  • Patent number: 5167742
    Abstract: A device and method for producing a tapered scarf joint between two composites includes a cutting guide for cutting plies to incrementally variable lengths. The joint is produced on a filament winding machine having a mandrel and a winding eye for delivering tacky prepreg filament bands. A first helical ply is wound around the mandrel. Next, a cutting guide edge is positioned over the first ply an incremental distance inward from the ply end. As the next helical ply is wound, the filaments are cut at the cutting guide edge. The cut filament ends are pressed against the first ply. The process is repeated N times. The cutting guide is then removed from the mandrel, and a final ply is wound over the entire length of the composite. Similarly, the same cutting guide is then used to produce an outwardly tapered composite end. Only this time the cutting guide edge is positioned incrementally outward along a tapered wedge attached to one end of the mandrel.

  • Patent number: 4832773
    Abstract: Thermoplastic tubes are welded together in a dry condition with the tubes being open and maintained in their undistorted condition during the welding step. In an alternative technique a branch tube is welded to a main tube by placing the tubes in a non-parallel orientation in a holding device. A wafer cuts completely through one tube to form two tube sections. The wafer also cuts a notch from the other tube. One of the tube sections is shifted to become aligned with the notched other tube and welded thereto. A further technique includes placing at least one tube in a holding device which has a false floor for pressing against an area of the tube while the tube is being flattened at two spaced locations on opposite sides of the area. When the false floor is moved away from the tube a partial vacuum results. An air pocket is formed when the tube is severed by a wafer by air flowing into the cut tube.

  • Patent number: 4828194
    Abstract: An apparatus for winding magnetic tape into a cassette positions and holds a cassette case, extracts and retains leader tape, cuts and splices leader tape to magnetic tape, and winds magnetic tape onto a hub inside the cassette case. After a predetermined amount of magnetic tape has been wound on the hub, the magnetic tape is retained, cut, spliced to leader tape, and the extracted slack tape is wound into the cassette case. The tape retaining mechanism has a first and second tape retainer which separately hold the cut ends of leader tape, and a third tape retainer which holds the cut end of magnetic tape. The first and second tape retainers attach to the extracted leader tape, and are positioned with their attachment surfaces adjacent to a front cavity of the cassette case. Once the leader tape has been cut, one of the first and second tape retainers is swung away from the cavity to separate the cut tape ends.

  • Patent number: 4801342
    Abstract: A method and apparatus is disclosed for forming a butt splice to join together a web from a new roll of material to a web which is from an expiring roll of material and which is being run, downstream from the expiring roll, under tension along a predetermined path of travel that includes a running web storage means and a press or other web handling means. To form the butt splice, the leading end of the new web is trimmed along the cutting edge of an anvil. The trimmed leading end is held against the anvil, and a piece of tape is applied to the leading end so that a portion of the tape projects downstream from that end. The portion of the expiring web, adjacent to the anvil, is then momentarily stopped, held against the anvil, and trimmed along the same cutting edge of the anvil. As the trailing end of the expiring roll is trimmed, it is simultaneously adhered to the downstream portion of the tape. This serves to join this trailing end of the expiring roll and the leading end of the new roll together.
