Machinery concentrates on achieving high recovery
ARI AB was founded in 1918 and Vislanda Sawmill machines in 1964. The two companies merged in 2002 and the name was changed to AriVislanda AB with the speciality being circular saw technique for both companies.
Worldwide there are many sawmills using equipment from AriVislanda systems installed in all the radiata pine countries including Australia, Chile and New Zealand.
“It highlights the fact that we have a great deal of experience in the systems required for different production requirements you may need,” says Thomas Wästlund, AriVislanda AB Marketing Manager.
“The key question for us has always been high recovery which is obtained by handling the logs as individuals, i.e. each log is different and must also be treated as that. If the log not is handled correctly in the primary sawing group the result can never be optimal,” Thomas said. In the beginning of 90´s Ari developed a log rotator of rotor type for a high accuracy in the log rotation process.
Ari was also one of the first companies to start curve sawing with circular saws. This is today used in many sawmills around the world.
From 2002 to today continual development has gone towards doublearbour log edgers replacing earlier log edger types with big sawblades. It is also possible to get these machines with “built-in” profiling to eliminate board edger’s in the line, if a profiler is also added in secondary breakdown.
“As mentioned previously, AriVislanda is a pioneer when it comes to curve sawing which is important for the recovery in the secondary breakdown.
“For many years we have supplied so called mechanical curve sawing,i.e. guidance of the cant is following the outer part of the cant by various hydraulic pressure to the mechanics. Today it is possible to have controlled cant guidance where the cant is scanned with high resolution laser scanners and the cant is guided through a second canter with servo controlled side rolls.
“From beginning of 2014, AriVislanda has also started manufacturing log handling equipment as a company based on earlier Interlog and Kentab technique was acquired. AriVislanda can today offer log sorters, logintakes and equipment belonging in this area of products.
From March this year, AriVislanda is cooperating with Peter Cooper of HOLTEC Timber Technology, as our representative for Australia and New Zealand. We will be present at WoodTech 2015 in Melbourne and Rotorua and everyone is invited to see us there.
