Automatic sleeving splicer

摘要

A system and method for automatic splicing of rolls of sleeve material used in various packaging markets is provided. The system will automatically splice the prepared end of a new roll onto the expiring end of the prior roll. The system performs an automatic cut and splice operation resulting in a butt splice of the two rolls with tape applied to both sides of the splice joint. The splice can be done in-registration to provide a consistent product repeat length between expiring and new rolls.
