Document Type and Number:
WIPO Patent Application WO/2023/067904
Kind Code:
A1
Abstract:
According to the present invention, a flotation roller (20a) uses a force that acts on a conveyed workpiece (W) without making contact in order to support the workpiece (W) in a non-contact manner. The flotation roller (20a) has a tubular shape extending in the width direction (B) of the workpiece (W), and at least a surface thereof facing the workpiece (W) is formed from a circumferential surface. A driving unit (20f) rotates the flotation roller (20a) in the yaw direction. Among the holding angles of the workpiece supported in a non-contact manner by the flotation roller, the holding angle of the inside from a topmost point and the holding angle of the outside from the topmost point are configured to be different angles.
