DTM RW-7 Label Rewinder and Unwinder
If your printer produces labels wider than the RW-4 can take, the RW-7 provides a powered rewinding station for rolls up to 177.8 mm wide. It collects printed output into an aligned roll ready to store or load into a compatible applicator.
The same unit can serve as an unwinder in a suitable printer setup. Its extra width comes with a smaller maximum roll diameter than the RW-4, so check both measurements rather than choosing by width alone.
