Abstract: A terminal board-cable assembly has an electric supply cable, and a boxlike terminal board molded from synthetic plastic material and defined by a base having at least one electric contact projecting from a first face of the base, and by a cover which is able to be locked to the base against a second face of the base opposite the first base. The cable is inserted and fixed removably fixed inside the boxlike terminal board, and has at least one conducting wire connected to the electric contact. The cover was connected non-removably to the base by at least one screw fitted through the cover, and having the head recessed inside a seat on the cover, and a shank threaded inside a threaded dead seat on the base. The screw is a one-way type, fastener, that is, one having a head with a gripping member only enabling the screw to be rotated in the threading direction, so that the screw, once threaded inside the seat, cannot be unscrewed, thus making the assembly monolithic in the same way as a pressure molded assembly.

A series of integrated upholstering elements are injection molded one at a time in a system featuring two mating half molds, between which the tape and the ties are stretched between respective feed-off reels and gripping devices; after being molded, each integrated element is translated by a sufficient amount to feed a further free portion of the tape and ties between the half molds and the gripping devices, to perform the next molding operation; and the previously molded integrated element is detached by cutting the tape and ties downstream from the gripping devices.

Abstract: A process for moulding a fastener formed from two members arranged one inside the other, in which the two members are moulded from a fluid plastic material within separate moulding cavities of the same mould with the use of a common cylindrical core so as to form the members separate from one another but facing each other axially. Subsequently, while the members are at a high enough temperature so as to ensure their high deformability, the mould is opened by the movement of respective parts forming the lower die so as to release only the first member, and the subsequent withdrawal of the core causes the insertion of the first member into a through-hole in the second member and, finally the core is withdrawn completely from the fastener. The latter is then expelled from the mould.
