Abstract

Die Erfindung bezieht sich auf eine Pressenanordnung mit einer Pressenform (P) zum Pressen von Pressgut (5) zu einem Artikel (6), aufweisend ein erstes Formteil (1) mit einem Randabschnitt (10), ein zweites Formteil (2) mit einem Randabschnitt (20), einen Artikelraum (3) zwischen den Formteilen (1, 2) und deren Randabschnitten (10, 20), und eine Verstelleinrichtung zum Verstellen des ersten oder des zweiten Formteils relativ zueinander in eine geschlossene Stellung zum Befüllen des Artikelraums (3) mit dem Pressgut (5) und zum Pressen des Pressguts und zum Verstellen der Formteile in eine Stellung zum Entnehmen des gepressten Artikels. Vorteilhaft wird die Pressenanordnung dadurch, dass von außerhalb der Formteile (1, 2) durch zumindest einen Umfangsabschnitt von deren Randabschnitten (10*, 20*) ein Füllraum (S*) mit einem zum Befüllen ausreichend breiten Abstand zwischen deren Randabschnitten in den Artikelraum (3) führt und ein übriger Umfangsbereich der Randabschnitte (10, 20) einen Entlüftungsspalt (S) zum Entlüften des Artikelraums (3) aufweist.

The invention relates to a press arrangement with a press mold (P) for pressing pressed material (5) into an article (6), comprising a first molded part (1) with an edge section (10), a second molded part (2) with an edge section (20), an article space (3) between the mold parts (1, 2) and their edge portions (10, 20), and an adjusting device for adjusting the first or the second molded part relative to each other in a closed position for filling the article space (3) with the pressed material (5) and for pressing the pressed material and for adjusting the molded parts in a position for removing the pressed article. Advantageously, the press arrangement is characterized in that from outside the mold parts (1, 2) by at least one peripheral portion of the edge portions (10 *, 20 *) a filling space (S *) with a sufficiently wide for filling between the edge portions in the article space ( 3) leads and a remaining peripheral region of the edge portions (10, 20) has a venting gap (S) for venting the article space (3).
