A yarn comprised of a number of threads twisted with each other is provided with a plurality of feathers, the quill portions of which are tightly inserted into twisted threads and the feather portions of which project outwardly from the twisted threads to form a bird feather-shaped covering of the yarn.

The invention concerns a yarn brake (B) comprising a brake (L) electromagnetically stressed against a fixed braking surface (17), a housing (1) whereon the cover bearing the brake (L) is mounted such that it is capable of being lifted relative to the fixed braking surface (17), and at least an adjusting arbor (S) controlling the lifting movements of the cover, said arbor being mounted on the housing (S) in geometric association to the path of the yarn (W). The invention is characterised in that ...

A yarn carrier is provided in the form of a yarn winding tube having a yarn catch insert. The yarn winding tube is a hollow cylindrical tube having a longitudinal axis extending lengthwise between its first and second opposite ends. The tube has a hole through its surface for receiving a yarn catch insert. The yarn catch insert includes a first member and a second member, each having an inside surface. When positioned within the hole, the inside surfaces of the first and second members face each...

A yarn sensor for optically scanning a yarn (3), traveling longitudinally through a measurement gap (19), includes a light source (20) projecting a beam of light into the measurement gap (19), at least one receiver (23) for directly transmitted light, and light transmitting elements (24, 25, 26, 27) transmitting the light between the light source (20), measurement gap (19), and receivers (21, 22, 23). The light source (20) is an emitter with Lambert's emission characteristics. The light-transmit...

A yarn carrier (30) for presenting a selected yarn (16) to a pair of gripper jaws (26,28). The yarn carrier (30) includes a yarn guide passageway (14) defining a path along which the selected yarn (16) is longitudinally guided. The passageway (14) has a yarn inlet end, a yarn outlet end and adjacent to the yarn outlet end yarn guides (32) to constrain the tail of the yarn (Y.sub.T) against lateral deflection in a longitudinal direction of the yarn carrier (30). The yarn guides (32) are depressib...

A yarn sensor for textile spinning and bobbin-winding machines for optically scanning a longitudinally traveling yarn (3) within a measurement gap (19), particularly for detecting extraneous fibers, includes a light source (20), a first receiver (23) for directly transmitted light, two further receivers (21, 22) for light reflected from the yarn (3), and light transmitting elements (24, 25, 26, 27) between the light source (20), measurement gap (19) and receivers (21, 22, 23). In the absence of ...

A yarn cleaner for cleaning defects from a yarn, by means of a head for measuring at least one yarn parameter for comparison against cleaning limits determined for the yarn parameter. If the cleaning limits are exceeded, a defect in the yarn is indicated whereby intolerable defects may be cut out from the yarn. The yarn cleaner is set up for cleaning an effect yarn, also called a novelty or fancy yarn, formed from an alternating thinner webs and thickened effects in the yarn. At least one value ...

The invention relates to composite yarn of bright color. It is obtained from yarn or fibers of at least two types, yarn or fibers of bright color and temperature-stable and/or smothering yarn or fibers. The yarn and the textile articles obtained from said yarn provide excellent protection against heat and/or flame.

A yarn feeder for circular knitting machines that have a plurality of knitting needles includes a first threading hole, a second threading hole and a jutting yarn guiding member on a lower edge for feeding three yarns corresponding to a knitting needle. The three yarns enter a hook of the knitting needle through the first and second threading holes and the yarn guiding member. The hook is a common point, forms a first included angle with the yarn guiding member and the first yarn threading hole,...

There is disclosed a method of texturing yarn products wherein the yarn product is passed along a predetermined yarn path through a liquid jet device applying a force to the yarn transversely to the axis thereof, comprising directing the liquid as it passes through the liquid jet device past an air inlet to the liquid jet device to entrain air therein.
