Making
Created in England from the early 1800’s, industrial papermaking was obviously a huge
catalyst towards the creation and innovation of industrial rewind slitting machines. The usage of
mechanised brakes and clutches happen to be the mainstay of many of the technologies employed
for the primary 150 years of the rewind process.
Fast forward to the Twenty-first century, nowadays the apparatus has become very sophisticated
along with the use of servo powered motors instead of clutches and drive systems that keep an eye
on, unwind and rewind tensions instantly. Automatic knife set up units have proven to be good at
reducing set up time as well as enhancing quality, unheard of technology Half a century ago.
Improvements to slitting capabilities that have powered change include driven unwind units, load
cell tensioning and infrared web diameter detection. In effect to deal with weighty parent rolls and
push the web throughout the rewind slitter, many will use driven unwinds. Load cell tensioning gives
total tension system controls particularly for tension sensitive materials. Finally, infrared detectors
are used to aid in delivering feedback to the central drive and ultimately keep the web at the proper
tension from the beginning of the master to the end.
In rewind innovations over the years, the use of continuous wind and turret wind systems have been
huge time savers to the rewind process. For continuous winders, after the roll is wound to the
proper length, the rewind stops, cuts the web, pushes the finished set out of the way, drops in the
next of cores into the rewind chucks, and the next set starts winding. The completed doff can be
palletized as necessary. On a turret wind system, the rewind system has two sets of shafts, so while
one shaft of rolls is finishing, the other set will turret in and after the finished set is cut, it turrets
away and the rolls get pulled off the rewind. In this process, the stoppage time is less than 5
seconds.

Using some sophisticated integration together with the rewinder, roll changes can be created
instantly and extremely little slowdown in the rewind slitter.
Should you run an in-house converting department or a full service converting firm, picking out the
most effective ways to ensure very little downtime as you can will reduce labor costs and boost
profits. If you use many of these modern advances mentioned above, the chances of flourishing in
what can be a competitive marketplace are very great.
