<p>A chain conveyor for heat-shrinkage environments like a heat-shrinkage tunnel, said tunnel (10) including a tunnel-shaped chamber (11) located on a base framework (12), a ventilation device (14', 14") and heating elements (15) said conveyor being placed in the lower part of said tunnel-shaped chamber (11) and adapted for receiving the articles (17) placed into a film (18) which must be heat-shrunk on said articles. According to the invention, said conveyor includes a chain (19) that slides engaged, at least partially, on the teeth of a series of gearwheels (20) which are integral with the extremity of each one of an identical series of rollers (21), rotating on their own axes integral with said framework (12). The chain (19), forming a closed ring, is put into motion by a ratio-motor (23), placed in said framework (12). <IMAGE></p> |
