Tweddle Engineering Launch New Incising Technologies

From the middle of April, Tweddle Engineering, working in partnership with Lonza Wood Protection, can offer timber treatment and sawmill companies a choice of innovative incising technologies for both square sawn and round ground contact timbers.

The EXCALIBUR (for square sawn timbers) and SIDEWINDER (for timber rounds) incising machines deliver focused, cost effective and ‘real life’ solutions to the particular requirements identified by the timber trade.

Both machines are designed with a compact footprint and a have robust construction from quality CE marked components to withstand typical sawmill environments.

Common commodity sizes of sawn and round timbers are all catered for with options to incise full length or part length of posts.  Typical lead-times from order to delivery and installation will be just 3 – 5 weeks.

Tweddle Engineering has been designing and manufacturing large scale handling and processing equipment for over 25 years, including significant projects within the timber treatment industry. Derek Tweddle explained this latest development into incising technologies. ‘Surface incising of ground contact timbers prior to the industrial application of high pressure preservative treatments is increasingly being recognised as a preferred method to help achieve an improved and more consistent penetration of wood preservative into the timber, particularly through more resistant heartwood zones of the timber component.’

‘Working with Lonza has allowed us to design and deliver these focused new technologies to meet the specific needs identified by their customers.’

‘Both machines deliver a consistent incising pattern through an advanced head control using hydraulic cylinders rather than simple spring systems. The incising pattern is aesthetically pleasing and depth consistent, even across surface knots. The self-cleaning steel blades are easy to access and speedy to replace when required and incorporate a clever design of blade spacer allowing a flexibility to the incising pattern.’

‘Within the machines we use only CE marked, off the shelf components that deliver real performance yet provide low cost maintenance when required. There is a minimum of moving parts and we have made sure that there is easy access for any maintenance work’.

‘Immediate demand has been for the improved incising for sawn timbers and EXCALIBUR is now available. The machine has a footprint of just 1.55 metres x 2.30 metres and can four face incise in a single pass any sawn timber length in standard sizes from 22mm up to 225mm at a speed of 60 metres per minute. If required, larger dimension timbers can be catered for in the machine design and manufacture. The EXCALIBUR technology allows for a quick and simple change between component sizes.’

‘The design of SIDEWINDER for incising timber rounds is revolutionary and will bring totally new ideas and solutions to this previously difficult task of achieving a consistent and effective incising result. SIDEWINDER incorporates several innovative design features with patents pending.’

‘Our objective is always to produce and deliver high quality equipment which will stand the test of time and hard work, representing excellent value for money. Both EXCALIBUR and SIDEWINDER incising technologies have been designed to do just that.’

Both new technologies can be demonstrated to interested parties from mid April at Tweddle Engineering in Cumbria. To arrange a viewing contact Tweddle directly or your Lonza regional sales manager.
