Abstract
Apparatus for tacking a yarn in a predetermined pattern onto a needled fleece, which lies on a support consisting of brushes and which is supported by the free ends of the brush bristles comprising a pressure plate unit which is movable parallely to the support and having a yarn channel extending basically vertically therethrough, yarn supply structure for supplying the yarn along a yarn path from a yarn supply into the yarn channel, a needle having laterally protruberant projections, which are suitable for piercing yarn fibers into the needled fleece, a needle support connected to the pressure plate unit and mounting the needle, and drive structure for moving up and down the needle support in a direction towards and from the pressure plate unit. The device is suitably combined with a needle loom, which pierces the fibers of the yarn tacked to the needled fleece by the device through the needled fleece. (FIG. 1)
