摘要

PROBLEM TO BE SOLVED: To spray glass beads in conformation to various kinds of road mark lines by arranging a glass bead spraying mechanism changeable of spraying width of glass beads on one end part of a receiving plate for receiving the glass beads. ;SOLUTION: A glass bead spraying mechanism 7a is formed of a fixed contact plate 22 having a pair of slit holes 22a and a circularly formed end surface, and a pair of regulating contact plates 25 mounted in such a manner as to be movable in opposition to each other through the slit holes 22a, bolts 23, and nuts 24 to the fixed contact plate 22. When glass bead 14 are sprayed in a small width, the end parts 25b of the regulating contact plates 25 are moved so as to be mutually approached, and then fixed so as to be laid along the round part 22b of the fixed contact plate 22. Thus, glass beads 14 can be uniformly sprayed according to the paint film widths of two kinds or more of road mark lines by one device.;COPYRIGHT: (C)1998,JPO
