  • the trigger element is one of two take-off disks of the trigger device.
  • the two pulleys form, for example, a common nip or a thin gap, wherein the fiber web coming from the drafting device passes between the two take-off rolls as they pass through the take-off device and is guided and actively pulled away from them and possibly still being warped.
  • the pulleys are in turn preferably oriented such that their axes of rotation parallel to the axis of rotation of at least one of the pulleys in connection standing (single) drive.
  • Nonwoven fabric is arranged, wherein the withdrawal element is formed as part of the compressor.
  • the compressor which may be a nonwoven funnel to be passed from the nonwoven fabric, causes the nonwoven fabric to be compressed laterally, thereby compacting it.
  • band adhesion tensile strength
  • the or the trigger elements form a part of the compressor.
  • the nonwoven fabric also passes into contact with at least one withdrawal element when passing through the compressor.
  • the discharge element (s) are placed with respect to the compressor in such a way that the surface of the respective withdrawal element can move in the transport direction of the fiber fleece in the area of the output of the compressor to be traversed by the fiber fleece.
  • the outwardly projecting fiber ends of the nonwoven fabric can be guided in this case by the withdrawal elements and actively applied to the remaining nonwoven fabric, so that the passage through the compressor can be positively influenced.
  • the trigger element is designed as a take-off disk
  • the trigger device comprises a further take-off disk in addition to the take-off disk
  • the two take-off disks form a common gap which forms a passage opening of the compressor.
  • the fiber fleece comes in this case, not or only conditionally with an output wall of the compressor in contact. Rather, the pulleys form the actual output of the compressor, so that the pulleys and the compressor to a certain extent form a structural unit of the spinning preparation machine.
  • the passage opening forms a, downstream in the transport direction of an input, output of the compressor.
  • the nonwoven fabric passes into the compressor via a funnel-shaped inlet, where it is folded and compacted, for example, and then captured by the haul-off wheels and finally pulled out of the compressor.
  • the pulleys or their axes of rotation are aligned in such a way that they come laterally in a plan view of the drafting with the nonwoven fabric in contact.
  • the two take-off disks each have a region facing away from the respective adjacent take-off disk and facing away from the adjacent take-off disk, wherein the regions facing away from the respective adjacent take-off disk each transition into a surface section of the compressor.
  • the mutually facing portions of the pulleys can form the output or output gap of the compressor, it is conceivable that the portions which are remote from the respective opposite pulley, directly adjacent to a corresponding surface portion of the compressor.
  • a certain, albeit smaller, gap should be present between the operating surface of the respective pulley and the compressor in order to avoid grinding between the pulley and the compressor surface.
  • the exhaust disks form a bottom region and / or a side wall region of the compressor, wherein the compressor is preferably designed to be funnel-shaped and at least partially.
  • the compressor can thus have a tapered in the transport direction inwardly facing surface, partially are formed by corresponding surface portions of the or the pulleys.
  • the surface of the compressor which comes into contact with the fiber fleece is always immovable, according to the present invention it is possible to make individual surface sections movable by being realized by surface sections of the pulleys.
  • the spinning preparation machine has a sensor in the region downstream of the drafting device in the transport direction for determining the speed of a nonwoven fabric passing through said region during operation of the spinning preparation machine.
  • the measurement can be done, for example, by means of mechanical elements, the z. B. can also be in contact with the nonwoven fabric done.
  • contactless sensors are preferably used, which determine the speed, for example, by optical methods.
  • the advantage in a corresponding speed determination lies in the fact that the actual tensioning delay can be checked and adjusted if necessary.
  • the spinning preparation machine comprises a control unit which is designed to change the rotational speed of the drive in response to signals from the sensor, so that finally said adjustment of the tensioning delay can take place. If the determined speed is lower than a setpoint stored in the control unit, then the speed of the drive should be increased in order to increase the mentioned tensioning delay. Conversely, a throttling of the speed should take place when it is determined by means of the sensor that the speed of the fiber web and thus also the tensioning distortion are too high.
  • FIG. 1 shows in a side view schematically and as an example of a spinning preparation machine 1 according to the invention a stretch for stretching (uniform) of a strand-like fiber composite 3.
  • a stretch for stretching (uniform) of a strand-like fiber composite 3 3.

  • a trigger assembly of a or several so-called sliver cans 17 and taken over corresponding deflections 16 the respective drafting 2 of the route (or in the case of a multi-head section: the drafting 2 of the route) supplied.
  • the drafting system 2 usually consists of three or more pairs of rollers, each of which may comprise at least one lower roller and one upper roller.
  • the desired distortion of the fiber composite 3 finally arises in that the individual lower rollers and thus also the individual, in contact with these, upper rollers in the illustrated transport direction T of the fiber structure 3 have an increasingly higher peripheral speed.
  • a compressor 10 which is preferably designed as a fleece funnel and causes a compression of the fiber fleece 15.
  • the nonwoven fabric 15 reaches the area of a take-off device 5 which generally comprises a plurality of rotatable or at least partially driven take-off elements 8, for example in the form of two take-off disks 9 contacting the nonwoven fabric 15 from two sides.
  • the nonwoven fabric 15 generally arrives in the region of a rotating turntable 18 and is deposited by this loop into a provided spinning can 17.
  • FIG. 1 in synopsis with FIG. 2 results (which shows a possible drive concept of a known route), it is customary in the art, the axes of rotation 6 of the individual drafting rollers 4 and the axes of rotation 6 of the trigger elements 8 to align parallel to the individual components without deflections using a central, or as in FIG. 2 shown to be able to drive two separate drives 7, wherein the drive axes are also parallel to said axes of rotation 6.
  • FIG. 3 shows only a principle possible mutual arrangement of the individual components, the circular representation of the pulleys 9 and the single drive of the same need not mean that their axes of rotation 6 must necessarily be aligned vertically; rather, that is in the FIG. 3 preferred orientation shown).
  • FIG. 3 Another advantage of the proposed single drive also shows FIG. 3 , Since the single drive allows separate speed control of the trigger elements 8, by adjusting the corresponding drive speed of the single drive and the Anspannverzug the spinning preparation machine 1 before, during or after the stretching operation can be changed (under the Anspannverzug is the ratio of the peripheral speeds of the pulleys 9 and the Ab pulleys immediately upstream drafting roller 4, ie the drafting roller 4, which is placed in the region of the drafting system exit to understand).

  • FIG. 5 finally different from FIG. 4 in that the driven take-off roll is not connected directly but via a belt 22 to the associated drive 7.
  • FIG. 6 a generally known from the prior art fleece funnel, as used for example as a compressor 10 can come.
  • the fleece funnel has an opening serving as an inlet 20 and a through opening 19 which serves to densify the fibrous web 15 and which can simultaneously serve as the exit 21 for the fibrous web 15.
  • the two take-off disks 9 can be part of the compressor 10, which is preferably present as a fleece funnel.
  • the bottom area 14 and / or the side wall areas 13 have corresponding recesses into which the individual take-off disks 9 can protrude and thus form part of the inner surface of the compressor 10.
