There is described a method for feeding a supply station (6) of a packaging unit (1) with a new reel (3a) of sheet packaging material, comprising the steps of releasably connecting a sheet packaging material holder (11) to a support structure (5); coupling an end portion (52) of new reel (3a) with holder (11) connected, in turn, to support structure (5); carrying out on end portion (52) at least an operation, which is preliminary for joining of end portion (52) to a first edge (53) of a terminated reel (3a′, 3b) previously connected to packaging unit (1); moving new reel (3) together with holder (11) from support structure (5) towards supply station (6); and releasably connecting a fixed part (12) of supply station (6) to holder (11) together with new reel (3a).

A web material dispenser for housing two or more rolls is provided. The web material dispenser includes a housing having a fixed housing portion provided with a first roll support assembly coupled thereto for supporting a first roll of web material. The housing further has a movable housing portion, movable between a closed position and an open position, provided with a second roll support assembly coupled thereto for supporting a second roll of web material. The fixed and movable housing portions defining a housing chamber therebetween when the movable portion is in the closed position, for at least partially enclosing the two or more rolls of web material within the housing chamber. The movable portion is moved to the open position for providing access to the two or more rolls and allowing replacement of at least one of the first and second rolls.

An improved paper band delivery assembly for reliable high speed delivery of a turn-up paper band across a moving web of paper being wound onto a spool. The turn-up paper band is made ready for a turn up procedure by coiling a predetermined length of paper band suitable for a particular machine and retaining the coiled paper band in a reservoir pending deployment across a spool for a turn up procedure. The paper band may be coiled via manual operation or via automated operation. Coiling apparatus may be modularly replaced on a paper making machine. The coiled paper band may be supported within the reservoir on rollers, pins, or other items conducive to fast and reliable uncoiling.

An apparatus for dispensing an adhesive with paper covers to be used in a paper web turn-up operation. The resulting adhesive and paper cover construct is used in effecting the attachment of a paper web to an approaching spool. In some examples, the paper cover of the deposited adhesive may be affixed on two sides surrounding the deposited adhesive, in other examples a single attachment may be used. In some examples, the paper cover may be perforated to facilitate rupture of the paper and flow of adhesive. In some examples, perforations may enable the movement of adhesive through the paper.

An image forming apparatus includes a housing, a feeding tray capable of being inserted into and pulled out from the housing, a feed roller, and one or more detection units. The feeding tray includes a first accommodation part in which a roll body having a configuration where a sheet-shaped medium is rolled in a roll shape is accommodated and a second accommodation part in which a plurality of sheet-shaped media are accommodated in a state of being stacked. The feed roller feeds a sheet-shaped medium from the feeding tray toward a conveying path. The image forming unit forms an image on a sheet-shaped medium provided in the conveying path. The one or more detection units detect whether a sheet-shaped medium is arranged in a predetermined position in the feeding tray.

An arm for an unwinder for unwinding rolls is disclosed. The arm includes an axial engaging member for engaging the rolls. The axial engaging member has a shaft supported by at least two support bearings mounted on the arm, so as to rotate around a rotation axis. A brake is also provided, adapted to act on the shaft. The brake is at least partially arranged between the two support bearings.

A web loader includes a web holder configured to hold a web, a traction member configured to hold the web holder and travel along a loading path of the web, a drive rotation body configured to drive the traction member to travel, and a limiter configured to limit a drive force applied to the drive rotation body.

A sheet-feeding system includes a holding part which holds an end portion of a sheet, a nozzle part for discharging an adhesive agent for joining sheets to each other, and a nozzle moving unit which supports the nozzle part such that the nozzle part is made movable within a region including both temporarily holding parts, in which when a sheet joining condition is established where a remaining amount of the sheet on one original sheet roll becomes equal to or below a predetermined remaining amount, an end portion of the sheet on the other original sheet roll is conveyed to the temporarily holding part by the holding part and, thereafter, the nozzle part is moved to the temporarily holding part, and the adhesive agent is discharged to the end portion of the sheet from the nozzle part.
