<p>A method and device (1) for forming groups (10) of products (3), whereby a substantially continuous input succession (2) of products (3) is fed to an input (6) of an endless conveyor (13), which has a conveying branch (14) and a return branch (15) extending between the input (6) and an output (8), and which has a variable speed drive member (25) operated to impart a variable speed to the conveyor (13) at the input (6), and to generate, along the conveying branch (14), a succession of equally spaced on-line gaps (11) defining a succession of groups (10) of products (3); the conveying and return branches (14, 15) are both engaged by a powered compensating device (27) for varying the lengths of the conveying and return branches (14, 15) in complementary manner, so as to maintain a constant speed of the conveyor (13) at the output (8) and compensate for any gaps in the input succession (2). <IMAGE></p> |
