Moulding and fitting-together system

1) System for moulding and fitting together a first part and a second part, for example of the type consisting of the lid and body of a cap, the moulding and fitting-together system comprising:

• two guide rails extending parallel to a first direction,
• for each guide rail, a carriage mounted so as to be able to move in translation on the guide rail,
• for each carriage, a cam carrier able to move in translation with respect to the said carriage parallel to the first direction and having a cam, the two ends of which are distant from each other in a fitting-together direction perpendicular to the said first direction,
• an assembly bar carrying a series of first cavities, each first cavity being intended to mould one of the first parts, each end of the assembly bar being mounted in one of the two cams,
• a series of second cavities, each second cavity being intended to mould one of the second parts,
• an activation device designed to move the cam carriers, and
• for each carriage, a locking device designed to lock the said carriage alternately with the cam carrier and the guide rail,
• the assembly bar being firstly able to move in translation parallel to the first direction between a first position in which the first series of cavities is not opposite the series of second cavities and a second position in which the first series of cavities is opposite the series of second cavities, and secondly, from the second position, able to move in translation parallel to the fitting-together direction, between a distant position in which the first part and the second part are not fitted together and a fitting-together position in which the first part and the second part are fitted together.
