A roll-shaped medium transport device includes: a medium supply unit that keeps a roll body formed by winding a roll-shaped medium on a support shaft, and unwinds and supplies the roll-shaped medium; a transport unit that transports the roll-shaped medium unwound from the roll body; a rotation detecting unit that detects rotation of the support shaft; a rotation unit that rotates the support shaft; and a determination unit that determines abnormality of a transport state of the roll-shaped medium on the basis of the rotation detecting unit when the rotation unit rotates the support shaft, when the rotation detecting unit does not detect the rotation of the support shaft in a state where a transport operation of the roll-shaped medium is performed by the transport unit.

A house wrapping device to connect to a wall of a building, the house wrapping device including a main body having an elongate shape, a wrap receiving rod perpendicularly disposed away from a first end of the main body with respect to a direction to receive a house wrap roll thereon and dispense a house wrap from the house wrap roll, and a wedge perpendicularly disposed away from a second end of the main body opposite to the first end with respect to the direction to removably connect the main body to the wall and prevent the main body from falling off the wall.

A feeding unit for feeding a plastic film in packaging machines for wrapping paper rolls, including: a unit for unwinding the film from a reel; a cutting device adapted to cut the film transversely; a transfer device including, on the right and on the left side of the feeding unit, drive belts configured for engaging the upper and lower faces of the film; and a positioning device including, on the right and on the left side of the unit, a predetermined number of drive belts configured for engaging the upper and lower faces of the film. On each side of the feeding unit, the transfer device comprises two pairs of belts. On each side of the feeding unit, the positioning device comprises a third pair of belts. The three pairs of belts are actuated by independent actuators.

A dispenser for dispensing sheet product is provided. The dispenser includes a housing with an outlet through which sheet product is dispensed. A knife drum is rotatable with respect to the housing. A knife is movable between a retracted position within the knife drum and an extended position where the knife protrudes outside of the knife drum to cut the sheet product. A cam follower surface is fixed with respect to the housing. A cam follower is attached to the knife and operable to engage the cam follower surface and travel therealong to transition the knife between the retracted position and the extended position. A spring assembly biases the knife drum during rotation toward a predetermined position. The spring assembly comprises a first spring and a second spring. The spring assembly is attached at a single mount position that is fixed with respect to the housing.

An unwinder (1) of rolls (B1, B2) including a bearing structure (3) and two pairs of arms (11A, 11B; 13A, 13B) supported movable on the bearing structure (3). The unwinder further includes a splicing machine (31). The bearing structure (3) includes a base (5) and an upright (7) extending from the base, on which a cross member (33) is supported. The cross member (33) includes an intermediate portion (33A) rigidly bound to the upright (7) and a pair of lateral supports (33B, 33C) adapted to assume at least one operating position and one non-operating position, with respect to the inter-mediate portion (33A) of the cross member (33).

A dispenser for dispensing sheet product is provided including a housing that defines an interior configured to accommodate a source of sheet product and an outlet through which the sheet product is dispensed. The dispenser also includes a first roller that is rotatable and disposed in the housing. A portion of the sheet product is designed to be in contact with the first roller prior to being dispensed through the outlet. The dispenser also includes a knife drum that is rotatable and configured to cooperate with the first roller to dispense the sheet product. The knife drum includes a knife configured to cut the sheet product into individual sheets. The dispenser also includes a spring assembly that may be configured to bias the knife drum toward a predetermined position during rotation of the knife drum.

An upper-side conveyance guide of a temporary holding section is provided with an upper-side movable guide that capable of moving in coordination with the drum diameter of a drum so as to be interposed between the upper-side conveyance guide and the drum at all times. The upper-side movable guide guides a banknote that is being conveyed gripped only at the center by a banknote conveying portion of a main tape, between the upper-side conveyance guide and the drum. Folding of the banknote is accordingly suppressed by the upper-side movable guide, enabling the banknote to be guided to a gap between the upper-side conveyance guide and a lower-side conveyance guide without catching on a rear face of the upper-side conveyance guide or the like. Accordingly, the banknote can be prevented from contacting portions that should not be contacted and causing conveyance issues as a result.
