Trimmers | Trimmer Positioning Fence & Transfer

Code: NM-MA-08-ETrimmerPositioning
Category:  Sawmilling  >  New Equipment  >  Sawmills  >  Trimmers, Sorters & Stackers  >  Trimmers

The Newnes-McGehee (NM) Trimmer Positioning Fence positions lumber accurately at very high speeds before it enters the Trimmer.

The two main components of the Trimmer Positioning system are the positioning transfer and the fence section.  All trimmer line components are synchronized through the use of an encoder and the PLC. 

Optimum cutting decisions based on Optimizer data are passed from the Decision Processor to the PLD, which controls every movement of the fence.

N/M offers three design solutions for fencing – pneumatic (air), hydraulic or electric actuation.


·         Accessibility and simple design reduce maintenance requirements.

·         Air operated skids maintain the lumber position in the transfer when fence motion is complete

·         Trimmer and positioning transfers are driven by the same source to ensure synchronized lumber flow.
