Abstract
In card clothing for a textile machine comprising a plurality of adjacent spaced-apart needles or serrated punched cut-outs disposed in rows, wherein the needles or serrated punched cut-outs are stamped and accordingly have a non-rectangular cross-sectional geometry, wherein a free passage zone for the fibers being combed is formed between the spaced-apart needles or serrated punched cut-outs, it is provided that the free passage zone (A) steadily widens viewed in the direction of travel of the sliver.
