A sheet conveyor includes: a holder that detachably holds a sheet roll; a rotation measuring device that measures a rotation amount of the sheet roll; a conveyance roller that conveys a sheet pulled out from the sheet roll held by the holder; a tensioner that is provided between the holder and the conveyance roller and that contacts with the sheet pulled out from the sheet roll toward the conveyance roller; a position detector that detects a position of the tensioner; a motor that generates driving force for rotating the conveyance roller; and a controller that controls the motor. The controller estimates a diameter of the sheet roll based on a conveyance amount of the sheet caused by rotation of the conveyance roller, a rotation amount of the sheet roll measured by the rotation measuring device, and a position of the tensioner detected by the position detector.

Disclosed is a winding method using an air expansion structure, which accurately controls the winding process by preset inflation parameter values and preset winding parameter values, so as to create space for a membrane to contract after winding, that is, to relieve the stress of the membrane, so as to avoid the situation of deviation or innermost side wrinkling during winding of the membrane, and the rewinding procedure is not needed, so that the complexity of the working procedure is reduced.

A device for dispensing rolled items, such as tape. The hand-held or mounted tape dispensing device is designed to accommodate variously sized or shaped rolls of tape. The tape dispensing device for dispensing a tape may comprise a support structure and one or more tape holder sliders configured to be moveable from a first position to at least one second position. The tape dispensing device may also include one or more tape holder sliders, which may move simultaneously in a single direction. The tape dispensing device may also include a tape dispenser blade having a cutting edge and configured to be moveable from a first position to at least one second position and to rotate to a position along the cutting edge at different angles.

A controller includes: an adhesion member position determination unit that determines a position of an adhesion member in a rotation direction of a roll on the basis of the result of detection from an adhesion member detector in a state in which the roll has been rotated by a shaft control unit; and an outer diameter determination unit that determines an outer diameter of the roll in a portion where the adhesion member is positioned, the determination being performed on the basis of the result of detection from an outer diameter detector in a state in which driving of shaft drive sources are controlled by the shaft control unit such that the adhesion member is positioned within a detection range of the outer diameter detector on the basis of the position of the adhesion member determined by the adhesion member position determination unit.

A system is disclosed. The system comprises a roller with a spindle to wind and/or unwind a roll of media, a media advancement sensor to measure the advancement of the media, and a controller. The controller is to control the spindle to rotate an angular displacement, and to determine a calculated media advancement based on the angular displacement and a radius of the roll of media. The controller is also to receive from the media advancement sensor a measured media advancement. The controller is further to detect that a displacement difference between the measured media advancement and the determined media advancement exceeds a predetermined threshold. If the displacement difference exceeds the predetermined threshold a slippage condition is detected.

A double storing and issuing device for two banknotes denomination and/or other flexible documents, for use in an equipment for the automatic processing of banknotes, where each storing and issuing device includes a storage roller, relative motor, at least a transport tape provided for wrapping on the storage roller together with the banknotes. The two storage rollers can share the space between them because the transport tape, tensioned by storage roller motor and feeding-roller, pushing against accompanying rollers strictly follows storage roller diameter. The double storing and issuing device includes an electronic unit for the storage roller motors and relative transport tapes revolution sensors, that provides a device full status as any possible combination of storage roller diameter plus a minimum gap to avoid mechanical reciprocal interferences.
