Overview

ProFormer

The ProFormer is the most rigid, most advanced, and highest performing curving canter profiling system on the market for processing up to 12 inch cants. The ProFormer consists of counter rotating dual-head canters and vertical axes to equalize cutting forces on the center of the cant. The variable profiling heads can achieve vertically slewed sideboard solutions that competitor pocket profilers cannot provide. Coupled with the ProScission it is simply the best secondary breakdown solution available in the industry.

ProScission

The ProScission is the most rigid, most advanced, and most accurate curve sawing gang on the market for processing up to 12 inch cants. RPM offers both single arbor 6" and double arbor 12" versions that utilize 19" saws with 0.130" kerf. With all electric actuation and large 25 inch diameter skew bearing makes the positioning accuracy as close to perfect as you can achieve. This system is running today at 450 fpm on 12 inch Douglas Fir cants, curve sawing at a 200 ft radius on all cant thicknesses. The overhead mounting of the arbor motors on the sawbox provide extraordinary balance and control. Combined with ideal curve path controls the precise movements of the ProScission produce lumber quality and production that is unrivaled. Added features such as a no tools required one button automatic locking arbor door and on-the-fly top to bottom saw mismatch adjustments, will increase mill up-time and production. Coupled with the ProFormer it is simply the best secondary breakdown solution available in the industry.

HOTT (Hanging-Over-The-Top) Technology - ProFormer

  • Minimal footprint that typically fits into the existing Gang Infeed Module
  • Rigid structure for maximum machine stability and accuracy
  • Close coupling of Infeed and Mid-feed Press Rolls provides superior cant stability through the Canter/Profiler and into the Gang Sawbox
  • Innovative design allows plumbing, cables, and "moving parts" to be located out of the main debris area. This results in reduced maintenance requirements for items such as linear bearings and cam followers, while also reducing the risk of electrical cable and plumbing failures
  • Easy machine access and built-in service lights for routine inspections, knife changes, and maintenance
  • Reduced cleanup and easier path for chips/debris to waste conveyors

Double Canter Head Design

  • Does not influence cant path
  • Vertically slewed profiled board solutions
  • Press Rolls set to cant thickness
  • Canter sets vertically to center of cant thickness

Curve Profiling

  • +/- 6 degrees of skew with Canter Profiler Heads
  • Profilers pivot independently of Canter to accurately follow curve path
  • Currently running 200' curve radius on all curve thicknesses

Fully Pre-Wired and Factory Tested

  • On-board I/O Enclosure with all devices factory pre-wired and functionally tested
  • Ethernet valve technology allows for factory tested axis pre-wiring to remain in-place during shipping which reduces on-site commissioning time
  • Simplifies on-site electrical installation process

All Electric Curve Sawing

  • All electric slew and skew axes
  • Virtually zero following error
  • Most accurate Curve Sawing Gang on the market
  • 25" diameter four point contact bearing for skew pivot
  • 3" Thomson Roller Roundway bearings for slew
  • 3" Ball screws for both slew and skew axes
  • Top arbor adjusts to curve path and cant thickness
  • Shortest roll to roll distance between cutting tools possible
  • Super short, rigid saw guide design greatly improves accuracy

Single 800 HP Motor Per Arbor

  • No Jackshafts, motors belted with Polychain directly to the arbors
  • Clutches attached to motors prevent belt breakage
  • Single tensioner pulley per belt
  • Motors mounted close to skew axis keeps inertia low
  • All six outfeed rolls driven by single 140 roller chain and drivelines

Automatic Locking Arbor Door

  • No tapered bolts used to keep arbor door closed because they wear significantly resulting in poor arbor alignment
  • Much safer design, door will not open until arbors are completely stopped
  • Fail safe design, only requires power to unclamp
  • Door slides out on a linear rail and bearing, then pivots open, allowing easier handling and no door sag
  • Arbor uses pull-stud design, similar to CNC machine spindle, pulling the arbor and nose cone tapers together
  • No tools required. Arbor pull stud pushes nose cone from arbor upon release of tension (See in action)

HOTT (Hanging-Over-The-Top) Technology - Proscission

  • No support structure below Sawbox provides a direct path for chips/sawdust to waste conveyors and eliminates areas for debris to build up
  • Top mounted linear guideways are easy to maintain
  • Designed without chip heads in Sawbox, allowing feed rolls to be close to saws and allow reliable processing of shorter cants
  • Arbor motors, mounted flat on top of Sawbox and not on their sides allows for easy motor service and replacement
  • Easily adjustable tensioners on poly chain belts that drive the arbors ensures proper tension is maintained on these belts
  • Single motor design reduces the number of poly chain belts and sprockets and eliminates jack-shafts and their bearings
  • Reduced inertia for skewing, due to motor mass being tight to skew pivot axis, allowing for faster more precise sets
  • Motor cable management improved with limited motor movement and the addition of cable track and single J-box location on frame
