The unwinder includes an unwinding station, in which to arrange a reel to be unwound. In the unwinding station there is arranged a series of guide rollers, defining a feed path of the web material. There are also provided: a cutting member adapted to cut a web material coming from an exhausted reel, and splicing members, to splice a trailing edge of a first web material coming from an exhausted reel to a leading edge of a second web material coming from a new reel. A pick-up device is configured to pick up the leading edge of the second web material from a temporary retaining element, carried by a transfer unit to transfer reels to the unwinding station.

A sheet supply device that supplies a sheet from a roll, includes: a first roll support portion which rotatably supports the roll on one end side in a width direction of the roll; a second roll support portion which rotatably supports the roll on the other end side of the roll by opposing the first roll support portion; and a guide portion which extends in the width direction and movably supports the second roll support portion in the width direction; wherein below a first space in which the roll between the first roll support portion and the second roll support portion is installed, a second space into which a cart which transports the roll enters is formed.

A recording apparatus includes a containing portion that contains a rolled sheet obtained by winding a sheet and a recording portion that records an image on the sheet fed from the rolled sheet contained in the containing portion and further includes an opening/closing member that can be movable between an open position at which the containing portion is opened and a closed position at which the containing portion is closed and a first guiding portion provided in the opening/closing member to guide the rolled sheet to the containing portion in a case where the opening/closing member is at the open position.

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

A base paper roll supply device includes: a first stand rotatably supporting a rear-liner base paper roll and a rear-liner replacement base paper roll; a second stand rotatably supporting a core base paper roll and a core replacement base paper roll; and a third stand rotatably supporting a front-liner base paper roll and a front-liner replacement base paper roll. The first stand, the second stand, and the third stand are arranged in order along a supply direction in which the rear liner, the core, and the front liner are supplied. At the first stand, the rear-liner replacement base paper roll is arranged at an upstream side in the supply direction with respect to the rear-liner base paper roll, and at the third stand, the front-liner replacement base paper roll is arranged at a downstream side in the supply direction with respect to the front-liner base paper roll.

A device for moving reels, including at least one supporting upright associable with a transport vehicle, and at least one head for manipulating the reels connected to the support upright; the manipulation head includes at least one first grip member, provided with a first terminal element adapted to grasp the reel at a first opening of its central through hole.

A printer includes a case including an input port for rolled paper, a cover provided to be rotatable between a closed position of the input port and an open position of the input port, a holding portion that holds the rolled paper, a biasing member that biases the holding portion in a first direction, a stopper mechanism that stops rotation of the holding portion in the first direction, and a linkage mechanism that rotates the holding portion in conjunction with the rotation of the cover. When the cover is in the closed position, the holding portion rotates in the first direction in accordance with an outer diameter of the rolled paper by a biasing force of the biasing member. When the cover rotates from the closed position to the open position, the holding portion rotates together with the cover against the biasing force of the biasing member.

The invention relates to a corrugated board system, comprising at least one intermediate web dispensing device for dispensing at least one intermediate web, at least one cover web dispensing device for dispensing at least one cover web, at least one corrugated board production device arranged downstream of the at least one intermediate web dispensing device and cover web dispensing device for producing at least one corrugated board web laminated on one side from the at least one cover web and intermediate web, a laminating web dispensing device for dispensing a laminating web, a connecting device for connecting the at least one corrugated board web laminated on one side and the laminating web to one another upon formation of a corrugated board web laminated on both sides, at least one transport carriage for transporting at least one material roll along at least one movement path between at least one material roll store and the at least one intermediate web dispensing device, cover web dispensing device and/or laminating web dispensing device, and a control device for actuating the at least one transport carriage.

A processing line processes logs of convolutely wound web material and has upstream and downstream sections. A main accumulator has buckets that receive, hold, and release logs. An input feeder receives logs from the upstream section and conveys them to a bucket of main accumulator. A loader has a loader accumulator and loader buckets that receive, hold, and release logs. A transfer conveyor between the main accumulator and the loader receives a log from the main accumulator bucket and conveys the log a loader bucket independently of the input feeder. The loader receives a log from the transfer conveyor. The loader conveys the log in the loader bucket to a discharge of the loader. The loader discharge discharges the log from the loader bucket to the downstream section of the processing line.
