Stepped scar reduction structure of the roll-like material, manufacturing method of the step marks reduction structure of the roll-like material and the roll-like material

摘要

PROBLEM TO BE SOLVED: To provide a step mark-reducing structure of a roll-like article, which can almost completely prevent the occurrence of step marks and allows the roll-like article to be easily produced; to provide a method for producing a roll-like article, which hardly causes step marks on a belt-like article wound around a core and allows the roll-like article to be easily produced; and to provide a roll-like article.;SOLUTION: When a winding-starting end part 3 of a single-sided adhesive tape 2 is stuck and fixed on an outer peripheral surface 1a of a core 1, at the winding-starting end part 3, a step 10 corresponding to the thickness of the tape is formed between an outer peripheral surface 2a of the single-sided adhesive tape 2 and the outer peripheral surface 1a of the core 1. When a liquid or paste-like curable resin is disposed so as to fill a space having an approximately triangular cross section formed between an end surface 2b of the winding-starting end part 3 and the outer peripheral surface 1a of the core 1 and is cured, a step-lessening member 5 including any one of a photocurable resin and a hot-melt resin is formed, thereby lessening the step 10. The single-sided adhesive tape 2 is wound around the core 1 having the step-lessening member 5 disposed thereon in a plurality of wound layers, thereby producing a roll-like article.;COPYRIGHT: (C)2014,JPO&INPIT
