Abstract
The present invention relates to a sawtooth wire for a cylinder lining, in particular for a doffer cylinder for a carding machine. In order to improve the take-over and delivery properties of the doffer cylinder to a subsequent stuffer cylinder, the sawtooth wire is implemented such that the back angle of the tooth angle of the individual teeth increases from the base to the tip of the respective tooth. Owing to this tooth design, it can be achieved that the tooth back is steep in the area of the tip of the tooth, whereby the delivery properties of the doffer cylinder to the subsequent stuffer cylinder will be improved, while the breast angle is large; this will facilitate the take-over of fibres from the main cylinder that rotates at a higher speed.
