Sawmill concept for processing raw timber from 10 cm to 25 cm on the top (thin side of the log).
The Profiling line is constructed the way, that pre-sorted wood in bark is moved into the line infeed-system . As required the timber can also be cut once in the middle. The shorter the log is, the straighter is becomes .
The infeed-system with centring transfers the logs into the Rod rounding machine, p. ex. Type RHM 250 II-H. The RHM suits to optimize the wood nature, i.e. butts, knot seats, curved form are smoothed. In this way the non-stop working of “logs with difficulties” is assured.
Leaving the RHM the round milled logs are transferred into the Profiling–and Sawing machine Type PSM 250. In the PSM, the cylinder is processed using double-shaft technology. This technique enables smaller kerfs, which increases the yield, especially with small timber. Here, a module (or a double module) and 2 or 4 prismatic side boards are sawn.
In addition, the side boards are separated from module by transporting with special conveyor.
The module follows into the Multi-rip Saw for horizontal cutting where it is cut to patterns in flexible combination.
Saw-milling products are used for production of pallets, parquet, elements for laminated beams etc.
This profiling technology can economically process “ simple” wood like e.g. spruce as well as “difficult” wood like e.g. maritime pine.
The engineering and production are made in accordance with individual ideas and special requirements of the customer.
The Wema Probst technology has some economic advantages such as e.g.top output of small wood, up to 65% depending on the sawing patterns and its lengths, low requirements for installation area (the overall length of the line for working the wood up to 3 m is 30 m),
low primary energy costs – appr. 360 kW – 450 kW, high throughput capacity up to 50.000 fm . p.a.
The line is also a useful addition for large sawmills in order to utilise small timber more sustainably and cost-effectively.
