The apparatus (10) for processing a continuous band of wrapping material (40) comprises a roller pair (20, 30) defining a roller gap (12) there between, wherein the rollers (20, 30) have matching convex and concave shapes, respectively. The invention is also directed to a corresponding method for treatment of wrapping material (40).

In a film supplying device in a package machine, a film drawn out from a film roll is fed downstream between a drive roll and a driven roll. The drive roll is rotatably supported by a first support fixed to a main frame. A second support for rotatably supporting the driven roll is supported on the main frame so as to be rotatable. The second support is movable between a sandwiched position where the driven roll approaches the drive roll to be aligned therewith to hold the film therebetween, and a retract position in which the driven roll is spaced apart from the drive roll.

An image forming apparatus includes an image forming unit to form an image on a sheet, a sheet ejection section to which a relay unit and a sheet processing apparatus are removably coupled, a driving-side ejection roller disposed in the sheet ejection section, to eject the sheet outside the apparatus, a plurality of driven-side ejection rollers that are replaceable, one of which is disposed facing the driving-side ejection roller, and a roller holder removably secured to the sheet ejection section to hold the one of the plurality of driven-side ejection rollers. Each driven-side ejection roller has a shaft and a plurality of roller bodies attached to the shaft and lined in an axial direction of the shaft. The driven-side ejection roller is replaced with another driven-side ejection roller in accordance with whether or not the relay unit and the sheet processing apparatus are coupled to the sheet ejection section.

A stacking apparatus includes a conveyance unit, a stacking unit, and a separation member supply unit. The conveyance unit conveys sheets for circuit board. The stacking unit stacks the sheets. The separation member supply unit supplies a separation member to separate the stacked sheets at any position. The separation member supply unit places the separation member on the sheet in being conveyed.

In a film supplying device in a package machine, a film 12 drawn out from a film roll is fed downstream between a drive roll 32 and a driven roll 34. The drive roll 32 is rotatably supported by a first support 38 fixed to a main frame 26. A second support 56 for rotatably supporting the driven roll 34 is supported on the main frame 26 so as to be rotatable. The second support 56 is movable between a sandwiched position where the driven roll 34 approaches the drive roll 32 to be aligned therewith to hold the film 12 therebetween, and a retract position in which the driven roll 34 is spaced apart from the drive roll 32.

A collapsed adhesive tape tube dispenser for dispensing adhesive tape rolls. The dispenser having a baseplate having a first end, a second end, and a baseplate center line extending longitudinally in the machine direction. A tape roll unwind supported by the baseplate near the first end. A mandrel extending in the machine direction having a mandrel first end and a mandrel second end with the mandrel second end being cantilevered and unsupported. An exterior forming die positioned between the first end and the second end, and the exterior forming die having a shaping portion with a threading slot. A compression roller located near the second end for flattening the adhesive tape tube structure.
