A sliver compactor is provided between a drafting roller of a drafting frame and the delivery unit which supplies the sliver to the spinning stations of the spinning machine. The sliver compactor has a shielding element juxtaposed with the perforated moving surface to which suction is applied and which reduces the suction force required to draw the fibers of the sliver into a compact form. The shielding element extends over a plurality of slivers and the respective spinning stations and a number of such shielding elements may be aligned over the length of the machine below the stretching field plane and secured on the machine frame.

Drafting frame for a spinning machine

A drafting frame for a spinning machine, especially a ring-spinning machine can be readily retrofitted with a compaction device adjacent the last pair of drafting rollers if the condensing zone is defined between a clamping location formed by the nip of the last roller pair and a clamping location formed by a number of elements of the compacting device against the upper roller of the last roller pair.

A method and device for the production of core yarn (,), whereby a core yarn (,) is brought to a fiber slubbing (,) which has been refined in a drafting system before said slubbing is reinforced by twisting. The core yarn (,) is embedded in covering fibers. The fiber slubbing is compressed in a compacting device (,) after the core yarn (,) has been brought to the slubbing and before twisting occurs.

Method and spinning machine for the production of core yarn

Singled fibers from a fiber strand, separated by a rotor, are collected by suction on a continuously moving surface of a perforated belt or rotary drum. The fiber packet is not formed with a twist in this region and, only upon transfer to a downstream region is the twist applied, e.g. by a ring spindle.

Method of and apparatus for producing a textile yarn

Below a ring-spinning spindle, a clamping ring and a clamping sleeve have frustoconical surfaces, at least of one first textured to increase the grip on an underwinding thread. The clamping sleeve, for example, may be spring-biased to axially engage the clamp and force may be required to open the clamp.

Method of and apparatus for clamping the underwinding thread of a spinning spindle

A yarn is made on a pot-spinning machine by drafting a roving and then condensing the roving via a suction roller or belt before the yarn is twisted on a pot-spinning station.

Method of and apparatus for producing a yarn on a pot-spinning machine

A yarn is produced by condensing and compacting the roving after its passage through a drafting frame by suction rollers or suction belts and then twisting and winding up the yarn without the formation of a thread balloon on a ring spinning station with a balloon-limiting finger or crown.

Method of and apparatus for producing a yarn on a ring-spinning machine

To produce a mock yarn which is similar in appearance to a true yarn with respect to the ability to discern the components of the mock yarn after the twist has been imparted to the mock yarn, the rovings or slubbings forming the mock yarn, after drafting separately but parallel to one another in a drafting frame, are subjected separately to condensing and compaction by suction rollers or belts provided with rows of perforations. Thus compacted and condensed rovings are then combined, twisted and wound up as mock yarns. A core thread can be introduced into each roving or into at least one of the rovings upstream of the last pair of drafting rolls or immediately upstream of the condensing unit for a core mock yarn.

Method of and apparatus for making a mock yarn

A spinning machine in which downstream of the drafting frame and as part thereof, beyond the output rollers thereof, a suction roller is provided above the roving and cooperates with at least one counterroller below the roving to condense the roving before it is wound up on a ring-spinning or pot-spinning station.

An underwinding thread clamp for a spindle of a ring spinning or ring-twisting machine has a clamping sleeve biased by a spring against and juxtaposed with a collar on the spindle. The juxtaposed surfaces of the spindle and collar have wavy contours so that, upon engagement of an actuating member with each collar, the latter is cammed into its open position to release the respective underwinding thread so that the latter, engaged when a full bobbin was removed, can be released. The clamping of the underwinding thread permits the thread to be wound on the newly mounted core sleeve.

Underwinding-thread clamp for a ring-spinning or ring-twisting machine

A spinning machine having a drafting frame, a condensing unit at the downstream side of the drafting frame and a spinning station for winding up the yarn and imparting twist to the roving in forming the yarn. The condensing unit comprises a disk-shaped suction rotor oriented in a plane tangent to the output rollers of the drafting frame. A limited compaction zone is formed by a shield within a suction rotor and designed to apply suction only to a limited portion of the perforated periphery thereof. The pressing roller bears against the suction rotor at the downstream side of the compaction zone.

Spinning machine with condensing suction rotor for a drafting frame

A drafting frame for a spinning machine has a compaction unit at the downstream end of the drafting path which can be removed and other rollers and belts of the upper and lower arrays can be advanced as required to maintain the length of the paths of the sliver.

Thread breakage rates of a ring-spinning machine are measured successively and/or from different zones at the spindle stations and a thread guide between a headpiece of each spindle and the output rollers of the drafting frames can be vertically adjusted in response to a difference in the thread break rates.

Method of operating a ring-spinning machine with vertically shiftable

To allow the gap between a pair of belts and the output pair of rollers of a drafting frame for a textile machine to be reduced, the sliver compaction funnel which is disposed at the inlet side of the nip of the output pair of rollers is mounted on an arm which extends alongside the upper rollers or upper belt. The funnel can be mounted on two arms which straddle the ends of the upper roller or upper belt.

Silver compactor in the stretching frame of a spinning machine

A ring-spinning machine has spindles with head pieces, e.g. with fingers about which the yarn can be wound to reduce the ballooning of the yarn around the respective spindles. The thread-guide eyes above the headpieces can be depressed against a spring force from normal positions to enable the yarn to wind around the fingers and the spring force restores the eyes to their normal positions, thereby avoiding changes in the distances between the normal positions and the headpieces which may alter the spinning properties and yarn quality.
