Definitions
- the invention relates to a method for producing false twists from two fiber bands stretched next to one another in a drafting system, the stretched rovings of which are fed to a common ring spinning spindle after leaving the drafting arrangement and to a device for the pneumatic compression of the two stretched rags under the action of suction and a device for the production of false threads with a drafting system in which two fiber slivers stretch next to each other and, after leaving the drafting system, a common ring spinning spindle and with a surface promoting the stretched fiber lunches with two parallel perforation tracks, to which suction shoes loaded with suction are underlaid.
- DE 101 52 746 A1 shows a device by means of which the suction flow to a suction shoe of a compression device can be temporarily interrupted. However, it is about the compression of only one fiber structure, not the compression of two fiber structures combined into a false twist, in which the compression of the two fiber structures can be controlled differently.
- the object of the invention was to subject the two fiber slats to different densities in order to compress them to different extents in this way. It solves this task with the features mentioned in the characterizing part of the main claim.
- the invention achieves the object in that it completely prevents or reduces or maintains the suction pull on only one of the two fiber slips or on both fiber slats, the action on the suction pull being temporary and in fact on both fiber slits simultaneously or staggered in time.
- the compression effect on the fiber slits is varied, which leads to a different appearance of one or both fiber slits in the false thread produced.
- the fiber slats can consist of fibers of different or even contrasting colors. They can consist of fibers of different materials, in particular those that have different bulk and react differently to compaction, such as cotton and wool. The fineness of the fiber slivers can be different, so that the effect of compression also leads to different results.
- Compacting / not compacting / reducing compacting can also be controlled by a random number generator that can produce unpredictable effects.
- the compression which differs in time and in the amount of its action, in conjunction with the largely free combination of materials in the two fiber slits offers almost unlimited variants of the false thread that can be produced.
- the invention provides for separate suction chambers to be assigned to the two perforation traces of the compression device and for these to be connected to separate suction channels, in the at least one of which the suction draft can be changed.
- the induced draft can be completely prevented, not prevented or throttled more or less in any intermediate position.
- the suction channel can be connected to a suction source via an actuatable shut-off valve or an actuatable throttle valve.
- actuatable shut-off valve or an actuatable throttle valve.
- other devices known from pneumatics for influencing the induced draft can also be provided.
- the suction can also be satisfied by a bypass that can be opened so that it does not act on a perforation track.
- the drafting system 1, on which the invention is shown, has three roller pairs 2, 3 and 4 connected in series, each of which comprises the lower roller 5 and the upper roller twin 6.
- the left rollers of the top roller twins have broken away here.
- the middle pair of rollers 3 is equipped with delay straps 7.
- a compression device 8 arranged downstream of the drafting device 1 comprises a further pair of rollers 9, each with a lower roller 5 and a top roller twin 6.
- the lower roller of this compression device and a suction shoe 10 arranged in front of it are wrapped by a compression strap 11.
- This compression strap has two perforation tracks 12 spaced holes. Air is sucked through the holes in these perforation tracks through the shoe 10, whereby the fibers lying on the compression strap 11 are sucked onto the narrow perforation tracks and thereby compressed.
- the compacting device 8 can also be equipped with a rigid, rotatably driven compacting drum, which has two parallel perforation tracks on its circumference. A suction shoe separated by a partition in two chambers is then also arranged within this drum.
- the invention can also be realized on compaction devices with other types of compaction organs, such as sieve straps running over suction shoes with suction slits.
- the suction shoe 11 is separated in its interior by a partition 13 in two chambers 14.
- the two perforation tracks 12 of the compression strap 11 each run through one of the chambers 14.
- the chambers are connected via branch lines 15 and 16 to suction lines 17 and 18 which extend over a number of compression devices.
- the suction can be reduced or completely shut off, so that the perforation track 12 in question is subjected to suction or not at all, and accordingly has no or only a reduced compression effect on one of the drawn and to be compressed fiber slivers 19.
- the suction draft can be reduced by means of a blocking or throttle slide 20, which can be pushed partially or completely into the suction line 17 by means of a pushing device 21.
- the pushing device can consist of a cylinder / piston unit 22 which can be reversed via a control slide 23.
- the control slide has a zero position in which an reached position of the blocking or throttle slide 20 is maintained.
- the suction draft can also be reduced by means of other devices which are common and which can be used here in a sensible manner.
- the suction in a suction line can be reduced or even completely prevented by a bypass to be opened, through which the suction does not act on the perforation track 12.
- the suction channel 18 can also be provided with a device. hen, which also allows the suction in this suction channel to be interrupted or throttled.
- the suction train should be interrupted or rebuilt very quickly in order to achieve steep ramps and thus striking transitions between compressed and non-compressed sections of the fiber sliver.
- a blocking or throttle slide 20 in each of the stub lines 15, 16.
- the spur lines 15, 16 of a short section of spinning positions for example the spinning positions between two punches of the drafting system, to a branch suction channel and a blocking channel between the latter and the suction channel 17. or throttle slide.
- the second suction channel 18 would be unnecessary.
- the two fiber slivers are fed to a ring spinning device 24, in which they are rotated together in a conventional manner and wound onto a cop 27 by means of ring 25 and rotor 26.
- control slide 23 can be supplied with control signals via a control line 28 by the machine control or by a random generator, by means of which the control slide is actuated to actuate the blocking or throttle slide 20.
