Jan 13, 2006. /Lesprom Network/. Tolko Industries, Ltd., Canada, ordered from Siempelkamp Maschinen- und Anlagenbau a forming and press line with a ContiRoll® press for the company’s new OSB plant in Slave Lake, Alberta. With a length of 70.3 meters and a width of 8.5’, this press will be the longest ContiRoll® press ever installed. A distinctive feature of the line will be the Contitherm® preheater which is used to heat up the OSB mat before entering the press. This preheater is key for the high line capacity and allows making products with superior qualities and in a wide range of thicknesses. The line is designed for a maximum speed of 256 fpm (1,300 mm/sec) and an annual capacity of over 825 MMSF (3/8” basis) (730,000 m³) of 7/16” OSB. Therewith, Tolko owns the most powerful continuous OSB press worldwide. Erik Munck,Tolko’s engineering manager for the project comments that the forming and press line will allow Tolko to produce high-quality structural engineered wood products with great flexibility as far as resin combination, board format and board thickness are concerned. The Siempelkamp subsidiary Büttner will supply two (2) strand dryers. The cooling and stacking line, the storage system and packing line will be from Siempelkamp Handling Systeme (SHS). A special feature by SHS is the triple diagonal saw system installed directly after the press. Even at full speed this saw is able to produce boards with a length of down to 8’. The start of installation for the Tolko press in Canada is scheduled for January 2007. Another order for a Siempelkamp forming and press line was placed by one of US customers. The world’s largest manufacturer of OSB, Louisiana Pacific Corporation, decided to open another plant in Thomasville, Clarke County Alabama. The recently by Siempelkamp developed concept of a 12’ multi-opening press, one of which is currently being starting up for Canfor-LP in Fort St. John, Canada, will be used again. The hotplaten format for Thomasville will also measure 12’ x 34’; the press will have 10 openings and an annual capacity of 700 MMSF (3/8” basis) (620,000 m³) of 7/16” OSB. This upstroke press has a modular press frame design. The vertical frame components are held together by upper and lower cross beams to form the press frame. Because all parts are connected either by bolted joints or by interlocking joints, instead of being welded together, a high fatigue strength is ensured. The extensive Siempelkamp expertise is reflected in the design of these frame beams. The beams are cast from ductile iron in our Siempelkamp foundry in Krefeld and then machined in the adjacent machine shop. This process creates a rigid monoblock design that will well take the press forces. The press table and the press beam are also cast from ductile iron which will influence the stability and deformation behavior of these parts positively. The foundry’s well-founded experience of many years has become a big competitive edge. The company is one of the few foundries that is able to produce castings of up to 330 US tonnes. The LP press will consist of only a few movable parts. The reason is simple: the less press parts are exposed to wear, the less service and maintenance is required. Another advantage of the new modular design of the press frames is the relatively simple transport of the parts, as well as a quick installation onsite. The new press will be the vital part of the combi-line. Siempelkamp has sold this type of line 19 times in North America. The scope of delivery for the new OSB line also includes 4 matformers for the surface layer and 2 matformers for the core layer. Installation start for the Siempelkamp equipment will be in the second half of 2006. The Siempelkamp Group is a corporate group which, with its separate business units, is an international supplier of equipment to industry covering diverse market segments.
