When planning and aligning the process line, the following described items must be kept in mind. If the distance is too short, wrinkles will happen on the thin or soft web.

KMT when needed to correct web position in the middle of the process line, there are two methods to modify the web edge.

Center Pivot Roll Guiding :
This method best applied to the webs of novelistic materials, or distortions web due to the difference tension of both side.
The web hardly slips on this guide roll, since there has two 90°wrapped angle. If it is slipping, use a rubber coated roll will prevent slip age occurs.
End Pivot Roll Guiding :
This method particularly good for the flexible web. It is available when the location in long distance between entry idler roll and exit idler roll. The assumed pivot of the guide roll rotation be arranged to be long, so turning angle of the guide rolls and the tension variation are lesser, will reducing the wrapping of the web. There has 90° wrap for a single roll and 180° wrap for double rolls shown below.
