Abstract: There is disclosed a mop head sheet-like fabric formed of a plurality of folded and twisted cords on each side of the midline of the fabric which are in side-by-side abutting relation to one another and have looped ends, the cords being bound together by a tape on each side of the midline adjacent to and inward of the looped ends, wherein the tapes have been perforated through with a patterning of needle holes; the fabric may be in a continuous form such as is sheeting and of a prescribed width, being that of approximately twice the length of the constituent cords. The fabric is easily handleable as is sheeting. Further disclosed is a continuous process for forming the present fabric, employing porcupine rollers to control the twisting of the cords and their side-by-side orientation, as well as their taping. Yet further disclosed is an apparatus for carrying out the process employing the aforesaid porcupine rollers.

Abstract: The spindle assembly is of the type having a spool upon which coils of strand material are formed preparatory to doffing of a strand package from the assembly. The coils are formed without overlapping them upon one another, and preferably without permitting their transverse engagement and possible mutual attachment. First and second oppositely directed helical grooves are respectively provided upon upper and lower portions of the spool. The first groove prevents overlapping and transverse attachment of the strand material as the coils are formed. Both grooves position strand material at a location favorable to clearance from the spool.

Abstract: Independently actuable underwinding clearers are mounted adjacent to those lower portions of the machine's spindle assemblies upon which yarn underwindings are placed preparatory to the formation of yarn packages upon the upper portions of the spindle assemblies. Upon actuation thereof during each cycle of package building operation of the textile machine, the clearers separate the lengths of yarn interconnecting the underwindings with the yarn packages undergoing formation upon the spindle assemblies. The clearers preferably are actuated sequentially and pneumatically. A preferred mode of actuation of the clearers is by blasts of air emitted from a mobile servicing apparatus, such as a conventional pneumatic traveling cleaner, during movement of the apparatus along the length of the textile machine.

Abstract: First suction forces of relatively large magnitude and small duration, and second suction forces of relatively small magnitude and large duration, are alternatively applied to the trash outlet of each trash box of a multi-station open-end spinning machine during its operation. The large-magnitude suction forces rapidly evacuate from each box trash previously introduced therein by a beater roll disposed adjacent its inlet. The small-magnitude suction forces discourage escape of the trash from the boxes, pending evacuation thereof. Preferably the small-magnitude suction forces are applied simultaneously and substantially continuously to the outlets of all of the trash boxes, and the large-magnitude suction forces are applied successively to discrete groups of the boxes.

Abstract: The invention is employed to convey and break spin fibers and involves a single cylindrical opening means which separates a fibrous bat into individual fibers. A suitable feeding means is operably associated with the opening means and serves to feed the fiber bat to the opening means. A plurality of conduits open adjacent to the peripheral surface of the cylindrical opening means and each conduit extends to a discrete location remote from the opening means. Fibers are drawn from the peripheral surface of the opening means into and along the length of the conduits by a suction introduced through a vacuum manifold opening into the conduit. Connected to each of the conduits remote from the opening means is a break spinner which spins into yarn fibers conducted from the opening means.
