A machine for packaging articles into bags made of heat-sealable flexible material starting from a reel of a continuous web having two superimposed flat layers mutually permanently joined along one side and providedalong the other sidewith an openable closure. The machine includes a device for supplying the web having a pair of superimposed parallel guide rollers arranged transversely on opposite sides with respect to the web and whose angular position with respect to the advancement direction of the web is adjustable. The two guide rollers have a superficial shape suitable to avoid both the formation of irregularities of the websuch as folds and creasesas well as the damaging of the openable closure.

The present invention concerns a device and method for reefing a portion of tubular film, the reefing device having at least one reefing finger and at least one drive unit. The drive unit has advancing means, which, for reefing the portion of tubular film, is brought into operative connection with the reefing finger at least at the height of a point of engagement, while enclosing the portion of tubular film, and moves the portion of tubular film in relation to the reefing finger. The device according to the invention and the method according to the invention are distinguished in particular in that the position of the at least one point of engagement can be changed along the reefing finger as reefing progresses or the position of the point of engagement on the reefing finger is changed.

The present invention relates to a device for wrapping a piece item stack, which is formed of a plurality of piece item parts that are disposed on top of one another, with a tubular film, wherein the device has a tubular film stock, a conveyor device for pulling a predetermined length of tubular film out of the tubular film stock, a cutting device for cutting the pulled-off tubular film for the formation of a tubular hood and a fitting device, which is arranged downstream of the cutting device in the conveying direction of the tubular film, for pulling the tubular hood over the piece item stack, as well as a method for changing the tubular film stock in such a device. For enhanced safety and guarantee of a disturbance-free operation, a discharge device, which can discharge a length piece (L) of the tubular film, is proposed with the present invention as a part of the device for wrapping the piece item stack. In the method for changing the tubular film stock according to the invention, a lagging end of a consumed tubular film stock is connected to the leading end of a new tubular film stock, wherein the leading end and the lagging end are conveyed in the direction onto the cutting device in order to laterally discharge a length section (L) that bears the leading and the lagging end on top of an intake area for the piece item stack.

An apparatus for packaging an object with a tubular film, includes: a main frame, a stretch frame for stretching the tubular film and for applying the tubular film to the object, and a top frame having a feeding device for delivering a tubular film from a film magazine to the stretch frame and having a cutting device to cut the tubular film to a predetermined length. The top frame is moveable at the main frame between a working position and a maintenance position. In the maintenance position the top frame is located outside the work space.

This invention relates to a shrink wrap machine, which includes a central column and a shrink film synchronous transmission equipment. Said central column is provided with a first column and a second column which are configured to mutual suspended separation for removing the connection between the first column and the second column so that the shrink wrap machine can be expand to fit onto the desired diameter range of bottles or cans and increase the application of the shrink-film. When the shrink-film is opened by the first column of the center column, the shrink-film will be continuously transport by the label feeding rollers and the label pulling rollers of said shrink film synchronous transmission equipment. After the shrink-film is cut by the cutter equipment, a piece of the shrink-film will be pulled down by the label pulling rollers and the second guide pulleys and the shrink-film will be wrapped on the surface of the bottles or cans. Then the conveying equipment will convey the bottles and cans toward to the next equipment and making the shrink film and the bottles or cans be shrunk packaging completely.

A packaging apparatus for compressed pressed bales (25) is designed to apply a bale packaging (32) to the pressed bale (25) and has a transporting device (5), which is designed to remove a compressed pressed bale (25) from a press (3, 3). The transporting device (5) has a movable bale receptacle (6) for picking up the compressed pressed bale (25) on two opposite sides, wherein the bale receptacle has several elongated support elements (20) arranged at a distance from one another on each of the areas intended to retain the pressed bale.

Method of coiling a flexible elongate element (64) inside a container (80A) made from a flexible sheet material wherein at least part of the sheet material is tensioned by establishing a pressure differential between an inner surface (100) and an outer surface (92) of the sheet material and the flexible elongate element (64) is directed onto the tensioned sheet material to form a hole (98), the flexible elongate element being then fed through the hole to form a coil inside the container.
