What the press says about LINCK

Massive investment for stem length logs

The new Linck log yard at the sawmill Decker has been in operation since summer 2014.
In shape: Decker decided for a Baljer & Zembrod butt-end reducer.
Clean business I: the log loading deck in the background, the enclosed Valon Kone debarking machine on the left.
Clean business II: The huge circular sawblade cleans the butt end for better quality evaluation.

Partnership continued on the log yard

Already six years ago, the sawmill Decker in Bertrambois/France invested in a chipper canter-circular saw line supplied by the German manufacturer of sawmill machinery Linck in Oberkirch. The higher capacity achieved led to bottlenecks on the log yard which the French company took care of last year.

During the last three decades, Linck actually has gained a reputation with the supply of chipper canter and profiling lines. That Linck also looks beyond the horizon is proven by the latest installation at the sawmill Decker located in Bertrambois, Lorraine. The flawless cooperation during the installation of the sawline – particularly with Linck project manager Martin Huber – was for Manuel Decker the reason for buying again equipment from Oberkirch. He runs the business together with his cousin Patrick.

The most recent investment however involved the log yard. „I have a lot of confidence in Linck, it is a reputable company. Even on the log yard Linck did an excellent job”, reports Manuel Decker on the occasion of the Holzkurier visit. The proximity to Linck with about one and a half hours drive also made the decision easy.

Bottleneck eliminated. Due to the higher processing capacity since the installation of the chipper canter-circular line, the log yard turned out to be a bottleneck in the last years with which a continuous supply of the sawline was no longer possible. In addition, the existing log yard equipment was outdated and there was no log scanning available. Since the summer of 2014 these problems belong to the past. “My quality of life has increased since the new log yard allows us to work without problems”, describes Decker.

The sawmill Decker exclusively buys stem-length logs. In France it is common to buy the wood standing in the forest. 50% of the 65.000 m³ round logs/year is bought standing. The buyer estimates the quantity which has to be paid – no matter what the measuring determines. The remaining 50% are bought the “conventional” way and the new log scanning system is used for payment. Decker now has a detailed and precise input control.

„Due to the restricted space conditions, the log yard was designed for a log length of maximum 18,50 m. More would have been impossible – on one side, the sawmill building limits the site, on the other side the main road”, described Linck Project Manager Martin Huber. The sawmill Decker processes logs with up to 72 cm large end diameter. These large dimensions where a log could weigh 3.5 tons and still has to be moved efficiently must now be handled on the log yard which explains the massive construction. And with the stem-length dimensions, even transport took up a lot of space. Linck as the main supplier also realised the complete control and optimising plant. Single components of the plant were bought by the company Decker.

From the truck onto the log deck. A special feature of the sawmill Decker which is not commonplace: The stem-length logs are directly placed from the truck onto the log deck and from there online into the sawline being sawn into sections. Due to the new 3D-scanner on the log yard it is possible for the sawline control resp. optimisation to continuously compare its values with those of the log scanner. After having loaded and singulated the logs, the first step is carried out in transverse movement: the reducing of the butt ends which is handled by a Baljer & Zembrod butt end reducer. A Valon Kone debarker then removes the bark in longitudinal transport. 

For measuring the logs, Decker relies on the same scanner as used in the sawline: the Microtec 3D-scanner Dishape. A Screenlog is directly installed to the scanner taking pictures of the logs to allow a more precise quality assessment and backup. At the following transverse movement, a huge circular saw with about 2,20 m diameter cleans the butt ends for a better visual evaluation of the log. A hydraulically adjustable length stop always aligns the logs to a fixed position for only cleaning a few centimetres. The logs then pass the Mesutronic metal detector. “Metal detectors are essential on log yards. Only few relics from the war times are found, most metal pieces are from agriculture such as fence parts or large nails”, says Huber. The longitudinal conveyor transports the log past the operator cabin. Large glass panes allow a good view of the whole log. Log merchandising is a matter of the boss. Either Manuel or Patrick Decker sit on the chair, as: “Money is made with log merchandising.” The whole log yard which occupies an area of 80 x 40 m is monitored by screens. A pendular trim saw cuts the 18,50 m long logs according to the optimising result which is coupled to the data from the sawline. The operator can either accept this proposal or adapt it based on the optical features. The sawlogs are then singulated and transported into the sawmill building on an about 70 m long longitudinal conveyor. “The new log yard allows a more individual and more flexible work”, says Decker. With this investment he moved a step closer to his target – the annual processing of 100.000 m³ of round logs.
