<p>In a circular knitting machine, means for tensioning the fabric as it is knitted, comprising one or more reciprocating resilient annular members within the needle cylinder for alternately trapping and downardly tensioning the fabric as it passes over the guide surface of a throat piece. Immediately thereafter the fabric is drawn further downwardly over a smooth annular rim of a suction tube, and entrained upwardly through the suction tube by air flow, thereby obtaining an even mechanical downward tensioning while drawing the fabric off upwardly.</p> |
