A printer includes a transportation unit that transports roll paper, a winding unit that winds up the transported roll paper, and a controller that controls the transportation unit and the winding unit. The controller switches between thresholds for a torque limit of the winding unit on the basis of inertia of the winding unit and a speed at which the roll paper is transported when the winding unit winds up the roll paper in synchronization with a transportation operation of the transportation unit.

A printing apparatus includes a transport unit which includes a transport roller pair which transports a medium in a transport direction, a printing unit which prints onto the medium, a winding unit which winds the printed medium, and a tension application unit which applies a tension to the medium at a position between the transport roller pair and the winding unit. The tension application unit includes a pair of arms which are capable of rotating. A tension bar is supported on one end of the arms and comes into contact with the medium. The bar is rotated from an upper limit position to a lower limit position by transportation of the transport unit being performed two or more times.

The invention relates to an assembly for handling a string of medicament pouches, wherein the assembly comprises a packaging device for packaging discrete medicaments in the respective medicament pouches, and a winding device for winding said string on a reel, wherein the assembly further comprises a control unit which is operationally connected to the packaging device and the winding device, wherein the control unit is arranged to: receive one or more packaging status signals from the packaging device and to send one or more winding control signals to the winding device in response to said one or more packaging status signals; and/or receive one or more winding status signals from the winding device and to send one or more packaging control signals to the packaging device in response to said one or more winding status signals.

A method and apparatus for the production of coreless paper rolls, including a winding phase on a central spindle of a paper web carried out by a main reel, until the formation of a wound paper roll, a phase of extraction from the wound roll of the spindle by application of a relative axial extraction force between the roll and the spindle, where the winding phase includes a first winding phase of a number of web revolutions on the central spindle performed at a first winding tension that is lower than the next winding tension.

A sheet conveyance apparatus includes an acquisition unit that acquires information indicating a peeling position where a protective film is peeled off a sheet, and a control unit that controls a roll device based on the information and moves the peeling position.

Embodiments relate to a jelly roll winding unit (1) and winding method for a secondary battery and, more particularly, to a jelly roll winding unit (1) and winding method for a secondary battery seeking to prevent sagging in the width direction by constantly supporting the bottom of a jelly roll (J) during the work of wrapping the jelly roll (J) with a separator (B) and easily guides the folding line of the separator (B) as needed.

A rope tensioner which includes a take-up reel and a take-up spring. A damping assembly is configured for the take-up reel and includes a follower gear, a damping gear and a damping removal component. The follower gear is configured to rotate synchronously with the take-up reel. The damping gear is movably configured and keeps in damping engagement with the follower gear. The damping removal component is movably configured, and when an external force for removing the damping engagement is applied to the damping removal component, the damping removal component promotes the damping gear to disengage from the follower gear to relieve or remove the damping engagement. The situation where a hook rebounds under the action of inertia when a rope is taken up and hits against products and even causes injuries to users is avoided.
