A frame for cradling a rolled surface covering during installation onto a ground surface, including first and second spaced-apart end panels, a surface covering support base extending between the first and second spaced-apart panels and adapted for holding the rolled surface covering during installation. At least one lower roller extends along the support base between the first and second spaced-apart end panels at a level above the support base, and at least one upper roller extends along the support base between the first and second spaced-apart end panels at a level above the support base and is vertically spaced-apart from the at least one lower roller. The space defines a gap extending along a length of the at least one lower roller and the at least one upper roller through which a free end of the rolled surface covering is extended during installation onto the ground surface.

A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.

A spool-less system for deployment, recovery and manipulation of a traversable road covering track. The system includes an arcuate guide member detachably coupled to a retaining member; the guide member and retaining member defining a volume for receiving a roll of traversable road covering; the guide member arranged to contact the roll along a first arcuate range and the retaining member configured to contact the roll along a second arcuate range; and wherein the guide member and retaining member are detachably coupleable having, a first position in which, the guide member and retaining member are separated at a first diameter whereby the roll of traversable road covering may be deployed or recovered when the host machine is in motion, and a second position in which, the guide member and retaining member are separated at a second diameter in which the roll of traversable road covering is retained.

A printer includes a medium supplier including a shaft support, to which a supply shaft of a roll medium is detachably attached, a medium temporary placement support located below the shaft support of the medium supplier and that receives and supports the roll medium prior to being attached to the medium supplier, and a conveyor that conveys a medium in a conveyance direction that is perpendicular or substantially perpendicular to an axial direction of the supply shaft, the medium being unwound from the supply shaft. The medium temporary placement support includes a support bar that extends in the axial direction, and a placement seat supported by the support bar. The placement seat includes a placement surface on which the roll medium is placed and that extends in the conveyance direction, and a curved portion that includes a convex curve in an upstream end portion of the placement surface in the conveyance direction.

An apparatus and method for supporting sheet material, comprising a frame including a first arm and a second arm, the second arm in communication with the first arm to support a roll of the sheet material there-between, and a drive roller for transporting the sheet material from the roll. The first arm and the second arm automatically resize the frame corresponding to the dimensions of the roll of the sheet material to provide constant tension in the roll of sheet material by controlling a position of the roll of the sheet material.

A frame for cradling a rolled surface covering during installation onto a ground surface, including first and second spaced-apart end panels, a surface covering support base extending between the first and second spaced-apart panels and adapted for holding the rolled surface covering during installation. At least one lower roller extends along the support base between the first and second spaced-apart end panels at a level above the support base, and at least one upper roller extends along the support base between the first and second spaced-apart end panels at a level above the support base and is vertically spaced-apart from the at least one lower roller. The space defines a gap extending along a length of the at least one lower roller and the at least one upper roller through which a free end of the rolled surface covering is extended during installation onto the ground surface.

A medium unit, having a tray, a casing, and a pullback assembly, is provided. The tray stores a roll of medium, in which a continuous medium is rolled. The casing supports the tray detachably attached thereto. The pullback assembly pushes the continuous medium from a lower side to pull a loose end of the continuous medium unrolled from the roll of medium in conjunction with a detaching action to move the tray to detach from the casing in an orthogonal direction intersecting orthogonally with a rotation axis of the roll of medium.

A roll medium is accommodated in a medium cassette. The roll medium has a configuration where a continuous medium is rolled in a roll shape. The medium cassette has a supporter including two sets of support roller pairs which rotatably support the roll medium. The two sets of the support roller pairs are in contact with an outer peripheral surface of a lower part of the roll medium at each of end positions, where a lower end of the roll medium is sandwiched between the support roller pair, of the roll medium in a direction of a rotation axis of the roll medium, and are not in contact with the outer peripheral surface of the lower part of the roll medium at a central portion of the roll medium in the direction of the rotation axis.

A roll supporting device includes: a pair of supporting rollers which support an outer circumferential surface of a rolled medium, and which are provided so as to rotate together with the rolled medium; a side wall which has a reference surface coming into contact with one end surface of the rolled medium in an axial direction along a central axis of the rolled medium; and a pair of restricting members which press another end surface of the rolled medium toward the reference surface. The pair of supporting rollers are disposed on both sides of the central axis of the rolled medium when viewed in the axial direction of the rolled medium. The pair of restricting members are disposed outside a space between the pair of supporting rollers in a circumferential direction of the rolled medium, and are respectively adjacent to the supporting rollers, and are provided so as to be movable independently from each other.
