ABSTRACT:
A sewing unit for withdrawing web material, of the knitted type, from a source, folding it and then seaming one side to place it in tubular form. The apparatus includes a triangle unit for folding the web material as it is received from its source and then advancing it into operative association with a tentering member about which it extends. From the tentering member the folded material is advanced to the sewing zone of a sewing machine and then advanced to a position whereat the tubular material is wound onto a take-up roll. An elongated bar member being selectively adjustable relative to positions inclined from a horizontal plane is adapted to engage and raise the lowermost portion of the folded material whereby it is caused to be displaced toward the machines line of sewing.
