连续式沥青油毡瓦冲切工艺及设备的设计

Design of continuous punching process of bitumen shingles and its equip-ment

介绍了连续冲切式沥青油毡瓦的生产工艺及设备。此生产方式既克服了一般冲切式不能连续作业的局限性,实现了连续工作的目标,又避免了滚切式中滚切辊一次性使用的弊端。

Compared with punching pro-cess the continuous punch ing pro cess has advantage of continuous operation and with cylindrical cutting process it has no cutting roller's drawback of not being able to reuse.
