Abstract

A rotary bushhammering apparatus comprises a head (26, 119) having a hub (15, 115) connected for rotation to a rotary shaft (16, 112). The head (26, 119) in turn comprises a plurality of freely rotating rollers (12, 117) the axis of which is disposed radially to the rotation axis of the head, each roller having radially projecting points (14, 118) on its peripheral surface, so that on rotation of the head (26, 119), it is driven to roll on a surface to be worked, the points thus scratching said surface to be worked. A mass (20, 121) weighing on the rollers (12, 117) is supported between the rotary shaft (16, 112) and head (26, 119) so that said rollers (12,117) can exert pressure against the surface to be worked, the mass (20, 121) being prevented from rotating with the head (26, 119). Advantageously, the head (26) can be connected to the rotary shaft (16) by interposition of an articulated joint (25) enabling the free inclination of the head (26) rotation plane with respect to the rotation axis of the shaft (16). In this way, the working of the curved surfaces is permitted. <IMAGE>
