Winders and Unwinders: Italian technology for sheet metal processing without machine downtime

Unwinders and rewinders (or coilers) are fundamental components in sheet metal processing lines. While the unwinder (or uncoiler) unrolls the mother coil, feeding the metal strip towards the press, the rewinder rewinds the processed material, ensuring constant tension and operational precision. Elmea designs and manufactures uncoilers and rewinders with 100% Italian technology, built with sturdy electro-welded steel structures to ensure stability and durability.

Distinctive technical features:

• Design versatility to customise each machine according to the dimensions and specific characteristics of the coils to be processed
• Hydraulic expansion system of the self-centring device (manual up to 1,000 kg capacity)
• Internally designed oil-bath bronze gears for reduced maintenance and optimal performance
• Disc brakes for precise adjustment of the unwinding force
• Intuitive interface that allows use without specialised personnel
• Motorised and idle roller models available

Each rewinder and winding reel can be integrated with compact feed lines, motorised straighteners and electronic feeders to create complete press servo systems.
