摘要

The processing device has a drive head (11) for ejecting a treatment fluid. An automatic switching function transfers the drive head from a position into another position to reverse the movement direction when a predetermined end position has been reached. The drive head is attached to a flexible or bendable supply line (13). An adjustable deflection element (15) deflects a fluid jet (17) exiting the supply line into a direction dependent on the position of the deflection element.
