Method and apparatus for separating and spooling a paper web
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.
1. A paper web turn-up apparatus, the apparatus comprising:
a paper spool with a spool surface to attach a paper web;
a liquid adhesive bead dispenser positioned to deposit a liquid adhesive bead across the spool surface;
a paper cover formed separately and spaced apart from the paper web, the paper cover positioned to cover the deposited liquid adhesive bead, subsequently adhere to the advancing paper web, pull the advancing paper web to the paper spool, and sever the advancing paper web to complete a paper web turn-up; and
wherein the deposited liquid adhesive bead flows to a surface of the paper cover when the deposited liquid adhesive bead rotates with the paper spool and comes upon and adheres to the paper web in between a nip of the paper spool and a reel drum.
2. The apparatus of claim 1 wherein the paper cover comprises tissue paper.
3. The apparatus of claim 1 wherein the paper cover is attached to the paper spool with a pressure sensitive adhesive.
4. The apparatus of claim 1 wherein the paper cover inherently comprises pores; and wherein the liquid adhesive bead flows through the pores when the liquid adhesive bead is pressurized within the nip.
5. The apparatus of claim 1 , wherein the paper cover is punctured prior to its placement to give it perforations; and wherein the liquid adhesive bead flows through the perforations when the liquid adhesive bead is pressurized within the nip.
6. The apparatus of claim 1 wherein the paper cover comprises a paper with small perforations; and wherein the paper cover ruptures when the liquid adhesive bead is pressurized within the nip.
7. The apparatus of claim 1 , wherein the liquid adhesive bead is deposited in a line.
8. The apparatus of claim 1 , wherein the liquid adhesive bead is deposited at an angle relative to a rotary axis of the paper spool.
9. A method of performing a paper web turn-up, the method comprising:
depositing a liquid adhesive bead upon a spool surface of a paper spool;
coupling a paper cover comprising tissue paper formed separately and spaced apart from a paper web, to the spool surface of the paper spool;
covering the deposited liquid adhesive bead with the paper cover;
rotating the paper spool to press the liquid adhesive bead and the coupled paper cover between the paper spool and a reel drum in a nip of the paper spool and the reel drum;
flowing the liquid adhesive bead to a surface of the paper cover;
pressing the liquid adhesive bead and the coupled paper cover between the paper spool and the reel drum;
with the liquid adhesive bead upon the surface of the paper cover, adhering the advancing paper web to the paper spool; and
severing the paper web to complete the paper web turn-up.
10. The method of claim 9 additionally comprising the step of preassembling the paper cover with pressure sensitive adhesive strips on an edge of the paper spool and release coating strips on an opposite edge of the paper spool.
11. The method of claim 9 wherein the paper cover is attached to the paper spool with a pressure sensitive adhesive.
12. The method of claim 9 , wherein the paper cover inherently comprises pores, wherein the liquid adhesive bead flows through the pores when the liquid adhesive bead is pressurized within the nip.
13. The method of claim 9 , wherein the paper cover is punctured prior to its placement to give it perforations; and wherein the liquid adhesive bead flows through the perforations when the liquid adhesive bead is pressurized within the nip.
14. The method of claim 9 wherein the paper cover comprises a paper with small perforations; and wherein the paper cover ruptures when the liquid adhesive bead is pressurized within the nip.
15. The method of claim 9 , wherein the liquid adhesive bead is deposited in a line.
16. The method of claim 9 , wherein the liquid adhesive bead is deposited at an angle relative to a rotary axis of the paper spool.
