  • Patent number: 7779869
    Abstract: A profile rod (15) preferably consisting of an extruded aluminum profile has lateral walls (18, 19) that have two snap-in zones (25, 26) that project toward each other and extend parallel to each other over the entire length of the profile rod (15) and that are located on the same height. The distances of the two snap-in zones (25, 26) from the closest strip (21) correspond to each other. In this manner, the profile rod (15) may be made extremely thin-walled, on the one hand, and offers possibilities for fastening profile pieces that permit the input of larger forces into the profile rod (15) as well as the output of such forces therefrom, on the other hand. This concept offers a basis for the construction of light-weight heald shafts that can still handle great loads.

  • Patent number: 7770416
    Abstract: To simplify the setup of a bar and associated tools of a knitting machine and to improve the degree of precision regarding fineness and the level of sturdiness of the tools and bar system, the holding parts (7, 9) of the tools (4, 5) of the tool set (2) are configured differently. On the holding parts (7) of at least one tool type, means (22) are provided for positioning the tools (4) on the bar and thus means for defining the division. Separate positioning means for positioning and defining the division may be assigned to the other tools (5). Alternatively, they may be positioned by the tools (4) of the first type, between which they are accommodated. If positioning grooves are provided in the bar or parts thereof, these grooves may be set up for twice the distance of division, which results in robust and mechanically stable solutions with finer divisions.

  • Patent number: 7762106
    Abstract: For longitudinal shifting, a needle in accordance with the invention is provided with a longitudinal slit 14 that is disposed to accommodate a bearing element (19), for example, having the form of a strip (20). Whereas known needles are set in a guide channel and thus are held or guided between two guide flanks, the needle in accordance with the invention extends around a strip (20) and is guided on said strip. Thus, the needle is guided on two surfaces of the guide element (19) and the strip (20), respectively, said surfaces facing away from each other. The support section (4) and the bearing element (19) form a highly precise positioning or guide device.

  • Publication number: 20100147035
    Abstract: A knitting machine in accordance with the invention includes a thread guide that is associated with a runner. The runner is disposed to hold open the latches of driven out needles of a first group while the needles of a second group are being driven out. Due to the time-staggered driving-out of the latch-type needles and of a first group and a second group, and due to the alternating arrangement of the needles of the first group and the second group, a rising of the knit fabric while the needles are being driven out is prevented without the assistance of holding-down/knock-over sinkers. Inasmuch as a runner that is separate from the thread guide is used for holding open the latches, the position of said runner can be optimally adjusted independent of the position of the thread guide.

  • Publication number: 20100101679
    Abstract: A clamping device (18) for temporarily clamping the fabric (2) in place is provided on the weaving machine (1), and interacts with a ventilating device (23) that effects the temporary elimination of the clamping action. The operation of the ventilating device (23) is controlled by the movement of the beat-up device (11) via a mechanical connection that exists between the beat-up device (11) and the clamping device (18), and is effected by a mechanical transmission (28)—to be understood in the broadest terms—via which the clamping force can be eliminated or also generated in some embodiments. Due to the controlled release of the fabric at times or during phases of operation of the weaving machine (1) that can be adjusted and selected, a simple adaptation of the operation of the weaving machine (1) to different types of fabric can be achieved. An operation with less longitudinal pull of the fabric is possible.
