An apparatus for dispensing an adhesive with paper covers to be used in a paper web turn-up operation. The resulting adhesive and paper cover construct is used in effecting the attachment of a paper web to an approaching spool. In some examples, the paper cover of the deposited adhesive may be affixed on two sides surrounding the deposited adhesive, in other examples a single attachment may be used. In some examples, the paper cover may be perforated to facilitate rupture of the paper and flow of adhesive. In some examples, perforations may enable the movement of adhesive through the paper.

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.

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.

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.
