The narrow paper webs which are necessary for tube winding, are cut on the slitter - rewinder. Sometimes it is not an advantage to purchase these rolls from outside sources since the web widths are often changing due to tube diameter, wall thickness, etc.
An additional advantage of an own slitter - rewinder is that it is possible to buy low-prices remnants (trim rolls), which are, however, still wide enough to cut paper strips out of them for winding.
Guschky & Tönnesmann supply two different slitter - rewinders:
The popular-priced model ABA for manufacturing simple standard rolls and the faster model ABB with automatic web tension control and all features necessary to slit the
rolls for tube winding at peak performance.
