摘要： A roller width adjusting device for a divided molding roller has a hollow main shaft journalled at each end to side bearings so as to be rotatable around a rotary axis thereof. The hollow main shaft is connected at one end to a driving source for rotating the main shaft around the rotary axis. A pair of hollow cylindrical roller holders are disposed on an outer periphery of intermediate portions of the main shaft so as to be slidable along the rotary axis of the main shaft. The roller holders may be fixed in any position along the rotary axis by a holding device. A pair of divided type molding rollers are attached to the roller holders, respectively. An adjusting shaft is rotatably disposed in the hollow shaft along its rotary axis. Each end of the adjusting shaft has a screw thread with opposed screw directions. One end of the adjusting shaft has a rotatable handle. By rotating the handle in one direction the interval between divided rollers is increased thus moving the roller holders farther apart; whereas by rotating the handle in the other direction the interval is decreased thus drawing the roller holders closer together. Once in position, the divided rollers are slidably fixed by the holding device such that pipe of that particular size can be manufactured.

摘要： An apparatus for manufacturing a welded pipe. The apparatus includes a cage or cluster roller molding system. In either case, a rotary axis of each roller is slanted counterclockwise or clockwise with respect to a manufacturing line direction of the apparatus. The adjustable positioning of the rotary axis reduces vertical slip caused when the strip of material passes along the contact surface of the roller.
