Abstract: In an apparatus for reshaping or molding tubular envelopes of fluorescent lamps or the like into an annular form, an improvement in or relating to a pulley-shaped mold assembly is disclosed which assembly comprises a pair of separable mold half sections which, when mated together, define an annular groove around the periphery of the mold assembly around which is wrapped an envelope sufficiently heated to a workable or reshapable condition so as to be shaped into the annular form. The molding head of the apparatus comprises two mold assemblies of the type described so that two envelopes may be simultaneously shaped into an annular form. Each mold assembly is divided into a pair of half sections by a vertical plane at right angles to the axis thereof in such a way that one of the half sections located closer to the other mold assembly has a thickness shorter than that of the other half section so that the distance between the paired heads holding tubular envelopes may be shortened with the resultant reduction in overall dimensions of the reshaping apparatus and annular fluorescent lamp manufacturing machine.

Abstract translation: 在用于将荧光灯等的管状包层重新成型或成型为环形的装置中，公开了一种带轮状模具组件的改进或涉及滑轮形模具组件的组件，该组件包括一对可分离的半模部分， 在模具组件的周边周围限定环形槽，围绕该环形槽将包封充分加热至可工作或可重复状态，以便成形为环形。 该装置的成型头包括所述类型的两个模具组件，使得两个包络件可以同时成形为环形。 每个模具组件通过与其轴线成直角的垂直平面分成一对半部分，使得位于更靠近另一模具组件的半部分中的一个具有比另一半部分的厚度更短的厚度 使得保持管状信封的成对头部之间的距离可能缩短，从而导致整形装置和环形荧光灯制造机器的整体尺寸的减小。
