Abstract (en)
[origin: EP0927781A1] The rollers have conical regions (8,9), extending from the edges of the yarn-guide groove (3) and inclined so as to converge towards the said groove (3) one of these conical surfaces (9) extending as far as an end edge (10) of the roller and the other (8) being connected to the base of the radially-projecting region (4), for establishing contact with the rollers of the drafting train. The conical regions (8,9) have the effect of automatically centring the yarn in the guide groove (3). <IMAGE>
