ABSTRACT:
A machine for printing letters, numbers, symbols and the like on banding or other flexible material of extended length includes a drive wheel and a printing wheel, as well as pressure rollers for pressing the banding against the two wheels. The drive wheel is driven by the banding as the banding is drawn through the machine, and the printing wheel is connected to the drive wheel through a belt such that the two wheels have the same peripheral velocity. Thus, the printing wheel, which has raised characters around its periphery, rotates as the banding passes over it. The raised characters of the printing wheel further pass over the periphery of an ink transfer wheel, all but a small segment of which is contained within a sealed case of an inking unit. The surface of the ink transfer wheel is pitted, and where that wheel emerges from the case, seals are provided to form a vapor barrier which isolates the interior of the case from the surrounding atmosphere. Within the case an ink pick-up wheel lifts ink from a reservoir at the bottom of the case to the ink transfer wheel, from which the ink is transferred to the raised characters on the printing wheel and thence to the banding. The belt further drives the ink pick-up wheel and the ink transfer wheel. A release mechanism is provided which, when operated, withdraws the pressure rollers from the drive and printing wheels, moves the ink transfer wheel away from the printing wheel, and creates slack in the belt.
