Test device on ring spinning or ring twisting machines for a visual test of the eccentricity between a spindle and an associated ring

摘要

The invention relates to a test device on ring spinning or ring twisting machines for a visual test of the eccentricity between a spindle and an associated ring, in which the viewing direction along the spindle axis is directed towards the spindle tip. The object on which it is based is to reduce the outlay in terms of work time in the visual testing of the eccentricity between a spindle and an associated ring. This object is achieved in that the sleeve-shaped spindle attachment (6, 7) consists of a sleeve core (6) and of a sleeve casing (7) which are displaceable relative to one another, and the sleeve core (6) has a groove (9), in which a rubber ring (10) is arranged. - Fig. 1 -. The invention achieves the technical effect that the summing tolerances of the conicity of the spindles, of the position of the spindles in the spindle foot and of the sag of the ring rail are compensated without any correction of the level of the ring in relation to the spindle.
