ABSTRACT:
An agricultural marking device to disperse elongate strips of rolled paper-web material. A vertically orientated, cylindrical supply hopper has a securable lid. The lower portion of the hopper terminates in a conical transition directing web material in the hopper to an output channel. Drive rollers positioned adjacent to the output channel remove the web material from the supply hopper and deliver it through a downstream opening where a spray head is positioned. The spray head controllably directs a liquid spray onto the web material to separate it in the wetted region or dampen it to weight it. The device is secured to a mounting structure for mounting onto preselected portions of a propelling vehicle or an associated material dispensing device to thereby indicate a boundary of a portion of a traversed field by the web material deposited thereon.
