Abstract:
A stamping roller (10) for a stamping device has a central supporting roller (12) and stamping dies (24) mutually spaced apart around the circumference of the central supporting roller (12). At least one stamping ring with two marginal sections spaced apart in the axial direction that support at least one associated pressing roller (28) with spacing rings (26) in a defined position is secured to the supporting roller. The size and material of the stamping ring (20) are adapted to the supporting roller (12) so that each stamping ring (20) may be adjusted on the supporting roller (12) at room temperature and fixed by thermal expansion on the supporting roller (12) at the increased stamping or operation temperature of the stamping roller (10). Each stamping ring (20) has a heat insulating part arranged between both lateral spacing rings (26) and between adjacent stamping dies (24). Lateral caps (34) adjacent to each die (20) are provided.
Abstract:
A low-vibration folding device drive for a rotary press is produced in that each drivable rotating part or unit has a separate motor. Here, the motor concerned is positively secured to the corresponding rotating part, e.g. perforating rollers, folding cylinders or longitudinal folding devices. The motors are regulated by means of prior art electrical devices.
