  • Needle-drive knock-over sinker
    Publication number: 20090301138
    Abstract: A knitting system (6) wherein said system causes a rocker guide (23) to move the holding-down and knock-over sinker 5 as a function of the longitudinal position of the knitting needle (4). Consequently, the pivoting movement of the holding-down and knock-over sinker (5) is forced to follow the back-and-forth linear movement of the knitting needle (4). A single box cam is sufficient for controlling this knitting system (6). In any event, it is only necessary to allocate box cams to the knitting needles (4). The holding-down and knock-over sinkers (5) do not require dedicated drives and box cams.

  • Heald support bar of bent sheet metal
    Patent number: 7624764
    Abstract: Heald support bar for heald shafts consists of a bent sheet metal element with unbent legs (8, 9), whereby, in the bending zones, the material thickness is reduced before or during the bending process. As a result of the compression occurring during the bending process, the material thickness in the bending region may again increase slighting during the bending process and, optionally, even return to its original value. However, in any event, an increase of the material thickness beyond the original sheet metal thickness is avoided during the bending process.

  • Heddle shaft rod, heddle shaft, and method for producing a heddle shaft rod
    Patent number: 7578316
    Abstract: The heddle shaft rod (4) described originates in an extruded aluminum profile section with relatively thick side walls, which are removed in some regions and thereby made thinner. This can be done without substantial impairment to the rigidity of the heddle shaft rod, yet as a result a substantial reduction in weight is attained. The removal of material can be adapted to the local load conditions. For instance, it is possible at the ends or other force introduction points to leave unweakened thick walls, while the other regions of the side walls are milled off far enough that a uniform thinner wall thickness is attained. It is furthermore possible to vary the amount of material removed, either in multiple steps or in infinitely graduated fashion. The material removal pertains to a reduction in the wall thickness that is measured transversely to the movement direction of the heddle shaft rod.
