Abstract

In a spinning machine with a plurality of adjacently disposed drawing or drafting roller arrangements with which the lower rollers are arranged as lower roller cylinders extending in the machine longitudinal direction, a central control device and adjusting arrangement is provided for the adjustment of the distance of the lower roller cylinders. The central control device is linked to several locations at a lower roller cylinder or to several bearing seats of a lower roller cylinder, whereby all bearing seats of this lower roller cylinder are loosened at guide holders whereby then the bearing seats and the lower roller cylinder are simultaneously brought into the desired position by activating the control device. When in the adjusted position the bearing seats are again fixedly attached to the guide holders.

Dependent claims

Spinning machine having a plurality of drafting apparatusses for drafting sliver to be spun, each drafting apparatus comprising a plurality of upper and lower drafting roller means arranged in pairs, said pairs being spaced from one another in the travel direction of sliver being drafted thereby, said lower drafting roller means including:

at least three lower drafting roller cylinder means extending in a machine longitudinal direction transverse to the sliver travel direction,
a plurality of in the machine longitudinal direction spaced bearing seats for each of said at least three lower drafting roller cylinder means,
bearing seat attaching means for detachably fixedly attaching said bearing seats to respective guide carrier means such that the bearing seats together with the respective lower drafting roller cylinder means can be moved along the carrier means to adjust the spacing between said at least three lower drafting roller cylinder means,
and central control device means including linking means engageable at a plurality of longitudinally spaced positions of said lower drafting roller cylinder means to facilitate simultaneous adjusting movement of said at least three lower drafting roller cylinder support means with respect to each other and in the travel direction of sliver.
