Different machining concepts depending on the finished product
are available. Basically we distinguish between vertical and
horizontal finger joints, batch-fed and through feed machines.
BATCH-FED MACHINES: The blocks are positioned on edge
with ends indexed to one end clamped together and run past a
cutter that profiles the blocks.
THROUGH-FED MACHINES: The lumber is fed by means of a
chain. The blocks are transported past the cutter.

Vertical Cutter
Vertical finger joint machines are commonly used to produce
large laminated beams with span sizes of 50m and more.
Typically the finger joint length ranges from 15 mm --- 25 mm.
Horizontal finger joints are commonly used in the production of
structural and non-structural products. The joint length ranges
from 4mm to 10mm in case of millwork joints and up to 20 mm in
case of structural joints.
Non-structural finger jointed products are door and window frames,
mouldings, door jams, casings etc. Horizontal finger joints can
also be found in laminated beams, I-beams and dimensional
construction lumber.
Besides different machining concepts and finger joint length, we
also distinguish between different joint types.
Most common is the Reverse type, followed by the Male-Female
type.
Re-saw is a special joint with a thicker finger at the center of the
block, allowing the block to be re-sawn into two pieces.
The scarf or feather joint is mainly used in the production of
structural timber.
