<p>Apparatus for the frontal introduction of marking strips (24), which are automatically formed, into a sheet stack (26) comprises a strip feeding device (18, 74-90) for supplying the marking strips (24) from a supply roll (20); a tongue (36) which is moved frontally into the sheet stack profile, lowered onto the stack (26), raised again and then retracted from the stack under the next deposited sheet (100); a guide channel (90) for the strip (22) supplied by the strip feeding device which opens into a gap under the lowered tongue (36); and a severing device (92) for severing the introduced marking strip (24) from the strip supply. The tongue (36) has downwardly bent flanks (40) that form a flat wedge, the guide channel (90) thereby opening into the channel (42) inside the tongue. The tongue is retracted in a loop-like movement while it is being slightly raised. It is then lifted upward before being moved in again while, for the most part, remaining outside the stack profile. The subject apparatus may be used on the front side (the side opposite the sheet supply side) of a stacker (6) having guide belts (28) running over it which leave little free space above the stack.</p> |
