Patent number: 4877062Abstract: The present invention refers to a temple for holding or for laterally tensioning a woven fabric, in particular on weaving looms, comprising endless guide means having displaceably arranged therein members provided with needles for engagement with said woven fabric, said guide means extending and being arranged in such a way that the needles of at least two members are simultaneously in engagement with the edge of the woven fabric and that, in the course of the needling-in operation, the needles brought into engagement with the woven fabric, are located at a greater distance from the longitudinal axis of the width of woven fabric than in the course of the de-needling operation. The failures occurring in the case of such a temple are now eliminated by providing an appropriate amount of play between the individual members and by guaranteeing at the same time that the members are returned to the point of needling-in in an appropriate manner.Type: GrantFiled: September 25, 1987Date of Patent: October 31, 1989Inventor: Tilman Hoefelmayr

Patent number: 4872302Abstract: Articles are stretch wrapped in a plastic film by forming a tube around them from a flat plastic film, sealing the longitudinal edges of the film and then longitudinally stretching the tube to cause it to constrict on the articles being wrapped. The tube is initially of a sufficient diameter to avoid contact with the articles. Both the articles and the tube are conveyed downstream. The tube is fed downstream by a positive transport means which isolates the tube forming operation from any downstream tension. A downstream mechanism pulls on the tube faster than the positive transport means conveys it causing the tube to stretch and constrict on the articles to be wrapped. The tube is closed behind each set of articles and the downstream portion is severed from the upstream portion forming a tube terminus behind one set of articles and in front of the next set.Type: GrantFiled: August 2, 1988Date of Patent: October 10, 1989Assignee: Borden BVInventors: Cornelis van Eijsden, Jan C. Mersman

Patent number: 4871134Abstract: The clip for securing a wiring harness in position has a holder portion for holding the wiring harness and a flange portion extending transversely from the holder portion for securing the clip to a fixed part of the vehicle structure. The flange portion is pivotably connected to the holder portion so that the former, in assembly, can be collapsed in parallel to the latter from the normally erect position, reducing the overall dimension of the combined clip and harness to facilitate insertion of the combination through a panel hole of relatively smaller dimension. This reduces the assembly cost and improves the assembly efficiency. Another form of clip is provided at its flange portion with a flexibly bendable constrictive portion formed in the middle of the flange portion. The clip also can be bent via the constrictive portion, reducing its overall dimension, and attains the same effect as the first mentioned clip.Type: GrantFiled: December 2, 1988Date of Patent: October 3, 1989Assignee: Yazaki CorporationInventor: Ryuetsu Oikawa
