Abstract
In a multi-bobbin machine for making paper booklets e.g. of interleaved cigarette paper, a multiplicity of strips from respective supply bobbins are interfolded and converged to form a booklet strand which is cut to length by a cutting station which reciprocates along the strand so that booklet lengths enter it and are cut. A rotating non-circular shaft passes through the cutting station and a sleeve in the cutting station slides axially along the shaft as the station reciprocates and rotates with the shaft. The sleeve is independently linked to a strand clamp and to a cutting knife which are separately timed and move along different paths, the strand clamp moving longitudinally towards and away from the strand while the knife makes a slicing movement across and through the strand. A fixed ejector driven by a second sleeve on the shaft ejects booklets from the cutting station into a discharge chute, the ejector being preferably driven by a pair of cams so that in its return stroke it passes above the strand advancing into the cutting station. With this arrangement the ejector can be as wide as the discharge chute and is not difficult to time.
