Traversing apparatus for traversing a longitudinally moving yarn which is to be wound up throughout a traversing stroke

摘要

A yarn guide member is driven by an entrainment member in a predetermined direction of movement of a belt run of a belt with which there is connected the entrainment member. In a stroke reversal zone the entrainment member is reversed in its movement by the belt moving around a reversing roller and there is thus released the yarn guide member from entraining engagement by the entrainment member. The yarn guide member, while then in so-to-speak free flight, strikes a housing wall operative as an impact wall. The yarn guide member thus changes its traversing direction. After having impacted the impact wall the yarn guide member returns to the entrainment vicinity of the entrainment member which in the meantime has begun its movement along the belt run now located opposite to the first mentioned belt run as the entrainment member rotates around the reversing roller. The impingement of the yarn guide member is taken up mechanically by the impact wall and thus does not affect the entrainment member, and the yarn also is positively guided at the reversal positions.
