Assembly for producing paper packaging for fast food, particularly comprising deep coated pleats

Assembly for producing fast food packaging for sandwiches or loose products, using a pleated element made from a paper strip (14) having a width (Wpp) and coated on one side with polypropylene and/or polyethylene, comprised of deep coated pleats parallel to one another and fixed at their ends, this production assembly being comprised of a paper feed module (5) feeding a pleating module (6), said pleating module (6) being provided with a pleat forming mechanism and a pleat coating mechanism pleating the paper strip (14) coming from a reel (3) of the paper feed module (5) to obtain a free pleated paper strip (119), the pleating module (6) being followed by a unit (7) for fixing the end of the pleats producing a pleated paper strip (31), which then penetrates into a finishing unit (8, 118, 42, 53, 88, 96, 128), characterized in that

• the folding module comprises a preforming wheel (20) and a preforming counter-wheel (21) forming the pleat-forming mechanism, a bar wheel (22), a pleat grouping wheel (23) and a pleat coating wheel (24) forming the pleat coating mechanism,
• the unit (7) for fixing the end of the pleats and the finishing unit are in the form of separate modules, the finishing module (8, 118, 42, 53, 88, 96, 128) being specific to each type of packaging manufactured, thereby producing a completed packaging container (115),
• the production assembly includes a collecting and processing module (9) collecting the completed packaging (115) of the finishing module (8, 118, 42, 53, 88, 96, 128).
