Rotating emery strips with suction by means of a reduced pressure, in three stages, of dust thus generated

摘要

a carteggiatrice disc with integral means for suction of dust produced using a special pluristadio jet compressed air associated with the handle of the machine for extracting the polreal produced in the work area and to convogliarle through a flexible hose to a zone of dust precipitation.in a preferred form of execution, the compressed air is injected to the same compressed air effluent from an engine with compressed air, which leads to rotation of the disc.a valve operated by an external lever has the run of bolt adjustable via a knob or cap to regulate the speed of rotation when the disk when the control leverthe valve is lowered by the operator.the stadiatura of intake system for jet produces a great effect and a great aspiration aspiring regularity of the changing conditions determined by the manoeuvres carried out bythe carteggiatrice.
