ABSTRACT:
A sinusoidally extending groove is cut into the jacket of a roller having a smooth surface to extend in circumferential direction thereof. A flat wire is thereafter placed into the groove. Then, a first saw-tooth wire is connected to one side of the flat wire and wound around the roller. The first turn of the first saw-tooth wire is guided by the flat wire and the subsequent turns thereof are guided by the respective preceding turn. After the winding has been completed, the flat wire is removed and a second saw-tooth wire is wound around the opposite located section of the roller. For this winding, the first turn of the first saw-tooth wire is used as guide for the first turn of the second saw-tooth wire. This leads to an optimal distribution of the tips of the clothing on the roller and an improved quality of the handling or treating, respectively, of the fibres. The roller finds use in textile machines, e.g. carding machines, opening machines, scutchers, breaker cards, etc.
