ABSTRACT:
A needling apparatus for making a patterned felt web comprises at least one needle board, which is connected to a needle board drive, a feed drive for feeding the felt web through a felt guide between a felt support and a stripper, and means for adjusting the stroke position of the needle board relative to the felt guide between an idle stroke position and a working stroke position for the largest depth of penetration. To permit an increase of the average feeding speed along a series of patterns, the feeding speed imparted to the feed web by the feed drive is adapted to be controlled in dependence on the stroke position of the needle board relative to the felt guide in accordance with a predetermined coordination between the stroke position of the needle board and the feeding speed of the felt web.
