Open:end spun core yarn - has core filaments passed into spinning chamber to be drawn out with spun staple fibres

Yarn is mfd. from staple fibres by feeding the fibre material to the spinning chamber of an open-end spinning machine. A core filament material is also passed into the spinning chamber to be drawn out together with the spun yarn. The core material can be a single or multiple filament or of staple fibres. The core can also be a mixt. of filament and staple fibres materials. The zero point, in the false twisting of the core material, lies at the point where the staple fibres for the spun yarn are in a loose and open state. There is a separate feed for the core material into the spinning chamber, and an outlet for the spun yarn and core located centrally above the spinning chamber. The outlet tube forms the channel for the spun yarn from the chamber groove, where the fibres are twisted together, to the clamping point of the drawing -out mechanism so that the spun staple fibre strand passes from an open end of the spinning turbine to the spinning groove, with a component in the feed channel ...

Process and apparatus for combining two yarns running parallel to form one yarn

In the two gussets which are limited by two rotationally symmetrical friction elements (7, 8) of a friction spinning unit (2), two yarns (34, 35) are produced and are drawn off continuously in the direction of the arrow (36). The front yarn (34) runs successively through the two front gussets of a first (3, 4) and, if appropriate, of a second (5, 6) pair of friction elements. The rear yarn (35) thereafter runs through a deflecting device (54) and then meets the front yarn (34) at the combination point (53), whereupon the two yarns are combined to form a single yarn. Both the radially adjacent (3, 4; 5, 6) and the axially adjacent (3, 5; 4, 6) friction elements are driven in opposite directions of rotation. The casings (37 to 40) of the friction elements (3 to 6) are subdivided alternately into portions (49) of high yarn attractive power and portions (50) without any yarn attractive power.

The piecing process is carried out within preselected time intervals by means of a control unit (3a) having a change-over switch (29) connected to thread-break monitors (10) of the work units and, by means of setting members (4), to circuits of the drive means (33, 19, 20) of feeding, spinning and pick-up devices (5, 6, 17, 18) and to a vacuum source (16) in the friction-spinning machine. During the individual elimination of the thread break, the control unit having the change-over switch is connected via the thread-break monitor to the circuit of an electromagnetic coupling of the fibre supply and of an electromagnetic valve of the suction-pipe line and via the setting member to the circuit of the means for actuating the yarn take-up and/or yarn winding. ...

OFFENEND-SPINNVORRICHTUNG.

In the open-end spinning appts. a limit stop is formed by two components acting together. On unit is on the shrouding and the other unit is on the housing surrounding the spinning appts. so that they can position the shrouding in relation to the spinning appts. The fibre feed channel has an elastic sepg. surface at an angle (alpha) to the direction of movement of the moving section of the fibre feed channel. Sepg. surface incorporates an elastic ring seal, and it is at the fixed section of the fibre feed channel. The angle (alpha) between the surface and the direction of the moving section movement is not greater than 5 deg. however, not more than 45 deg.

Sensor to measure the rotary speed of an open-end spinning rotor, without contact, is within a housing in a telescopic array for setting at the end surface of the rotor support disk fitted with a permanent magnet

To measure the rotary speed of a rotor without contact, at an open-end spinner, at least one permanent magnet (37) is at a rotor shaft support disk (4) to generate magnetic field lines. A sensor (39) is shrouded within an electrically conductive and earthed housing (48) of a non-ferrous material. The sensor to measure the rotary speed of an open-end spinning rotor is within a sleeve housing of brass, which can be telescopic to set the sensor at the disk surface. The telescopic action is controlled by a setting unit (44) with a return spring (47). The sensor has an induction coil, with a ferromagnetic core to bridge the gap between the induction coil and the end side (36) of the rotor support disk. The return spring, at the sensor housing setting unit, is an electrically conductive signal transfer unit for the signals from the sensor, insulated against the housing during signal transfer. When the sensor is retracted, into the inoperative setting, the housing is short circuited with the return ...

Spinning drive device

Drive gear working on the element spinning, principle, as described in DT. P 1901453. 0, has a drive shaft which is wholly or partly kept in radial or axial direction against the guide rollers by gaseous means. Specif. the drive shaft is pneumatically pressed radially against the guide rollers by pressure jets on its radial bearings.

Open-end spinning loosening roller - fitted with grooves within toothed surface structure for loosening sliver fibres

The loosening roller incorporates grooves with a depth from the base of the toothed surface between 1/10 and 1/5 of the roller dia., and a width between 1/3 - 1/2 of the groove depth. The purpose is to prevent loose fibres and dust from building up in the gap between the loosening roller and the housing, without requiring an additional air supply from outside to keep the gap clear.
