Abstract
A circular tool arrangement which includes a circular rim having an inner rim with the circular rim having a plurality of circular seats arranged on a first radius and the inner rim having a plurality of circular seats arranged on a second radius. Tools shaped as either cutting members or creasing members are arranged on the rim and have projections which are engaged in one of the groups of seats and each of the arrangements has a ring provided with concentric grooves for receiving projections on the side of the tool facing the ring. The rings are moved in the clamping engagement by a spring arrangement which can be released by applying axial pressure on the heads of the spring arrangement to shift the ring from a clamping position to an open position to enable removal of the tools.
