Abstract

A device for the packaging of powder, granulates, slurries and viscous materials in a tubular film which is formed from an endless web of film by a forming shoulder into a tube which is filled by means of a filling pipe with the material to be packaged and subdivided at intervals by transverse closures which are formed by a clamp which is moved against the tubular film transverse to the direction of film movement by two cooperating gathering irons which are moved against the tubular film from opposite sides, to gather the tubular film and therby form the transverse closure. In order, despite simple construction, to make considerably higher output possible and at the same time avoid limitations with respect to the minimum length of the tubular bags, two turret disks, driven with uniform rotation in opposite directions to each other, are arranged below the filling pipe in the direction of movement of the tubular film, each of said disks bearing at least one of the gathering irons which cooperate in pairs with each other and which are supported for rotation on the turret disks in such a manner that they are always directed transverse to the direction of movement of the tubular film.
