<p>The electric plastering machine which allows the projection of an adhesive pulverised substance such as plaster is provided with a projecting brush, with a helicoidal feed which is powered by an electric motor, fitted either with a push switch or an electric catch fitted into a revolver type handle, which allows better handling of the machine. An electronic speed variator can be incorporated into the operating switch so that an optimum quantity of material can be delivered as can a magnetic thermal cut out which protects the machine in case of a blockage. The switch can also be blocked on for tasks involving large surfaces.</p> |
