Zusammenfassung: | PROBLEM TO BE SOLVED: To prevent a warp of a paper roll front end part in paper splicing by sticking auxiliary tabs in both sides of the front end part of the paper roll cut into a V-shape substantially in a paper splicing preprocessing device carrying out preprocessing in the paper roll for paper splicing. SOLUTION: This paper splicing preprocessing device for the paper roll P is provided with a paper roll supporting device 1 supporting the paper roll P freely rotationally in the normal/reverse direction, a table 3 supporting a fed out part in the paper roll P, a pair of main processing apparatuses 6 arranged opposedly to each other in the both side upper positions of the table 3 and each having a cutter device 4 cutting the fed out part in the paper roll P on the table 3 into a V-shape substantially and an adhesive layer forming device 5 forming a paper splicing adhesive layer 23a in the front end part of the cut paper roll P, and a tab sticking device 8 sticking a tab T' in the top part of the substantially V-shaped front end part in the paper roll P. An auxiliary tab sticking device 9 projectingly sticking a plurality of auxiliary tabs T having adhesive layers Tc to both sides in the front end part of the paper roll P cut into the V-shaped approximately is arranged above each of the both sides of the table 3. |
