Based on first question,there are two ways:
Two feeding rollers takes place slab staggering in horizontal position. But we will debug before every NC Servo feeder leaves our factory, it can effectively avoid such situations. So this situation will hardly appear.
When feeding material, the feed rollers are not parallel in the vertical direction. The reason for this is usually due to the left and right pressure adjustment uneven of the material pressing spring in debugging process, and the weight of the one side is too light, the other side is too heavy, resulting in feeding incorrectly.
But it’s easy to solve this problem, only adjust both side pressure of material pressing spring all the same can be ok.
