A linear guide carriage (6) actuated by mechanical or electrical energy allows the rotary cutting tool (7) and a glue depositing system (8) to be moved (pressurized hot-melt glue extrusion nozzle ).
Un aligneur (9) composée de doigts métalliques ou plastiques alignés et parallèles aux mâchoires (2) + (3) et (4) + (5) sert à la fois ; de butée pour le positionnement du placage (12) et en fonction de la section ou du diamètre des doigts détermine le volume de matière qu'enlèvera l'outil de coupe (7), l'aligneur (9) commandé pour son déplacement vertical par un actionneur pneumatique, électrique ou hydraulique se rétracte sous le niveau des mâchoires (2) et (4). An aligner (9) composed of metallic or plastic fingers aligned and parallel to the jaws (2) + (3) and (4) + (5) is used at the same time; stop for positioning the veneer (12) and depending on the section or the diameter of the fingers determines the volume of material that will be removed by the cutting tool (7), the aligner (9) controlled for its vertical displacement by a pneumatic, electric or hydraulic actuator retracts below the level of the jaws (2) and (4).
Le transport des placages (12) est assuré par deux transporteurs à bandes, tapis ou chaînes, motorisés (10) et (11) de part et d'autre des mâchoires de références (2) et (4). The veneers (12) are transported by two conveyor belts, belts or chains, motorized (10) and (11) on either side of the reference jaws (2) and (4).
