ABSTRACT:
Device suitable for removing test sheets from sheet-fed printing presses includes leading-edge stops for a downwardly directed sheet stream, the stops being pivotable by a stop lever, and catch arms articulatedly connected to catch levers, the catch arms being adjustable by a tilt lever from outside the sheet stream into a catch position therewithin, as well as a spring engaging with the stop lever, the leading-edge stops being pivotable against the action of the spring out of a stop position and into a release position after the catch arms have reached the catch position thereof. This follow-up control is realized by a linearly adjustable adjusting member with a cam and a sliding block which is maintained in continuous engagement in a slot or coulisse formed in the tilt lever, while the cam is maintained in alternating operating connection with the stop lever and a spring leg of the spring which is formed as a leg spring.
