ABSTRACT:
The serrated end portions of the barrels of catamenial tampon inserters are permanently deformed into a substantially hemispherical shape by applying heat and pressure thereto in depressions provided at the periphery of a container which accommodates a confined body of liquid, such as silicon oil, and a heating device which maintains the temperature of the body of liquid within a predetermined range. The heating device includes an electric heater which extends only over a part of the trajectory of movement of the deforming depressions. The barrel preforms are supplied to alternate depressions of an odd number of depressions and the final assemblies are discharged only after they have completed more than a full circle about the axis of rotation of the container.
