  • Patent number: 4520851
    Abstract: The taker-gripper has a longitudinally translatable clamping tongue with a clamping tongue head. The latter is pressed by a spring into a clamping hook having a first diagonally oriented or inclined clamping flank. The weft or filling thread is thereby firmly gripped and pulled through the weaving shed. The clamping hook has a further clamping flank oriented diagonally or at an inclination in reverse relation to the diagonal or inclined orientation of the first clamping flank. A correspondingly located inclined or diagonal flank of the clamping tongue head slidingly engages the further clamping flank of the clamping hook as the clamping tongue opens. As the parts of the gripper move into the open position, a pivoting motion of the clamping tongue about a pivot pin is generated by an eccentric engagement of a tension band at the clamping tongue in relation to the pivot pin.

  • Patent number: 3958608
    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.
