Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention is concerned with aseptically operating packing machines and with a process for the pre-sterilization thereof. For jointly spraying steam and sterilizing agent at a single point into a sterile air supply channel which terminates in the sterile chamber of the packing machine, a mixing nozzle is arranged in the air supply channel directly downstream behind a sterile air filter. For pre-sterilizing purposes the treatment tools possibly still in hot condition and contained in the sterile chamber, prior to commencement of the pre-sterilizing process, are brought to a temperature below 120° C. The mixture of water vapor and sterilizing agent is effectuated by means of the mixing nozzle to which both components are supplied. The steam supply to the nozzle is effectuated by a pressure relief valve followed by a regulation of the steam volume, while the supply of sterilizing agent to the nozzle is effectuated from a stock of sterilizing agent held at a constant pressure.

Abstract: The invention is concerned with a process of sterilizing at least the load-sided surface of sheets of packing material by using saturated steam, and with an arrangement for carrying out the process. According to the process, the saturated steam prior to application thereof to the sheet section contained in the sterilization passage chamber is converted by a controlled energy supply into superheated steam. The said superheated steam is jetted with substantially uniform intensity across the entire length of at least one transverse line of the sheet of packing material onto the sheet to form a uniformly thin condensate film on the sheet of packing material. The so sterilized sheet of packing material, while maintaining the sterile conditions, is then supplied to a packing machine connected thereto which also operates under sterile conditions.

Abstract: 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.
