Abstract: A ribbon loom for manufacturing a ribbon tape or the like containing warp threads and weft thread loops inserted from one side of a warp shed. A first auxiliary thread is drawn through the weft thread loops and a second auxiliary thread disposed outside of the weft thread loops is knitted with each n-th stitch of the first auxiliary thread in order to secure the same. The ribbon loom comprises a weft thread insertion element, a knitting needle for tying the weft thread loops by means of at least one auxiliary thread and a thread guide for the second auxiliary thread constructed such that for knitting the second auxiliary thread it inserts such second auxiliary thread into said knitting needle, after the knitting needle has drawn a loop of the first auxiliary thread through the weft thread loop.
Abstract: A ribbon fabric, a method for manufacturing the same and a ribbon loom for carrying out the aforesaid method, wherein the ribbon fabric or tape has weft thread loops inserted from one side of the warp shed therethrough. At the other side of the warp shed a first auxiliary thread is drawn through the weft thread loops, and a second auxiliary thread, located outside of the weft thread loops is knitted with each n-th stitch of the first auxiliary thread for securing the latter.
Abstract: An arrangement for severing webs, particularly fabrics, of thermally severable materials includes a severing tool which is mounted on a support for displacement between an extended position and a retracted position thereof, being urged towards its extended position. The severing tool has a severing portion which is heated and which contacts and severs the web during the movement of the latter longitudinally of itself in a path past the support for the severing tool. A heat-conductive member is in heat-transmitting contact with the severing tool at the severing portion thereof in the extended position of the severing tool, the heat-transmitting relationship being interrupted when the resistance of the web to the severing action of the severing portion achieves such a value that the severing tool is displaced from its extended position toward its retracted position.
Abstract: A shuttleless weaving machine, especially a ribbon loom, comprising at least one filling thread-insertion element and at least one to-and-fro driven knitting needle moving along the selvage or cloth edge which is situated opposite the filling thread-insertion element for the formation of a knitted edge by tying the inserted filling threads and/or auxiliary threads. There is further provided a deflection element operatively associated with the knitting needle for the introduction of filling threads or auxiliary threads, respectively, into the knitting region or zone of a hook of the knitting needle. The deflection element is driven so as to move back-and-forth and by means of an actuation element driven in cycle with the machine can be brought, transversely to its direction of movement, from a rest position into a knitting position where the deflection element deflects filling thread or auxiliary thread, respectively, to the knitting region of the knitting needle hook.
Abstract: A yarn transport mechanism for a needle band weaving machine comprising a carrier which can be placed into revolving motion with variable speed, said carrier possessing a friction coating against which there can be placed the yarn which is to be conveyed for the purpose of entrainment thereof.
Abstract: A web weaving machine is disclosed. The machine comprises a plurality of heald shafts disposed to have a plane of symmetry common to one another and a plurality of tension transmitting elements. At least one of the elements is flexible and is guided by at least one roller. Each tension transmitting element is connected to a respective heald shaft at a portion thereof which is disposed in the plane of symmetry and each element is so disposed as, in use, to transmit a force to the respective heald shaft which is directed substantially parallel to the healds thereof.
