Filling tube for a filling machine preferably designed to fill valve bags.

摘要

The invention relates to a filling tube (10) having an annular chamber (15) communicating with an air line (16) for filling valve bags on a filling machine. BR/ The outlet opening (13) of the filling tube (10) is limited by a closure ring (14) of filter material, surrounded by the annular chamber (15). At the completion of the filling operation, the closure ring (14) is connected to the vacuum and, if necessary, it receives a jet of compressed air after placing an empty bag. This results in a more precise filling by weight, and a dust-off. / P
