Traversing yarn guide for winding machines with reversing screwthread shaft having an endless screwthread groove

Abstract

A traversing yarn guide (1) for winding machines with a reversing screwthread shaft (8) having an endless screwthread groove (14), including a main body (2) which is rectilinearly reciprocably guided on two guide rails (5, 6) and which on the one hand carries a yarn guide (3) and which on the other hand has a guide projection (12) projecting into the screwthread groove (14) of the reversing screwthread shaft (8). The traversing yarn guide further comprises a shuttle (17) which is mounted pivotably on the main body (2) and which engages into the screwthread groove (14) of the reversing screwthread shaft (8). The guide projection (12) of the main body (2) is in the form of a cylindrical pin (13) which is arranged co-axially with respect to the axis (11) of the main body (2) and which is adapted with slight clearance to the cross-sectional shape of the screwthread groove (14). The shuttle (17) is of a substantially smaller height in comparison with the height of the screwthread groove (14) and is mounted pivotably in an outside groove (16) in the pin (13).
