PROBLEM TO BE SOLVED: To uniform the distribution of a precoating agent in the pipe of a carrier piping in adhesive material collection equipment.SOLUTION: Tube parts S1, S2, S3, S5 and S6 for dispersion extending in a direction of an outlet central axis core are disposed at the outlets of refraction tube parts K1 and K5 or the outlets of branched pipe parts K2, K3 and K6 in a carrier piping 23. In the tube parts S1, S2, S3, S5 and S6 for dispersion, diameter reduction tube parts x1, x2, x3, x5 and x6 whose diameters of an internal flow channel are gradually reduced toward a conveyance direction downstream side, and straight tube parts z1, z2, z3. z5 and z6 in which an internal flow channel has the same core disposition with the outlets of the diameter reduction tube parts x1, x2, x3, x5 and x6 and extends in a straight shape are aligned formed from the conveyance direction upstream side by this order. |
