Problems solved by technology
Although the belt can be guided laterally into an absolutely stable position, this design is very complex and expensive to manufacture, especially when the belt also requires specialized manufacturing processes
Furthermore, this does not solve the problem that if the belt partially lifts off the diverting guide rollers in a slack state, the belt may move sideways, thereby causing a positive connection between the configuration of the belt and the configuration of the diverting guide rollers release
However, this device is only effective during winding and does not solve the described problems during belt starting

Embodiment Construction
[0025] The control unit ST is connected via a path 24 to a valve 26 with which the connection from the pump 28 to the cylinder Z1 is made or broken accordingly. The cylinder Z1 acts on the end of a first mounting point (not shown) of the shaft 30 on which the roller R5 is mounted. The second mounting point (not shown) of the shaft 30, which allows the rotational movement of the shaft 30 and thus the roller R5 (which is produced by the movement of the mounting part 31 via the cylinder Z1), is arranged on the opposite side to the first mounting point . A detailed diagram and functional description of such a device can be found, for example, in the exemplary embodiment of EP-1675976. Due to the skewing of the shaft 30 from its initial zero position (in a plane extending almost parallel to the plane of the strip entrance), the position of the entry line of the strip R on the roller R5 changes with respect to the previous strip transport direction and thus also the strip transport...

The invention relates to a device for producing laps, comprising: a rotating continuous belt (R), which is tensioned by means of a tensioning device (3) and wound around several deflection guide rollers (R1-R6) The core (H) is guided to form the loop (S) of the lap (WW), wherein the core is held in two windings protruding radially beyond the core and mounted in a frame (MS) Between the discs ( W1 , W2 ) and at least one of the turning guide rollers ( R2 ) is movably mounted transversely to its axis of rotation by means of a pivoting device ( 8 ) for dispensing finished laps. In order to prevent the strip edge (Rs) of the strip (R) from running to the side winding discs (W1, W2) when starting a new winding process, it is proposed to provide additional means (15, 16; 18, 19; 21, 22; 31, 32; 38, 39; 44, 45; 51, 52), viewed transversely to the longitudinal direction of the strip, in the relaxed state of the strip, the additional means hold the strip (R) in a position, or before the retensioning of the belt, returns the belt to the position it had previously occupied in the tensioned state during the winding process on said turning guide rollers (R1-R6).
Description
technical field [0001] The invention relates to a device for producing laps. Background technique [0002] Devices of this type have been described, for example, in EP-799337A1, in which a rotating belt is used to form the lap. [0003] If the belt gradually deviates towards the side and perpendicular to its direction of motion during winding and the edge of the belt comes into contact with the lateral cotton reel, problems can occur, which have been identified and described in the other publication EP-878568A2 . On the one hand, this can damage the belt edge, and on the other hand, edge fibers can be pulled out of the lap sheet to be wound, which in turn leads to a qualitatively unclean lap. In order to solve these problems and to guide the belt into a stable position relative to the coil, it is proposed here that the belt is provided with a one-sided configuration which cooperates with the configuration surface of the deflection guide rollers and forms a positive connec...
