Abstract
A thin film member forming device includes a reference roll fixedly disposed while being rotatably supported by a first bearing member, a movable roll disposed movably with respect to the reference roll while being rotatably supported by a second bearing member, a roll gap adjusting mechanism which adjusts a gap between the reference roll and the movable roll and a roll opening mechanism which expands the gap. The roll gap adjusting mechanism adds a load in a direction to narrow the gap to the second bearing member, and the roll opening mechanism adds a load in a direction to expand the gap to the second bearing member.
Claims15
A thin film member forming device of forming a thin film member with two rolls, the device comprising:
- a reference roll fixedly disposed while being rotatably supported by a first bearing member;
- a movable roll disposed movably with respect to the reference roll while being rotatably supported by a second bearing member;
- a roll gap adjusting mechanism which adjusts a gap between the reference roll and the movable roll;
- and
- a roll opening mechanism which expands the gap,
- the reference roll and the movable roll being arranged in such a manner that rotation center axes thereof are parallel to each other and an angle θ made between a plane passing both the rotation center axes and a horizontal plane falls within a range of:
- 0°≤θ≤90°,
- the roll gap adjusting mechanism adding a load in a direction to narrow the gap to the second bearing member, and
- the roll opening mechanism adding a load in a direction to expand the gap to the second bearing member.
A thin film member forming method of forming a thin film member with two rolls, the method comprising:
- fixedly arranging a reference roll while being rotatably supported by a first bearing member;
- arranging a movable roll to be movable with respect to the reference roll while being rotatably supported by a second bearing member, in such a manner that a rotation central axis of the movable roll is parallel to a rotation central axis of the reference roll, and an angle θ made between a plane passing both of the rotation center axes and a horizontal plane falls within a range of:
- 0°≤θ≤90°;
- and
- adding a load in a direction to narrow a gap between the reference roll and the movable roll while a load in a direction to expand the gap being added to the second bearing member, according to a pressing force towards the reference roll produced by self weights of the movable roll and the second bearing member.
