摘要： In order to provide a substrate such as an optical preform rod (24) which is suitable for insertion into a tube and which has a transverse cross section that is substantially circular and disposed concentrically about a longitudinal axis of the substrate substantially along its entire length, a force-applying means such as a graphite roller (52) is adapted to be moved incrementally toward an axis of rotation (35) about which the preform rod is turned rotatably. Movement is discontinued when there is an indication that the force-applying means has been in continuous engagement with the preform rod for at least a predetermined portion of the periphery of the rod. In a preferred embodiment, the engagement of the force-applying means and the preform rod is discontinued after a predetermined time whereafter the force-applying means again is moved toward the axis of rotation. Cycles of engagement and disengagement are continued as relative motion is caused between the force-applying means and the preform rod in a direction along the axis of rotation.

摘要翻译：为了提供诸如光学预成型棒（24）的基底，其适于插入管中，并且具有基本上圆形并且基本上沿其整个长度围绕基底的纵向轴线同心地布置的横截面，诸如石墨辊（52）的施力装置适于逐渐地朝向旋转轴线（35）移动，预成型杆绕其旋转地旋转。当指示力施加装置已经与杆的周边的至少预定部分已经与预制棒连续接合时，停止运动。在优选实施例中，在预定时间之后停止施力装置和预制棒的接合，然后再施力装置朝向旋转轴线移动。在施力装置和预制棒之间在沿着旋转轴线的方向上产生相对运动的情况下，继续进行接合和分离的循环。

摘要： A preform tube (31) is caused to be collapsed into a preform rod by causing a heat zone (54) provided by a torch assembly (50) to traverse the tube longitudinally in a plurality of passes. During this so-called collapse mode, a muffle tube (100) encloses that portion of the tube which extends through the torch asembly. Advantageously, the muffle tube projects a predetermined distance beyond one major face of the torch assembly. The torch assembly comprises annular semi-circular end plates and an annular semi-circular center portion having a plurality of exit ports through which gases are directed into engagement with the tube. The center portion is caused to be recessed between the end plates thereby causing the heat zone generated by the gases to be narrowed. The narrowing of the heat zone and the substantial confinement of the heat energy within the muffle tube cooperate with increased gas flow rates to cause the tube to be collapsed in a time period which is substantially less than that achieved by prior art methods.

摘要翻译：通过使得由炬组件（50）提供的加热区（54）以多个通过纵向横穿管，使预成型管（31）塌缩成预制棒。在这种所谓的塌缩模式期间，马弗管（100）包围延伸穿过炬组件的管的该部分。有利地，马弗管延伸超过割炬组件的主要表面的预定距离。火炬组件包括环形半圆形端板和具有多个出口的环形半圆形中心部分，气体通过该出口连接到管中。导致中心部分在端板之间凹陷，从而导致由气体产生的热区变窄。加热区的变窄以及马弗管内的热能的实际限制与增加的气体流速协调，导致管在相当于现有技术方法实现的时间段内崩溃。
