Abstract
A calibration device for flat extruded sections comprises at least two flat calibration plates (10) parallel to one another at a distance apart such as to form a gap (1) through which an extruded section (11) can pass, each calibration plate comprising cooling means for cooling the plate and vacuum-forming means for creating a vacuum in the gap (1), the calibration device comprising air-intake means for introducing air into the gap (1), the air-intake means being designed to form air cushions or pads between the flat surfaces of the extruded section (11) and the flat surfaces of the calibration plates (10).
Claims10
A calibration device for a flat extruded section comprising two flat calibration plates (10) set parallel to one another at a distance apart such as to form a gap (1) through which an extruded section (11) can pass, each calibration plate comprising cooling means for cooling the plate and vacuum means for creating a vacuum in said gap (1), characterized in that said calibration device comprises air-intake means for introducing air into said gap (1), said air-intake means being designed to form air cushions between the flat surfaces of the extruded section (11) and the flat surfaces of the calibration plates (10).
