Splice-related CD tension variations are characterized by appearing before or after a splice, following the splice as it travels through the web line, and disappearing after the splice passes into the winding roll.

Solutions

Solutions to CD tension variations from web splices:

  • For zero-speed manual splices, install and use a splicing table with clamps and reference lines.

  • For zero-speed automatic splices, ensure the web is aligned in setting up the incoming web properly.
