Reduce Web Nip Problems

Most nip systems move a nipping roller into a fixed roller. The nip pressure is created by controlling the two rollers' relative position through load or engagement. If you are working with a single web, avoid wrapping the loading roller. Engagement or negative gap controlled nips are insensitive to tension and wrap angles. For loadcontrolled nips, use low or 180deg wrap angles to make nip ...
