Lineal (linear) gang edger feed speeds to 700 feet per minute.  Piece counts to 35 pieces per minute on 10′ lumber.

The Horizontal Shape Saw (HSS) is a floating virtual-pivot sawbox.  High-resolution scanners simultaneously scan the cant as it is fed into the slew/skew gang edger.  Cants can be fed to the scanner centering table from one or both sides. 

Horizontal Shape Saw (HSS) single arbor system without chipping heads   Floating virtual-pivot sawbox.

Curve sawing gang edger features the skewing and slewing CNC saw module.  High-resolution scanners (up to 3 scanners) simultaneously scan the cant as it is fed into the slew/skew gang edger. Cants can be fed to the scanner centering table from one or both sides.

Saws are stationary throughout the curve sawing process.  Controls curve of the cant from the beginning to the end.  Four foot gap required for maximum throughput in random lengths.

Curve sawing, shape sawing and straight sawing.  Compound curve sawing.  Speeds to 600 feet per minute. 3′ gap on non profiling, 7′ gap on profiling.

Curve sawing, shape sawing and straight sawing.  Compound curve sawing.  Speeds to 600 feet per minute. 3′ gap on non profiling, 7′ gap on profiling.

Straight sawing.  Speeds to 600 feet per minute.  Available in single or double arbor.  Guided saws.  Narrow kerf straight sawing.

Curve sawing with speeds to 600 feet per minute.  Curve sawing and straight sawing.  Compound sweep (shape) sawing capability.

Functional Description

Gang edgers are used to saw cants into boards.  Gang edgers can be single arbor or double arbor.  There are horizontal arbor and vertical arbor gangs as well as straight sawing and curve (shape) sawing gangs.

Single arbor gang edgers have the saws mounted on one arbor.  This is usually a bottom arbor.

 

Double arbor gang edgers have saws mounted on a top and bottom arbor.  In some cases the bottom saw will be larger than the top saw.  For example on a ten inch gang the bottom arbor may saw up to 6″ cant widths in order to avoid any potential saw step in the six inch lumber.

Horizontal arbor gang edgers have the arbor(s) mounted on the horizontal plane with the saws being vertical.

 

Vertical arbor gang edgers have the arbor(s) mounted in the vertical plane with the saws running horizontally.

Straight sawing gang edgers saw parallel to a line bar or the cant is positioned to the gang and fed in parallel to the saws.

Curve sawing, or shape sawing, gang edgers saw to the shape of the cant.  There are basically two types of curve sawing.  One uses articulating and translating saws to follow the shape of the cant.  The other method moves the cant shape around the saws.
