Abstract
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.
Claims16
A method for performing a turn up process on a paper making machine, the turn up process comprising the steps of:
- a) mounting a cover flap transfer tape construct, comprising a cover flap over a tape construct and an adhesive layer on an underside of the cover flap, onto an empty web spool using an applicator package comprising a roll of prepared carrier paper and an adhesive that are dispensed from the applicator package to form the cover flap transfer tape construct, said adhesive layer is positioned over a release layer coated on a base of the cover flap transfer tape construct to facilitate the adhesive layer on the underside of the cover flap separating from the release layer during the turn up process;
- b) twisting the prepared carrier paper and the adhesive in the applicator package for mounting the cover flap transfer tape construct onto the empty web spool;
- c) spinning the empty web spool and the cover flap 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 act on the cover flap;
- d) as a result of the one or both of aerodynamic forces and centrifugal forces acting on the cover flap, separating the cover flap and the adhesive layer from the release layer to expose the adhesive layer;
- e) with the cover flap and the adhesive layer elevated off of the empty web spool due to the spinning of the empty web spool, bridging a gap between the empty web spool and a surface of a paper web;
- f) adhering the exposed adhesive layer to the paper web;
- and
- g) continuing to spin the empty web spool and the cover flap transfer tape construct until the paper web severs via separation of fibers included in the paper web.
