Abstract: An apparatus for cutting or opening a tube of knit fabric is disclosed and includes a conveyor which moves the fabric along a horizontal axis as it enters the apparatus and continues in this horizontal path and the fabric is expanded cut and moved out of the apparatus along the horizontal axis.

Abstract: A device (15) for centering a tubular fabric (10) comprises a central fixed supporting portion (16) located within the fabric. A pair of oscillating arms (17) each having an end mounted to said central fixed portion (16), are kept divaricated against the tubular fabric. A motor driven roller unit (18) is secured to the free end of each oscillating arm (17) and has an electric motor (19). Motors (19) control rotation, in the same direction of rotation, of respective supporting members (21) each fitted with a plurality of idle rollers (22). The rollers (22) are angularly equally spaced around their respective supporting member (21) and are free to rotate about respective axes of rotation transverse to the direction of advancement of the fabric. Rotation of supporting members (21) in the same direction causes the fabric to rotate, while oscillating arms (17) keep the fabric stretched.

Abstract: Continuous production of a long bias cloth is accomplished by manufacturing a tubular fabric on a circular loom having a circular frame, reeds arranged on the frame and a shuttle for a weft rotatable along the frame. The fabric is removed from the loom under tension by a removal device comprising a primary pillar core with a plurality of caterpillars adjacent its outer periphery. Removal under tension prevents the formation of any edge portion causing folds and wrinkles in the tubular fabric. The tubular fabric is then spirally cut by a cutting device which has a secondary pillar core with a plurality of feed rolls adjacent its outer periphery. The feed rolls are capable of moving the fabric forward relative to its length, while the cutter is capable of moving circumferentially relative to fabric lengbth. A long bias cloth of high quality can be manufactured continuously, even when the warp and weft fibers used have high-strength and poor or low elongation.

Abstract: A tubular fabric (4) is withdrawn from a supply roll (3), over a spreader (5), by means of a support band (11) and a pressure band (14). The spreader (5) comprises an inner longitudinal guide member (17), and an outer longitudinal guide member (18), and are mounted on the free ends of two or more telescoping tubes (22). The inner and outer guide members are urged apart by helical compression springs and are drawn together by wire cables (26). A cutting device (41), comprising at least one circular knife (43), is disposed between the engaging projections (40) of the guide members (17,18) and the next telescoping tube (22). This cutting device cuts a longitudinal slit (49) in the wall of the tubular fabric, producing two slit edges (51, 52). The lower slit edge (51) lies on the support band (11) and is pressed so as to be held down by the inner guide member (17). The other upepr slit edge (52) lies on the upper side of the inner guide member.

Abstract: A film or fibrous web which has been stretched by moving at least two laterally spaced first longitudinal portions gripped by a first gripping means along at least two arcuate divergent paths formed jointly by at least two radially disposed first pulleys and endless belt means trained arcuately therearound, is further stretched by moving at least two laterally spaced second longitudinal portions adjacent to the first longitudinal portions gripped by a second gripping means along at least two arcuate divergent paths contiguous to the first arcuate divergent paths, respectively, formed jointly by at least two second pulleys, respectively, disposed downstream of and close to the first pulleys in coplanar relation thereto and second endless belt means trained arcuately therearound. The film while being stretched is heated to a temperature suitable for stretching with heated air and the like, or is softened by immersing in a bath of solvent or plasticizer.

Abstract: A method and apparatus for stretching a thermoplastic polymer film in which the opposite selvages of the film are gripped by gripping means and are stretched transversely during heating by moving the selvages along two divergent arcuate paths lying in the same plane and extending over a predetermined circumferential range from a quater to a half of the full circumference of the circle containing the arcuate paths. In order to avoid drawbacks in the existing equipment such as irregular molecular orientation in and rupture of the film, the longitudinal travel of the film while being stretched is controlled by controlling means so that the central web portion is advanced by substantially the same distance as the gripped film selvages, whereby the amound of longitudinal movement of the film is held always constant throughout the width of the film.

Abstract: Longitudinal and transverse stretching of a tubular film is effected by gripping opposite selvages of the tubular film between a pair of substantially coplanar pulleys and a pair of endless belt means trained arcuately around the pulleys, respectively, and by rotating the pulleys at a peripheral speed greater than a speed of feed of the tubular film. As the film selvages progress along a pair of arcuate divergent paths, respectively, around the pulleys, the film is heated, reversed in direction of travel, and cut along the selvages into a pair of biaxially stretched sheets. Before stretching of the film, live steam is introduced into the tubular film for heating the same.

Abstract: A machine to process fabric knit in tubular form which includes apparatus to lay down a stripe of a gumming composition to allow the tubular fabric to be slit in the center of the solidified gumming stripe. The slit knit fabric is then opened up to full width and taken up. The tubular knit goods are conveyed through the gumming and slitting operation by a four belt conveying system which allows the lengthwise tension and the width of the tubular fabric to be controlled.

Abstract: Fabric spreader for knitted goods on a circular knitting machine. The fabric spreader is provided with expanding wings which are pivotably and adjustably supported on a fabric spreader frame and are adjustably spring-loaded with respect to the force generated by the knitted goods being taken up.

Abstract: An improved circular knitting machine which provides for semiautomatic doffing of large diameter rolls of knit fabric. The doffing of the fabric can be accomplished by a woman operator without strain. The knitting machine has a unique spreader bar to allow slitting of the fabric for inspection purposes while the fabric is being knit. The unique spreader bar includes a support member having a wheel member and a convex portion adjacent the wheel member to guide a fabric around the wheel.
