Take-up roll mandrel slip clutch tensioning device |
摘要 |
A tensioning device for the take-up roll in an automatic laminating apparatus is characterized by a clutch member attached to the roll, the clutch member having a clutch material thereon biased into an abutting interface with respect to a drive member. The drive member is rotated at a first predetermined angular velocity. The clutch material continuously slips along the interface with the drive member to impart a second, lesser, angular velocity.
