A reel support assembly (14) for a web material processing machine is described. The reel support assembly (14) comprises a support frame (16) and at least a first support arm unit (34a) having at least one holding stub (40) for mounting a reel (12) on the first support arm unit (34a). Furthermore, the reel support assembly (14) comprises an elevator unit (24) having a support element (26) on which a reel (12) may be placed. The support element (26) is supported on the support frame (16) in a vertically movable manner. Additionally, a hotfoil stamping machine (10) is presented which comprises such a reel support assembly (14). The reel support assembly (14) is arranged at an upstream end of the hotfoil stamping machine (10) with respect to a web travelling direction.

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.

Large rolls of partially overlapping paper sheets which are convoluted onto the cores of reels are stored in one or more rows of compartments in a newspaper printing or bookbinding plant. Two adjoining rows are separated from each other by a track for one or more vehicles which are used to transport empty reels to one or more compartments wherein the sheets are convoluted onto the respective cores as well as to transport loaded reels to unoccupied compartments or to compartments which are adjacent to unwinding units. Conveyors in the form of cranes and/or chain or belt conveyors are used to transfer empty and loaded reels between the compartments of the rows and pairs of similar compartments on the vehicles. A vehicle which transports a loaded reel from the convoluting station to an empty compartment is used to transport an empty reel from such compartment to the compartment at the convoluting station so that the vehicle is put to use during each stage of its movement.

Systems and methods for connecting the films of a first roll and a second roll in a packaging machine. The system includes a cutting device to cut the film of a first roll at a cutting position upstream side of a holding position with respect to a feeding direction toward a former while the film is held by a holding device. The system also includes a robot to move the second roll to a connecting position where a leading end of second roll film overlaps with a film terminal end of the first roll film. The system further includes a connecting device to connect the film leading end of the second roll film to the film terminal end of the first roll film. The robot to move the second roll from the connecting position to a set position after connecting the films, so that the second roll film is tensioned.
摘要:
Expired paper rolls are removed from one unwinding station in a paper processing plant by engaging them with a gripper and transferring them onto a conveyor which can be operated to move expired rolls axially. Each expired roll is rotated about its own axis before the conveyor is set in motion so that the projecting remnant of web is convoluted around the expired roll before the latter begins to move axially. The one unwinding station is adjacent a second unwinding station which receives a fresh roll from a conveyance while the preceding roll is caused to pay out its web at the one station. The supporting arms for the roll at the one station are pivotable between the two stations so that a partly expired fresh roll can be shifted from the second station to the one station prior to conversion of such roll into an expired roll.

An automatic machine includes a load-bearing frame having a base, a vertical side wall, a horizontal wall facing the base, a vertical front wall, defining a machine front with a protruding motor-driven shaft supporting a respective reel of wound material. A plurality of operating stations positioned on the front wall through which a processing path extends along which said material proceeds whilst it is unwound from the reel. A storage unit houses replacement reels is positioned directly associated with the frame close to the shaft. A device picks up reels and positions them on the shaft. The device is positioned directly associated with the frame close to the storage unit. A control unit activates the device in response to a run out signal of the reel present on the shaft.

摘要:
A pit (14) along which a moving platform (15) with a transverse continuous track section (16) is displaceable is arranged at a reel stand (12). Feed tracks (10, 11) and also a plurality of storage tracks (17) in the form of stub tracks and intended for receiving carriages (6) each having a prepared paper reel (5) abut the lateral edge of the pit (14). Further storage tracks (17) are arranged on the opposite side of the pit (14), in each case aligned with one of said storage tracks (17) or a feed track (10, 11). During printing, the carriages (6) parked on the storage tracks (17) are fed as required via the moving platform (15) to the reel stand (12) and the paper reels (5) are mounted in the axis.
