To rework rolls off large slitters, Catbridge Machinery has
developed a versatile salvage winder. This 40" wide salvage slitter
rewinder is capable of handling up to 45" diameter rolls on the unwind and
rewind. Simple to load and unload, this salvage winder provides the benefit of
fast salvaging/re-working of otherwise unshippable rolls. This not only reduces
waste but prevents having to run such rolls back through a wider full web
slitter, saving valuable production time on primary machines.
The salvage winder can operate to simply unwind, trim edges
and rewind, or slit multiple webs and rewind. It can handle a wide ranges of
widths, from very wide to very narrow, as well as a wide variety of materials,
ranging from lightweight, sensitive films to heavy paper laminates. Features
include bidirectional winding and speeds to 1800 fpm. The machine also
incorporates automatic tension control with taper tension, splice tables,
defect mapping and bowed rolls in both pre and post slitting positions.
