Abstract (en)
[origin: EP0408964A1] Screw press having a screw barrel (1) with feed opening (2) for comminuted old paper or the like, in which a taper-bore mounted pressing screw (5) rotates, having an outlet opening (3) for extruded mouldings (4), which opening is followed by a gripping press (6) for holding back the mouldings, and having an injection device (10) for water, in which a displacement-recording sensor (17) senses the discharging movement of the extruded moulding (4) and activates a first electric switching device (13), which opens a control valve (18) for the injection device (10) and closes it with a time delay which can be set, at the same time activates a second electric switching device (15) for delayed switching of the power supply of the drive motor (8) of the screw press, which motor switches off with a time delay when the extruded moulding (4) is at a standstill, and in turn activates a third electric switching device (16), which switches the reverse running or forward running of the drive motor (8) with a delay. <IMAGE>
