  • the turntable mouth is positioned stopped with respect to the longitudinal axis of the flat can. The Positions can be selected. It is therefore possible to determine at which position the loop end in the mouth of the turntable (belt guide channel) leads.
  • the positioning of a sliver is achieved in cooperation a drafting device and a displacement means.
  • the A method for positioning a sliver end is characterized in that that in the standstill position of the flat can by a drafting device a drafting point in the sliver between Calender roller pair and belt guide channel is formed and by then moving the flat jug using a moving device the sliver from the standstill position to a transfer position separated at the default point and the separated sliver end is pulled out of the tape guide channel so that it with constant Length positioned at the edge of the end wall of the flat can is.
  • a default point is formed by the default device at a distance of at least one stack length Pair of calender rollers by clamping the sliver one nip is formed and this nip by the drafting device is moved transversely to the conveying direction of the sliver until there is a delay. It is between the nip and the pair of calender rolls formed a default. Then through that Distortion device released the clamping of the sliver.
  • the default point could also be formed if the default device is guided in the direction of the tape guide channel.
  • the delay device can a portable clamping device or a portable mechanical lever or stop.

  • the turntable 7 rotates, so that the sliver in an underlying 9 via its mouth Flat can 14 is stored.
  • the flat can 14 has a rectangular base. Is in the empty state a movable can plate below or at the level of the upper one Can edge. With increasing filling of the jug, the jug plate becomes against the force of an underlying spring moved towards the bottom of the jug.
  • the flat can 14 has narrow end walls, the LSW end wall and the end wall RSW.
  • the flat can is on a traversing device 160.
  • the traversing device 160 has one not shown here Drive with control device.
  • the flat can 14 below the turntable between the the two reversal points A and B of their traversing path AB. The flat can thus moves between the two shown Positions of the flat can 14 and the flat can 14 '(dashed).
  • the sliver becomes cycloidal on the can plate the flat can.
  • the filing is done by a End wall of the flat can to the other end wall and vice versa.
  • a storage path forms from one end wall to the other one layer of sliver each.
  • a filled flat jug has a variety of such locations.
  • the traversing speed the flat can 14 is on the delivery speed of the turntable 7 matched. Starting, operation and braking the turntable and the flat jug are synchronized. If the measuring organ 17 to measure the delivered tape length It registers the limit of the delivered sliver length at the same time a signal to the machine control system 13.
  • the machine control system 13 causes opposite the drives for the turntable 7 and the traversing device 160 that this to a defined Time be stopped.
  • This shutdown is such that the flat can 14 at a standstill a position in the vicinity or in the reversal point B reached, i.e. the front wall RSW is nearby or in reversal point B and the front wall LSW is in the area below the turntable 7.
  • the flat can 14 is thus located in the standstill position SP on the traversing path AB.
  • This The standstill position SP could be varied somewhat by being in the vicinity the reversal point is stopped. This can affect the length of the future tape end will be taken.
  • Figure 2 shows schematically the assignment of the turntable 7 from a Top view of the flat can.
  • the flat can 14 is in the standstill position SP on the traversing path AB.
  • the turntable 7 is located above the flat can 14.
  • the position of the Turntable 7 to the standstill position SP of the flat can 14 positioned, i.e. the turntable 7 is always so, for example stopped that the mouth 9 of the tape guide channel 8 always in the same position comes to a standstill.
  • the position of the mouth 9 is advantageously set so that the sliver 11 is held vertically in the longitudinal axis LA of the flat can. This corresponds to position 90 of the mouth 9.
  • a second possibility results when the turntable is rotated by 180 ° with its mouth 9 'reaches position 90'.
  • FIG. 3 shows that the flat can 14 in the standstill position SP is stopped.

  • the sliver end E is attached the end wall LSW of the flat can 14 down. Since the turntable 7 for example, positioned with its mouth 9 in the longitudinal axis LA the sliver end E comes in the middle of the Front wall LSW for storage (Fig. 3c).
  • Figures 4 to 4d show the formation of a draft in the sliver with a drafting device.
  • Figure 4 shows a schematic Top view of the initial position of the drafting device, i.e. the work clamp arm 20, stop 22 and their actuators 21 and 23. Furthermore, it is shown schematically the inlet opening 10 of the tape guide channel 8 by the Sliver 11 is located. There is a stop next to the inlet opening 10 22 arranged. This stop is held mechanically and guided by an actuator 23. This actuator has a drive, not shown, and its control as well as a sliding mechanism. Opposite the stop 22 is a clamp arm 20, also outside the entry opening 10 arranged. This clamping arm 20 is held mechanically and guided by the actuator 21.
  • This actuator 21 also has a drive and not shown its control and a sliding mechanism.
  • the clamp arm 20 is, for example, transverse to the adjusting device 21 Conveying direction of the sliver 11 moves.
  • the clamping arm 20 steers the sliver 11 and clamps it with the stop 22nd stop 22 and clamping arm 20 form a clamping point KS.
  • the KS clamping point will continue the previous movement of the clamping arm 20th moved further across.
  • This shifting of the clamping point shows the comparison between Figure 4a and 4b.
  • the shift of the Clamping point KS takes place until the sliver warps entry.
  • Figure 4c shows this default. For better illustration there was a change to the side view.
  • the default VS occurs between the nip KS and the pair of calender rolls 6, 6 '. Depending on the material to be processed this displacement path is determined and by controlling the Actuators 21 and 23 set. With delay reached and the creation of a default point, the KS terminal point is opened, i.e. the clamping arm 20 is returned to its starting position. The next step in positioning a belt now takes place shown in Figure 3 to 3c shifting Flat can 14 to takeover position C, for example, by use the traversing device 160. By moving the Flat can, the sliver with the draft point is exactly in Conveying direction of the belt, i.e. positioned in the tape guide channel and exactly separated at the default point.
