It is important to do precise control during slitting process because the quality of the slitting will directly affect the quality of the finished product. So you need pay attension to some points when using slitting machine.
1. Cutter position
We must put cutter in correct position to let the slitting job accurate, if the cutter position is not correct, it will slit in the wrong position and it cause prodouct waste.
Also the distance between cutter and groove roller should be considerate according to film thickness.
2. Tension control
Tension controlling playing a very important roll in slitting process, if tension is too big, the material will be too tight, if tension is too small, material will be loose and it is difficult to do precise slitting when the material is loose.
3. Speed control
When we run the machine, it is important that do not increase and decrese speed too fast. It has rection time for the machine to catch the speed change and material will go left or right.
4. Edge control
It decides the edge of rewinding roll is flat or not. For transparant film, we must focus the light of EPC on the edge of roll, so during slitting, when the material go left or right, the edge controller can pull the material back to right position. When we slit printed material, we can focus the light of EPC at printing line. Once the EPC lost the tracing, the material rewinding will be very bad.
Only understanding how to do precise control at all the points during slitting, then we can get best product . Ruisu Machinery manufactures the best quality slitting machines to meet customer needs for different types of machines.
