摘要：PURPOSE:To carry out the change of mold rolls easily and accurately, and make the change-working time shorter by moving a press roll and a separation roll to the position not interfering with the pulling out of a turret mechanism, and pulling out the mold roll turret mechanism, and rotating them then. CONSTITUTION:By the use of a manufacturing apparatus, line speed is reduced, and the peripheral speed of a primary mold roll 11a is synchronized with the reduced speed of the line speed by driving a driving gear 23a. Next, a press roll 17 is moved from 17a to 17b in 0.2-5 times of the roll diameter, and a separation roll 18 is moved from 18a to 18b at 60-150 deg. on a circular orbit. A driving gear 23 is reduced in its speed, furthermore, stopped then, and the primary mold roll 11 is reduced in its speed and stopped, after that, a driving gear 23b is moved away, and a mold roll turret mechanism 21 is further moved from 21a to 21b, the mold roll is changed, for example, from 11 to 12 by separating an attached device and rotating the turret mechanism 21b.
