- the invention now has the task of carrying out the To further develop EP-846 795 and to propose a device for band separation, which is a simple and safe tape separation without damaging the Strap structure of the strap loops lying on top of the jug allows for a short time.
- This device makes it possible to feed the sliver through the toothed partition immediately record in that position and separate it safely and quickly.
- the partition plate during the separation process is held against the underside of the turret plate by means of spring elements. This ensures safe and exact guidance of the tooth tips for complete detection the fibers of the sliver on the underside of the turret plate guaranteed.
- the divider off-center between the two clamping edges arrange ensures that between the two clamping edges only a sliver separation takes place at the point where the divider in a smaller distance from the clamping edge is arranged.
- the pressure angle ⁇ Reduce the front tooth flank of the teeth down to the tooth base.
- the partition plate be made via guide means in this way is guided so that the tooth tips of the partition plate during its displacement be moved from a rest position towards the bottom of the turret plate.
- the guide means at least a guide pin fixed to the swivel arm is formed, which in at least engages a link guide of the divider.
- guide pin is to be understood generally and not only on a cylindrical one Pin aligned. Other cross-sectional shapes and designs of the guide pin are also to be understood by this.

- a method for carrying out the separating process is also proposed, with the start of the changing process of the full can against an empty can which is on standby then taking place at a reduced rotational speed of the funnel wheel when the outlet opening of the funnel wheel has reached a certain position.
- This position is sensed using suitable sensors.
- the aim of this is to ensure that as little fiber material as possible is deposited in the free space between the filled can and the following empty can during the changing process while the sliver supply is running and throttled. This makes it possible for the separation device to have the smallest possible sliver loop for reliable detection for the separation process.
- the suitable position of the outlet opening of the funnel wheel for starting the changing process depends on the reduced speed of the funnel wheel and the changing speed of the can changer and must be adjusted accordingly.
- the partition plate being moved back and forth at least once after the separation process has been completed and during the downward movement of the separation device. This movement ensures that the separated strip ends, which under certain circumstances can still clamp in the area between the clamping edge and the separating plate on the separating device, are safely released and released by the separating device. This prevents sliver loops from being pulled down from the can when the separating arm moves downward due to the clamped sliver end. However, this event occurs relatively rarely.

Description
Des weiteren wird ein Verfahren vorgeschlagen, wobei nach vollendetem Trennvorgang und während der Abwärtsbewegung der Trenneinrichtung das Trennblech wenigstens einmal hin und her bewegt wird. Diese Bewegung gewährleistet, dass die getrennten Bandenden, welche unter bestimmten Umständen noch im Bereich zwischen Klemmkante und Trennblech an der Trenneinrichtung festklemmen können, sicher von der Trenneinrichtung gelöst und freigegeben werden. Damit wird verhindert, dass durch das festgeklemmte Faserbandende Faserbandschlaufen bei der Abwärtsbewegung des Trennarmes von der Kanne heruntergezogen werden. Dieses Ereignis kommt jedoch relativ selten vor.
