training mechanism for a needle in a career without borders training ship

摘要

A driving mechanism for selvage forming knitting needles in shuttleless looms is a linkage comprising a pair of upper and lower horizontal links and a pair of front and rear vertical links, these links being pivotally joined togehter to provide a substantially parallelogramatic construction. A first link extension extends from the lower link and is pivotally coupled to a machine frame. A second link extension extends from the upper link and has mounted thereon a knitting needle which is provided with a hook and a shank and is located alongside of the fabric. A disk crank has a crank pin rotatably connected to the rear link and is coupled with a drive shaft of the shuttleless loom. Rotating the disk crank swings the links so that the knitting needle is movable between a first position where the hook is raised to engage a loop of weft yarn projected through the shed and a second position where the shank is held vertically stationary adjacent to the fabric fell to knit the loop through the previous loop on the shank.
