Abstract
A machine for manufacturing disks on a very long rod, said machine including two conveyor-driven chains of moulding units that press against one another and receive said rod therebetween in an area provided with at least one orifice for injecting a plastics substance into a cavity formed between a pair of mating units, one from each chain, the units then parting to release a disk-shaped part moulded onto said very long rod. At least one of the sets of moulding units has a so-called "hermaphrodite" unit (1) with leading tabs 8 and trailing tabs (10) for fixing to its adjacent units in the chain. The tabs are such that they allow the "hermaphrodite" unit to be inserted between a female unit and a male unit or between two other hermaphrodite units. Applications to manufacturing insulator disks on the central conductor of a coaxial cable.
