The present invention relates to a w winder (1) for winding a web roll (2) from a fibrous web such as a paper web or a web of non-woven material paper (2). The winder (1) comprises two support rolls (3, 4) for supporting the web roll (2) during reeling and a core shaft (5) for winding the paper reel (2). At each longitudinal end of the core shaft (5), there is a carrier chuck (6) in which the core shaft (5) is rotatably journalled. The carrier chucks to are arranged to be movable in a frame towards or away from the support rolls (3, 4) and a rider roll (8) is arranged to be capable of acting against the web roll (2) being wound. The rider roll (8) is carried by a rider roll beam (9) and the rider roll beam (9) is arranged to be movable in the frame (7) such that the rider roll (8) can be moved towards or away from the support rolls (3, 4). There is at least one actuator (10) for moving the rider roll beam (9) towards or away from the support rolls (3, 4); and at least one load cell (12) arranged to detect the force between the rider roll (8) and the web roll (2). The winder (1) also comprises at least one actuator (11) for moving the carrier chucks (6) of the core shaft (5) independently of the rider roll beam (9) and the winder (1) comprises at least one load cell (13) arranged to detect the force with which the carrier chucks (6) act on the core shaft (5). The winder (1) also comprises a logic control system (14) connected to the load cells (12, 13) such that the logic control system (14) receives measured values for the force between the web roll (2) and the rider roll (8) and the force with which the carrier chucks (6) act on the core shaft (5). The logic control system (14) is programmed to control movement of the carrier chucks (6) and the rider roll beam (9) such that the sum of the forces detected from the load cells (12, 13) and the force resulting from a calculated weight of the web roll (2) corresponds to a set value for the force between the web roll (2) and the support rolls (3, 4). The invention also relates to a corresponding method for operating the winder.

The present invention relates to a w winder (1) for winding a web roll (2) from a fibrous web such as a paper web or a web of non-woven 12 material paper (2). The winder (1) comprises two support rolls (3, 4) for supporting the web roll (2) during reeling and a core shaft (5) for winding the paper reel (2). At each longitudinal end of the core shaft (5), there is a carrier chuck (6) in which the core shaft (5) is rotatably journalled. The carrier chucks to are arranged to be movable in a frame towards or away from the support rolls (3, 4) and a rider roll (8) is arranged to be capable of acting against the web roll (2) being wound. The rider roll (8) is carried by a rider roll beam (9) and the rider roll beam (9) is arranged to be movable in the frame (7) such that the rider roll (8) can be moved towards or away from the support rolls (3, 4). There is at least one actuator (10) for moving the rider roll beam (9) towards or away from the support rolls (3, 4); and at least one load cell (12) arranged to detect the force between the rider roll (8) and the web roll (2). The winder (1) also comprises at least one actuator (11) for moving the carrier chucks (6) of the core shaft (5) independently of the rider roll beam (9) and the winder (1) comprises at least one load cell (13) arranged to detect the force with which the carrier chucks (6) act on the core shaft (5). The winder (1) also comprises a logic control system (14) connected to the load cells (12, 13) such that the logic control system (14) receives measured values for the force between the web roll (2) and the rider roll (8) and the force with which the carrier chucks (6) act on the core shaft (5). The logic control system (14) is programmed to control movement of the carrier chucks (6) and the rider roll beam (9) such that the sum of the forces detected from the load cells (12, 13) and the force resulting from a calculated weight of the web roll (2) corresponds to a set value for the force between the web roll (2) and the support rolls (3, 4).

The supply facility comprises a preparation station (32), said preparation station comprising a manipulator arm (70), and at least one motor (53), the preparation station and the unwinder being distinct from the green tire manufacturing machine. The method comprises the following successive operations: loading the reel onto the unwinder; positioning the end of the product wound on the r?el; arranging the end of the product in such a way that it is laid on a dispenser of the unwinder; and transferring the reel from the preparation station to the green tire manufacturing machine.

A printing apparatus includes first and second supplying portions, a printer, and a winding unit. The first supplying portion can supply a recording medium on a conveyance route to the printer for first surface printing. The winding unit then rotates in a first direction to wind the printed recording medium. A wound recording medium edge is located at a specific location and then guided to a conveyance route opening portion if the wind direction is a second direction. After the edge is at the specific location, the recording medium is supplied through the opening portion to the printer for second surface printing. If the second supplying portion supplies the recording medium for first surface printing, then it supplies the medium for second surface printing. If a user sets a wound-in-advance recording medium to the second supplying portion, the second supplying portion supplies the set recording medium to the printer.

According to an embodiment, a printer includes a drop portion that catches, in a case where a diameter of a roll of paper stored in a holder becomes small, the roll of paper that falls from the holder. The printer further includes a plurality of support rollers that are arranged so as to sandwich an inlet of the drop portion and rotatably support the roll of paper PR stored in the holder. At least one of the plurality of support rollers is a short-width roller whose width in an axial direction of a shaft is shorter than a paper width of the roll of paper PR, and a void is provided at a non-shaft arrangement part provided at an extension portion of the short-width roller in the axial direction.

There is provided a printer including, in a sheet holding section configured to hold roll paper formed by rolling a printing target sheet, a pair of pressing sections configured to hold the roll paper from both side ends, and a holding section provided in each of the pressing section. The holding section is displaceable to a first position where the holding section projects to a side opposed to a side end portion of the roll paper and a second position where the holding section does not project. The holding section enters a cylindrical portion in a rolling center of the roll paper in the first position to hold the roll paper.

A feed tray configured to accommodate a roll, in which a sheet-shaped medium is rolled in a roll shape, the feed tray includes: a support portion configured to contact an outer peripheral surface of a lower portion of the roll at two support positions with a lower end of the roll being interposed therebetween and to rotatably support the roll; and a path having an inlet disposed between the two support positions and configured to guide the sheet-shaped medium unrolled from the roll. The two support positions are shifted from each other in an upper-lower direction.

It is disclosed an anti-jamming device for a printing apparatus with stacker, for lottery or betting terminals, with a path of a continuous strip of paper, a printing device for printing a document on the strip, a cutting device for separating the document from the strip, a movement device for moving the document laterally to a stacking zone, a movable portion that bounds the path and is moved from the strip in the event of a jam, moving the portion causing printing to be stopped.
