaging the glass fibers in the strip material.
  • the creases are provided at locations where the strip or sheet material is to be folded and these locations are spaced from each other consistently with the spacing of the wires around the circumference of the cylindrical drums.
  • the wires need not necessarily run along the length of the drum on which they are mounted but could run pe ⁇ endicularly thereto or even at an angle relative thereto depending upon the location and orientation of the crease desired for the strip or sheet material. In some such cases the wires may be continuously energized.
  • a plurality of wires 34 which are each elongated loops, running along the length of the drums, are in engagement with non- conductive rings 36 having conductive pads 37 at a location adjacent to the line of alignment between the two drums.
  • the rings are positioned at one end of the drums 12 and 14 with the rings being in engagement with conductive brushes 38 at each end of the looped wires.
  • the conductive pads 37 on the rings are in turn connected to a source of electricity through an appropriate switching system 38 which selectively controls the flow of electricity to the pads 37.
  • the wires are thereby energized and de-energized in pulses as they are rotated by the line of alignment between the drums and come into engagement with the planar material.
  • the depth of the crease provided in the sheet or strip material 18 can be regulated by the diameter of the wire 34 or the spacing of the drums 12 and 14. While it is preferable that the drums both be driven at a uniform speed but in opposite directions, i.e., clockwise and counterclockwise, it is possible that one of the drums could be an idler while the other is driven or if there is enough frictional engagement between the sheet or strip material and the drums, the sheet or strip material could simply be drawn between the drums and both drums could be idler drums which are forced to rotate uniformly through frictional engagement with the sheet or strip material which is being pulled therebetween.

Abstract

L'invention concerne un procédé et un appareil (10) de plissage d'un matériau plan (18), dans lesquels on utilise une paire de rouleaux opposés (12, 14) entre lesquels on fait passer le matériau. Un filament électrique (34) conçu pour pénétrer dans le matériau plan à mesure que ce dernier passe entre les rouleaux, et pour faire fondre ledit matériau sur une profondeur prédéterminée (24), est prévu sur au moins un des rouleaux. Les filaments sont de préférence à chauffe rapide et dissipent rapidement la chaleur, si bien qu'ils peuvent être activés et désactivés à intervalles rapprochés, de manière que les rouleaux sur lesquels les filaments chauffants sont montés ne chauffent pas entre les filaments .
