Manufacture

Veneer Veneer The first manufacturing step is to place logs ( logs ) , so as to obtain thin thickness of veneer sheets controlled and scheduled as a function of two factors:
• the quality of the log
• the requirements in terms of control
The peeling process is the result of a particularly effective pair : + technology intelligence human . Two widths veneers are produced in anticipation of the composition " cross over " of Future panel. Each reel is driven by a " driver reel " that controls smooth running of the operation and makes adjustments necessary for a high level of quality.
Preparation Preparation The ridge of wood is then prepared for the veneer : made ​​size, debarked , possibly set the round . Depending on the characteristics of gasoline, it can also be steamed .
Logistics and supply Logistics and supply Once the collected logs, they are fed to the processing site . A stock buffer " is formed , and is the subject of a first sorting according to quality logs. Managed by a logistician , this stock has the function of regulating the supply, quantitatively and Qualitative : The manufacturer can thus meet the constantly commands.
Trimming Trimming The veneer sheets " fresh " are set to the dimensions by trimming ( operation carried out with high accuracy to optimize the material ) and then dried. During this operation , a camera and an image analyzer allow the fault to obtain a product of high mechanical and visual qualities .
Gluing and composition Gluing and composition The veneer sheets are sorted and classified , usually manually : they will be used in facings ( face ) , against in - facings ( cons -face ) or inner plies , according to their aesthetic quality . The veneer sheets are controlled by operators , before being sized and then superimposed " cross son " and arranged symmetrically on either side of the central fold ( or core ) , to obtain a balanced structure .
Pressing Pressing These stacks (wherein the number, type and thickness of the pleats varies the manufactured panel ) are then hot pressed . The heat ( around 160 ° C) is broadcast by both sides of the press during a perfectly controlled time as determined by the type of glue , the thickness of the folds and the thickness of the panels. This pressing "hot" allows the polymerization of the adhesive , providing a chemical and physical bond between the individual layers .
Focusing format and sanding Focusing format and sanding After pressing and cooling , the panels are délignés . This means they are set to the desired format, then sanded .
Marking and packaging Marking and packaging Plywood are then subject to rigorous marking. Each panel is identified by an ink marking on its edge in response to the regulation; packages are also marked (for display), and they have the CE label and a copy of the DoP . Once marked , the plywood is strictly conditioned for storage. The plywood panels are not fragile , but their storage requires minimal care.
Checks and tests Checks and tests The different stages of production are strictly controlled to firstly optimize processes and also to ensure product quality panels. The qualities and compliance with regulatory panels technical references ( Construction Product Regulations - CE ) or normative ( EN 636 , Plywood NF CTB- X , etc.) are subject to two types of controls : a self- directed by the manufacturer in its test laboratory and control (of twin tubes ) by an accredited third-party inspection body .
