PURPOSE:To reduce noise and remove the danger of a fire by squeezing a fluid tube by a roller intersecting perpendicularly to the longitudinal direction of the tube to supply pressure fluid from one end of the fluid tube and generate transfer thrust for the roller. CONSTITUTION:There is provided an H-shaped flat track 4 having an elongated flat portion 4' and a fluid tube 1 is laid on the flat portion 4'. A roller 2 is placed and pressed on the fluid tube 1 in such a manner as to intersect perpendicularly to the longitudinal direction of the fluid tube 1 to squeeze the fluid tube 1. Fluid supply hoses 6 connected to a fluid supply source are connected to both end portions of the fluid tube 1, so that pressure fluid is supplied to the fluid tube 1 from one of the fluid supply hoses 6 to press the roller with pressure of the fluid 3 and move the roller 2 on the fluid tube 1 while rolling thereon. Further, a transport truck 7 integral with the roller 2 is travelled by the movement of the roller 2. |
