Problems solved by technology

[0016] However, in this case, the tension acting on the sheet 100 at the time of winding is locally concentrated on the part in the center of the width direction of the sheet 100 where the junction with the sheet-like connecting body 103 (the area where the adhesive tape 101 is pasted) is formed. Therefore, there will be a problem that wrinkles 102 are likely to be formed around the junction in the end of the sheet 100.

Embodiment Construction

[0046] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0047] figure 1 It is a perspective view which shows the sheet roll body which concerns on 1st Embodiment of this invention. The wound sheet 1 is extended by connecting the ends of a plurality of elongated glass films g to each other, and winds the connected plurality of glass films g on the outer peripheral surface of a core 2 in a roll shape. It should be noted that, here, the glass film g is a glass with a thickness of 300 μm or less, for example, formed by a down-draw method such as an overflow down-draw method, for example, it is used in flat panel displays such as liquid crystal displays or organic EL displays, organic EL lighting, Solar cells etc.

[0048] Ends of two adjacent glass films g in the winding direction are connected by a sheet-shaped connecting body 3 . The sheet-shaped connecting body 3 is formed of a resin film such as a polyethylene terephthal...

Abstract

A sheet roll (1) is manufactured by placing a sheet-like coupling member (3) on end portions of a plurality of glass films (g) so as to span therebetween, coupling the end portions of the glass films (g) together, and rolling the coupled plurality of glass films (g). The sheet-like coupling member (3) used in the sheet roll (1) includes wide width portions (4) for forming wide joint portions joined to the glass films (g) at each of both end portions thereof in a rolling direction, and a necked portion (5), which is narrower than the wide width portions (4) and is formed at a middle portion thereof in the rolling direction.

Description

technical field [0001] The present invention relates to improvements in a sheet winding body in which a plurality of sheets are connected and wound into a roll, and a connection structure in which ends of a plurality of sheets included in the sheet winding body are connected to each other. Background technique [0002] As is well known, a continuously produced elongated sheet of resin film or paper is usually wound around a core in a roll shape and housed. In addition, in the sheet winding body containing the sheets in this way, when the sheet wound on the winding core does not meet the predetermined length, the method of winding the sheet before the entire length of the sheet reaches the predetermined length may be adopted. The end portion of the sheet wound on the core is connected to the start end portion of the other sheet while being wound on the core (for example, refer to Patent Document 1). [0003] In addition, in recent years, glass films that have been thinned to...
