Abstract

PURPOSE:To prevent creases of a base original tape surface due to the pressing of rolls, by preheating a base original tape by providing a preheating roll right in front of the top roll of a calender for a magnetic tape. CONSTITUTION:Preheating roll 6 is provided right in front of top roll 3 of a calender for a magnetic tape and at its one terminal, a heater is provided to heat roll 6. Then, fan-shaped roll receiving plate 17 provided closely with small roll 10 along the flank of roll 6 is fitted to gear 15, which is engaged with actuating gear 16 equipped to an oscillatory motor. For this purpose, base original tape 2 is wound around preheating roll 6 and preheated and then worked while running through the pressure welding surface between top roll 3 and elastic roll 4. Further, while the calender is not in operation, gear 15 is rotated by 180 deg. to wind base original tape 2 around small roll 10, so that heating can be avoided.
