Abstract
The invention relates to a covering for drafting rollers of spinning machines, which consists of an outer and of an inner layer. The outer layer (1) is harder than the inner layer (2) and has a thinner wall than that of the inner layer, and the drafting roller is pressed as a pressure roller against a fluted steel cylinder (5). The outer layer loosely (6) surrounds the inner layer whereby enabling the outer layer to move relative to the inner layer.
Claims2
A roller drafting device for spinning machines in which the covering for the pressure rollers consists of an outer and an inner layer and the outer layer has a thinner wall than the inner layer, characterized in that the outer layer (1, 10, 100) loosely surrounds the inner layer (2) so that the outer layer (1, 10, 100) can move relatively to the inner layer (2).
