Traversing motion for use with apparatus for winding continuous elongate elements.

摘要

In a traversing motion for winding operations a scroll cam is provided with a helical groove (6) for guiding a cam follower assembly (8) which then reciprocates to guide the winding operator. The cam follower assembly has two cam followers: an elongate follower (1) and a non-elongate follower (9). Correspondingly, in its end regions, groove (6) is widened to allow passage of elongate follower (10) and, at least in the end regions, a further groove (23, 24) is provided for non-elongate follower (9). Allows acceleration with a sharper change of direction at the end points (17) for more uniform winding.
