A magazine has a generally rectangular, prismatic shaped body with a lid. The body has a front with an opening, an opposite back, a bin upon the back, a left side and an opposite right side spanning from the front to the back, a toothed rack on each side, a spindle assembly between the two racks, and a base beneath the front, the back, and the two sides. The lid rests upon the front, the back, the left side, and the right side in a spacing above the base. Each spindle of the assembly receives a roll of wrapping paper, oriented parallel to the front. Each spindle has an end cap and an opposite movable cap engaging a dock upon a cover. The spindles rotate upon gears with the spindle assembly upon the racks. Grips upon each spindle allow a user to unroll paper as desired.

A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has holding mechanisms each having a shaft that holds a film roll, a holding mechanism support frame supporting the holding mechanisms, a moving mechanism that rotates the holding mechanism support frame to move each holding mechanism between a film roll setting position and a film supply position, a splicing mechanism splicing a trailing end portion of the film of the roll of one of the holding mechanisms and a leading end portion of the film of the roll of another one of the holding mechanisms, and a film drawing mechanism that rotates the shafts of the holding mechanisms to draw the film independently from the film rolls attached to the shafts of the holding mechanisms and changes the drawing speed of the film during bag-making and packaging.

A reel assembly includes a plurality of reels coupled to a reel support device. The reels are configured to rotate relative to the reel support device to dispense materials. The reel support device includes a first plate coupled to a second plate with fasteners that are coupled to first holes in the first plate and include a fastening portion received in second holes in the second plate. The fasteners are removably coupled to the second holes, such that an operator can rotate the first plate relative to the second plate by applying a lateral force to the first plate to remove the fastening portion from the second holes. The first plate rotates until the fastening portion is secured in a successive one of the second holes. During normal operation, an elastic element in the fasteners holds the first plate in position until the force is provided by the operator.

A reel holder includes: a plate-shaped rotating plate; multiple reel support portions evenly arranged in a circumferential direction about the center of the rotating plate, and supporting the tape reels such that each of the tape reels is rotatable about the center thereof; and a rotating plate support portion supporting the rotating plate such that the rotating plate is rotatable about the center of the rotating plate.

A feeding device for an electrostatic bag, adapted for supplying electrostatic bags to a package mechanism so as to warp an SSD with an electrostatic bag, includes two carrying mechanisms arranged up and down, which respectively support at least one reel that is wound with multiple electrostatic bags. A feeding position is provided between the two carrying mechanisms and face the package mechanism. The two carrying mechanisms are movable up and down to switch positions with one another. The feeding device for an electrostatic bag can supply electrostatic bags to a package mechanism, reload the electrostatic bag without stopping the machine, and ensure the continuous operation of the package mechanism.

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.
