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.
摘要翻译：用于分割成形辊的辊宽度调节装置具有中空主轴，其在每个端部与侧面轴承支承，以便能够围绕其旋转轴线旋转。中空主轴在一端连接到用于使主轴绕旋转轴线旋转的驱动源。一对中空的圆柱滚子保持器设置在主轴的中间部分的外周上，以便能够沿着主轴的旋转轴线滑动。辊保持器可以通过保持装置沿着旋转轴线固定在任何位置。一对分割型成型辊分别安装在滚子支架上。调节轴沿其旋转轴线可旋转地设置在中空轴中。调节轴的每一端都有一个螺纹相对的螺纹方向。调节轴的一端具有可旋转的手柄。通过在一个方向上旋转手柄，分离的辊之间的间隔增加，从而使辊保持器更远离; 而通过沿另一方向旋转手柄，间隔减小，从而将辊保持器更靠近在一起。一旦就位，分离的辊由保持装置可滑动地固定，使得可以制造具有特定尺寸的管。
