High Speed Vertical Roller (VR) In-Line Labeler

Request More Information ›

Ultra-High Speed, Precise Labeling

Designed for the application of a film or paper pressure sensitive label onto round containers, the WLS VR in-line labeler combines a modular platform with a breakthrough vertical roller track design that references the container sidewall for consistent and precise label application. The VR fully synchronized electronic drive train also allows for ease of operation and fast changeovers via HMI-based recipe control. This construction ensures years of trouble-free operation at highest efficiency levels with minimal maintenance requirements. The VR comes with a zero-access guarding package, meeting the most stringent safety standards.

The VR can be configured with a variety of options such as single or redundant label heads, removable rollers for quick container size and pitch changes, label coding and inspection including serialized codes, RFID tags integration, patented Reconciler feature, and 21CFR Part 11 and CE compliance. The WLS patented Reconciler removes, counts and rewinds rejected labels prior to their application onto a container.

The VR is the latest update in our long history of robust machine designs. Backed by WLS’ reputation of quality, impeccable service and customer care, and industry leading extended warranty coverage, it is built to meet the most challenging labeling demands.
