Abstract: An apparatus for selective movement of individual lamella shaped heddles for the formation of a shed on a loom in which the heddles are positioned between flat guide elements with each heddle being selectively movable to one of two predetermined different positions.
Abstract: Apparatus for lubricating and cooling the gripper band on a shuttleless loom in which a roller containing lubricant is resiliently biased against one side of the gripper band and driven by the movement of the gripper band.
Abstract: The present invention covers a loom having means for introducing the filling threads by fluid with the means for introducing the filling threads having a comb of parallel channel forming blades to form a guide channel for the fluid, the channel forming blades arranged on the side of the reed facing the fell of the cloth.
Abstract: The present invention covers an apparatus for selecting shuttles having weft windings therein of different filling yarn types for preprogrammed weft insertions on a wave-type or corrugated shed loom.
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: 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: 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 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.
