制革的一个工序。用手工或机械力量将革展平的操作。目的是消除革面皱纹，使革身平整紧实，粒面平细，降低革的延种率，增大面积。平展前要按成革品种和质量要求，使革匀湿到适宜的含水量。例如要求粒面紧实挺括的鞋面革应比软型革有较高的含水量。平展机型号很多。①辊式平展机：属刀轴类设备，送料辊和钝刀平展辊均为长型辊，用于轻革平展。②鼓型平展机：送料辊呈鼓型，短刀鼓可左右移动，用于重革平展。③热辊平展机：皮革经机器上的加热送料辊和其下的支承胶辊的熨压，使革身平展并有一定干燥效果，适用于轻革。④辊熨平展机：下送料辊为加热辊，革经加热辊、上压辊及钝刀辊的相对运动而获平展、轧光和熨压效果。⑤无夹平展机：将革直接置于上下两块圆形橡胶板之间，在真空和液压作用下，将革向四周拉伸而获得平展及干燥效果。
