A foil reel mounting device for supporting a reel of stamping foil in a supporting module. The device includes a support having a recess to receive an axle of the reel of stamping foil. A retaining element mounted on the support and arranged to move between a closed position, in which the retaining element retains the axle of the reel in the recess, and an open position, in which the retaining element releases the axle of the reel from the recess. The retaining element is biased towards the closed position. Also, a supporting module has at least one foil reel mounting device and a stamping machine includes a supporting module or at least one foil reel mounting device. A method for loading and unloading a reel of stamping foil with such at least one foil reel mounting device is also disclosed.

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 coil feeding device and a graphic machine thereof are provided. The coil feeding device includes a roller mechanism for carrying a coiled material, a base mechanism, and a compression rod mechanism. The roller mechanism includes a shaft penetrating through the shaft hole and a tension structure disposed on the shaft. The tension structure includes a first sleeve, a second sleeve and a tapered fixing member. When the first sleeve and the second sleeve are fixed to each other, the tapered fixing member holds the shaft to achieve mutual fixation of the coiled material and the shaft. By providing the second sleeve, the first sleeve and the tapered fixing member that cooperate with each other, the coiled material and the shaft are fastened to each other quickly, thereby improving production efficiency. Through the base mechanism, the coil feeding device is directly used on existing graphic machine for material processing.

An apparatus for replacing a roll of material with a replacement roll of material comprises a loading station and multiple feed stations downstream of the loading station. Each station comprises two legs and a motorized drive assembly extending between the legs. The drive assembly rotates two sprockets and an endless chain surrounding the sprockets inside each of the legs at a station to raise or lower carriages. A roll support extends between the carriages at each station.

Disclosed is an unwinder with system for loading and unloading reels. The unwinder includes a rotating support with a rotation axis and provided with engaging members for engaging the reels. The unwinder further includes a positioning system for loading the reels onto the rotating support and an unloading system for unloading the reels from the rotating support. The positioning system includes a first conveyor for the reels and a pusher configured and arranged to push the reels from the first conveyor towards abutment members defining a pick-up position where the reel is taken by the rotating support. The positioning system and the unloading system are arranged at opposite sides of the rotating support.

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.

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.

An unwinder (1) of rolls (B1, B2) including a bearing structure (3) and two pairs of arms (11A, 11B; 13A, 13B) supported movable on the bearing structure (3). The unwinder further includes a splicing machine (31). The bearing structure (3) includes a base (5) and an upright (7) extending from the base, on which a cross member (33) is supported. The cross member (33) includes an intermediate portion (33A) rigidly bound to the upright (7) and a pair of lateral supports (33B, 33C) adapted to assume at least one operating position and one non-operating position, with respect to the inter-mediate portion (33A) of the cross member (33).

A system for supporting a reel of stamping foil (2) that is mounted rotatably, includes: two flanges (9, 9) connected to the shaft of the reel (2, 2) that is positioned between the flanges, each flange having a rotary shaft extending outward of the reel; two end walls (7, 7) mounted spaced apart on a guide surface (3), each wall end having at least one upwardly oriented notch (10, 10) arranged to receive the shaft of each flange (9, 9); and a brake (13) which cooperates with and slows the rotation of the reel (2).

Method for spatially arranging coils, the method comprising: providing electronic data about an initial storage state, which electronic data contains information about a respective initial diameter of the coils and a respective initial spatial storage position of the coils in a coil store; transporting a selected coil from an initial storage position to a processing machine for processing at least a portion of the sheet metal of the selected coil; sensing a reduced diameter of the selected coil after the portion of the sheet metal has been removed from the selected coil for processing by the processing machine; storing the reduced diameter of the selected coil; transporting the selected coil having the reduced diameter to a depositing storage position which, depending on the reduced diameter, is selected to differ from the initial storage position in a manner that saves storage space; and storing the depositing storage position.
