Pressure Sensitive Label Head X-4S

High-Speed, Serialization-Capable Web Handling

Designed for maximum performance, enhanced flexibility and allowance for high-speed serialization, Weiler Labeling Systems' X-4S label head is a fully servomotor-driven system which can handle the most demanding applications in an even smaller package. An independent 3-axis mounting system with digital settings allows for precise peel plate adjustment and product changeover in minimal time. A new web tension and feed control system from the unwind through printing allows for continuous-motion code printing, even when the labels are being dispensed in indexing mode. In addition, the renowned WLS "closed loop" push-pull system allows for easy tool-less disassembly and ease of cleaning.

The X-4S'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 for easy reconfiguration and the addition of label heads onto a labeler.

The X-4S can be configured with a variety of coding options and inspection methods as well as dual label unwinds and an 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-4S is built to meet the most challenging labeling demands.
