A method and device for assembling pre-shaped pairs of coaxially mating parts in interfitting assembled relationship one within the other and briefly embodying the concepts of rotating the mating parts in unassembled positionally oriented relationship through a first arcuate path with the corresponding interfitting portions thereof disposed transversely of their respective rotational planes and in adjacent confronting relationship with one another, and concurrently rotating an axially elongated assembly member in rotational synchronization with the mating parts and through a second arcuate path deployed in adjacent oblique planar relationship with the arcuate path of rotation of the mating parts to thereby direct the assembly member to travel along an arcuate path disposed to cause the assembly member to uniformly advance and retreat relative to the arcuate path of rotation of the mating parts and during such advance to forcefully urge the mating parts into assembled interfitting relationship one within the other. The method and device are particularly suitable for the assembly of closure caps with mating, coaxially interfitting members such as insert liners and gaskets, and the concepts involved are also applicable for assembly of closure caps with various other mating, coaxially interfitting members such as, among others, vials, bottles, jars and various other types of containers. Moreover, the structural and operational concepts are especially suitable for utilization in production-line assembly operations for automatically and rapidly assembling a continuous succession of mating and coaxially interfitting parts.
