Abstract: A striper (10) has a spring-loaded striping head (30) which connects with a reservoir (16) only when the head (10) is depressed by contact with a workpiece, and which does not feed paint or other striping material at any other time. A long, closely fitted tube (31) minimizes leakage and has a side opening (32) to valve stripe material. The parts are readily disassembled but are firmly held when assembled, for ready cleaning and replacement of worn parts. The reservoir (16) is preferably separate for each head (30), and separately fed for any striper head (30) or group of striper heads (30) to produce the desired pattern of stripes. The striper heads 30 may be of interchangeable widths. A stop 13 is the only part retaining all heads.
