FILLING BAGS OF FILM MATERIAL

摘要

THERE IS DESCRIBED A METHOD AND AN APPARATUS FOR FILLING CONTENTS INTO FILM BAGS (12) AND A PACKING ITEM THAT MAY BE USED THEREFOR. THE APPARATUS INCLUDES A FILLING STATION (34) INCLUDING A MANDREL (20) WHICH SUCCESSIVELY IS GUIDED INTO A CHANNEL-SHAPED OPENING RIM AREA (38) OF A CONTINUOUS WEB OF FILM BAG ITEMS (12). BAG OPENINGS (20) ARE COMMUNICATING WITH THE CHANNEL-SHAPED OPENING RIM AREA (38) AND ARE FILLED WITH FLUID MATERIAL VIA THE MANDREL (20), WHICH IN ITS CIRCUMFERENTIAL SURFACE HAS OPENINGS (42) THAT MAY BE ALIGNED WITH THE BAG OPENINGS (40). SQUEEZE MEANS (48) SQUEEZE CHANNEL-SHAPED OPENING RIM AREAS (38) AROUND THE MANDREL SO THAT A WELL-DEFINED VOLUME MAY BE FILLED INTO EACH INDIVIDUAL BAG WHICH IS ALIGNED WITH ONE OR MORE OPENINGS (42) BETWEEN SUCCEEDING SQUEEZING MEANS (48). THE MANDREL ALSO PROVIDES A FIRM AND WELL-DEFINED CARRIER ENGAGEMENT FOR THE BAG WEB DURING FILING AND SUBSEQUENT WELDING OF THE BAGS (12).
