The invention relates to a device for, and method of, applying, drying and activating hot glue on the packaging machine itself. In the case of the basic option, the device works as follows: two assemblies (1) for applying and drying glue are positioned on the plates (3) of machine (M). Assemblies (1) are made up of consoles (11) mounted in a way that enables them to slide and move, their front end on the lever (32) and their rear end on the shaft (31) attached between two plates (3). The lever (32) is attached, by way of levers (33), between the plates (3). One device (12) for applying hot glue is attached to the consoles (11), just above the lever (32), while a number of fans (13) are fastened along the console (11), above the device (12), as well as on the opposite side. The heater (4) is horizontally attached to the carrier (42) and positioned in the opening (43) on the plate (41). The strip heater (7) is made up of an endless strip (71) and vertical heaters (72). In the case of the basic option, the method of applying, drying and activating hot glue on the packaging machine itself consists of the following: paper (5) from the roll (51) is introduced under the consoles (11). The devices (12) apply hot glue to the top side of the paper in a continuous strip (61) and a discontinuous strip (62). Strips of glue (61, 62) are dried by fans (13) and further transported through the machine (M), together with the paper (5). Once the product is packaged, packages reach a horizontal heater (4) which activates the glue (61, 62) on the bottom side of the package, after which product packages pass between vertical heaters (72) which activate the glue on the sides of packages.

A heat sealing apparatus includes: a first sealing unit and a second sealing unit which are provided to be capable of being opened and closed and perform a heat sealing process of a bag while nipping the bag in a state where the first sealing unit and the second sealing unit are arranged in a closed position with the bag positioned between the first sealing unit and the second sealing unit; and a heat shield member including a heat reflector which is provided to cover at least a part of the first sealing unit and the second sealing unit arranged in the closed position, at a position away from the first sealing unit and the second sealing unit.

The disclosure refers to a packaging device for manufacturing a packaging for a foodstuff. In particular, the packaging may include a trough-shaped lower packaging part and a top film which can be sealed together along their edges by means of a sealing tool of the packaging device. In order to improve a packaging device completely without evacuation or by evacuation in a simple and inexpensive manner with only a slight negative pressure in such a way that sufficient vapor purging is possible and at the same time cooling of the foodstuff before sealing or excessive degassing of the foodstuff does not take place, vapor can be introduced under pressure between the lower packaging part and the top film at at least one vapor entry point before sealing and can be released into the surrounding atmosphere at an outlet point from the packaging.

Machine (1) for filling bags (100) with a granular product comprising a filling station (2). The machine comprises a supporting device (8) for supporting bags (100) below the filling station (2). The supporting device (8) comprises an assembled supporting surface (10) pivoting on a pivot shaft (12), and actuating means (18). The actuating means (18) are a motor the angular position of which is controlled by control means (32). The supporting surface (10) has a first end (14), arranged upstream of said filling station (2) in the forward movement direction of the bags, and a second end (16), arranged downstream of said filling station (2) in the forward movement direction of the bags. The supporting surface (10) can pivot in an alternating manner around said pivot shaft (12) for moving the base of the bag (100) which is located in the filling station (2) in operation during filling. The invention also relates to a method for filling said bag.

Provided are a method and an apparatus for extruding into a tube and filling the tube at a high speed and simultaneously sealing the tube. Specifically provided is a method for producing a polymer tube, containing a liquid therein and being sealed at constant intervals, the method including an extrusion step of continuously melt-extruding a polymer material through a die into at least one tube, while feeding a liquid into the tube to obtain at least one liquid-containing tube; and sealing step of discontinuously pressing the at least one liquid-containing tube between a pair of pressurizing members at constant intervals to cause pressure-bonding before the tube solidifies, while continuously taking up the extruded tube.

The present invention relates to a machine for filling bags with a granular product comprising a filling station, a welding station, and a cooling station. The machine comprises a supporting device for supporting the bags below the stations. The device comprises a supporting surface assembled in a pivoting manner on a pivot shaft, and actuating means. The supporting surface has a first supporting segment for supporting the bags of the filling and welding stations on one side of the pivot shaft and a second segment for supporting the bag of the cooling station on the opposite side of said pivot shaft. The supporting surface can pivot in an alternating manner around said pivot shaft for moving the base of the bag which, in operation, is located in the filling station during filling. The invention also relates to a filling method.
