ABSTRACT:
This invention relates to a machine for sealing parallelepiped boxes, which comprises a support surface for the boxes and a pair of closed-loop conveyor belts located around respective successions of rollers spaced apart along the feed direction of the boxes. According to the invention, the most downstream roller of each succession has a drive shaft rotatably supported by a slide, which can be adjustably spaced along a guide transverse to the feed direction of the boxes, on said shaft there being mounted a sprocket which cooperates with the analogous sprocket associated with the other conveyor belt, with a drive sprocket disposed in proximity to one side of said support surface and rotated by a motor, and with a chain tightening sprocket disposed in proximity to the other side of said support surface, by way of a chain which engages at its opposite ends with said sprockets associated with the conveyor belts.
