UWR Industrial Label Dispenser
The UWR range includes label dispensers designed to automatically feed a printer with rolls of self-adhesive labels.
Positioned at the start of the line, they ensure a regular and controlled flow, essential to guarantee quality printing and avoid production stoppages.
They are particularly used in complete installations:
Unwinder (UWR) → Printer → Rewinder (RWR)
Smooth operation and continuous feeding
UWRs allow for consistent label unwinding thanks to:
a rigid and stable structure
precise coil support
a smooth feeding schedule
This ensures continuous printing without operator intervention.
Synchronization with the printer
The system is designed to:
automatically adapt to the printing speed
follow the cycles of advance and retreat (backfeed)
avoid excessive tension on the support
This ensures reliable and uninterrupted production.
Compatibility with industrial printers
UWRs are compatible with the majority of printers on the market:
Epson
VIP Color
Primera
Afinia
Neuralabel
They integrate easily into an existing line.
DX/SX versions (right/left)
