ABSTRACT:
A bundle of parallel glass tubes (27) is passed through openings (29) in parallel alignment plates (5) which divide the bundle into a central portion (31) in a zone between the two alignment plates and two end portions (33) beyond this zone. Subsequently, the tubes are softened by heating and the central portion of the bundle is constricted. Subsequently, the central portion is embedded in a moulding compound which, when set, forms two coupling pieces (1) for printing heads, which coupling pieces can be separated from one another along a separating plane (37) which extends parallel to the alignment plates. Thus, important parts of at least two printing heads are manufactured simultaneously.
