Abstract
Official abstract text for this publication.
A reel body is the reel body in which an adhesive film having an adhesive layer on a base material layer is wound around a winding core. The adhesive film does not have a protective layer on the adhesive layer and is wound around the winding core in a state in which the adhesive layer and the base material layer are contiguous to each other in the radial direction of the winding core. A width of the winding core in an axial direction is smaller than a width of the adhesive film. In a rolled body of the adhesive film, an overhang portion jutting out in the axial direction of the winding core is provided.
First claim
Opening claim text (preview).
1 . A reel body obtainable by winding an adhesive film having an adhesive layer on a base material layer around a winding core, wherein the adhesive film does not have a protective layer on the adhesive layer and is wound around the winding core in a state in which the adhesive layer and the base material layer are contiguous to each other in a radial direction of the winding core, wherein a width of the winding core in an axial direction is smaller than a width of the adhesive film, and wherein a rolled body of the adhesive film is provided with an overhang portion jutting out in the axial direction of the winding core. 2 . The reel body according to claim 1 , wherein the overhang portion is provided on each of one side and the other side in the axial direction of the winding core. 3 . The reel body according to claim 1 , wherein the overhang portion is provided only on either of the one side and the other side in the axial direction. 4 . The reel body according to claim 1 , wherein on a side of an inner circumference of the overhang portion, an auxiliary core having the same diameter as the winding core and being freely attachable and detachable is disposed. 5 . The reel body according to claim 1 , wherein at an end face in the axial direction of the rolled body of the adhesive film, a guide plate for aligning an edge in a width direction of the adhesive film with the end face is disposed. 6 . A method for manufacturing a reel body, the method comprising winding an adhesive film having an adhesive layer on a base material layer around a winding core, Wherein, in the winding, the winding core having a smaller width in an axial direction than a width of the adhesive film is used, and the adhesive film having no protective layer on the adhesive layer is wound around the winding core while causing the adhesive layer and the base material layer to be contiguous to each other in a radial direction of the winding core, so as to form an overhang portion jutting out in the axial direction of the winding core in a rolled body of the adhesive film. 7 . A method for manufacturing an article, the method comprising a joining step of joining the adhesive film wound off from the reel body according to claim 1 to an adherend, wherein, in the joining, a side of an inner circumference of the overhang portion in the reel body is fixed to a winding core tool of a feeding apparatus, and at the same time, the adhesive film is wound off toward the adherend in a state in which an end face in the axial direction of the rolled body of the adhesive film in the overhang portion is brought into close contact with a guide plate of the feeding apparatus.
