摘要

"method of fixing retaining jaws on a machine for the manufacture of heads on elongated bodies, a machine for the manufacture of heads on elongated bodies, a tool ring for fixing preferably elongated bodies and a retaining jaw for the manufacture of heads on elongated bodies". the present invention relates to aspects of fixing retaining jaws (2) in nail making machines, which includes a method, a machine, a tool ring (10) and a retaining jaw (2) for said purposes . the unique aspects of the invention include the fact that the retaining jaws (2) are attached to a tool ring (10) in a way where a number of passively fixed linings (6) are used as well as a number of active linings (8). it is thus ensured that the holding jaws (2) can, eg, be replaced without loosening many other holding jaws (2), and that the holding jaws (2) can be placed very precisely and in a way that is reproducible. it is also ensured that the retaining jaws can be effectively and easily fixed. the passive linings (6) each will provide at least one attachment point from which one or more retaining jaws (2) can be aligned, in a way where the interdependence between the attached retaining jaws (2) is reduced, with this a greater degree of precision is obtained, also when a high number of retaining jaws (2) is involved, and also when the distance between the jaws (2) is identical along the entire circumference of the tool ring (10) .
