Abstract
PURPOSE: To insert and remove a tube smoothly and quickly without giving damage by properly adjusting the position of a grip and receiving rollers when the tube is fed to and pulled out from an expander.
CONSTITUTION: A gripper 2 is set so that when a tube P is fed to an expander 1 a holding part 23 comes to the first position A where the holding part is positioned at a height H1 from the floor surface, and when the tube is pulled out from the expander 1, the holding part 23 is positioned at the second position A2 where it is at a height H2 (H2<H1) from the floor surface. On the other hand, receiving rollers are set at the first position B1 where the upper peripheral face comes at a height of R1 when the tube P is fed to the expander 1, and at the second position B2 where the height is R2 (R2>R1). By this way, the tube P can be kept always concentric with the expander 1 and the generation of flaws on the inner face due to contact with the expander 1 can be prevented.
