PURPOSE:To simplify a titled mechanism and to reduce trouble by executing vertical motion of a pressing roll with an eccentric sleeve fixed to a shaft. CONSTITUTION:A pressing roll 2 is installed vertically movably with respect to a fixing roll 1. The roll 2 has a bearing 3 in the inside circumference and a shaft 4. The shaft 4 has eccentric sleeves 5 on both ends and also a gear 7. This gear 7 is engaged with a gear 9 having a worm wheel 8, and disengageably fixed. The wheel 8 is connected with a drive source through a worm gear 10. The gear 9 is fixed with a shaft 13 to an idler bracket 12 turnable on a stud 11 as a pivot. The bracket 12 is connected with the plunger 16 of a solenoid 15 through a spring 14. The pressing roll 2 can be held in pressure contact with the roll 1 and released from contact with the roll 1 by rotating the eccentric sleeve 5. |
