On the Tissue market it is constantly increasing the demand of bulky and soft products. The reels coming from the Tissue Machines consequently have a low density that makes them difficult to handle in rewinding and converting lines. Most of the problems, and of the limits in speed and productivity, in rewinding Super Soft high volume tissue grades, are due to the high deformability of both mother and finished reels.
The study of the technical team in Tecno Paper has been therefore mainly directed to find process solutions avoiding deformation of the reels, but at the same time allowing an operator friendly use of the rewinding line and an increase of productivity.
More than ten years ago, Tecno Paper had alreadydeveloped and installed in several paper mills a type of unwinder, named MultiFunction (Figure 1), with double unwind system: peripheral with belts and centre drive with direct connection of the reel spool to the driving motor. This type of unwinder helped to solve many problems and to increase performances, thanks to the possibility to use both systems together or separately; but in certain cases and for certain applications it was not enough.
This is why Tecno Paper has developed, and patented, also different rewinding solutions purposely dedicated to “difficult to wind” products to avoid the Super Soft reels are permanently deformed and the loss of bulk is huge. The last product which comes in to join the family of the TP-Soft Touch equipment is the new Unwinder (Figure 2), designed and developed by Tecno Paper’s technical team. It is fitted with innovative and dedicated drive and control systems for low density tissue reels, thus allowing to reach, and ensuring, high precision, accuracy and productivity for the unwind process on rewinding lines.
