Longitudinal folder for printing material on rotary printing machine

摘要

The longitudinal folding device consists of a sharp funnel arrangement (5) that is orientated lengthways in the machine with the larger end being at the inlet (9). At the top edge of the component (12) the material is convexly bent, tangentially around a round component (13). In the operation of the printing panel (1) the support of the path bearing seat (15) of the former (4-4.4) is equal and extensive. The former has a control gear may be operated by either hand or electronic motor with the adjustable path of the material being optically, or electrically recorded and an average taken. The underside of the former may be parallel with the inlet of the funnel in the frame of the winding spool (21,22,23).
