Lineal Log Merchandiser

Murray-Pacific has just introduced its new Lineal Log Merchandiser Dual Cut-Off Saw system, with a second moveable saw that increases the flexibility and productivity of the merchandiser. This system, which can communicate with other PLCs currently in use, utilizes proven AC flux vector drive and positioning technology that has been successfully used on previous installations. Log scanner data is used to position the second saw as the tree-length stem is being advanced through the merchandiser. Once the stem has been accurately positioned, both saws are cycled so that two segments are generated at the same time. While the new dual merchandiser is available in numerous configurations, the current system simultaneously bucks into 8', 10' and 12' lengths. A second unit is capable of simultaneously bucking log segments from 12' through to 20' lengths.

All Murray-Pacific Lineal Log Merchandisers are capable of bucking odd and even lengths, or any length the sawmill requires. The new system is also fully automatic and can be interfaced with transverse or lineal scanning systems.

News from GreCon Dimter

The OptiCut 204, manufactured by GreCon Dimter, features simple handling with a number of mechanization options, such as an uncomplicated operator control panel for input of production data in the optimizing computer, exact logging of production data, controlled stock warehousing, checking and evaluating timber grades comparison of suppliers and quick adjustment to individual specifications. Operators can concentrate on marking unexploitable waste pieces and grading timber using the set marking code. The rest is done by the optimizing computer, which features software that evaluates the marks for optimum yield. The optimization program enables processing of eight different timber groups, eight grades and 200 fixed lengths per grade.

The drive motor and saw rocker arm guarantee an average of 12,000 running metres and more per shift, claims the manufacturer. The operator can select the desired sorting method according to length, grades or special orders. The length of the sorting station and the number of ejectors can be selected as required, due to the modular construction of the line.

The Supra fingerjointing system processes both soft and hardwoods with a minimum ingoing length of 180mm.

WSM Horizontal Slab Hog West Salem Machinery Co.'s newest addition to their line of horizontally fed wood and bark hogs has special features for use in slab wood applications. The WSM Model 3232BH provides a 32"-diameter cutting circle for improved processing of large piece-size material. Hooked-tooth hammers provide excellent cutting action and superior product sizing with less maintenance, claims WSM. Modular sizing screens allow for optimum product sizing for mulch, animal bedding or boiler fuel materials. In addition, the WSM Model 3232BH comes with WSM's heavy-duty powered feed mechanism with the new large-diameter feed roll for a metered, consistent feed to the hog.

New Filter System The CP 2002 filter system for filing rooms and saw shops extends coolant life' While reducing waste and features sub-Micron cleaning and filter life of up to three months According to its manufacturers, the system provides for faster speeds, less burning and longer tool life, and handles tramp oils and greases, offering a payback time as short as six months. The filter system is designed for tooling and other light to medium grinding applications, as well as precision machining, high-speed machining and general machining applications.

Grooving Precision Griffiths & Beerens (GB) have developed custom-designed, computer-controlled grinding machines. Computer-guided automation reduces handling and increases grinding speed, resulting in faster production and tighter tolerances, reports the Company. GB bars also benefit from the way they are cut; grinding allows the use of harder, stronger materials, which means the bar and its rails are more durable. GB's precision grinding process also produces a radius at the bottom of the groove, which is more desirable because it adds thickness and strength to the base of the rails and helps prevent problems, such as flaring, cracking and breaking.
