A method of wrapping a palletized load includes providing an apparatus with a first wrapping system and a second wrapping system, banding a top edge and bottom edge of stretch film from each of the first wrapping system and the second wrapping system, overlapping the stretch film from the first wrapping system with the stretch film from the second wrapping system to create a composite stretch film, and wrapping the composite stretch film around the palletized load. The edges of the stretch film may be banded by passing the stretch film through a set of adjustment arms. The composite stretch film may have a plurality of sections, where each section is separated from adjacent section by a banded border, a first section, third section, and fifth section each has one layer of stretch film, and a second section and a fourth section each has two layers of stretch film.

Providing a packaging apparatus that can inhibit a reduction in printing quality with respect to a film. A packaging apparatus 1 includes: a film conveyance device 100 that conveys a film F; a moving mechanism that conveys a container C having an opening; a sealing device 40 that seals, with the film conveyed thereto by the film conveyance device, the opening of the container conveyed thereto by the moving mechanism; a printer 140 that is disposed upstream of the sealing device in a conveyance path of the film and prints information in a predetermined position on the film while being conveyed; and a controller that controls the operation of the film conveyance device. The film conveyance device has the accumulation mechanism 120. The accumulation mechanism is disposed between the printer and the sealing device in the conveyance path of the film and temporarily accumulates the film printed with the information. The controller controls the film conveyance device so that the accumulation mechanism accumulates at least the film that is utilized for one packaging operation in the sealing device.

In a method for packaging products, the products are packaged with a packaging material on a packaging line. The packaging material is first of all drawn off a first packaging-material reel and fed to the packaging line. When the first packaging-material reel has been at least partially used up, an initial portion of a second packaging-material reel is made to overlap with a packaging-material portion already drawn off the first packaging-material reel and is joined to the latter packaging-material portion. After the two packaging-material portions have been joined together, the packaging material is drawn off from the second packaging-material reel and fed to the packaging line. The two above-mentioned packaging-material portions are joined together by a stamping operator of a stamping device. There is also described a packaging installation for carrying out the method.

A stretch film dispenser includes a frame. The frame has a top seat and a bottom seat. The top seat and the bottom seat are jointly equipped with a film mounting unit and a film dispensing unit. The film dispensing unit includes a first roller and a second roller. The first roller and the second roller have a strip hole. The strip hole is located between the first roller and the second roller. Through the strip hole of the first roller and the second roller, the front end of a film can pass through the strip hole between the first roller and the second roller easily and quickly, and the film is pulled out along the direction of the first roller, thereby achieving the effect of easy and convenient installation of the film.

The present invention relates to a film wrapping machine for a product packing device using a stretch film, including a frame having vertical bars extending upward and spaced apart from each other, a film clamping unit including a pair of suction pads which are moved in a direction of being spaced apart from each other in a state of adsorbing the stretch film so that a front end portion of the stretch film supplied from a film supply device is opened, and a plurality of clamps configured to grip the front end portion of the stretch film opened by the suction pads, receive the stretch film whose upper end is cut and bonded by the film supply device in a wrinkled state, and process the stretch film to be covered on a product in a process of lowering the vertical bars, and a controller which controls operation of the film clamping unit and the film supply device.

The present invention refers to an apparatus and a method for wrapping a film around an object. The apparatus includes a device capable of being electrostatically charged and capable of transmitting the electrostatic charge to the portion of film that comes out of the carriage. In this way, the fixing of the leading end flap of the film around the object to be wrapped is thus facilitated. In fact, the leading end flap of the film, as soon as it is dispensed, remains stretched out of the carriage and, as soon as it meets the object to be wrapped, it immediately fastens to it due to the attraction force. The rotation is then activated to wrap the film around the object. The apparatus is simple to make, cheap, and highly efficient.

A bag-making and packaging apparatus includes a bag-making and packaging unit, a film feeding unit, a splicing device, and a control unit. The control unit allows a bag-making operation to continue by utilizing an auto-feeding function that feeds to the bag-making and packaging unit a film F spliced by the splicing device to take the place of a film F currently being fed to the bag-making and packaging unit. When the control unit judges that at least one of the film feeding unit and the splicing device is malfunctioning in a case where the control unit is utilizing the auto-feeding function, the control unit stops the auto-feeding function and executes a non-auto-feeding mode. The non-auto-feeding mode allows the bag-making operation to be continued by the bag-making and packaging unit and a film roll holding unit that is operable among plural film roll holding units.
