A label dispenser coupled to product-transporting carts at retail facilities includes a label roll support arm supporting multiple label rolls thereon, a label guide arm including openings that permit a leading portion of the backing substrate of a label roll to pass therethrough, and a side wall interconnecting the label roll support arm and the label guide arm. The label guide arm also includes an upper portion located above the openings and configured to support the backing substrates of the label rolls thereon. The label guide arm further includes an edge configured to facilitate separation of a leading peelable label from the backing substrate in response to a force applied by the user when pulling the leading portion of the backing substrate of the label roll through the opening of the label guide arm.

A bag dispenser includes a frame with a roller portion for receiving a bag roll defined by a plurality of bags attached to a leading bag to be dispensed, the roller defining a longitudinal axis. A brake plate is configured to capture the leading bag against the frame for providing frictional force on the leading bag to limit sliding thereof, the brake plate pivotally attached to the frame via a pivot arm, the brake plate pivotable with respect to the frame between a non-pivoted friction-application position and a pivoted bag roll-installment position, the pivot arm configured to pivot with respect to the frame along a pivot plane generally perpendicular to the longitudinal axis.

A dispenser (101) for use in applying a protective barrier layer to a surface or structure using single-handed application. The dispenser (101) comprises a spindle portion (103) and a roller mount element (107), each supported by an end cap (102) and having a free end (105, 109). An application surface (111) of a roller (108) rotatable around the roller mount element (107) is resiliently deformable or deflectable for enabling a user to urgingly apply a load to dispensed material as it is being applied to the surface or structure. Dispensing apparatus (1001) comprises the dispenser (101) and protective barrier layer unit (301) comprising a roll of a layer of material (303) for dispensing by the dispenser (101).

A mandrel includes a shaft that can hold a supply roll of film. A primary button and one or more secondary buttons are located on the shaft. The primary button and the one or more secondary buttons are biased toward an extended position and are capable of moving to a retracted position. The primary button and the one or more secondary buttons retract to the retracted position during at least a portion of loading the supply roll of film onto the shaft. The retraction of the primary button to the retracted position causes retraction of the one or more secondary buttons to the retracted position. When the supply roll of film is in an aligned position on the shaft, the supply roll of film is maintained in the aligned position in part by one of the primary button and the one or more secondary buttons in the extended position.

A tape dispenser providing a dispensing assembly adapted to accommodate various widths of tape, wherein the dispensing assembly is operatively associated with a handle assembly to enable self-alignment of the dispensing tape and the dispensing assembly, and wherein a cutting assembly is operatively associated with the dispensing assembly for selectively cutting the dispensing tape.

A media roll holder assembly for a roll is detachably supported in a printing system. A rotational drive includes a roll engaging element configured for fittingly engaging and driving a drive engaging element of a roller, for example an Oldham coupling. A first guide surface is configured to support and direct the roller in a loading direction. A second guide surface at least partially extends at an angle with respect to the first guide surface, such that movement of the roller over the first guide surface brings the drive engaging element in contact with the second guide surface. The second guide surface directs the drive engaging element into a predetermined orientation, which orientation aligns the drive engaging element with the roll engaging element in a loading orientation, such that further movement of the roller in the loading direction inserts the drive engaging element into the roll engaging element.

A mandrel includes a shaft that can hold a supply roll of film. A primary button and one or more secondary buttons are located on the shaft. The primary button and the one or more secondary buttons are biased toward an extended position and are capable of moving to a retracted position. The primary button and the one or more secondary buttons retract to the retracted position during at least a portion of loading the supply roll of film onto the shaft. The retraction of the primary button to the retracted position causes retraction of the one or more secondary buttons to the retracted position. When the supply roll of film is in an aligned position on the shaft, the supply roll of film is maintained in the aligned position in part by one of the primary button and the one or more secondary buttons in the extended position.

A spindle mechanism of a winding machine includes a spindle box provided with a mounting hole; bearings respectively arranged at both ends of the mounting hole of the spindle box to form a front bearing and a rear bearing, the bearing comprises an inner ring and an outer ring; and a spindle, the spindle is arranged to pass through the mounting hole of the spindle box and is rotatably positioned on the spindle box by means of the bearings, and the number of the front bearings is the same as the number of the rear bearings, and the outer ring of at least one of the front bearing and the rear bearing is not restricted in an axial direction so as to form a free end.

A bag dispenser includes a frame with a roller portion for receiving a bag roll defined by a plurality of bags attached to a leading bag to be dispensed, the roller defining a longitudinal axis. A brake plate is configured to capture the leading bag against the frame for providing frictional force on the leading bag to limit sliding thereof, the brake plate pivotally attached to the frame via a pivot arm, the brake plate pivotable with respect to the frame between a non-pivoted friction-application position and a pivoted bag roll-installment position, the pivot arm configured to pivot with respect to the frame along a pivot plane generally perpendicular to the longitudinal axis.

A roll conveyance device includes a transportation device including a roll holding shaft extending in a predetermined direction from a distal section of an arm to hold a roll such that the roll holding shaft is inserted into a core member of the roll; and a mounting section within a moving range of the roll holding shaft, the mounting section allowing the roll to be mounted in a state in which both axial ends of the core member of roll are open. The transportation device is configured to mount the roll on the mounting section, the roll holding shaft is to be pulled out from the core member of the roll mounted on the mounting section to a first side of an axial direction of the core member, and the roll holding shaft is to be inserted into the core member from a second side of the axial direction.
