Abstract (en)
[origin: EP1941957A1] The advancing apparatus includes: a pair of displacement grippers (4,7) which run forwards and backwards and by which the material (22) is advanced in an advancing phase; a stationary pair of clamping grippers by which the material is held in a fixed manner in a non-advancing phase; and a control rocker (12) with a control drive which is coupled to one control end of the latter and to which the displacement grippers and clamping grippers are coupled mechanically and their interaction is controlled. The control rocker, clamping grippers and displacement grippers are designed and are coupled to one another in such a way that, in the absence of a supporting or actuating force exerted by the rocker drive upon the control end of the control rocker, both the clamping grippers and displacement grippers are closed.
