It is known that the cap can be pivoted on all sides via the hinge pin of the bearing shell,
to shift on the punch head in such a way that 5 Due to the inventive arrangement of the cardie cap with a dome-shaped recessed Danish cap hinge on the punch head, the bearing plate rests on a spherical star- the all-round bendability of the cap against peikopf. To connect the two parts, a spring bar arranged in a spherical cap bearing is substantially transverse to the longitudinal axis of the cap. In this way, the position of the cap can also be provided, which can be stored and adapted in the middle in a wide, ab- io extremely developed secondary rock, well-stepped bore of the punch head without inadmissible stress from a ball pushed onto the spring rod becoming effective during the power transmission, is centered in the bore and at the ends in The universal joint is robust and also recesses in the cap side plates to which the cap is attached to connect the stamp to the lying caps. The pivotability of FIG. 15 is suitable, with which the briquetting of fine coal between the cap is avoided in one direction by the special stamp foot and reclining cap, stop wings on the stamp head and on which, in the case of ball bearings, cancels the articulation. Cap and ii. In the other direction due to the play The relatively large surface area of the hinge pin of the spring aoes in the hole and the recess on the cap results in a smaller surface pressure limited. 20 than with ball bearings, which in turn is favorable

Furthermore, cap hinge connections are used for the effects on the cap construction,
spherical mounting of the cap on the punch head The cap is known in a form-fitting manner through locking pins which open the bearing shell and over the bearing shell in spring rods clamped in the fork mounts of the cap with the joint-cap longitudinal direction between the cap and the punch head. The ball head of the cap joint 25 can be arranged in this way by locking pins in the fork pieces of the bearing shell connected to the punch head either on the punch head or on the cap. By this arrangement and by the fact that the cap falling out of its displacement, the restoring force of the spring rods is intended to force the cap to be carried along with certainty when it is screwed in.
