Slitter terminology can be bewildering; part of the problem being that there's no industry standards for the terms used when describing various parts of the slitter and winding process. I've talked about this before so won't focus on it now, instead I'll ask you to point your clicks at this Slitter Glossary, instead I'm going to look at how we describe some of the more complex issues surrounding slitting and rewinding.
Some of terms used when describing slitter processes are conceptual, by which I mean they might describe the part of a process that isn't easily described with the written word. I had my suspicions and they were confirmed when we started work on the aforementioned Slitter Glossary. Because a lot of slitter terminology related to the movement of materials and their reactions to external pressures we have started using graphic overlays to denote movement, see below for a couple of examples.
So if you're looking for a slitter or salvage winder and want to be sure that your needs are fully understood come and speak to the experts https://www.universalconvertingequipment.com/

Driven unwind A driven unwind describes a system whereby the shaft (or shaftless system) of a Slitter Rewinder that houses the master / jumbo roll is driven by a motor. A driven unwind is often used when a material is tension sensitive, when an unwinding roll is driven it minimises inertia of the parent. |
Reversible running salvage slitterReversible running enables salvage / doctor rewinders to run in two directions, allowing print direction to be corrected without the need to unload and re-load the roll.
