First of all, the filling shoe (not shown) moves over the mold plate 1 and fills it with the PreSpulver up to your upper band. Then the upper punch 18 goes down and compresses the press pulley 19 "As the compression of the powder between the upper punch 18 and the rope β progresses, the rope 6 gives way due to its resilient mounting downwards bus ₉ during the lower punch 13 its The position of the upper punch 18 _{9 is} smaller on the iell S ^ JaT ^ o than the stroke of the upper punch 18, based on the Uhterstearpel ^ f and swar the egg body difference is equal to the clear distance between the lower edge of the file 6 IMD the lower itosehlag 15 for iell 6 _e Once the ISatesrkante of parts © 6 to the stop 15 meets atatfV ₈ is a further © Iurückfedern of the part 6 is no longer possible. The upper punch 18 now completes its eating stroke, with an exact distance in the vertical direction between the lower punch 13 and the upper punch 18 as well as between the upper punch 18 and the rope 6

As a result of the stop 15, the result is that the exact PreE-maS is secured in the press belt * -After pressing has taken place, the upper punch 13 gives Euriicls: At the same time , the terstesjpel 13 is inevitably moved in the well-known quiet way above the wheel pushes the The resulting pils-shaped core is pushed out upwards. The part S springs back again into a rare o1> ere greasy position and accordingly supports the ejection of the pressed part in a certain way. As soon as the overfcmte of the "SaterstempeXs 13 is aligned with the upper edge of the HOtm * plate 1 *, the molding is pushed away * by means of the filling shoes that push the mold again, and the game mdederhol't eicb yoii new»

It is understandable that in the Afcfc # i waä Z as well as in the following sections, the position of the resilient ropes shown with full lines represents their upper limit position , while the one shown in dashed lines.

It will be seen * that care is taken in this manner _g that the rel © Tite Füllh8he ₉ d »h _e the filling height beaegea to the height of the finished compact _t at the point concerned s © can be chosen to be at all points of the form is the same size »This results in an even distribution of the individual files, nasty compacts, without the need for the material to flow through the pressure equalization.

The same effect as when pressing moldings on both sides, in that the punch 15 is relative to the vertical ones Walls of parts β and 12 migrates to Olsen · This also increases the evenness of the ß-efuges -and the JüöglicbJceit created ^ 5eü <s with considerable length expansionxages in the PreBriehtung au press »
