TECH UPDATE - Primary Breakdown Equipment

USNR - Soderhamn Eriksson

Vision Tilt from USNR-Soderhamn Eriksson improves lumber sizes as well as saw blade service life, according to the company. The patent-pending system controls saw blades by actively tilting the band wheels, and it can easily be installed on new or existing band saws.

The equipment includes a camera placed on the return side of the saw blade, level with the upper band wheel’s centre. The camera monitors saw tooth position in relation to the band wheel’s front edge. Incorrectly aligned saw blades generate cracks in the tooth base over time and wear on the band wheels and saw guides. Vision Tilt actively corrects the saw’s position on the band wheel, which minimizes wear and improves sawing accuracy.

Vision Tilt also includes a PLC with software for monitoring and adjustment. The intelligent control system alerts operators to faults such as saws showing signs of imminent rupture.

Linck

Linck says it can help turn client sawmills into revenue generating machines due to its decades of experience in both conception and manufacturing. The Linck profiling lines have reached a new level of optimum lumber quality combined with significantly lower production costs, says the company.

When using profiling technology, the traditional edging installations are no longer needed, so customers can use capital for other purposes instead of buying spares. Companies can earn more, says Linck, by running a single operator Linck profiling line with high achievement and availability. 

Linck profiling technology produces optimized sideboards on the fly, directly at the cant with high speed and without any bottlenecks. Linck technology also offers no optimization limits, as the state-of-the-art Linck VPM profiling unit is able to work with the curve or to perform diagonal profiling along the cant.

TS Manufacturing

Sawmills around the world are using TS Manufacturing systems for primary breakdown because of their inherent ruggedness, reliability and optimized precision, says the company. Once installed, TS carriages, c-frames and bandsaws don’t quit, according to the company, as the low maintenance equipment designs and optimized scanning and software systems will manage the high precision that customer mills demand for increased volume and profits.

TS Manufacturing makes a comprehensive line of primary breakdown and log merchandising systems. It makes the step feeders, kickers, slasher saws, debarkers and sharp chains customers need to get logs into the mill. Once inside, the company’s optimized carriages, headrigs and c-frame systems accurately assess and orient logs for perfect cuts, ensuring that downstream resaws and edgers get maximum volume, says the company.

TS Manufacturing’s original designs are backed by its Intercross Support Staff (ISS), consisting of in-house engineers, installers and now, an in-house PLC/electronic controls team.

Optimil

Optimil’s recent focus has been to address chip and dust containment on its chipping and sawing machines.

The new chipping sections have increased the head diameters and the size of the chip chutes. Optimil has also reconfigured the chip chutes to create a better chip flow, having less transitions and thereby less places for the chips to hit and to break up, creating dust. Optimil has several of the new designed machines out in the field and the results have been very favorable, says the company. The new guards help to promote safety by preventing debris from exiting into the workplace area.

This focus includes dust containment on saw boxes and bandmills, while not compromising the maintenance process or safety.

Comact

For well over a decade, profiling heads such as the DDM have been an integral component of Comact primary breakdown systems, as well as profiling heads such as the TBL3 for secondary breakdown systems.

To meet the needs of its clients aiming to operate ever more productive and profitable sawmills, Comact has improved its product offerings over the last few years. In fact, the company says that it has delivered various mill projects where profiling heads have been integrated into the twin canter at the primary breakdown to profile sideboards, and thus limit handling, not to mention relieve existing edgers.

Profiling allows for reduced cutting height of the twin since logs have already been profiled. Due to the fact that saws have less material to cut through, it’s possible to increase edging speed by up to 25 per cent, says Comact. For a sawmill seeking to increase its throughput, this is a sizable advantage, besides getting rid of typical edger bottlenecks. Thanks to the integration of profiling heads both at primary and secondary breakdown, Comact has managed to offer productive, profitable solutions specifically adapted to the needs of its clients, says the company.

HewSaw

HewSaw has been producing primary breakdown equipment for over half-a-century and today the Finland-based company manufactures and supplies equipment capable of processing logs from 3.5” up to 21.5” in diameter.

Sophisticated scanning, optimization and automation packages ensure HewSaw customers achieve maximum yield from each log, all while operating safely and efficiently with an emphasis on minimizing operational staff.

Today’s HewSaws are custom-built with top quality materials and to precise tolerances, says the company. From single pass machines to multiple unit sawlines, HewSaw says that it can provide solutions for all of its customers’ primary breakdown requirements. The company’s multi-unit sawlines can deliver up to eight edged sideboards from each log, eliminating the need for downstream edgers.

Over 400 HewSaws have been delivered worldwide and the company currently has HewSaws operating in over 30 countries on five continents.

INOTECH

Inotech describes its Canadian-made one pass sawing line as the most affordable one pass canter on the market, with over a decade of development and testing.

It can produce square blocks from 2 X 2 to 6 X 6, from logs from 2.5” to 10” diameter.

It is designed with full scan and set operation, with a choice of scanners, and has an integrated saw box with up to three saws.

This sawmill can be installed in the tightest spaces, and its 2-D scanner can be easily configured for a variety of production, says the company. An optional 3-D scanner with log rotation is available. It offers high speed production of up to 600 ft/min.

Lico Machinery

Lico offers a wide range of ripping solutions for mid-range production, meeting the most demanding requirements, says the company. Its ripping systems will help customers maximize yield and productivity at the sawmill. A single system can be designed to produce from 20,000 board feet to 90,000 board feet (4/4) per shift with ripping yields up to 93 per cent.

Lico Machinery’s ripping systems can be used by manufacturers producing flooring, molding, components, windows and more.

Standard features include ripsaw feed speed up to 525 fpm, thin kerf moving blades, with every board having its own unique sawing pattern

Options include single or dual scanning; a range of scanning solutions, from single point width measurement to complete 3D scanning; automatic edging removal; automatic board flipping; text printing or color marking; bow busting; curve sawing; and very high rip width accuracy.
