Cleanable punching arrangement

Abstract

In a process for cleaning a punching arrangement for punching out and forming a container bottom from a punching strip, a die is removed from its operational position for the purposes of cleaning and subsequently returned to its operating position. The die remains connected to the punching arrangement via a guiding element when removed from its operational position. The die can be withdrawn along the guiding element out of the punching arrangement. Furthermore, a punching arrangement is described in which the cleaning process can be very easily carried out.
