Abstract
A system for spinning thread from non-continuous fibres 1 comprising imparting a first twist stage to the thread by means of an open- end spinning head 2 and then imparting a second stage twist to the thread by means of a device 6, 7, 8 similar to that used in a ring spinning process. The resulting thread has the regularity and uniformity of open-end spun thread and high breaking strength of ring spun thread. <IMAGE>
Description
SPECIFICATION
System of spinning threads using non-continuous fibres
The invention relates to a system of spinning threads using non-continuous fibres.
Threads produced by means of the known open end or free-end spinning system, normally have a high level of regularity or uniformity and a low breaking strength, when compared with traditional non-continuous threads produced by the known ring-spinning sequence.
It is the object of this invention to provide a spinning system by means of which it is possible to produce threads having the desirable uniformity characteristic of open end spinning with high breaking strength.
According to the invention there is provided a non-continuous fibres thread spinning system characterised in that twist is imparted to the thread in two stages, the first twist stage being achieved by means of an "open end" spinning head and the second twist stage being by means of an arrangement for imparting twist similar to that used in a ring spinning sequence.
This process allows the production of threads in which the good uniformity of "open end" thread is allied with a high breaking strength. This is obtained by imparting the two-stage twist to the thread, instead of a single stage as normally carried out, the first of the said stages taking place in an "open end" spinning head or arrangement, which supplies thread with a fraction of the twist it will have when finally completed. The second stage takes place in a twist-imparting arrangement which may comprise a bobbin, a hoop and a runner ring and it is within the latter that the residual twist is preferably added to the thread. The second stage arrangement is well-known in conventional spinning carried out in a continuous ring-spinning machine.
The "open end" spinning head and the means for imparting additional twist are conveniently coupled together in such a manner as to allow continuous production of the thread.
The open end spinning head may be coupled with the means for imparting torsion or twist in various forms.
The invention will now be described by way of example with reference to the accompanying drawings in which the single figure is a diagrammatic representation of apparatus for thread spinning, constructed in accordance with the invention. In that figure the supply or run of fibres 1 from which thread is obtained, enters an "open end" rotary type head, from which a partly twisted thread 3 emerges. This led to a pair of hauling or drawing rolls 4, which in turn supply it to a twist-imparting means consisting of a thread guide 5, a runner ring 6, a hoop 7 and a rotary bobbin 8. The runner ring 6 is responsible for imparting the required twist to the thread. Rotation is imparted to the bobbin 8, through a suitable drive and as a result of this rotation the thread receives an additional twist. The completed thread is finally rolled and stored on the spindle 9 carried on the bobbin 8.
1. A non-continuous fibres thread spinning system, characterised in that twist is imparted to the thread in two stages, the first twist stage being achieved by means of an open end" spinning head and the second twist stage being by means of an arrangement for imparting twist similar to that used in a ring spinning sequence.
2. A spinning system according to Claim 1 wherein the second twist stage is achieved by passing it over a bobbin, a hoop and a runner ring, the twist being imparted by the runner ring.
3. Spinning system according to Claim 1 or Claim 2, characterised in that, an "open end" spinning head is coupled to the arrangement for imparting twist similar to that used in a ring spinning sequence.
4. Spinning system according to any one of the preceding claims characterised in that the "open end" spinning head is of a rotary type, and is coupled to the arrangement for imparting twist similar to that used in a ringspinning sequence.
5. Apparatus for spinning non-continuous fibres thread comprising, in combination an "open end" spinning head, by means of which a first stage twist is applied to the thread and an arrangement for imparting a second stage twist, said arrangement being similar to that used in a ring spinning apparatus.
6. Apparatus as claimed in Claim 5 wherein the second stage twist arrangement includes a bobbin, a hoop and a runner ring.
7. Apparatus as claimed in either of
Claims 5 or 6 wherein the "open end" spinning head is of rotary type.
8. Apparatus as claimed in any one of
Claims 5 to 7 including draw off rolls and a thread guide between the spinning head and the said arrangement for imparting second stage twist.
9. A non-continuous fibres thread spinning system substantially as hereinbefore described with reference to and as shown in the accompanying drawing.
10. Apparatus for spinning non-continuous fibres thread substantially as hereinbefore described with reference to and as shown in the accompanying drawing.
