A slat exchange system in thermo-welding machines having cells or alveolar cavities, a chain conveyor, and an IT management apparatus, said system comprising:

• at least one fixed slat part permanently connected to said chain conveyor;
• at least one removable slat part having one or more shapes/profiles and adapted to be reversibly hooked to and unhooked from said fixed slat part in order to be exchanged with another removable slat part having different shapes/profiles and/or for maintenance reasons;
• wherein said removable slat part is provided with a symmetric groove arranged in central position within a wall thickness of said removable slat part;
• at least one hooking and unhooking mechanism installed on said fixed slat part, adapted for allowing hooking and unhooking of said removable slat part in order to promote a swift exchange/replacement of the removable slat part.
