Re-stacking lines

Depending on the requirements, re-stacking lines are used for stacking, sorting, cutting and repeatedly stacking sawn timber. For the purpose of re-stacking, the stacks are unstacked layer by layer using a tilting, vacuum or stripping destacker.


The stacking strips between the layers are collected and either kept for re-use or sent to disposal.


The unstacked timber is separated and the individual boards can be assessed and sorted by an operator. Our grading stations for the assessment of timber allow – depending on the design – the visual inspection of the wood surface on all 4 sides. The quality grading can be done manually by one or more employees, or automatically, e.g. by using our „mtgBATCH“ mechanical strength grading system. A combination of manual and automatic grading is also available.


The assignment of the quality to each board can be done in various ways. In manual sorting, for example, by pulling or pushing the boards by hand and reading the position of the board using light scanners, or also by pushing buttons. In automatic quality sorting, the data determined by the scanner are virtually linked to the respective board.


To prevent a wrong sequence and therefore incorrect quality assignments of the boards within a sorting line, we provide various mechanisms for sequence and plausibility checks, such as, e.g., the unique marking of the boards.


Following the sorting process with ejection of defective or goods containing to much moisture, the timber is usually cut at the front side to exact lengths and stacked to new, unmixed packages.
