A yarn splicing device for piecing spun yarns without knots. It contains a yarn splicing chamber and a small pipe through which fluid flows, at a distance from the yarn splicing chamber. The small pipe serves to receive a yarn end and to prepare it for the splicing process. The small pipe has a roughened inner surface which makes contact with the yarn end in a battering manner. In the process for the yarn end preparation, the small pipe is traversed turbulently by a fluid. The yarn end is battered by the turbulent flow against the roughened inner surface of the small pipe until the yarn end is free of twist.

A process and a device for the air-conditioning of spinning material located in a container. The spinning material is air-conditioned for processing in a spinning machine which is essentially surrounded by any room climate. The spinning material is exposed in the container to a climate which is independent of the room climate. This causes, at least, the spinning material to be taken next out of the container to be air-conditioned in such manner that it is in an optimal climatic state for such further processing. Outlet openings of at least one air-conditioning duct or an air-conditioning plant are located on the container so that an air-conditioned fluid flows out of the outlet openings on at least the spinning material to be taken out next and the spinning material is in an optimal climatic state for further processing as it is then processed further.

Process and device for the air-conditioning of spinning material

An air spinning device with an injection nozzle and a twisting nozzle is adjusted to the highest possible delivery speed for a desired yarn quality by predetermining the desired spinning tension of the yarn. According to the predetermined spinning tension, the highest possible delivery speed is regulated by changing the injection nozzle pressure and/or the spinning draft. Several spinning stations are installed on the air spinning device. At the spinning station, a measuring device to determine the yarn quality is installed between the twisting nozzle and the draw-off rollers. The measuring device is connected to adjusting devices of at least one spinning station. When the yarn quality is changed, the measuring device, together with the adjusting devices influences at least this spinning station.

A method for manufacturing a combined yarn, by open end rotor spinning, suitable for use in carpets is disclosed.

Combined carpet yarns by open end rotor spinning

An improved method and apparatus for stringing up or re-stringing a balanced ply-twisted combination yarn of two components to insure strong piecing-up points. The end of the combination yarn and the end of a continuous filament yarn, which becomes a component of the combination yarn, are both prepared for piecing and inserted into the rotor of an open-end spinning device. Upon start up, the combination yarn engages staple fibers in the rotor consolidating groove while the continuous filament yarn engages the combination yarn within the rotor without any contact of the continuous filament yarn with the rotor consolidating groove.

Process and device to piece to a spinning device

The invention relates to a circular knitting machine for the production of knit goods with combed-in fibers, having a rotatable, needle-bearing needle cylinder and a card which has a means for feeding the fibers, a comb-in zone through which the needles pass for the purpose of contactlessly receiving the fibers, and a teasing cylinder rotating at high speed which takes the fibers from the feed means and yields them to the comb-in zone. To prevent thin areas or thick areas from being produced in the finished goods on account of the contactless fiber loading, the circular knitting machine has a protective device (60) which becomes active in the still state of the needle cylinder for the purpose of retaining the already combed-in fiber tufts (57) in the needles (3) which are in the comb-in zone in the still state of the needle cylinder.

Circular knitting machine for producing knit goods with combed-in fibers

The invention concerns a process and a circular knitting machine for the production of knit goods with combed-in fibers, in which an amount of fibers synchronous with the needle cylinder rotatory speed is fed to a teasing cylinder rotating at high speed, transferred by the latter to the comb-in zone, and taken from the needles in the comb-in zone without contacting the teasing cylinder. To prevent the development of areas overfilled with fibers or short of fibers in the finished knit goods on account of the contact-less fiber feed, during or before abrupt reductions or increases in the rotatory speed of the needle cylinder, at least temporarily smaller or larger amounts of fibers are fed to the comb-in zone than corresponds to the synchronous amount of fibers.

Method and circular knitting machine for producing knit goods with

A method of manufacturing a combined yarn which includes feeding staple fibers to the collection groove of an open-end spinning rotor, twisting the staple fibers into a staple fiber yarn, combining the staple fiber yarn with a continuous filament yarn which is also fed into the spinning rotor and then twisting the continuous filament yarn and the staple fiber yarn together to form a balanced ply yarn.

Fiber material is conveyed over a sieve-like surface to remove dust from material. The fiber material is thereby exposed to a suction airstream which is guided through the sieve-like surface and which is guided away from the fiber material at an acute angle which is formed opposite to the fiber transport direction. The fiber material may be aligned in parallel before it is exposed to the suction airstream. In order to orient the suction airstream at the desired acute angle relative to the fiber transport direction, the fiber material is guided over sieve orifices which are inclined at the acute angle opposite to the fiber transport direction.
