A roll sheet with a continuous sheet wound in a roll form is rotated in a forward direction to supply the sheet to a printing unit. A sensor whose output is changed in accordance with a distance between the sensor and the sheet is used. A rotation direction of the roll sheet is switched from an opposite direction to the forward direction on the basis of the output of the sensor during rotation of the roll sheet in the opposite direction.

A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: arranging a first winding support with a first elongated element of a first type wound on the first winding support; arranging a second winding support with a second elongated element of a second type different from the elongated element of the first type wound on the second winding support; arranging a coupling device including a first coupling body and a second coupling body rotatable with respect to one another about a rotation axis; and arranging the first winding support on the first coupling body and the second winding support on the second coupling body.

The invention relates to a method for a multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region and for which a normal length is predefined which is dependent on the respective application, in which material webs are removed from at least two material stores which are each associated with one or more tracks; and in which the material consumption of at least one material store is impacted during operation, in particular in dependence on residual quantities in the material stores, in that the length of the interleaved sheets is varied in the respective track or tracks with respect to the normal length at least for this material store.

A roll sheet with a continuous sheet wound in a roll form is rotated in a forward direction to supply the sheet to a printing unit. A sensor whose output is changed in accordance with a distance between the sensor and the sheet is used. A rotation direction of the roll sheet is switched from an opposite direction to the forward direction on the basis of the output of the sensor during rotation of the roll sheet in the opposite direction.

A material strip collection mechanism coiling fed material strip on a reel includes a vertically positioned reel bracket rotatable about a vertical axis between a first configuration and a second configuration. The mechanism further includes a first arm holding the reel and a second arm each rotatable to drive the reel and coil the material strip on the reel. With the reel bracket in the first configuration, the first arm is in a material strip collection position to allow the material strip to be coiled on each empty reel held by the first arm to form a full reel, while the second arm is in a standby position to allow the full reel held by the second arm to be replaced with a new empty reel.
