Paperband composites for transferring a paper web from a full web spool to an empty web spool. In some embodiments, the paperband composite 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 paperband composite allow for use during multiple turn-up procedures with one layer of paperband composite used per turn-up procedure. In some examples, the paperband composite 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 paperband composite may be spirally wrapped around the paper spool.

Methods and apparatus to form elevated profiles in mounted turn-up transfer tapes for paper processing. In some embodiments, the transfer tape may be a combination of a tape substrate coated on one side with a web grabbing adhesive and on the other side with a mounting adhesive and an affixed cord or cordlike feature, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer. In some embodiments an elevated profile, similar to that resulting from the incorporated cord or cordlike feature, may be formed during the application of the transfer tape with specialized apparatus.

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.

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.

A method and apparatus for the production of coreless paper rolls, including a winding phase on a central spindle of a paper web carried out by a main reel, until the formation of a wound paper roll, a phase of extraction from the wound roll of the spindle by application of a relative axial extraction force between the roll and the spindle, where the winding phase includes a first winding phase of a number of web revolutions on the central spindle performed at a first winding tension that is lower than the next winding tension.

A family of paper tape turn-up constructs for accomplishing automated paper web turnup in paper processing. Methods and apparatus to form the constructs are described. Methods and Apparatus to apply the constructs to paper production equipment are also described. In some examples, the paper tape turn-up construct includes a cover flap to protect an adhesive layer during initiation of the paper web turn up process.

The disclosed subject matter provides a mandrel feeding device and a battery winder. The mandrel feeding device has a dispensing station, an adjusting station, an adhesive application station, a transferring unit, a dispensing unit, a feeding unit configured for gripping a mandrel on the transferring unit and transferring gripped mandrel to a winding mechanism.

A cover-flap transfer tape construct and associated applicators for paper web turn-up are disclosed. A zone-coated substrate carried on a linered web includes a top-side central web-grabbing adhesive band bounded by uncoated edge zones, and underside edge mounting adhesive bands separated by an uncoated middle zone. An applicator forms an out-of-plane raised profile across a central portion of the tape while maintaining planar side bands, using cooperating forming members (convex crest and complementary cavity) and manual or motorized feed. The formed length is cut to yield a discrete tape construct with the raised profile over the central adhesive and side bands aligned with mounting adhesives. The tape construct promotes reliable interception and transfer of a moving paper web during turn-up.
