"Bast fiber spinning machine"

The innovation concerns a bast fiber gill spinning machine.

There are already spinning machines for bast fibers that use or several Nadelstabstreekwerke and work with wing spindles, became known.

The disadvantage of this arrangement is that the vane spindles have only a low power. When using wing spindles a weight of the package of about 1_? 5 g can be achieved, .wherein the maximum speed of vane spindles is 4,000 revolutions per minute. There is also a treatment on these machines with hot water and pre-spinning required on a pre-spinning machine.

Ring spinning machines are also known for spinning bast fibers, but they only work with draw rollers. These machines , but have the disadvantage that the fibers are only insufficiently stretched

The present innovation is based on the task of a bast fiber spinning machine consider the disadvantages of the known Spinning machines does not have and is particularly suitable for dry and semi-wet spinning of bast fibers, high performance has good yarn quality and is simple in its construction.

The solution to the problem on which the present innovation is based is achieved by combining a gill field with ring spindles that follow it, known per se, with stationary ones Ring bench and the spindle bench executing the base and layer stroke.

The structure and mode of operation of the present innovation are explained using the drawing. Herein shows:

Fig.l a section through the spinning machine according to the invention in a plane going through the spindles, and

2 shows a plan view of the mechanical flat belt drive of the spindles.

The basic structure of the bast fiber gill spinning machine consists in that the needle bar 3 * 5. " 6.7 located in the upper part of the Machine frame 1 is that the ring spindle 135,15,16,17 directly is arranged laterally under the needle bar drawing frame and that the spindle drive devices 13.2o are inside of the machine frame 1 are located.

The unstretched pasers 8 are passed through the needle bar drawing unit the insertion cylinder 2 supplied. They are then moved by the needle bars 5, which are moved in the direction of the fibers by the drive worm j5 combed, straightened and parallelized, the needle bars arriving at the pair of stretching cylinders 6, 7 being passed through the return screw 4 brought back accelerated to the pair of insertion cylinders 2 will.

After passing through the stretching cylinder pair 6, J, consisting of the printing cylinder 6 and the stretching cylinder J ₃ , the stretched fiber is passed over the cylinder Io of the bath trough and then spun. The thread is fed through the Ij? movably attached ring traveler 12 out, the ring Ij? is arranged on the fixed ring rail Io located on the side of the machine frame 1, and then wound onto the spool sitting on the spindle 15. In order to prevent the threads running from the pair of drawing cylinders to the spindle from interfering with one another, these threads are guided by balloon catchers 11 arranged vertically above spindle 15. The vertical mobility of the spindle table 17 ensures that the bobbin 14 is evenly hit with yarn over its full length. The spindle is driven by a flat belt 21 driven by the drive drum 18 and guided via the Ural swivel rollers 2o and the pulley 19 connected to the spindle 15 (FIG. 2).

The advantage of the present innovation is that the bast fiber crill spinning machine produces yarns of the same quality as produce with normal gill spinning machines with wing spindles

but with a production increase of at least $ 30 compared to the latter. When using a ring spindle According to the innovation, for example, thread bodies with a weight of up to about 400 g can be produced, while with the known wing spindles only those with a weight of about 135 g can be reached are. In addition, the ring spindle has speeds of around 7500 revolutions per minute compared to a maximum of 4,000 revolutions per minute with vane spindles. In addition, yarn numbers can be processed with the ring spindle, those with the wing spindle in no case can be processed. It falls in particular in the dry or semi-wet spinning process according to the present innovation the fact that it is not only possible to work with about twice the spindle speed, but that, moreover, the treatment with hot water and the need no need for roving on a roving machine.
