Apparatus for winding at least one strip of material for the production of electrical energy storage devices, comprising: a rotatable winding core, configured to grip the strip and actuatable to carry it in rotation and thus form a winding; a feed unit to feed the strip of material; and a handling device configured to move the winding core at least between a winding station, at which the winding core is configured to receive the strip in feeding, grip it and wind it about the rotation axis, and a second station; wherein the handling device is configured to move the winding core from the winding station to the second station during the winding.

A web transfer system includes a first winder with a first core thereon and a second winder with a second core thereon. The web transfer system includes a roll changer carriage that is moveably mounted on a track and communicates with a carriage actuator. A linkage is pivotally mounted to the roll changer carriage and is movable between a first and second roll transfer positions. The linkage includes a lay-on roll and an auxiliary arm. The auxiliary arm is pivotable between a retracted and extended position. The auxiliary idler is rotatably mounted to the auxiliary arm. The lay-on roll and the auxiliary idler roll transfer a web from the first core to the second core.

The present invention relates to a paper web processing apparatus featuring a transfer tape construct designed for efficient turn-up operations. The apparatus includes a carrier paper with a zone coating applied in longitudinal stripes, an adhesive layer laminated to the carrier paper, and a cover flap that protects the adhesive from environmental contaminants. The transfer tape construct is mounted on an empty web spool, and the zone coating comprises a silicone-based release material. The cover flap is engineered to open in response to centrifugal and aerodynamic forces during spool rotation, facilitating the separation of the adhesive layer into ribbons along the zone-coated areas. This configuration allows the cover flap to bridge a gap between the empty web spool and a paper web, ensuring a seamless transfer process. The apparatus is designed to enhance the reliability and efficiency of paper web processing, particularly in high-speed environments.

A rewinding system includes a rewinding apparatus for winding a manufactured thin-film tape on a re-winding roll; a loading apparatus for loading the re-winding roll on which the thin-film tape is rewound; and a cutting apparatus for cutting the thin-film tape. The rewinding apparatus includes first and second mounting members in which re-winding rolls are inserted; and a connecting member connected to an end of each of the first and second mounting members to move the first and second mounting members. The first mounting member rotates around a shaft thereof, the second mounting member rotates around a shaft thereof, and the connecting member rotates the first and second mounting members to change positions of the first and second mounting members, and moves at least one of the first and second mounting members to the place where the loading apparatus is arranged.

Methods and apparatus to form tear-off composite adhesive sheets that adhesively attach a paper web to an empty web spool. In some embodiments, the composite adhesive sheet is applied in several layers to an empty web spool, each layer suitable for fixedly attaching a paper web to the empty spool. Multiple layers of composite adhesive sheet allow for use during multiple turn-up procedures with one layer of composite adhesive sheet used per turn-up procedure. In some examples, the composite adhesive sheet may be applied to a paper spool tangentially along the spool face and perpendicular to the axis of rotation of the spool. In other examples, the composite adhesive sheet may be spirally wrapped around the paper spool.
