METHOD AND APPARATUS FOR A TRANSFER TAPE APPLIED TO FORM A RAISED PROFILE

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.

A METHOD AND A MACHINE FOR WINDING A WEB ONTO SPOOLS TO FORM A SUCCESSION OF WEB REELS

A device and method of winding a web (W) of tissue paper or a non-woven material onto spools (2) to form a succession of web reels (3) on the spools (2) wherein the force in the winding nip (5) is measured and, as the diameter of the web reel (3) grows, the spool (2) on which the web reel (3) is wound is moved during winding along a horizontal plane such that, in the horizontal direction, the distance between the first supporting drum (4) and the spool (2) increases, and the second supporting drum (9) is moved vertically downwards to match the increasing size of the web reel (3) while maintaining contact with the web reel (3) to such an extent that a nip force between the web reel (3) and the second supporting drum (9) is maintained, and the first supporting drum (4) is moved vertically downwards as the diameter of the web reel (3) grows and moved to such an extent that the measured nip force in the winding nip (5) remains substantially at a set value or within the range of a predetermined upper and a predetermined lower value.

METHOD AND APPARATUS FOR PREPARING TRANSFER TAPE CONSTRUCTS FOR PAPER WEB TURN-UP PROCESSES

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.
