PROCESSING ECOLOGY

PROCESSING ECOLOGY

We manufacture solid wood furniture using processing techniques which ensure environmental sustainability.

We are a member of Federlegno Arredo (Italian Federation of Wood, Cork, Furniture and Furnishing Industries). This association strives to give value to an industrial system based on high standards of quality in terms of both design and products, processing techniques with high technological content, safeguarding of the environment and the safety and security of the final customer.

TIMBER PROCESSING STAGES

  • Felling the pine trees

Felling the pine trees in specially-grown forests is the first stage in the production process of solid wood furniture. The trees are usually felled during the winter when the biological and vegetative activity of the trees is at a minimum. The trees for felling are selected on the basis of their age and size to safeguard the overall character of the forests. The operation to cut down the trees begins with assessment of the tree trunk to decide the direction of felling. Some of the branches are then cut from the tree to prevent them damaging surrounding flora when the tree falls. The tree is felled by cutting it at the base of the trunk using a chainsaw. The remaining branches are removed to prepare the trunk for shipping. The felling waste is broken up into small pieces directly on site using mobile machinery which loads the chips onto special lorries. The chips are then used to make chipboard. The bark is removed from the trunks at the timber depot allowing for efficient gathering of the bark which has a variety of uses including garden soil, as a raw material in the production of fertiliser and to make wood paste for industrial use.

  • Squaring of the trunks

The trunks are cut down four sides to square them after which they are divided into four parts by cutting them perpendicularly. Each of the four parts is then cut into planks from which smaller strips of wood are produced. This type of processing, known as quarter sawing, significantly reduces solid wood deformation and here’s why.

 

  • Structure of wood

The cells in wood are grouped together in long chains, known as fibres, which lie parallel and appear as different coloured stripes called veins. A knot on the other hand is simply the extension of a branch inside the trunk. Branches grow out from the middle, or pith, of the trunk and increase in size by adding a ring each year. This is the continuation of the corresponding rings of the tree trunk. The section of the branch inside the tree trunk has an irregular, tapered shape with the tip located in the pith. The fibres are positioned obliquely or at right angles to the trunk fibres and intertwine with them. In timber classification knots are assessed on the basis of size, shape, condition, colour and the bond with their seat. Thy are also a decorative feature on pine furniture.

 

 

  • Mechanical resistance of wood

The fibres making up the veins and knots in the wood play a critical role in the resistance of solid wood to stress, specifically warping and shrinking. When the stress is parallel to the prevalent direction of the fibres, the wood is extremely resistant, but if the stress is perpendicular to the fibres then the wood is very fragile. Furthermore the greatest amount of shrinkage occurs in the direction of the fibres. The pine timber is cut into strips using a process known as quarter sawing. This allows the strips to be glued together with counterposed veins to produce solid wood panels with excellent mechanical resistance. This gluing of the strips with counterposed veins, together with optimum drying of the wood, reduces the possibility of deformation to a minimum. The solid wood thus maintains its characteristic as a material that “breathes” to regulate the level of humidity in the furnished space.

Drying of pine 

Drying of solid pine is the processing stage in which the humidity is removed. The timber is placed in special dry, ventilated chambers also known as kilns. The air in the chambers is regulated using electrical heating systems to dry the wood. This process, performed with care, modifies the percentage of humidity in the pine wood to approximately 10-12%. This prevents the onset of warping, cracks and shrinkage of the panels making up the solid wood furniture.

 

The initial stages of solid wood processing are extremely important for the stability, sturdiness and durability of the solid wood furniture produced. For this reason we always select with care the solid wood used to manufacture our solid pine furniture to ensure the timber is of the highest quality.
