High-Speed, Precise Web Handling

Designed to increase performance and enhance flexibility, WLS X-3 label head is a fully servomotor-driven system incorporating significant size reduction and design simplification over previous models. A 3-axis mounting assembly with digital settings allows for precise peel plate adjustment and product changeover in minimal time. Pneumatic core chucks are used on the unwind and rewind reels. The renowned WLS "closed loop" push-pull system has been redesigned to allow for easy tool-less disassembly and ease of cleaning.

The X-3's non-proprietary electronics have been conveniently located underneath the label head to reduce wiring between the label head and the main electrical panel, and to allow easy reconfiguration and addition of label heads onto a labeler.

The X-3 can be configured with a variety of options such label coding and inspection including serialized codes, dual label unwinds, and the Interceptor which automatically removes a rejected label prior to container application.

Backed by WLS' reputation of quality, impeccable service and customer care, and industry leading extended warranty coverage, the X-3 is built to meet the most challenging labeling demands.
