SLP evolves in response
to market demand
Wood-Mizer developed the Small Log
Processing (SLP) line to provide an
efficient and economical way to process
small logs while achieving good
productivity and high yield of sawn
boards.
SLP lines are designed to customers'
requirements from a choice of twin and
single vertical bandsaws, multi-head
horizontal resaws, and associated log
handling and conveying systems. The
addition of a Wood-Mizer edger or
multirip offers customers the ability to
add further value and productivity.
These lines have been installed for
customers around the world since they
were introduced in 2007, and are used
for cutting a variety of species and in a
range of environments. Wood-Mizer has
always encouraged feedback from all
customers, so that the technical design
team can enhance the performance of
machinery and blades to meet the

changing needs of sawmillers. For the
SLP line, this has led to a number of
innovations.
One of these is the 'Spiky Chain'
system for feeding logs through the TVS
twin vertical bandsaw. This was initially
developed in order to increase
productivity. With the standard 'dogged'
feed chain there will always be gaps
between logs, as each one has to pause
on the deck until the next dog (usually
spaced about 170mm apart) on the
chain arrives to feed the log through the
sawblades.
"The Spiky system is a continuous
spiked feed chain with overhead spiked
rollers before the saw", said Roman
Frontczak, technical director at WoodMizer Industries. "These grip the log as
soon as it is positioned on the special 'V'shaped loading table, which means logs
can be fed butt to butt with no gaps
between them. Depending on the length
