Abstract
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.
Claims20
A method for performing a turn up process on a paper making machine, the turn up process comprising the steps of:
- a. mounting a proximal end of a transfer tape construct at a first position on an empty web spool, the transfer tape construct comprising folded layers of:
- adhesive, release coating, and pulpable substrate, wherein the pulpable substrate comprises a raised profile portion forming a peak with the pulpable substrate and a layer of adhesive;
- b. with the peak comprising the pulpable substrate and the layer of adhesive, bridging a gap between the empty web spool and a surface of a paper web rotating on a full web spool by lifting the raised profile portion of the transfer tape construct as a spool rotational speed of the empty web spool increases a centrifugal force on the raised profile portion of the transfer tape construct mounted on the empty web spool;
- c. adhering the layer of adhesive to the paper web;
- and
- d. continuing to spin the empty web spool and the transfer tape construct until the paper web severs via separation of fibers included in the paper web.
