Abstract

Sanding device, perfected; which is constituted from a metallic frame provided inferiorly with self-orienting wheels for its transfer, and externally from a board or table through which the sander belt mounted endlessly between two rollers integral with vertical trees and parallel to each other emerges loosely; essentially it is characterized in that said vertical shafts are mounted on bearings stiffened to a plate which, in turn, comprises an electric drive motor of the aforementioned sander belt, the plate in question being made possible by vertical alternative movements through materialized guides. In the metal frame itself; this movement of the plate being regulated by virtue of its relation to a connecting rod eccentrically of a diode connected to the output shaft of a motor-reducer anchored to the base of the aforesaid metallic frame, contributing with said crank for the descending movement of the plate uncontrapese of antagonistic action with respect to the gravitational effect of the electric drive motor of the sander belt; it being provided that at least one of the vertical shafts extends upwards to receive the coupling of an auxiliary mill; and that the board or table adopts various degrees of inclination with respect to the permanent horizontality of the metal frame and of the sander band, in combination with a tensioner thereof, to modify the angle of incidence thereof on the material to be worked.
