Abstract

A glass film transfer apparatus includes a wind-off section that winds off the glass film from a roll around which the glass film is wound, a long interleaf being laminated on the glass film; a glass film transfer section that transfers the glass film which is wound off from the wind-off section and is separated from the interleaf; a take-up section that takes up the glass film transferred by the glass film transfer section in the form of roll, while laminating the long interleaf on the glass film; and an interleaf transfer section that carries out the interleaf separated from the glass film which is wound off from the wind-off section, and carries in the interleaf toward the take-up section. Furthermore, the glass film transfer apparatus includes a take-up adjusting mechanism that adjusts a take-up state of the interleaf and the glass film in the take-up section.

First claim

The invention claimed is:

1. A glass film transfer apparatus that continuously transfers a long glass film, comprising:
a roll-containing wind-off section that winds off the glass film from a supply roll around which the glass film having a long interleaf laminated on the glass film is wound;
a roller-containing glass film transfer section that transfers the glass film which is wound off from the wind-off section and is separated from the interleaf;
a roll-containing take-up section having a take-up roll that takes up the glass film transferred by the glass film transfer section, while laminating the interleaf on the glass film;
a roller-containing interleaf transfer section that carries out the interleaf separated from the glass film which is wound off from the wind-off section, and carries in the interleaf toward the take-up roll in the take-up section; and
a roller position of one or more rollers carrying the interleaf or the glass film is changeable such that take-up positions of the interleaf and the glass film on the take-up roll are at different angular positions on the take-up roll,
wherein the take-up roller in the take-up section comprises a lamination roller that laminates the glass film transferred by the glass transfer section on the interleaf transferred by the interleaf transfer section, and
the glass film is laminated on the interleaf in a rotation range in which a first rotation angle of the lamination roller after contact of the interleaf with the lamination roller is 45° or more, and the interleaf having the glass film laminated thereon keeps contact with the lamination roller and is detached from the lamination roller after being transferred in a rotation range in which a second rotation angle of the lamination roller after the lamination is 30° or more and 90° or less, the sum of the first rotation angle and the second rotation angle being 270° or less.

2. The glass film transfer apparatus according to claim 1 ,
wherein the interleaf transfer section has a dancer roller mechanism that comes into contact with the interleaf being transferred by the interleaf transfer section along a width direction of the interleaf to thereby apply tension to the interleaf, and that adjusts a path length of a transfer path of the interleaf in the interleaf transfer section.

3. The glass film transfer apparatus according to claim 2 ,
wherein the dancer roller mechanism has a first roller and a second roller that come into contact with the interleaf in a state where the first and second rollers are parallel to each other to thereby apply tension to the interleaf, the first roller being disposed at a position in which the first roller can come into contact with one side of the interleaf, and the second roller being disposed at a position in which the second roller can come into contact with the other side of the interleaf, and
the first roller and the second roller are movable in a direction of coming into contact with the interleaf.

4. The glass film transfer apparatus according to claim 2 ,
wherein the interleaf transfer section includes at least one roller having a contact surface that comes into contact with the interleaf, and the contact surface has viscosity.

5. The glass film transfer apparatus according to claim 1 , wherein:
the roller-containing glass film transfer section and the roller-containing interleaf transfer section are separately stored in two regions independent from each other, and
each of the two regions is independently exhausted.

6. The glass film transfer apparatus according to claim 5 , further comprising a partition wall dividing the glass film transfer apparatus.
