Abstract
A paper tape turn-up construct including a cover flap and a multi-bend structure to both protect an adhesive layer and to build an optimized elevated structure to present the adhesive layer during initiation of the paper web turn up process. Methods and apparatus to form the constructs and apply the constructs to paper production equipment are also included. The multi-bend paper turn up construct includes layers of adhesive and pulpable substrate with strategically located release materials, such as silicon that enhance a bridging of a gap between a rotating paper web and an empty spool surface.
Claims15
A method for performing a turn up process on a paper making machine, the 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;
- b. spinning the empty web spool and the transfer tape construct mounted on the empty web spool at a rotation speed sufficient to cause one or both of:
- aerodynamic forces and centrifugal forces to separate interfaces formed by the release coatings and adhesive;
- c. as a result of the aerodynamic forces and centrifugal forces acting on the transfer tape construct, separating a cover flap and an adhesive layer at a distal end of the transfer tape construct from a release coating;
- d. forming a peak with the pulpable substrate and the adhesive layer;
- e. with the peak comprising the pulpable substrate and the adhesive layer, bridging a gap between the empty web spool and a surface of a paper web rotating on a full web spool;
- f. adhering the adhesive layer to the paper web;
- and
- g. 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.
