<p>PURPOSE:To blow away an offset preventing liquid staying excessively at a peeling pawl, by blowing air to the peeling pawl as required. CONSTITUTION:Fixing rollers 1 and 3 rotate with the driving force of motor 13. In shaft 16, electromagnetic clutch 17 is incorporated, pin 19 is loosely fitted to link plate 20, and plate 20 is also loosely fitted to pin 22 fixed to sliding plate 21. The end part of sliding plate 21 reciprocating by being guided by pins 23 and 24 is fixed to the end of flexible air bellows (pump) 25 and the other end of pump 25 is linked to ventilation pipe 9 via change-over device 26. Therefore, when electromagnetc clutch 17 is excited to suck armature 18, armature 18 rotates to put link plate 20 into crank motion. Then, sliding plate 21 reciprocates as shown by the arrow to expand and contract pump 25, thereby blowing air from the circumference of each peeling pawl via ventilation pipes 9a and 9d.</p> |
