Abstract:
1. A sheet sticking apparatus, comprising: a sheet feed-out unit for feeding out a sheet to a position facing a surface of a plate-shaped object; and a press roller for imparting a press force to said sheet to stick the sheet from one end toward the other end of the plate-shaped object, wherein said sheet feed-out unit is provided with a tension measuring means for measuring a tension of the sheet between said sheet feed-out unit and said press roller, and a sticking angle maintaining means including a feed-out head movable in such a direction that a sticking angle of the sheet is constantly maintained with respect to said plate-shaped object, wherein said tension measuring means measures the tension immediately before sticking the sheet to the plate-shaped object by means of said press roller, and the feed-out head of said sticking angle maintaining means moves in proportion to a relative movement amount of the press roller with respect to said plate-shaped object to maintain the sticking angle substantially constant, thus the tension of the sheet is maintained at a substantially constant level.
