There is provided a print device including: a casing having an inner space; a support which extends along a first direction and which is configured to rotatably support a roll body; a conveyer configured to convey a sheet pulled out of the roll body in a conveyance orientation along a second direction orthogonal to the first direction; a print unit configured to perform a print by causing a print matter to adhere to the sheet conveyed in the conveyance orientation; and a cover. An opening is provided on the casing such that the inner space is exposed to an outside of the casing via the opening. The cover is configured to slide relative to the casing along the second direction between an open position in which the opening is uncovered and a close position in which the opening is covered by the cover.

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 reel assembly includes a plurality of reels coupled to a reel support device. The reels are configured to rotate relative to the reel support device to dispense materials. The reel support device includes a first plate coupled to a second plate with fasteners that are coupled to first holes in the first plate and include a fastening portion received in second holes in the second plate. The fasteners are removably coupled to the second holes, such that an operator can rotate the first plate relative to the second plate by applying a lateral force to the first plate to remove the fastening portion from the second holes. The first plate rotates until the fastening portion is secured in a successive one of the second holes. During normal operation, an elastic element in the fasteners holds the first plate in position until the force is provided by the operator.

A roll type raw material supply device includes a raw material mounting unit for introducing a roll type raw material to which a tape for fixing to the end portion of a raw material is attached; a tape removal unit for clamping a non-bonding portion of the tape and separating the tape from the raw material; and a raw material conveying unit for attaching and moving the raw material. The roll type raw material supply device is capable of automatically and effectively removing the tape attached to a roll type raw material and causing the end portion of the raw material to be moved to a desired location without damage such as warping.

In a system for facilitating the wrapping and taping of articles with wrapping materials, two or more apparatuses adapted to be secured in adjacent spaced relation on a planar surface are provided so as to support a roll of wrapping material therebetween. Each apparatus has an upper frame member which supports an end of the roll thereon and which includes a cavity for dispensing desired lengths of tape therefrom, and a clamp member adapted to be actuated by a user to removably attach its corresponding apparatus to a ledge of the planar surface so that the supported roll is parallel to and above the planar surface.

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.

A vehicle is provided for installing in a prepared area along a ground surface a protective structural support proximate a buried pipeline in an automated manner. The vehicle includes a chassis with a plurality of wheels and a payload release mechanism coupled to the chassis and including a roller for holding the protective structural support. The payload release mechanism is configured to dispense and lay down the protective structural support in the prepared area. The vehicle includes a liquid dispensing mechanism that is coupled to the chassis and is located downstream of the payload release mechanism. The liquid dispensing mechanism includes a liquid source and a dispenser that is in fluid communication with the liquid source and is configured to dispense liquid across a spray area.

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.
