Abstract
A thread guide for yarn cleaners has a disk-like body (1) with a front plate (11) a rear plate (12) and a generally V-shaped cutout (2) of which radial surfaces (3, 4) serve as thread entry surfaces and of which the center (5) serves as thread-guide floor. The thread-guide floor (5) has a first hump (6) serving to restrict thread motion vertically from a central thread path (17), the right-hand thread entry surface (3) has a second hump (7) serving to limit lateral thread motion to the right of path (17) and the left-hand thread entry (4) has a third hump (8) serving as to limit lateral thread motion to the left of the path, the highest elevations (points of greatest protrusion) (13, 14, 15) of the three humps (6, 7, 8) being axially offset from each other.
