A feeding unit for feeding a plastic film in packaging machines for wrapping paper rolls, including: a unit for unwinding the film from a reel; a cutting device adapted to cut the film transversely; a transfer device including, on the right and on the left side of the feeding unit, drive belts configured for engaging the upper and lower faces of the film; and a positioning device including, on the right and on the left side of the unit, a predetermined number of drive belts configured for engaging the upper and lower faces of the film. On each side of the feeding unit, the transfer device comprises two pairs of belts. On each side of the feeding unit, the positioning device comprises a third pair of belts. The three pairs of belts are actuated by independent actuators.

A method of providing a rollable display device includes providing a display panel for displaying an image, a printed circuit board connected to an edge of the display panel, and a roller which the display panel is rolled onto or unrolled from. The roller has a cylindrical shape having an inner space, and the printed circuit board is disposed in the inner space.

A wrapping mechanism is described that comprises at least two material support cylinders, a mechanism support cylinder, and a first and a second support plate, which are all rotatable about a support axis. The wrapping mechanism can comprise a pair of frame plates, a drive mechanism, a brake system, a lock mechanism, at least one feed roller and a feed plate. The wrapping mechanism can be integrated into an agricultural harvester such as a baler or combine.

A dispenser for dispensing sheet product is provided including a housing that defines an interior configured to accommodate a source of sheet product and an outlet through which the sheet product is dispensed. The dispenser also includes a first roller that is rotatable and disposed in the housing. A portion of the sheet product is designed to be in contact with the first roller prior to being dispensed through the outlet. The dispenser also includes a knife drum that is rotatable and configured to cooperate with the first roller to dispense the sheet product. The knife drum includes a knife configured to cut the sheet product into individual sheets. The dispenser also includes a spring assembly that may be configured to bias the knife drum toward a predetermined position during rotation of the knife drum.

A house wrapping device to connect to a wall of a building, the house wrapping device including a main body having an elongate shape, a wrap receiving rod perpendicularly disposed away from a first end of the main body with respect to a direction to receive a house wrap roll thereon and dispense a house wrap from the house wrap roll, and a wedge perpendicularly disposed away from a second end of the main body opposite to the first end with respect to the direction to removably connect the main body to the wall and prevent the main body from falling off the wall.

An upper-side conveyance guide of a temporary holding section is provided with an upper-side movable guide that capable of moving in coordination with the drum diameter of a drum so as to be interposed between the upper-side conveyance guide and the drum at all times. The upper-side movable guide guides a banknote that is being conveyed gripped only at the center by a banknote conveying portion of a main tape, between the upper-side conveyance guide and the drum. Folding of the banknote is accordingly suppressed by the upper-side movable guide, enabling the banknote to be guided to a gap between the upper-side conveyance guide and a lower-side conveyance guide without catching on a rear face of the upper-side conveyance guide or the like. Accordingly, the banknote can be prevented from contacting portions that should not be contacted and causing conveyance issues as a result.

A rollable display device includes a display panel for displaying an image, a printed circuit board connected to an edge of the display panel, and a roller which the display panel is rolled onto or unrolled from. The roller has a cylindrical shape having an inner space, and the printed circuit board is disposed in the inner space.
