Abstract: Various device embodiments include first and second plate assemblies. Each plate assembly includes a base, a seal plate, one or more air bladders and a servo motor to provide a linear motion of the seal plate with respect to the base. The device further includes at least one plate assembly motor operably linked to the bases of the plate assemblies to provide a linear motion of the first and second plate assemblies toward each other to perform a sealing operation and away from each other. The device further includes a controller connected to the at least one plate assembly motor and to the first and second servo motors to coordinate the motion of the first and second seal plates to perform a seal operation on a web while traveling with the web.

Abstract: 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.

Abstract: The invention relates to a method and device for heat-sealing windows into folding carton blanks for producing liquid-proof folding cartons having film windows. Pieces of film that are cut to measure are placed on the window openings of the folding carton blanks and the edges of the pieces of film are heat-sealed with the folding carton blanks so as to be liquid-proof using heated pressure segments or heat-sealing dies. The folding carton blanks, together with the pieces of film, are fed to a tail pulley for a transport belt by means of the transport belt and are inserted in the gap between the tail pulley and the transport belt resting thereon. In this gap, the blanks and pieces of film are continuously heat-sealed together by means of at least two heated pressure segments that are disposed on the outer periphery of the tail pulley and push radially from inwards against the transport belt in the area of deflection of the transport belt and thus onto the edges of the pieces of film.

Abstract: The wrapping of groups of products positioned according to a determined number of mutually superposed layers is achieved by feeding in succession groups of products firstly into a tubular case made to heat-sealable material and, then, to a first wrapping device when the number of layers is equal to one and to a second wrapping device when the number of layers is at least equal to two; the two wrapping devices being able to wrap each group inside a related wrapping sheet, which is folded substantially in contact with the related group, and which is stabilized by means of sealing operations.

Abstract: A form and seal unit (1) for producing aseptic sealed packages from a tube (2) of packaging material filled with a pourable food product; the unit having a fixed structure (3), and two forming assemblies (5, 5′) interacting alternately and cyclically with the tube (2) of packaging material, and in turn having respective pairs of jaws (7) movable between an open position and a closed position in which the jaws grip the tube (2) of packing material between respective sealing members (13, 14), and respective forming flaps (21) having respective half-shell forming portions (22) which surround the tube (2) of packaging material to determine the shape and volume of the packages; the closing movement of the forming flaps (21) about the tube (2) of packaging material is controlled by cams (30) carried by the forming flaps (21) and interacting with rollers (64) fixed to the structure (3) of the unit (1).
