Claims8
A conveyance method for conveying a glass film in a predetermined direction by applying a conveying force to the glass film while supporting the glass film through use of free rollers,
- the conveyance method comprising:
- applying flows of a fluid to the free rollers to apply a rotation auxiliary force to the free rollers in a rotation direction of the free rollers during conveyance of the glass film,
- wherein one longitudinal end of the glass film has a resin sheet coupled thereto, and
- wherein the applying of the flows of the fluid comprises starting the flows of the fluid to each of the free rollers when the resin sheet reaches a top of that free roller such that when the one longitudinal end of the glass film reaches the top of each of the free rollers, the free rollers are receiving the rotation auxiliary force.
A conveyance apparatus for conveying a glass film, the conveyance apparatus comprising:
- a conveying force applying unit configured to apply a conveying force to the glass film;
- free rollers configured to support the glass film having received the conveying force;
- and
- an auxiliary force applying unit configured to apply flows of a fluid to the free rollers to apply a rotation auxiliary force to the free rollers in a rotation direction of the free rollers during conveyance of the glass film,
- wherein one longitudinal end of the glass film has a resin sheet coupled thereto,
- wherein the auxiliary force applying unit comprises a control unit that controls the flows of the fluid, the control unit starting the flows of the fluid to each of the free rollers when the resin sheet reaches a top of that free roller such that when the one longitudinal end of the glass film reaches the top of each of the free rollers, the free rollers are receiving the rotation auxiliary force, and
- wherein the free rollers each comprise:
- a free roller body to be held in abutment against the glass film;
- and
- receiving portions formed so as to be rotatable integrally with the free roller body and configured to receive the flows of the fluid.
