The bearing 2 is fitted to the hobbin 3 in advance, and after fitting the stop collar to one end of the shaft 3, the bearing 2 on which the bobbin 3 is attached and the discance piece 6 are inserted from the other end of the shaft 1. The expander roll is assembled by sequentially fitting and fixing the comb cylinder 4 over the outer periphery of the bobbin 3 which is thus attached to the shaft 1.

そして、軸1は若干彎曲させられ、ボビン3およびゴム

Further, since a large number of independent annular grooves 7 are provided on the outer periphery of the rubber tube 4 and a large number of through holes 8 are provided in the rubber tube 4 from the inner periphery of the rubber tube 4 to the bottom of the grooves 7, the rubber tube 4 The water that has entered into the rubber cylinder 4 is discharged through the gap between the bobbins 3 and through the hole 8, so there is no risk of harmful run-out vibrations caused by water, and the water that has entered the groove 7 from the hole 8 of the rubber tube 4 is discharged. Since the water is discharged along the groove 8, it is possible to eliminate the influence of the waste water on the material to be treated such as paper.
