Tension effects on web slits

  1. Feb 12, 2008 #1
    Hello everyone,

    I have a question about the tension effect of spreading out a slit web over a short distance. We are installing a web cleaner that requires 40 - 3/8" or 5/8" slits be brought through it with a short distance between one another. I've designed a shaft that will keep each individual web 1/8" apart from each other, but over 40 cuts, it means the web will increase in width from 25" to 29.75" over a span of only 22 inches of material. The kicker is that this product needs to be run at low tension and high speed. Will this fan-out create a large amount of tension, especially on the outside strands, which will be displaced about 2.5 inches over a short amount of material? Thanks in advance for any suggestions.
