Wood Production Technology
More than 400 Grenzebach plants are in use for veneer production worldwide. Stacking speed during sorting is up to 300 meters per minute. Consistent drying across the entire dryer width and all decks is our specialty. Eight deck dryers with up to 6.2 meters working width are currently in use.
Six decks and 50 metres
is the length of the worldwide longest veneer dryer, made by Grenzebach.
Grenzebach's new Staylog machine has been developed in close cooperation with the market leaders in the veneer production industry. The precise adjustment using a hydraulic linear amplifier has been successfully implemented for the manufacturing of high quality veneers.
Grenzebach has met industry demands with first-class solutions, such as the possibility of tilting and the adjustable bearing surface of the Staylog. Speeds up to 120 sheets/min are reached. The Staylog machine is available in various options up to a working width of 4 meters.
More than 50 years of experience, more than 400 systems implemented worldwide, and the world's longest dryer at 50 meters length are just some of the key facts of Grenzebach drying systems for decorative and rotary cut veneers. Grenzebach stands for uniform veneer drying over the entire width of the dryer and throughout all the levels - performance due to precision air distribution and uniform flow. In the transport process, the sine-shaped path ensures minimum ripple. We provide;
Belt dryers for rotary cut veneer, especially for thin designs and continuous veneer
Roller conveyor dryers for rotary cut veneer that are thicker and / or large size
Press dryers for decorative and smooth-surface veneers
Grenzebach's stacking systems allow for several stacking stations with only one continuous veneer transport system. This ensures optimal veneer stacking quality on the lifting platforms located under the stacker.
Various automatic solutions, tailored to suit the customer's requirements, are available for removing the stacked veneers and feeding new empty pallets.
Optimal tuning of the stacking system individual components ensures reliable stacking of even thin and sensitive veneers.
Grenzebach has the world's longest stacking system with a 40 m length and 15 stacking stations.
Modern drying lines with automatic stacking systems can dry and stack large quantities of veneer sheets in different sizes and thicknesses without operator intervention. Grenzebach's veneer scanner FPI veneer is essential to ensure quality and uniform sorting. The scanner detects all defects that are to be considered while sorting the veneers. Depending on the moisture, the precise stacking station at which the scanned sheet will be stacked is determined within seconds.
Our feeder systems are specifically designed to meet the production requirements of various veneers. For example, while feeding decorative veneer into the dryer is a semi-automatic process, feeding rotary cut veneer is fully automatic. The feeder system features a vacuum-assist to lift the cut, wet veneer sheets and transport them to the dryer at high feed rates.
Grenzebach's vertical veneer slicers have been developed in close cooperation with market leaders in the veneer production industry. They have proven themselves in the production of high-quality veneers.
Market demand prompted development of an option to tilt the central section of the machine using a hydraulic linear amplifier. This has been a huge success, enabling cutting speeds of up to 105 sheets/min.
The vertical slicer comes in working widths of 4.0 and 5.2 meters and features various options.
