Abstract
In some embodiments, a system includes a stamp, a band gear, a bridge, a driver, and a drive unit, in particular an ABU, preferably for a band gear in an impression unit for a stamp (1). The system includes at least an adjustment wheel with a driver, and a so-called bridge. A band is fastened over the driver and around the bridge. When the adjustment wheel is actuated, the band is adjusted via the driver. The driver of the band gear is formed from at least two different materials, in particular a 2C injection-moulded component. The outer component butting against the band or conveyor band, respectively, has a low thickness preferably of less than 1.5 mm, in particular 0.4 to 0.8 mm.
