PERFORATION DEVICE AND SHEET POST-PROCESSING DEVICE PROVIDED THEREWITH
A perforation device includes a shaft, a perforation motor, at least a first perforation portion, at least a second perforation portion, at least a first cam for reciprocating a first perforation blade in the first perforation portion, at least a second cam for reciprocating a second perforation blade in the second perforation portion, a rotation speed detecting portion, a home position detecting portion, and a controller. in second perforation processing in which the shaft is rotated one turn to perform first perforation with the first perforation portion and second perforation with the second perforation portion in sequence, the controller senses, with the rotation speed detecting portion, the rotation speed of the shaft after the first perforation blade penetrates the sheet in the first perforation and, based on the rotation speed detecting, the controller determines the timing of starting braking control in the second perforation and performs braking control.
Winding Device for a Longitudinally Cut Material Web and System for the Controlled Winding of a Longitudinally Cut Material Web
The present invention relates to a device (20) for winding a longitudinally cut material web having multiple longitudinal strips (12) on a plurality of winding tubes (16) to form in each case a wound roll. The device comprises an axle (24) and, mounted on the axle, a plurality of ring-shaped winding drives (22) that are individually controllable in their operating position. Each winding drive (22) forms an external-rotor electric motor and comprises a static interior tube (40) and a rotatable external tube (50). The external tube (50) that is rotatable on the rolling bearings (48) bears, on its interior, a device for providing an excitation magnetic field (52) that forms the external rotor of the electric motor.
Sheet conveying apparatus
A sheet conveying apparatus includes: a plurality of driving parts each connected to one end of corresponding one of a respective plurality of rotating shafts; a first torque adjuster connected to another end of each of the plurality of rotating shafts, the first torque adjuster applying first torque to the plurality of driving parts; a second torque adjuster that applies, to the driving parts, second torque for adjusting the first torque to be applied to the driving parts by the first torque adjuster; and a hardware processor that controls the second torque to be applied to the driving parts in the second torque adjuster in accordance with a number of revolutions of the driving part.
Sheet-fed press
A sheet-fed press includes at least two units embodied as modules. The at least two modules respectively each comprise at least one individual drive, each individual drive being configured as a position-controlled electric motor. At least one of the at least two modules is configured as a non-impact coating module, and the at least coating module is arranged as at least another of at least two modules that is configured as a primer module or as a painting module.
Perforation device and sheet post-processing device provided therewith
A perforation device includes a shaft, a perforation motor, at least a first perforation portion, at least a second perforation portion, at least a first cam for reciprocating a first perforation blade in the first perforation portion, at least a second cam for reciprocating a second perforation blade in the second perforation portion, a rotation speed detecting portion, a home position detecting portion, and a controller. In second perforation processing in which the shaft is rotated one turn to perform first perforation with the first perforation portion and second perforation with the second perforation portion in sequence, the controller senses, with the rotation speed detecting portion, the rotation speed of the shaft after the first perforation blade penetrates the sheet in the first perforation and, based on the rotation speed detecting, the controller determines the timing of starting braking control in the second perforation and performs braking control.
Sheet conveying apparatus and image forming apparatus
A sheet conveying apparatus includes: a plurality of conveyors provided along a sheet conveying direction; a plurality of main driving parts that is respectively provided to the plurality of conveyors and independently drives the conveyors; an auxiliary driving part that drives the plurality of conveyors; and a transmitter that transmits driving force between the plurality of conveyors and transmits driving force of the auxiliary driving part to the plurality of conveyors.
SHEET-FED PRINTING PRESS
A sheet-fed press includes at least two units embodied as modules. At least two of the modules respectively comprise at least one individual drive which is used to transport a sheet through the respective module or through at least one active region of the respective module. At least one of the at least two modules is configured as a non-impact cover module. At least one component of the at least second module comprises at least one drying system or one drying device. The sheet-fed press includes a transport path for transporting the sheets. At least the section of the transport path provided for the sheets, and secured by the non-impact cover module, extends at least essentially flat or essentially horizontally.
