求翻译：（1） 如果片料太硬，可降低压力，或加快压轮转速，或降低送料电机转速，两压轮之间间隙为0.2-0.5mm。是什么意思？

(1) If the film material is too hard, can reduce the pressure, or speed up the roller speed, or reduce the feeding motor speed, the gap between the two roller for the 0.2-0.5mm.

( 1) * If film too hard, it can reduce pressure information, or to speed up or reduce pressure roller speed, feed, rotational speed gap between two Pressure roller for 0.2 - 0.5 mm .

(1) If the piece material too is hard, may depressurize, either speeds up the pressure roller rotational speed, either reduces the feeding electrical machinery rotational speed, between two pressure rollers the gap is 0.2-0.5mm.

(1) if the material is too hard to reduce the pressure, or accelerate the pressure wheel speed, or reduce feed motor speed, clearance between the two rounds of 0.2-0.5mm.
