    • A flap mechanism includes elements for compensating tolerances and shrinkage of the flap. The compensating elements include a flap edge which is applied to the flap by assembly injection molding after the flap has cooled, thereby decreasing any gap produced between the flap and a surrounding frame by shrinkage of the flap. In addition the flap has a flap shaft which can be journaled in the frame through a conical region on the shaft such that axial shrinkage of the shaft to produce a mounting which is free of play. This construction makes it unnecessary to use additional sealing elements at the mounting locations of the flap, and the flap is also prevented from vibrating in its mounting which, in a worst case scenario, could lead to destruction of the flap.
    • 翼片机构包括用于补偿翼片的公差和收缩的元件。 补偿元件包括翼片边缘,其在翼片冷却之后通过组装注射成型而施加到翼片,从而通过翼片的收缩减少翼片和周围框架之间产生的间隙。 另外,翼片具有翼片轴,该翼片轴可以通过轴上的锥形区域轴承在框架中,使得轴的轴向收缩以产生不起作用的安装件。 这种结构使得不需要在翼片的安装位置处使用附加的密封元件,并且还防止翼片在其安装中振动,在最坏的情况下,翼片可能导致翼片的破坏。

    • A method for the production of a knitted material and a warp knitting machine for realizing the method is being described by which longitudinal conveyors are driven in such a manner so that the longitudinal conveyors are driven at least partially intermittently and/or continuously with at least at times varying speeds so that the weft threads are being guided into the area of the knitting needles according to a pattern and at arbitrary points in time and one after the other in arbitrarily desired numbers which will result in an indefinitely long and freely selectable weft thread pattern repeat. According to a further aspect of the invention an arrangement is being described in which the arrangement includes a warp knitting machine having a separate frame. On the frame, that is, independent from the warp knitting machine there is arranged a weft thread insertion system having a servo motor drive including an associated weft carriage and a weft carriage guide, weft thread off-set rakes having their own servo motor drive and longitudinal conveyors with their drive as well as a longitudinal conveyor frame. The drive for the longitudinal conveyors, however, is obtained independently from the machine drive but is computer controlled so that the longitudinal conveyors execute a movement, at least between individual weft threads, at least partially intermittently and/or continuously with at least at times varying speeds.
