ABSTRACT:
In order to control the pressing-on time of sealing jaws in the sealing of folding tabs consisting of sealable packaging material, a cam element, of which the cam part or cam body 17 has a cam recess 20 of irregular shape, is used. A sensing member (tracer roller 16) is adjustable relative to the cam element as a function of the working speed of an associated packaging machine, so that different regions of the cam element which guarantee an always constant pressing-on time of sealing jaws 12 take effect.
