Abstract: A sanding machine for sanding the surfaces of work pieces placed upon a conveyor that transports the work pieces along a first direction towards and beneath a sanding head. The sanding head comprises a sanding belt entrained around an upper tension roller and a lower contact roller. The tension roller and contact roller are provided with a single translational orbital movement by a pair of eccentric shafts operatively connected thereto and rotatably driven by an operatively connected motor. At least one of the upper tension roller and lower contact roller is also driven by an operatively connected motor so as to provide the endless rotation of the sanding belt around the upper tension roller and lower contact roller. In this fashion, the sanding belt is provided with two contemporaneous superimposed movements consisting of rotational movement about the tension roller and contact roller and a single orbital translational movement imparted by the rotating pair of eccentric shafts. The resulting sanding pattern is homogeneous and renders scratches normally created by the endlessly rotating sanding belt substantially unnoticeable.

Abstract: The present invention consists in employing conveyors and/or pushers in order to permit movable planes (7,110) to be advanced along bearing guides (1, 102) showing a quadrilateral shape. The advancing motion of the movable planes (7, 110) is caused by several devices which are housed in seats, suitably profiled, of the guides (1, 102). These devices are mounted on a peripheral chain line (3, 104). According to a first embodiment, the aforesaid devices are provided with a series of small bars (5) which are mounted on the chain (3) and supports magnetic elements (4) dragging metallic discs (6) applied under sliding planes (7). According to a second embodiment, the chain line (104) supports a series of plates (106) which are provided with pushers (108) working in contrast with a spring and pushing vertical stirrups (111) which are provided under the sliding planes (110).
