The invention discloses a method for increasing recovery rates of lead and zinc during lead-zinc sulfide ore dressing-smelting joint application. The method is implemented by the following steps of: performing floatation on lead-zinc sulfide ore to obtain lead concentrate, adding an appropriate amount of inhibitor in the flotation process to inhibit zinc and adding a collector and a foaming agent; and after floatation, selectively leaching zinc metal out of the lead concentrate by pressure acid leaching, performing liquid and solid separation on leached ore pulp and introducing metal zinc into solution so as to obtain lead-enriched slag. The floatation of zinc is restrained intentionally in the floatation process of the lead-zinc sulfide ore, so that the recovery rate of the lead concentrate is increased and the recovery rate of lead metal is over 90 percent; and the metal zinc is selectively leached out of the lead concentrate by pressure acid leaching and lead sulfide is insoluble in dilute sulphuric acid but leaves in a slag phase, so that the zinc leaching rate is over 98 percent in the pressure acid leaching process of the lead concentrate.

A method for cutting a laminated film, adapted to cut the laminated film using a circular cutter having a cutting edge at the peripheral edge thereof. The method cuts the laminated film by rotating the circular cutter by a rotating means in the forward rotational direction relative to the cutting direction at a cutting-edge peripheral speed Vr while causing the laminated film to travel in the cutting direction at a travel speed Vc. The relative cutting speed V obtained by subtracting the peripheral speed Vr from the travel speed Vc is set in the range from minus 50 m/min to 30 m/min inclusive.
