! Press head to a briquetting press

Briquetting presses for loose materials are also equipped with a free line, in which pre-pressed materials are pressed into briquettes by a piston which is marked in it. sufficient strength by narrowing the outlet opening of the press cylinder. This al mounted in the treeeaylinder a door-all "narrowing opposes the au pressed fabric and de" plunger a Wideretand, eu briquette "is pressed together by larger or smaller resistance through the fabric. But the diversity, the supressing substances and the degree of prepreparation, a different often insufficient or too high pressure is caused by the gnawing cylinder, so either briquettes that are too loose are formed, or the 4-piston finds too high a resistance, which "causes a standstill or In terms of the machine, a constant narrowing of the press cylinder is unsuitable and disadvantageous.

This »deficiency is remedied by the new crimping head after registration. The new crimping head consists of one on the press »y lind er ϊ & βχ ,,. | £ ikett ^ ff |> resj «_ f ^^ e'lfs ^ ii ^ thread sleeve, in it underneath - '!

The new pressing head consists of a sleeve 1 which is attached to the outlet end of the feeding cylinder 0 "The sleeve 1 can be provided at its outlet end with a guide part 2 for the briquettes Diameter approximately corresponds to that of the press cylinder bore.

The mode of operation of the pressing head consists in that the clamping jaws ~ '5f 4 can be adjusted to a smaller diameter than the bore diameter of the frees cylinder 0 by means of the pressure screws 6 and the clamping device D.
