Abstract:
A floor sander (1) with wheels for hand operated displacement along a surface to be treated, said sander (1) comprising a motor-driven cylindrical body having an outer surface comprising a casing (12) with a grinding agent on its outside surface;characterized in that the cylindrical body comprises a first cylindrical tube (2) and a second cylindrical tube of elastic material around the outer surface of the first cylindrical tube, said second tube having an inner surface in contact with the outer surface of the first tube (2), said second tube comprising a number of units (9) which are equal long, homogeneous and having a cross section like a frustrum of a sector, said first tube including a number of radial flanges extending along the whole first tube, each said flange being arranged between two adjacent surfaces of two said units (9) each radial flange including at an upper end two transversal bulges which are directed in two different directions and extending along the length of the flange, each unit (9) having a longitudinal and inwardly directed groove at each side surface such that the units create a cylindrical body during influence of a centrifugal force.
