PACKAGING MACHINE FOR LONG FOOD PASTA OR SIMILAR PRODUCTS WITH FORMATION OF SINGLE PACKAGES OF PASTA OR OTHER, EQUIPPED WITH TRANSVERSE FLAP CLOSING

摘要

In a packaging machine for long food pasta or similar products a motorized input conveyor belt (4) and a motorized output conveyor belt (6) are comprised which are driven by respective independently adjustable moving groups (17, 19). The two belts (4, 6) are aligned with one another in a longitudinal direction so as to form a single advancement path for a tubular wrapping (47) filled with successive doses of product (48) and are also longitudinally spaced from one another so as to define an intermediate space wherein a transverse welding and cutting group (27) operates which is supported by a structure (41) horizontally displaceable with alternated movement along said advancement path of the wrapping (47). The structure (41) also includes a support (14) holding an output roll (9) of said input conveyor belt (4) and an input roll (21) of said output conveyor belt (6) at a fixed distance so as to confer said rolls (9, 21) an alternated horizontal movement coinciding with that of said welding and cutting group (27).
