ABSTRACT:
An apparatus for feeding an elongate surface tape or a strip of piled, plushed or tufted textile along a predetermined path has a drive roller which has a multiplicity of wire bristles planted in its surface for releasable engagement with the strip. Disposed upstream of the drive roller with respect to a predetermined traveling direction of the strip, an idler roller is also provided with a multiplicity of wire bristles for releasable engagement with the strip. The idler roller is constantly braked to hold the strip under tension as it extends over the two rollers. The wire bristles on the rollers may be either straight or bent and may either extend radially of the rollers or be inclined in prescribed directions with respect to the traveling direction of the strip.
