Patent number: 4392341Abstract: A twisting machine for twisting several filament yarn strands which are preferably an aramid (aromatic polyamide) and wound on spools, has a creel for supporting the spools, a delivery system which includes several feed rollers, and a first thread guide which is supported before the delivery system along the strand paths for movement back and forth in directions parallel to the axes of the delivery rollers. The first thread guide is a cylindrical first guide roller which has a circumferential guide groove for each yarn strand and is rotatable about an axis which extends parallel to the feed roller axes. A second cylindrical guide roller is arranged following the delivery system along the strand paths, is freely supported for rotation about an axial movement along an axis which is parallel to the feed roller axes, and has a circumferential guide groove for each yarn strand.Type: GrantFiled: May 18, 1982Date of Patent: July 12, 1983Assignee: Saurer-Allma GmbHInventor: Werner Grill

Patent number: 4381638Abstract: The present invention concerns the production of fancy yarns, in which during open-end spinning a roving is supplied program-controlled to the spinning unit for the yarn to be produced. According to the invention at least one roving bobbin is supported by a support member, which is detachably arranged on a can used as a receptable for the fibre material to be processed. The bobbin creel used up to the present for the bobbins impairs the accessability of the winding locations for the fancy yarn produced. This creel, according to the invention, no longer is required. Thus, the cumbersome mounting and dismantling of the creel in changing over from normal yarn to fancy yarn and vice-versa is dispensed with. According to the invention the alterations required for such changes of the yarn production mode are extremely simple.Type: GrantFiled: September 8, 1980Date of Patent: May 3, 1983Assignee: Rieter Machine Works LimitedInventor: Per O. Olsson

Patent number: 4369622Abstract: A method is disclosed for drawing and blending textile fiber and conductive metal filaments. The method is characterized by feeding at least one bundle of a first textile material through draw rollers of a drawing frame, unwinding at least one roll of a bundle of second material in the form of conductive fibers adjacent the first pair of rollers of the drawing frame, feeding the conductive fiber bundle into the back rollers of the drawing frame simultaneously with the textile material fiber bundle, and guiding the textile material fiber bundle and the conductive fiber bundle relative to each other such that the latter continuously cushions the textile material fiber bundle with respect to the draw rollers when passing therethrough.Type: GrantFiled: March 24, 1980Date of Patent: January 25, 1983Assignee: Riegel Textile CorporationInventors: Richard K. Teed, Arther M. Pressley

Patent number: 4355749Abstract: A filament-feeding apparatus for a wet freshly dyed yarn has a feed wheel centered on and rotatable about an axis and having a pair of side parts having generally circular peripheries lying in parallel spaced-apart planes perpendicular to this axis, and a plurality of angularly spaced center parts axially bridging the side parts and having outer edges axially aligned with the peripheries. The wheel is open and free of structure in zones radially inward of the peripheries and radially outward of secants extending between the outer edges. A flexible endless belt having a width equal at least to the axial spacing between the peripheries is held by a plurality of pulleys in a circular arc radially against these peripheries so that the belt forms upstream and downstream nips at the ends of the circular arc.Type: GrantFiled: October 1, 1980Date of Patent: October 26, 1982Assignee: Hacoba Textilmaschinen GmbH & Co. KGInventors: Karl-Heinz Wulfing, Werner Engelhardt

Patent number: 4332130Abstract: An apparatus for infeeding textile band material to a consumer, especially for infeeding a sliver deposited in a can to a spinning machine, comprising a transport tube extending between a feed location and a consumer. There is provided means for generating, within the transport tube, an infeed flow or current which flows in the direction of the consumer. Also, holder means are operatively correlated with an inlet opening of the transport tube in order to hold a starting portion of the sliver or other band-like material, such holder means enabling seizing of the starting portion of the sliver with the aid of the infeed flow.Type: GrantFiled: June 30, 1980Date of Patent: June 1, 1982Assignee: Luwa AGInventors: Hermann Gasser, Paolo di Benedetto, Johann W. Ferri

Patent number: 4329840Abstract: In a method of and apparatus for feeding a tow to a textile machine, the leading end of the tow is automatically twisted by a vortical gas flow during transport through a tube to the machine. Preferably the vortical gas flow is also used to draw the tow through the tube.Type: GrantFiled: June 30, 1980Date of Patent: May 18, 1982Assignee: Luwa AGInventors: Hermann Gasser, Paolo Di Benedetto, Johann W.

Patent number: 4290170Abstract: Device for aligning and attenuating soft or brittle fiber mats employing a rotating vacuum roller for gently grasping the fiber mats under sufficient compressive force to hold the same without breaking or otherwise damaging the fiber mats.Type: GrantFiled: March 27, 1980Date of Patent: September 22, 1981Assignee: Union Carbide CorporationInventors: David S. Brookstein, Alton R. Colcord

Patent number: 4240594Abstract: A creel for a twisting machine includes an arm which is pivotally mounted at its upper end to a point on a support over an aisle alongside of the machine and which secures at its lower end a peg supporting element which may be arc shaped. The creel normally is latched in a stowed position above the twisting machine not blocking the aisle, and in this position yarn from spools on the pegs of the creel is supplied to the twisting machines. When it is desired to remove the empty spools and replace them with full ones, the latch is released, whereby gravity causes the creel to swing to a second position, this one over the aisle adjacent to the machine and sufficiently lower than the stowed position that the spools easily are accessible to an operator.Type: GrantFiled: March 16, 1979Date of Patent: December 23, 1980Assignee: RCA CorporationInventor: John M. David, Jr.
