摘要:
Proposed is a friction shaft for a slitter that enables a winding pipe to stably roll unit materials formed by cutting a raw material, such as a raw fabric or film, with predetermined intervals, that can fix the rolling pipe even at a low pressure of compressed air, and that has a wide range of available rolling tension because the pressure range of compressed air that can adjust winding torque is wide.
