[Class 120 (ii)] In a machine for winding string around wrapped bobbin electrodes for electrical batteries, the bobbin P gripped by driven automatically-operated tongs 7 is held at the other end by a spring-actuated positively driven plate 8 synchronizing with the tongs and holding the end of the string. Two parallel pairs of shafts 5, 6 are driven at the same speed from shaft 2 They may move axially while rotating. Pairs of bobbins taken from supports on a chain by forks 12 and members 21 which descend thereon are guided by a wall 14 to winding position, gripped by tongs 7 and plate 8, the string S held by tongs 15 being caught between the end of the bobbin and the plate. One layer of string is then wound, guide 16 operated by link 17 and slide 18, moving from plate 8 to tongs 7 and returning idly, Shears 20 then cut the string. |
