Abstract
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.
Claims9
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,
- wherein a rolled body of the adhesive film is provided with an overhang portion jutting out in the axial direction of the winding core,
- wherein on a side of an inner circumference of the overhang portion, an auxiliary core which is freely attachable and detachable, is disposed,
- wherein the auxiliary core has the same diameter as a diameter of the winding core in terms of overall width of the auxiliary core, and
- wherein one end surface of the auxiliary core in the axial direction comes into contact with one end surface of the winding core in the axial direction.
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,
- wherein on a side of an inner circumference of the overhang portion, an auxiliary core which is freely attachable and detachable, is disposed,
- wherein the auxiliary core has the same diameter as a diameter of the winding core in terms of overall width of the auxiliary core, and
- wherein one end surface of the auxiliary core in the axial direction comes into contact with one end surface of the winding core in the axial direction.
