ABSTRACT:
A folding machine for processing printed sheets has a folding pocket into which sheets are fed by a pair of rollers. The infeed of the folding pocket has a guide plate and a guide device between which sheets are guidingly fed into the pocket. The guide device consists of a succession of several profiled segments releasibly secured to a carrier, preferably slidingly mounted in a groove in a carrier by means of clamping screws. The profiled segments may be spaced from one another so as not to contact adhesive strips on the sheets. Because guide device consists of several segments, the spaces between segments can easily be varied to match sheets having different formats of adhesive strips.
