FAQ -Questions that often come up-
- Face run-out with bore occurs with the cutter.
- At the time of the blade uniting has it come into contact with rubbish, dust or oil? Has the side of the cutter or spacer been scared or become rusted?
Please check the degree of evenness of the cutter and the spacer.
- Vertical wobble occurs with the cutter.
- Is there a large difference between the radius of the diameters of the cutter axial and the cutter inside?
Was the appropriate tool used when re-grinding the cutter.
- The cut surface is not good.
- Are you using the correct hand position, applying the proper pressure or have the desk at the right height?
Are the clearance and lap appropriate? Is the tension setting appropriate?
- Taking out and putting in the portable stand is heavy.
- Has the portable stand slide table been scarred?
Please seal it using an oilstone.
- Friction has no effect.
- a Has the retraction liner extended from the winding shaft point?
b Are you missing the slip board?
- Retraction tension is not appropriate, article does not stretch properly.
- Have you correctly input the settings of the operating condition?
Did you reset it before running?
- Friction tension does not stabilize.
- Is the direction of the inserted slip board correct?
Is the condition of the side of the slip board or retraction board satisfactory?
- At the time of retraction the cutting edge is damaged.
- Is the installed position of the separator/ retraction board appropriate vis-a-vis the cutter?

- Regarding operation of a tight style slitter
- With the tight style slitter when comparing to the loop style the biggest difference is that the material you will slit has tension on the front and back of it.
At the front and back of the cutter stand the material loops on the line, by virtue of the cutter's binding effect it is sent and cut.
The un stretchable material in front and behind the cutter stand is bound by the cutter stand and drive cut while being sent along the line. Using the tight style the winding pressure is applied to the cutter. Because of this the material before the slit pressure is applied to maintain balance and lessen the burden on the cutter.
In the above-mentioned setup, front and back tension balance is achieved by the setting of the brake and the cutter at the standard speed sends out the material while running the line.
In the case of the loop line, retraction tension occurs on the front of the recoiler due to the tension pad. In the case of the tight line because material is streched from the retrator to the layer there is a retraction tension/ layer brake on the respective axial rotary torques. Because the appropriate retraction tension/ layer brakes for materials vary it is necessary to ajust the settings.
- Regarding the wind roll method
- Slip winding (friction winding) is the wind roll method utilized by the tight line slitter. This absorbs the loop difference that occurs in with each article after the slit in the loop line.
Because refraction in the difference of the retraction diameter sometimes occurs in the area between the loop line because of slit material's board thickness or length deviation, when processing long material if there isn't a pit a few meters deep there is no absorption.
Because such large-scale foundation work is needed, the whole line becomes longer and time is required for the board.
Furthermore, when you use a tension pad (which is used as a general tension device) and there is a scar on the material it becomes a problem.
With the friction wind roll method a material loop is not needed when absorbing the difference in the diameter and it is able to generate pressure in each article.
Because a tension device is not needed between the cutter and the recoiler it is possible to prevent scarring on the surface of the material.
As seen in the figure the Hakusan friction wind roll system the slip board with the clutch is installed from both sides, giving lateral pressure and controlling torque and manages the tension that occurs.
When combining with the separator that automatically rises thanks to a sensor it is possible to retract narrow/ large diameter coils or multiple articles.
