The invention relates to a control cam set with a working cam and a recoil cam, in which no bending moment is generated and in which the working roller and the recoil roller can roll with no play. The rotational masses of said set are minimized enabling simple angular displacement in relation to the working cycle and rapid replacement. It is well centered and can be mounted and fixed easily. This is achieved in that the working cam (1) and the recoil cam (2) are embodied as a single unit forming a control cam set that is fitted with front teeth (7).
