A paper rewinding machine includes a rewinding assembly operable to produce coreless retail paper rolls.

A measuring device is releasably received within a winding core of a customer roll wound on a slitter-winder (10). The measuring device (20) is releasably fastened within the winding core by fastening element(s) (21) securing the device to the winding core (10) for rotation during winding of the fiber web around the winding core to form the customer roll. Eccentricity of the customer roll as it is wound is determined from movement, speed and/or acceleration data received from at least two sensors of the measuring device and data is stored for use in unwinding the fiber web from the customer roll and serving as control information. Tension variations in unwinding can thus be anticipated and premeditative steps taken to ensure smooth running of the fiber web in unwinding in further processing.

Rewinder for making paper logs, including a winding station with a first winding roller and a second winding roller delimiting a nip and a third winding roller downstream of the other rollers. The rewinder includes optical elements for detecting, at a predetermined time, an actual position of each log in said winding station and an electronic unit connected to the optical elements and programmed to compare the actual position with a theoretical position of the log at the time, the electronic unit being connected to at least one motor driving the rollers and programmed to modify the speed of the at least one motor when a deviation between the actual and theoretical positions exceeds a pre-established value, the electronic unit being also programmed to operate said optical elements at the time.

A log roll can be efficiently manufactured in a log roll manufacturing apparatus. When yet-to-be-wound base paper constituted of stacked sheets of first base paper and second base paper fed from first and second parent rolls is supplied to a main processing-winding unit, if a winder capable of manufacturing a two-ply log roll and including a sub processing-winding unit is to manufacture a one-ply log roll by using the main processing-winding unit, the yet-to-be-wound base paper constituted of the stacked sheets of the first base paper and the second base paper is separated into first separated yet-to-be-wound base paper and second separated yet-to-be-wound base paper by a base-paper separating unit. Then, one-ply log rolls are simultaneously manufactured by using the main processing-winding unit supplied with the first separated yet-to-be-wound base paper and the sub processing-winding unit supplied with the second separated yet-to-be-wound base paper.

A printer includes a print head, a platen roller facing the print head, a driving source, a drive shaft connected to be driven to the driving source and rotatable about a rotation axis thereof, a platen gear connected to be driven to the platen roller, and a cassette mounting portion at which the print head and the drive shaft are disposed. A printing cassette including a to-be-printed tape, an input unit, and an output unit connected to be driven to the input unit is mountable on the cassette mounting portion in an axial direction of the rotation axis of the drive shaft. In a state where the printing cassette is mounted on the cassette mounting portion, the drive shaft is engaged with the input unit and the platen gear is engaged with the output unit.

A printing apparatus (printer) is provided in which a base material is conveyed by a roll-to-roll method and feedback control is performed on a tension imposed on the base material, and which includes a control unit, a first drive motor (front drive motor) configured to control a speed of conveyance of conveying the base material, and a second drive motor (feeding motor, rear drive motor, winding motor) configured to control the tension imposed on the base material. In a case where a conveyance operation for conveying the base material is stopped based on detection of a foreign object, and when a speed of the first drive motor is at a predetermined value or less, the control unit stops the tension control performed by the second drive motor.

An apparatus for manufacturing a display device includes a first roller from which a film member is unwound, a second roller around which the film member is wound, a flatness maintainer that is arranged between the first roller and the second roller and keeps at least one of an upper surface and a lower surface of the film member, flat, and a sensing unit arranged on at least one of the upper surface of the film member and the lower surface of the film member and detecting droplets dropped from a head unit onto the film member.
