An apparatus for transverse sealing of a packaging tube, filled with products, in order to form bag packages, has a delivery conveyor for delivering the packaging tube, a removal conveyor for carrying the bag packages away and a transverse sealing unit engaging an interstice between these two conveyors. Means is provided for supporting the bag packages at least in part at the transition through this interstice. This means for supporting the bag packages is a supporting base, which reaches beneath the bag packages from two diametrically opposed sides and both supports the bag packages and transports them onward.

Apparatus and method for transverse sealing of a packaging tube

An apparatus for feeding piece goods (P) to a tubular-bag packaging station ( ) has a feed conveyer ( ) for feeding the piece goods (P) and a packaging-material-web conveyer ( ) for conveying the packaging-material web ( ) to the packaging station ( ). A position-detecting unit ( ) serves for detecting the piece goods (P) conveyed on the feed conveyer ( ). Furthermore, at least one gripping unit ( ) is provided for removing the piece goods (P) from the feed conveyer ( ) and for depositing the piece goods (P&prime;) directly or indirectly in a predetermined position on the packaging-material web ( ), it being possible to convey the piece goods (P&prime;) from the packaging-material web ( ) to the packaging station ( ).

Apparatus for, and method of, feeding piece goods to a tubular-bag packaging station

A packaging foil is continuously withdrawn from a supply. The foil is folded around the products to be packaged. Cut-off lengths of closing profile sections are inserted with a feed unit between the two longitudinal edges of the foil. In a sealing station, the two longitudinal edges of the foil are sealed together and the foil is then sealed onto the closing profile sections. In another sealing station, transverse sealing seams are formed between the free ends of successive closing profile sections and the tube is cut approximately in the center of the transverse seams. A high packaging output is achieved as a result of the continuous withdrawal of the foil.

Method and device for producing bags with three sealed edges and welded-in closing seal

An apparatus for sealing a wrapper sleeve includes a first peripheral surface rotating about a first axis and having a generatrix parallel to and at a maximum distance from, the first axis and a radius of curvature smaller throughout the circumferential surface length than the maximum distance. A second peripheral surface rotates about a second axis oriented parallel to the first axis. The first and second peripheral surfaces define a line of contact with the wrapper sleeve therebetween. The first and second surfaces rotate in synchronism and roll on one another effecting sealing of the wrapper sleeve as the wrapper sleeve is advanced. A device displaces the first axis relative to the second axis in a direction transverse to the advancing direction of the wrapper sleeve for effecting displacement of the line of contact in the advancing direction as the first and second surfaces rotate.

Apparatus for sealing a wrapper film sleeve

An apparatus for transversely sealing and severing a thermoplastic wrapper sleeve to obtain individual packages, includes a first welding and severing unit movable back and forth in a first direction and having a first holder; a heated rail and a first clamping mechanism, both supported by the first holder. The first clamping mechanism has first and second clamping components movable toward and away from one another in a second direction oriented transversely to the first direction. A second welding and severing unit is movable back and forth in the first direction and having a second holder; a spring-loaded counter holder mounted on the second holder for cooperating with the rail; and a second clamping mechanism supported by the second holder and having third and fourth clamping components movable toward and away from one another in the second direction. A drive mechanism moves the first and second welding and severing units simultaneously toward one another to clamp the wrapper sleeve therebetween by the first and second clamping mechanisms and to engage the wrapper sleeve by the rail and the counter holder, and for simultaneously moving the first and second clamping components as well as the third and fourth clamping components toward and away from one another.
