FIELD: machine building.SUBSTANCE: pick-up comprises shaft (2) with dual spring pins (4, 5) secured in pairs to its supports (3). Said pins comprise fastening, spring and working sections are fastened by single fastening element (6). Springs of pins are fitted one inside the other. Spacing between extreme outer spring turns of pins (5) with smaller spring diameter is larger than that of pins (4) with larger spring diameter. Transition from spring section of working section of pins with smaller spring diameter is flexed to align planes of revolution of working section of both types of pins.EFFECT: simplified design, smaller drum diameter.2 dwg |
