A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

A sheet dispenser system having a roll of sheet material and a housing to receive the roll. The roll of sheet material comprises a first end portion incorporating a key, and the housing comprises a mounting portion arranged to support the first end portion of the roll and a support portion arranged to support a second end of the roll. The mounting portion comprises a tilting member pivotally coupled to the housing to define an operative position, in which the mounting portion and the support portion are aligned to support the roll in the housing, and a loading position, in which the mounting portion and the support portion are unaligned to inhibit support of the roll in the housing. The mounting portion comprises a block arrangement which is movable between a blocked condition, in which movement of the tilting member from the loading position to the operative position is inhibited, and an unblocked condition, in which movement of the tilting member from the loading position to the operative position is permitted. The mounting portion is arranged such that the roll is movable between an engaged condition, in which the key engages the mounting portion, and a disengaged condition, in which the key is disengaged from the mounting portion, such that, when the roll is moved from the disengaged to the engaged condition, the first end portion of the roll moves the block arrangement into the unblocked condition, thereby permitting movement of the tilting member from the loading position to the operative position.

A sheet dispenser system having a roll of sheet material and a housing to receive the roll. The roll of sheet material comprises a first end portion incorporating a key, and the housing comprises a mounting portion arranged to support the first end portion of the roll. The mounting portion comprises a lock arrangement which is movable between a locked condition and a free condition. The lock arrangement comprises a rotatable element configured for rotation about an axis, and a locking element configured for engagement with the rotatable element to inhibit rotation of the rotatable element, such that, when the locking element and the rotatable element are engaged, the lock arrangement occupies the locked condition, and when the locking element and the rotatable element are disengaged, the lock arrangement occupies the free condition. The mounting portion is arranged such that the roll is movable between an engaged condition, in which the key engages the mounting portion, and a disengaged condition, in which the key is disengaged from the mounting portion, such that, when the roll is moved from the disengaged to the engaged condition, the first end portion of the roll moves the lock arrangement into the free condition, thereby permitting rotation of the rotatable element. The locking element and the rotatable element are configured for engagement by relative movement of the locking element and the rotatable element towards each other in a direction along the axis of rotation of the rotatable element.

The invention describes, and illustrates, a label roll having a roll core and having a label tape, which is wound up onto the roll core. In order that the amount of time and effort required for changing over the label rolls can be reduced without a disproportionately large amount of space having to be provided for the label compartment, provision is made for the roll core to have a plurality of rollers distributed over its circumference, around which the label tape is wound.

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.

A support spindle assembly for rotatably supporting a coreless paper roll for dispensing, the support spindle assembly including a spindle base, a spindle element having a central longitudinal axis (X) and having first and second ends, the spindle element being attached to the spindle base at the first end and rotationally fixed in relation to the spindle base and a rotatable sleeve rotatably disposed about the spindle element, and rotatable in relation to the spindle base and to the spindle element. The support spindle assembly includes a resilient member disposed about the first end of the spindle element, which resilient member is arranged to cooperate with the spindle base and with the rotatable sleeve in order to provide the rotatable sleeve with a rotational resistance.

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.

Refill for a dispenser, with a material web wound to form a roll and at least one substantially axially adjustable bearing journal. The at least one substantially axially adjustable bearing journal is adjustable substantially axially outwards away from the roll starting from a defined inner end position in which it protrudes axially beyond the roll. A bearing unit for such a refill, and a dispenser for housing the refill and dispensing the material web are also provided.

In a movable portion state being a state of a print movable portion including a roll core holder unit configured to support one end portion and another end portion of a roll core, there exist an open state and a closed state. The print movable portion is configured to be movable so that the movable portion state is the open state or the closed state. The roll core holder unit is provided with a support portion. In a support state in which the support portion supports the one end portion and the another end portion, as the movable portion state transitions from the open state to the closed state, a first fitting portion fits into the one end portion and a second fitting portion fits into the another end portion.
