    摘要： The present disclosure provides an apparatus for forming a stream of individual packets, comprising a folder arranged to form a tubular web structure, a feeder arranged to feed the formed tubular web structure to a nip; a first rotor comprising a first sealing jaw and a knife, a second rotor comprising a second sealing jaw and an anvil, the sealing jaws, the knife and anvil rotating into opposing relation at the nip so as to form a severed, completed packet beyond the nip. The apparatus includes an open ended packet catcher adjacent the first and second rotors, which is arranged to catch the severed, completed packets beyond the nip whereby a stream of packets is established. The packet catcher includes a stripper disposed in a proximal location to at least one of the anvil, the knife and the sealing jaws when the anvil, the knife and/or the sealing jaws are rotated beyond the nip, whereby, should a completed packet stick to any of the anvil, the knife and/or the sealing jaws, the stripper is operative to free the stuck packet from the anvil, the knife and/or the sealing jaw. The present disclosure provides a fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers, the fin sealer being further arranged to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller. A cooling system is also provided, which is operative upon one of the rotors of a cut and seal station.
