    摘要: A tubular bag machine has between a filling tube and a shaping tube at least two sealing elements, which divide an annular space, formed by the filling tube and shaping tube, into a feed channel and a suction-removal channel. The two channels are connected to a suction device with a filter by connecting lines. The design and arrangement of the sealing elements produce a closed circuit for the air or inert gas used for dust removal.

    摘要: A bag evacuating and closing apparatus having two opposing jaws which face ends that move toward one another. The jaws encompass a top closure of a bag package to be sealed. The jaws have hollow spaces open toward one another which are surrounded by frames with sealing jaws disposed in the hollow spaces; the hollow spaces form a chamber that receives the top closure of the bag package. A sealing rib protrudes from one face end of the two frames and is interrupted in a middle region of the frame part at which the closure fold protrudes between the jaws. In this region, suction openings are disposed in the frame parts of both jaws; these suction openings pull two walls of the top closure tightly against the frame parts. After the top closure of the bag package has been tightly encompassed, air is extracted from the bag package by a vacuum, and subsequently, the top closure of the package is tightly sealed by the sealing jaws which form a sealing seam to close the upper end of the bag.

    摘要: Method of manufacturing a filled packaging container comprising the steps of forming a bag on a mandrel, connecting a seam provided in a formed bag, forming a hole on an upper side of the bag and inserting a valve into the hole to provide an air pressure release after filling the container with a material. Two opposite edges of the valve are formed with two flexible portions made of foil. A sealing fluid is applied in the channel to provide a fluid film to connect the foil portions.

    摘要: A package for coffee or the like of tubular configuration having an outer sleeve and a tubular reinforcing member within the sleeve. A tear strip is located between the sleeve and the reinforcing member at the upper end of the package to provide a common and flush end with the reinforcing member. The narrow strip peripherally surrounds the reinforcing member and projects outwardly from the package. The package has a fin-seal closure.

    摘要: An overpressure valve for a packaging container which includes a base plate with a central valve hole that coincides with a hole in a wall of the container and a valve diaphragm. The valve diaphragm covers the valve hole and the adjoining zones and includes two parallel peripheral zones which form a channel along an adhesive-free middle zone. To keep the opening pressure of the overpressure valve slight and to simplify the manufacture of the tool for the valve hole, the valve hole is formed of two intersecting circular holes which extend longitudinally of the adhesive-free middle zone of the valve diaphragm.

    摘要: For sealing off overpressure valves of packaging containers, a small quantity of liquid sealant is introduced into a valve. To check whether such valve has been equipped with sealant, the sealant is heated, prior to introduction into the valve, to a temperature that is elevated compared with ambient temperature. After that the valve is checked for a temperature difference with a heat sensor, which causes valves not equipped with sealant to be rejected. The sealant is heated immediately prior to its application to a valve, in a nozzle delivering it.
