CANTERSPROFILERS

CONE-OMEGA

Profiling was common in the early Chip-N-Saw canter machines and in recent years profiling has made a comeback as a way of increasing profits by boosting productivity. Our profiler produces preedged sideboards that are trimmer ready. With almost no edger boards being generated, bottlenecks throughout the mill are reduced. When square edged, easy to handle boards are produced at the primary breakdown, overall mill flow improves, labor requirements are reduced and unnecessary downstream sorting and extra handling are eliminated.

We offer the profiler in twin and quad configurations. Designed for use with our sharp chain systems and any Chip-N-Saw style 4sided canter system, the profiler is placed between the top head and saw section modules. Only minimal modifications are required to add a profiler to an existing line, allowing profiled boards to be created anywhere on the side of the cant. During operation the chipping modules are inside the main frame and chips are completely contained. Chips are discharged out the bottom, making housekeeping a breeze.

Log faces are chipped, side boards profiled and our shifting quad sawbox takes off the side boards. Trimmer ready boards are separated from the center cant and head to the sorter. Center cants are transported downstream to either a VSA or VDA that can be supplied with a shifting timber pocket and a 5⁄4 bank that can shift below bedline until needed. An optional top and bottom profiler module can be added to the VSA/VDA that will eliminate the remaining 2-3% of edger boards that would have been created on the top.

Since the introduction of our profiler in 2017, we’ve installed 13 complete high speed profiling canter lines and retrofitted another line. We currently have two more systems in production for delivery in Q4 2023 and another in the queue for Q2 2024. Our quad profilers on our sharp chain lines feature adjustable inside board thickness. We have a sharp chain quad profiler as well as a profiling canter with 12 in. DAG that will both be commissioned in Q3 2023.

Mebor

Mebor presents its BM CDH log sawing lines. They are based on circular saw technology in combination with chipper canters. Log diameters range from 4 in. (100 mm) to 19.5 in. (500 mm), while the sawing lengths are adapted to the needs of each customer. It is equipped with a 3D scanner with operator controlled visual log turning or with automatic turning of logs and positioning of cants.

The new CDH-Q 500 circular saw for logs may use various blade diameters (1623.5 in. / 400-600 mm) to optimize kerf depending on the log diameters sawn. Cutting is distributed evenly between bottom and top shafts, allowing equal load on all the motors. The machine is able to cut 1/2/3 cants from the log, allowing a better recovery on certain cutting patterns. Cants are sawn by a double arbor VC DE multi rip saw. Variable speed of chipper canters allows a uniform chip size in relation to feeding speed. The main sawing line is controlled by one operator only.

Boards are edged by Mebor’s optimized FRC chipping edger that includes 1-3 additional circular rip saws.

The BM CDH line may also include automatic board stackers and all needed waste removal conveyors. Production rates of the lines range from 65,000 –140,000 BF/8h (approx. 250-500 m3 of log input), depending on the design and customer’s needs.

The recently installed line shown in the photo was designed for a minimum log length of 82 in. (2.1 m).
