Safety first

Machinery safety is the basis of having a safe working environment.


SAFETY IS ONE OF the key factors in having a successful industrial panel producing business today. Machinery safety is the basis of having a safe working environment. No safety rules or safety practices can replace modern automated guarding and safety solutions integrated to machinery. By applying the latest safety standards (like ISO 12100), Raute sets the goal that customer employees always get home healthy. As an active member of the Observing Committee (K114) of European Committee for Standardization CEN/TC 114 – Safety of Machinery, Raute is one step ahead when it comes to new safety standards and safety legislation.

To apply safety standards/safety legislation, use of full area guarding with fencing days is a must. The best results are achieved when the latest solutions of safety automation, safety logic controllers and safety drives are combined with account usability and efficient production. By using Raute machinery, those aspects are always integrated. For example, full area guarding, based on fencing surrounding the line and interlocking guards and photo sensitive safety equipments, ensures that access to machinery always means a safety stop – but only in that part of machinery where it is needed. In most cases, other parts of the line can continue production.


How to enhance the drying process

Improper drying is the cause of most damages and veneer losses in plywood production. It is the process through which quality is made and cannot be improved afterwards. During the drying process, the moisture inside wood cells is evaporated in the shortest possible time and with the minimum use of energy. It may sound simple, but production managers struggle with splits, over dried veneers, jams and stops in the process, as well as the need for re-drying and having to deal with broken veneers on a daily basis. Luckily, proper technology can make this process much more predictable.


HOW TO DRY VENEER efficiently to desired moisture and maintain quality and elastic properties for further processes? This is the question the most successfull plywood and LVL producers are paying attention to. The answer lies in focusing more on the input material and combining that information to drying functions and controls in a smart way.

RAW MATERIAL CHALLENGES DRYING

As every producer knows, wood material has a great deal of variation in moisture and stiffness, depending on the log size, ground, time and place of growth.

Variation also occurs inside every block, depending on which part of the block the veneer is peeled.

As raw material properties continuously change, the drying process must also adapt accordingly. Unfortunately, most of the drying solutions on the market simply don’t have any tools for that.

When quality and efficiency matters, the right solution is an intuitive drying process that automatically adjusts the speed, temperature and moisture for a given material batch with minimized energy usage.

ANALYZERS BRING THE PROCESS TO THE NEXT LEVEL

The Drying ProcessTaking advantage of long experience with dryers, Raute, together with Mecano, has developed accurate veneer analyzers. The most advanced mills have earlier first adapted greyscale VDA and DMA brush meter analyzers, then upgrading and ending up with the latest G5 technology.

Mecano MVA was the first analyzer that made previously impossible low moisture analyzing a reality – setting a new standard for moisture grading. Mecano MVA-G is the game changer when the highest quality, recovery and smooth operation are required. When installed in a peeling line before clipping, it offers remarkable savings by accurately separating wet and dry veneer scanning through the veneer, instead of just the surface. In addition to accurate analyzes in low moistures, MVA finds uneven moisturized zebra veneer that causes great losses in drying. When spotted already in the peeling line, zebra veneer can be dried separately in different drying conditions.

The latest addition to Raute’s product family is Metriguard Veneer Tester DME 2805, which is the industry standard in the evaluation of veneer suitability for structural uses. Together with the VDA it brings the entire grading process up to a new level by enabling even a more efficient usage of raw material.

PROFITS BY PROPER DRYING

You need valid information to be able to improve the process. Efficient drying is possible when moisture and veneer properties are properly measured and gathered data utilized in the drying line. Drying will always be one of the most challenging processes in plywood and LVL production. However, with the right knowhow and tools, challenges can be transformed into a competitive advantage!

MECANO MVA-G IS A GAME CHANGER.

A Finnish company developed a veneer bike

Wood-based products are now strongly experiencing a new era of popularity and new applications are found, for instance, in design.


THE BEAUTY and individual structure of wood is not the only reason that enhances the use of wood. Important factors are also the consumers’ interest in renewable materials and in endeavours to make ecological and sustainable choices. A good example of this is the Wiilubike – a bicycle with a body made of wood.

Wiilubike was developed by the Finnish Wood Innovations Finland Oy.

The starting point for the design of the wooden bike was to emphasize the possibilities of the utilisation of wood in products where it is traditionally not known to be used.

”A wooden bike as a thought felt sufficiently technical and outstanding, compared, for example, with traditional furniture”, says Ilari Alaruka, the founder of the company.

The design of Wiilubike is functional and simple and it really stands out. The bike was designed by means of 3D simulation. The style and initial prototypes and drawings were created directly from 3D files. The bodies of the production models are milled with a 5-shaft milling machine from a form-pressed blank, which guarantees a perfect fit of the metal and wooden components in the assembly. The manufacturing technique also enhances the manufacture of bodies of different sizes and shapes by changing the manufacturing tracks. Veneer of any species can be used for the face.

Raute New Applications
A Finnish company developed a veneer bike.

The business customers of Wiilubike are companies in the wood and forest industries, as well as companies, into whose values, operations and brands Wiilubike brings additional value for increased support and awareness. Some end user customers of Wiilubike wish to support the Finnish wood and forest industries, whereas others wish to communicate on the ecology. ”The owner of a Wiilubike is a brave and open-minded optimist, who lives to the full every moment”.

In terms of the material, strict requirements are set on the veneer quality. The veneer shall be strong and free of knots. The torsional rigidity required of the bike body is attained with carefully made glue lines and the correct grain directions. Nevertheless, the wooden body retains an appropriate elasticity and dampens vibrations on uneven ground without loosing its riding properties.

The veneer is peeled from birch blocks by Koskisen Oy with Raute lathes. The veneer is processed and form pressed into parts for the bike body. Other components are supplied by players in the field around the world, and assistance for the assembly is provided by the Finnish bike factory Salon Polkupyörätehdas.
