PACKAGING MACHINE FOR LONG PASTA OR SIMILAR PRODUCTS, FORMING SINGLE PACKAGES OF PASTA OR OTHER PRODUCTS, EQUIPPED WITH A TRANSVERSE FLAP CLOSURE

Abstract

In a packaging machine for long pasta or similar products, a motorized infeed conveyor belt (4) and a motorized outfeed conveyor belt (6) are driven by independently adjustable moving groups (17, 19). The two belts (4, 6) are aligned longitudinally to form a single path for a tubular package (47) filled with successive doses of product (48) and are also spaced longitudinally apart to define an intermediate space in which a transverse welding and cutting unit (27) operates. This unit is supported by a structure (41) that can be moved horizontally with an alternating motion along the said path of the package (47).The structure (41) also includes a support (14) supporting an output roller (9) of said input conveyor belt (4) and an input roller (21) of said output conveyor belt (6) at a fixed distance so as to cause said rollers (9, 21) to perform an alternating horizontal movement coinciding with that of said welding and cutting unit (27).
