Abstract
1311191 Cooling extruded strands K MES. CHER F DIEDERIX E MURSCHEL [trading as C F SCHEER & CIE] 31 March 1970 [29 March 1969] 15310/70 Heading B5A [Also in Division B8] In the stretching and cooling of hot strands 12 of synthetic material, extruded from a die head 10, during passage through a cooling medium 16 between the nip of endless belts 32, 34, from which a further endless belt pair 70, 72 effects delivery to a rotary cutter 100, the belt 32 is normally spaced away from the belt 34 at the nip inlet where it passes over a roller 21, Fig. 2, but when a strand 12 breaks it follows a vertical path to interrupt a photo-cell 64 which actuates, through a control circuit, a double acting hydraulic motor 58 to displace the roller 21 and belt 32 to grip the broken strand against the belt 34, Fig, 1, and when the broken strand is engaged by the belts 32, 34 in the region of idler roll 22 the belt 32 is returned to its spaced apart Fig. 2 position, upon reverse actuation of the motor 58 after a variable time delay determined in the control circuit thereto. In Fig. 4, the full and dotted line position of piston 230 of motor 58 correspond respectively to the Fig. 1 and Fig. 2 positions of roller 21, to the latter whereof the piston 230 is displaced when an hydraulic valve spool 244, 245, 243 is displaced, against a return spring 246, in the direction 247 upon energizing of electromagnetic means 222. The apparatus is controlled from stop and start switches 204, 206, the latter 206 whereof energizes a main relay 200 which, via relay 200c and connector 208, effects commencement, optionally after a time delay, of the endless belt and cutter drives, and also opens a discharge relay 200e, and closes a charging relay 200d to charge a capacitor 213, over a period adjustable by potentiometer 210, until the gate voltage of a thryistor 220 reaches ignition point, whereupon current flows through relay contact 200f, limit switch 226, and electromagnetic means 222, to displace the piston 230 to the dotted line position, and through relay 218 to close contact 218a and discharge the capacitor 213 through the resistor 216. This movement of piston 230 opens, via piston rod cam 228, a by-pass connection around a contact 202a of a relay 202 which is controlled by the photoelectric means 64. If the beam between source 64
