Filed: 1971-04-19
Abstract: 1316001 Quading apparatus OKI DENSEN KK 19 April 1971 [7 April 1970] 24742/71 Heading DIT Four elements 1, 2, 3, (4) that are to be twisted together are drawn from a single supply roll 33 on a reel 15. The elements 1, 2, 3, (4) then pass over a paying out flyer 13 and through apertures 8 in a brake flyer 7 before meeting at a guide 6 where they are twisted together to form a quad 5. The flyer 7, flyer 13 and reel 15 are mounted on individual co-axial shafts 30, 31, 32. As the quad 5 is drawn off at constant speed the elements 1, 2, 3, (4) rotate at an ever increasing rate about the axis of the reel 15. When this direction is in the same direction as the rotation of the reel 15 the ratio between the sheaves 20 and 21 and between the sheaves 23 and 22 is such that the paying out flyer 13 rotates in the same direction as the elements 1 to 4 and at a higher speed than the maximum speed that will be achieved by said elements relative to the reel 15. The flyer 13 thus rotates at a speed higher than that of the reel 15. When the elements 1 to 4 rotate in the opposite direction to that in which the reel 15 is to be driven, the speed of the flyer 13 is maintained at a lower value than that of the reel 15. Flyer 7 acts as a brake and can be braked by a torque motor 29; or an electromagnetic brake; or a mechanical brake.
