Abstract: An elastic shuttle having an elongated shuttle body which has an opening to receive a filling thread bobbin, a longitudinally extending thread groove on one outer side and a recess for the introduction of thread cutters, clamping jaws arranged on the inner sides of the opening in order to hold fast the bobbin body of a filling thread bobbin, and a parting slot or line extending from one end of the opening and which makes possible a spreading apart of the clamping jaws upon change of the bobbin.
Abstract: The present device covers the winding of bobbins with filling threads, which are to be introduced in a weaving shuttle into the shed of a loom, the device having a receiving station, a winding station, and a delivery station.
Abstract: An arrangement for actuating laminas on a wave-type loom, in which the laminas are held individually by a coupling body which extends over the width of the loom, the driving of the laminas taking place by drive means arranged closely alongside each other over the width of the loom and act on the coupling body and are coupled with drive cams, the drive means being so dimensioned that the part acting on the coupling body is several times the thickness of a lamina.
Abstract: A device for supporting a rotary reed on a shaft shed weaving machine in which a rotary reed having a radially projecting profile is supported in portions of its periphery by rotary roll bodies to provide relief of the loading on the summit area of the rotary reed profile.
Abstract: A band wheel for insertion of a filling thread by alternate rotation of the band wheel formed from a hub, a wheel body connected to the hub, and having flat elements which extend for stiffening both transverse to the axis of rotation and parallel to it.
Abstract: A drive device for a carrier of a filling-thread gripper head on a loom in which the carrier is moved back and forth by a drive wheel that is rotated alternately in opposite directions through a planetary gearing arrangement, the operation of the drive device being synchronized with the movement of the batten and harness of the loom.
Abstract: A device for the filling of filling yarn bobbins on the shuttles of a traveling wave loom which has continuously rotating a conveying chain to move the shuttles having empty bobins thereon from the outlet edge to the inlet edge of the fabric during weaving, the shuttles being guided between slide rails with each bobbin provided with a small toothed wheel that meshes with a large toothed wheel to bring about the rotation of the bobbin for winding thereon a filling yarn.
Abstract: A device for improving fluid insertion of a filling thread on a loom, which device has a reciprocal pump for supplying fluid to a filling thread insertion nozzle with the plunger of the pump operatively connected to a driven cam through a spring biased transmission mechanism with means to vary the length of the stroke of the pump and the transmission mechanism being biased against the cam during the suction stroke.
Abstract: The present invention relates to a wave-type weaving machine with reed teeth which are arranged along an axis and are adapted to pivot about the said axis, abut with some play on cam-like guide surfaces and, on rotation of the guide surfaces, carry out pivoting movements about the said axis, the reed teeth beating-up the weft thread in one of the end positions of the said teeth.
Abstract: The present invention relates to devices for use in a loom for fluid insertion of the filling yarn, the loom having a reed, each of whose teeth defines a bulge with the opening of the bulge facing the fell of the cloth being woven to provide for better beat-up, all of said bulges together forming a guide channel for the passage of fluid which serves for the insertion of the filling yarn.
Abstract: The present invention relates to a shedding drive arrangement for a loom, with a dobby driving the upper and lower sheds symmetrically and with a coupling arrangement coupling the rockers of the dobby with the weaving shafts to produce a non-symmetrical shed movement. By "rockers" or jack levers there are generally understood elements which transmit the driving movement produced by the dobby and available at its output side.
Abstract: A carrying structure for supporting, for example, cable ducts, comprises vertical bearers from which project disengagable, horizontal bearer arms. Each bearer arm has at least two hooks adjacent one end thereof, which hooks, when inserted into corresponding holes of a vertical row of holes formed in a vertical bearer, engage the bearer arm with the vertical bearer. The hooks of an arm are integral therewith and project laterally of the arm surface which is in face to face relation with the hole-defining surface of the vertical bearer when the arm is engaged with the bearer. Each hook has on one of its side edges a lateral support surface above the vertical portion of the hook which engages the vertical bearer on its side opposite to the main body of the bearer arm. This support surface engages a vertical side of the hole in which the hook is inserted enabling the transmission between the bearer arm and vertical bearer of horizontal moments.
