  • the forces introduced into the support element via the drive units in particular the reaction forces generated by the pressing forces as action forces, are therefore not introduced into the matrix unit.
  • the matrix unit can thereby be made smaller.
  • the press frame according to the invention may in particular be a pillarless frame in which the vertical spacers do not have to be designed to accommodate high pressing forces. Since the power flow is essentially not over the relatively long columns of a press frame, there is little spring-up of the press. A bending of the press frame and the associated undesirable influences on the press result are largely avoided. In addition, located in advantageously only a few components of the press in the power flow. As a result, only a few component tolerances add up.
