The present invention relates generally to pouches, and more particularly to a former to form pairs of dispenser pouches of the flexible three-sided sealed type. The former has a continuous foil channel and outer guide surfaces for a foil strip to be reshaped into a double tube, which enters the channel through a foil supply edge. A pair of form- and filling pipes are arranged in the channel, which has a back wall, two front walls having two form edges, and sidewalls that are adapted to the cross-section form of the filling pipes. The wedge-shaped form edges of the front walls delimit a slit in the lower part of the former. The back wall and the form edges of the front walls, proceeding from the foil supply edge and a section that converges in continuous direction between the front walls, are developed relative to one another and continually approaching until the end of the downwardly open slit.

Former for a packaging machine to form pairs of three side sealed pouches from packaging foil material

Tooling to form pairs of dispenser pouches

For pre-sterilizing a tubular bag packing machine to be operated under sterile conditions after the pre-sterilization phase, following the steam sterilization of the device metering the loading material and forming part of the machine, and of the forming pipe simultaneously serving as a filling pipe, the subsequent supply of sterile air to the meter, to the forming pipe and to the sterile chamber will be maintained. The longitudinally sealed tube of packing material formed on the forming pipe from the web of packing material is kept open underneath the opening of the sterile chamber in order to allow both the sterile air and the mixture of steam and sterilization agent conducted after pre-sterilization of the metering device into the sterile chamber to be discharged through the forming pipe and the tube of packing material open at the bottom.

Method for presterilizing a tubular pouch packing machine

A system of dividing an endless, wide multi-layered web of packing material into a plurality of individual webs of equal width and aseptically processing the individual webs comprises laser-cutting elongated slits into the endless wide multi-layered web at a distance corresponding to the width of the individual webs to produce the individual webs, the slits extending through all layers of the web except for a web layer remote from the laser, which is only notched at least at selected distances, whereby the notched remote web layer holds the individual webs together, then sterilizing the laser-cut multi-layered web in a sterilization station, and conveying the sterilized, laser-cut multi-layered web in a sterile chamber to a number of tube-shaping elements corresponding to the number of individual webs, the notched remote web layer being torn by the tube-shaping elements to separate the individual webs from each other.

Process and machine for dividing a multi-layered web utilized in aseptic packaging into a plurality of individual webs of equal width

An aseptically operating packing machine comprises a processing track with tools for treating a packing sheet arranged in a sterile chamber partially open to the atmosphere. Heated sterile air is blown through a sterile air filter, and a mixing nozzle is arranged downstream directly behind the filter within an ari channel terminating in the sterile chamber. The mixing nozzle is connected to a steam- and sterilizing agent-supply conduit and points downstream towards the sterile chamber. A tank in the sterilizing supply conduit holds the sterilizing agent under constant pressure, and a steam volume regulator is arranged in the steam supply conduit.

Aseptically working packaging machine and method for pre-sterilizing them

The invention is concerned with so-called sterile tunnels or tubes on aseptically operating packing machines. During operation, sterile air und during the pre-sterilizing phase, sterilizing fluid can flow through the telescopic tubular sealants provided on sterile tunnels or tubes of this type for the passage of mounting linkages of working elements disposed in the sterile chamber of the tunnel. To safely strike and destroy, during the pre-sterilization of the sterile tunnel, all germs contained in the labyrinth-type telescopic tubular sealant, discharge openings are provided in the upper part of the telescopic tubular sealant.

Process and plant for endless-cycle sterilization of sheet material utilized in aseptic packaging

An arrangement for sterilizing a flat web of a packing foil, which comprises a sterile casing having an inlet and an outlet, a rod-shaped UV radiator disposed in the sterile casing, a guide for guiding the web in a circular path around the UV radiator, the UV radiator being centrally arranged within the circular path and the guide being radially equidistantly spaced from the UV radiator, and deflecting elements at the inlet and the outlet of the sterile casing for deflecting the web into the circular path at the inlet and out of the circular path at the outlet.

Arrangement for degerming webs of packing foil

A dispensing valve comprises a housing defining a cylindrical cavity and feeding and discharge channels communicating with the cavity respectively through feeding and discharge ports. The cylindrical cavity has a diameter larger than the diameter of the feeding and discharge channels and the feeding and discharge ports. A pump intake and ejection port communicates with the cavity, the feeding and discharge channels being arranged substantially opposite the pump intake and ejection port. A closing part comprises an adjusting shaft sealing protruding into the housing and rotatable about an axis, and a cam carried by the adjusting shaft for rotation in the cavity, the cam being oriented toward one side with respect to the adjusting shaft axis and having a closing face extending parallel to the cylindrical wall of the cavity and being rotatable in a cylindrical adjustment plane extending over the feeding and discharge ports. The closing face has a radius which is smaller than the radius of a portion of the cylindrical cavity wall outside the cylindrical adjustment plane, and the closing face has an arc length dimensioned so that the closing face closes the feeding and discharge ports in one rotary position of the cam and, in another rotary position, the closing face extends from one of the rims of the pump intake and ejection port to an inner rim of a respective one of the feeding and discharge ports.
