What the press says about LINCK
Rettenmeier is going to rebuild and extend parts of the sawline in Ramstein
Economical operation with present equipment not possible
The Board of Directors and the Executive Board of Rettenmeier Holding AG, Wilburgstetten as well as the Managing Directors of Rettenmeier Ramstein GmbH & Co.KG, Ramstein announced on March 25, 2010 their decision to abandon the envisaged conception of an online processing without conventional presorting on a log yard in the new sawmill in Ramstein. With an investment of about 10 Million Euro in the current year, the sawmill, which was started in stages only last year and struggled with technical problems from the beginning, will be rebuilt and extended in substantial parts. A good portion of the envisaged measures shall be completed before the end of the year. The Austrian company Springer Maschinenfabrik AG, Friesach already got the order for a log sorting plant with a total of 64 sorting bins. Several weeks ago the necessary construction work was started in Ramstein. The start-up of the log yard is envisaged for May this year. The existing log loading station with a capacity of maximum 70 linear metres/min has also to be modified to meet the higher speed of the future saw line. The turning away from online processing will also lead to modifications in the technical equipment of the saw line as well as in parts of the downstream lumber sorting.
Linck Holzverarbeitungstechnik GmbH, Oberkirch is going to replace the essential machine groups of the existing large log line. The existing saw line is equipped with machines and components of the North American machine manufacturer U.S. Natural Resources (USNR), Woodland/Washington, the company Michael Schmidt Anlagen und Maschinenbau, Viechtach and the company Prechtl GmbH Anlagen- und Maschinenbau, Burghausen.
The Linck supply volume will include a profiling line with sideboard optimisation and curve resawing. This sawline consists essentially of VM50 chipper canters, VPF- and VPK-profiler units, a circular saw CSMK, a double arbor circular gang MKV and a horizontal split saw HKM. Feed speed ranges between 50 and 160 m/min., logs of 10-55 cm small end diameter and 2.50-5.50 m can be processed.
Assembly of the sawline will start on August 16, 2010, start-up is envisaged early November. A second rebuilding stage shall be completed until april 2011. The existing small log line is not being modified, however, it is still examined to what extent it will remain in operation after modification of the large log line. The new sawline also requires modification of the downstream lumber sorting plant. According to Springer, single parts of the sorting plant have to be adapted to the higher feed speed of the sawline, e.g. changes in the destacking area. After having realised the additional investment, processing capacity can in the medium term be increased from the presently envisaged 500.000 m³ logs to about 800.000 m³ logs/year. For 2010 the company Rettenmeier strives for about 600.000 m³ logs; full capacity shall be reached in 2012. Log distribution with 40 % pine, 30 % Douglas fir, 20 % spruce and 10 % larch remains unchanged and orients itself by the raw material available in the extended radius. According to Dr. Josef Rettenmeier, Chairman of the Board of the Holding AG, only maximum 50 % of the originally envisaged production capacity could be achieved in Ramstein since start-up of the present sawmill. Main reasons were first of all interface problems between the individual parts of the sawmill due to large number of companies being involved in the project as well as basic mistakes under project work which led to the fact that the responsible Technical Manager is meanwhile no longer working for Rettenmeier (see EUWID no. 41/2009). The initiated steps shall now lead to and fulfill the envisaged capacity parameters and avoid further production losses. Regardless of the problems in Ramstein as well as of the general difficult economical conditions, the companies consolidated within the Rettenmeier Holding could achieve a satisfactory operating profit of 7.9 Million EURO in 2009 (2008: 13,3 Million Euro). The consolidated turnover was 301 (311.4) Million Euro.
