Abstract
A spinning plant machine has a basic drafting equipment body to receive drafting equipment which has at least two pairs of rollers, whereby each pair is constituted by an upper roller and a lower roller. A device for the adjustment of the distance between the pairs of rollers is in the form of a push rod which is coupled to the bearing arrangement of the lower rollers as well as to fix the support of the lower rollers on the basic drafting equipment body. The push rods can be adjusted with precise parallelism and position.

A textile spinning plant machine, comprising:
- a body, and a drafting device operably mounted on said body having at least two pairs of rollers each of which includes an upper roller and a lower roller;
- displaceable bearing arrangements receiving each end of at least one of said lower rollers for adjusting the distance between said lower rollers on said body;
- each said bearing arrangement non-movably coupled to a respective push rod which is non-threadedly conveyed and slidably displaceable along said body in a direction at a right angle to a longitudinal axis of its respective said lower roller;
- said bearing arrangement and push rod coupled so that said bearing arrangement bears directly and non-movably against at least one flat lateral wall of said push rod and slides directly along a sliding surface of said body;
- said push rod defining at least one non-rotational guide surface for its respective said bearing arrangement;
- and
- at least one guide element in sliding non-rotational contact with said push rod guide surface to guide and support said push rod in its direction of movement.
