DOSAGE DEVICE FOR EXTRUDING A BICOMPONENT OR MONOCOMPONENT SEALANT
A dosage device for extruding a bicomponent or a monocomponent sealant, particularly for an automatic machine for sealing a perimetric edge of an insulating glazing unit constituted by at least two glass sheets and by at least one spacer frame, having a finite width, is arranged proximate to the perimeter at a finite distance from the margin of the glass sheets, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the sealant, which can be activated alternately, in a first feeding step and in a third feeding step, so that one of them provides flow continuity to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activatable, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.
