ABSTRACT:
A tubular knit fabric descending from a knitting head is spread and flattened by a fabric spreader disposed within the fabric just above a pair of take-down rolls forming a nip through which the fabric passes. The spreader comprises a generally flat frame formed by tubular members. The tubular members include a pair of U-shaped sections having open ends spaced apart and facing each other, and having closed ends defining opposite fabric-engaging edge surfaces of the frame. First legs of the U-shaped sections are telescopingly and adjustably joined to a tubular center section, the center section and first legs collectively forming a roll-engaging member for pressing the fabric against the take-down rolls. The width of the spreader is adjusted by releasing screws fixing the center section to the U-shaped sections, sliding the U-shaped sections inward or outward, and using the screws to fix the frame at the new width. The roll-engaging member preferably has a diameter of about 70 to about 100 percent of the diameter of the take-down rolls. Fabric tension can be varied by adding weight to or removing weight from the interior of the roll-engaging member.
