ABSTRACT:
A drawing mechanism for the doubling and drafting of fibre slivers, has a drawing mechanism frame for accommodating the drawing mechanism, which has at least two pairs of rollers each comprising an upper roller, and a lower roller, and has means for adjusting the spacing of at least one of the lower rollers in relation to another lower roller, in each case having a mounting device for accommodating the lower roller, wherein lower rollers are arranged to be driven by a drive device comprising at least one drive element endlessly revolving around pulley wheels.In order, by simple means in terms of construction, to make possible a considerable reduction in the work and time required for adjustment of the lower roller(s) and, accordingly, of the extent(s) of the drawing zone(s), the mounting device(s) are made adjustable by the drive device.
