这四辊板轧机适用于金属板的弯曲和形成。它可以在一定范围内滚动，弯曲和锥形工件，并且具有预先弯曲板的端部的功能，剩余的直边较小，工作效率高。金属板可以大致水平在该机器上。板弯曲机的上辊通过液压缸中的液压油作用在活塞上，在两个下辊的对称位置，用于垂直提升运动，并且主减速器的最终齿轮驱动两个下辊齿轮以接合在旋转运动中为轧制板提供扭矩。

平塑料金属板的板滚筒机通过板式滚动机的三个工作辊（两个下辊和一个上辊）之间的通过，并且金属板通过上辊的较低压力和较低辊连续弯曲的旋转运动来通过多次通过，导致永久塑性变形，卷成所需的气缸，锥形或部分。这种液压三辊弯曲机的缺点是纸张的端部需要被其他设备预弯曲。板式轧机适用于板厚超过50mm的板厚的大型平板轧机。一排固定支撑辊在两个下辊的下部添加，以缩短两个下辊的跨度，从而提高轧制工件的精度和机器的整体性能。
