Two parallel lines 13, 14 of six-packs 10 are continuously delivered to a stop device 38 and starting conveyor 19 disposed above a stationary platform 24 by a belt conveyor 15. The stop device and starting conveyor carry downwardly depending pins 39, 40; 22, 23 that are synchronously driven both transverse to and in the transport direction. These pins separate the six-packs into groups 18 of two and accelerate them to an intermediate conveyor 20 running at the same speed and comprising endless chains 30 mounting transverse bars 29 that pass through opening slots 26, 28 at the beginning and end of the conveyor 20 and engage the six-pack groups at their rear ends. The groups converge along the conveyor 20, at the end of which they are engaged by an end conveyor 21 in the form of a slide member 31 coupled to a pantograph linkage and driven by a chain drive 33. The slide member has front and rear arms 41, 32 that engage the converged six-pack groups 18 and accelerate them onto a partially folded carton blank 11, where they are halted in a properly registered position by a yieldable end stop member 36. The loaded blank is then removed transverse to the feed direction for further wrapping, and a fresh blank is fed into the loading station. The spaced separation of the groups and their accelerated movement by the end conveyor allows time for the removal and replacement of the carton blanks, and the return of the slide member to engage a fresh group of six-packs.
