An apparatus for exchanging paper rolls includes a paper supply mechanism having an inclined arm and a clamp assembly for receiving and holding a first paper roll; a second-roll hanger assembly arranged above the paper supply mechanism for receiving and holding a second paper roll; a slide rail arranged between the paper supply mechanism and the second-roll hanger assembly; an elevating assembly movably mounted to the slide rail; and a driving assembly for driving the elevating assembly to move along the slide rail. The elevating assembly picks up the second paper roll from the second-roll hanger assembly. To exchange the first paper roll with the second paper roll, the clamp assembly pushes the first paper roll away from the paper supply mechanism, and the elevating assembly lowers down along the slide rail to place the second paper roll in the paper supply mechanism.

A wrapping paper storage and dispensing device comprises a storage housing housing a rotating drum having a plurality of tubular canisters. A fixed longitudinal cutting base and a corresponding blade track supported by two pivoting arms are positioned on one side of the housing. A blade carriage slidingly engages the longitudinal blade track with a sliding ratcheting lock mechanism. The ratcheting lock comprises a retractable blade in the blade carriage which locks in place when the blade is extended through a slit in the blade track. The canisters are formed by cylindrical tubes having a rectangular openings extending along their longitudinal lengths, stationary first end caps, sliding second end caps, and sliding tensioners engaged to the canister between the first end cap and the second end cap.

A roll sheet with a continuous sheet wound in a roll form is rotated in a forward direction to supply the sheet to a printing unit. A sensor whose output is changed in accordance with a distance between the sensor and the sheet is used. A rotation direction of the roll sheet is switched from an opposite direction to the forward direction on the basis of the output of the sensor during rotation of the roll sheet in the opposite direction.

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.

A printing apparatus includes a plurality of set units to set rolled print media, a conveyance unit to convey the print media, a printing unit, a detection unit, and display units. The printing unit prints an image on the print media conveyed by the conveyance unit. The detection unit detects whether any one of the print media is fed to a predetermined printable position at which printing is performable by the printing unit. Each display unit is provided on a different one of the plurality of set units and configured to indicate whether a print medium set in a corresponding set unit is being fed. When the printing unit performs printing on the print medium, each display unit indicates whether the print medium set in the corresponding set unit is being fed in accordance with a result of detection performed by the detection unit.

A material dispensing system including a first frame and a first application head. The first application head supported by the first frame including a first bias ply assembly comprising a bias ply roll supported on a bias ply dispenser unit, the first bias ply assembly configured to pass bias ply material along a bias path; and a first non-bias ply assembly comprising a non-bias ply roll supported by a non-bias ply dispenser unit, the non-bias ply assembly configured to pass non-bias ply material along a non-bias path; wherein the bias path and the non-bias path are substantially parallel. Another aspect provides a material dispensing system including a first frame and a first application head supported thereby; and a second frame and a second application head supported thereby; wherein the first frame and the second frame move in an X direction during operation. Another aspect includes preparing a composite article.

In one aspect, the present disclosure is directed to a dispenser assembly for dispensing supplies of sheet material. The dispensing assembly can include a carrier supporting the supplies of sheet material and being moveable along a track between various dispensing positions. The dispenser assembly also can include a carrier pivoting assembly with a lever that engages one of the supplies of sheet material and rotates during dispensing thereof, as well as one or more biased pins connected to the lever and configured to engage locking features provided along the track to support the carrier in one of the dispensing positions. The biased pins further can be configured to retract with rotation of the lever such that they disengage the locking features so the carrier to moves along the track to different dispensing position. Other aspects also are described.

An unpowered, manually operable apparatus for dispensing cushioning wrap material drawn concurrently from a roll of separator material and a self-contained cartridge that includes a roll of expandable sheet material. The rolls are supported on a stand for rotation about respective parallel, spaced-apart axes. In addition to the roll, the cartridge includes a tensioning assembly and support panels that abut respective ends of the roll. The tensioning assembly and the support panels cooperate with the stand to control rotational resistance of the roll. The rotational resistance causes the expandable sheet material to expand in length and thickness as it is manually pulled from the stand with the separator material, and support surfaces on the stand hold the cartridge and the separator roll in position. When the cartridge containing the expandable sheet material is depleted, the cartridge is readily removed and replaced.

An improved tape delivery assembly for delivering a turn-up tape across a moving web of paper being wound onto a spool, the assembly being part of a paper web turn-up system, the tape being used to sever and transfer the leading edge of the cut paper web onto an empty spool. A secondary tape dispensing module may deliver a secondary turn-up tape while a primary tape delivery module is temporarily removed from the paper web turn-up system.

The invention relates to a method for a multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region and for which a normal length is predefined which is dependent on the respective application, in which material webs are removed from at least two material stores which are each associated with one or more tracks; and in which the material consumption of at least one material store is impacted during operation, in particular in dependence on residual quantities in the material stores, in that the length of the interleaved sheets is varied in the respective track or tracks with respect to the normal length at least for this material store.
