Patent ID: 7735201

Claim:
Card wiring, comprising: a) a first carding wire including a number of rough, pointed, first teeth; b) the rough teeth including a rough surface having a first coefficient of friction; c) the first rough teeth including an attack angle and a back angle; d) a second carding wire provided adjacent to the first carding wire; e) the second carding wire including a number of smooth blunt teeth having a smooth surface including a second coefficient of friction; f) the blunt, smooth teeth including an attack angle, a back angle, and a secondary back angle; g) the first teeth are adjacent to and spaced apart from the second teeth; and h) the first coefficient of friction being sufficiently greater than the second coefficient of friction so that, in use, a fiber engaged by a rough, pointed, first tooth and by a smooth, blunt second tooth will be held sufficiently longer by the first rough tooth so that the fiber will be pulled in a direction transverse to a direction of movement of a web engaged by the first and second carding wires.
