<p>366,546. Stapling artificial fibres. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Sept. 22, 1930, No. 28301. Convention date, Nov. 21, 1929. [Class 120 (iii).] Bundles of continuous artificial fibres are cut into lengths on a moving elastic base by knives rotating in the same direction as that of the movement of the fibres. A bundle a is guided over a rotating roller d, preferably rubber-covered, and is cut by knives c radially disposed on a cylinder b. The knives c, Fig. 2, may be tangentially disposed on the surface of the rotating support, and the roller d may be replaced by a travelling elastic band d, Fig. 2, a roller g pressing the bundle against the band. With this construction a bevel cut is obtained, the length of the fibres and the angle of the bevel being dependent on the radius of the circle of knives, and on the relative velocity between the knives and the fibres.</p> |
