High speed digital printing system and method for continuous web
A high-speed digital printing system includes two unwinding machines for two input coils for a paper web, an input unwinding and splicing installation and a printing station and in which the input installation supplies, in turn, the printing station with the web of the two coils. The system also includes a splicing and rewinding installation with an output cutting and splicing equipment for an incoming web emerging from the printing station and two rewinding machines with two output coils. The output equipment feeds alternatively the rewinding machines with the incoming web by cutting and splicing of a web of the two output coils without stopping printing. An electronic controller switches the functionality of the output cutting and splicing equipment and of the rewinding machines with setting of the output coils as an operating coil and a waiting coil and, viceversa, as a waiting coil and an operating coil.
Device for the production of appropriately configured roll assemblies of expanded aluminium mesh adapted to efficiently fill fuel containers
Device for the production of selectively configured roll assemblies of expanded aluminium mesh (17) adapted to efficiently fill fuel containers and provide suppression of ignition and combustion of the fuel contained therein, comprising a roll (1) of in expanded aluminium mesh at an inlet of the device, a mechanism (5) for providing tensioning of a mesh web (15) flowing from the inlet to the outlet of the device, a mechanism (6) for forwardly moving mesh web (15), a mechanism (7) for transversely cutting a predetermined portion of mesh web (15), a mechanism (8) that securely folds the edge of the transversely cut end of mesh web (15) and a mechanism (10) wherein a mesh roll assembly (16) is set up onto a disc (12c) that rotates to wind a predetermined number of turns of mesh web (15) around mesh roll assembly (16) and provide an end product of roll assembly of expanded aluminium mesh (17).
Device and method for winding up a film at a packaging machine
A device for winding up a film at a packaging machine, the device including a reception mandrel drivable for rotation about a rotation axis and a reception sleeve for the film for being pushed onto the reception mandrel. The reception sleeve may be formed by segments arranged next to each other along a circumference or perimeter of the reception sleeve, wherein neighboring or adjacent segments may be pivotably connected to each other. The reception mandrel may be formed as rigid body having engagement structures that are configured to cooperate with shape features of an inner circumference or perimeter of the reception sleeve, when the reception sleeve has been pushed onto the reception mandrel, so that a rotation of the reception mandrel about the rotation axis causes the reception sleeve to rotate with the reception mandrel.
METHOD FOR ADAPTING AT LEAST ONE WINDING PARAMETER OF A WINDING DEVICE
The invention relates to a method for adapting at least one winding parameter of a winding device during winding of a film web on a winding core, having the following steps:—conveying of the film web along a measuring path between a first driven roll and a second driven roll—increasing of the web tension of the film web between the first roll and the second roll—continuous detecting of the drive parameters of the first roll and of the second roll at least in the form of the torque and the circumferential speed,—determining of a stress-strain diagram from the detected drive parameters—adapting of at least one winding parameter of the winding device on the basis of the determined stress-strain diagram in order to achieve a defined elongation of the film web during winding on the winding core.
UNWINDING OR WINDING ROLLS OF PRINT SUBSTRATE
In one example, a device for unwinding or winding multiple rolls of print substrate includes multiple spindles each to hold a roll of print substrate and a differential operatively connected to one end of each spindle. The spindles are aligned with one another lengthwise along a spindle axis and the differential is to output torque along a differential axis offset from the spindle axis to turn the spindles on the first axis.
Tape cartridge
The disclosure discloses a tape cartridge comprising a first tape roll, a second tape roll, a connecting part, and a pair of gripped parts. A first tape consumed by feed-out is wound around the first tape roll. The second tape roll winds a second tape around an axis extending along the first direction and provided on a downstream side of the first tape roll. The second tape is generated by a feeding of the first tape. The connecting part is provided so as to connect the first tape roll and the second tape roll. The pair of gripped parts extends along the second direction, each respectively provided on either side of the connecting part along the first direction. The gripped part comprises a slip preventing part configured to prevent slipping during gripping on an end of the gripped part in the one side along the second direction.
Roll-Removal Device, Winding Device and Method for Transporting Away a Plurality of Rolls Which Have Been Wound to Completion
The invention describes a roll-removal device by means of which a plurality of rolls which have been wound to completion are transported away from a winding shaft having a displacement device for displacing the rolls relative to the winding shaft, in order to withdraw the rolls from the winding shaft, having a receiving device for receiving the rolls, and having a transfer device for transferring the rolls from the displacement device to the receiving device, wherein the rolls can be rolled freely at least in certain regions, the rolls rolling about their rolling axes.
By means of this device for changing the position of the rolls axes, the roll axes of two adjacent rolls can be moved to an angle of less than 180 degrees in relation to one another.
