ABSTRACT:
A tufting machine having corrugated yarn tension rolls for pulling out the slack from the yarn. The tension rolls are mounted in pairs and supported at their ends in bearing brackets. The pair of brackets at each end of the roll pair are hinged together so that one may be pivoted relative to the other. A quick release clamping member preferably having an expandable diameter pin and a cam handle connect each pair of brackets together and act to rapidly disconnect them upon turning of the handle. An adjustable screw is provided to adjust the separation between the rolls.
