<p>1,000,696. Cutting webs. MOLINS ORGANISATION Ltd., and E. S. DOERMAN. Oct. 14, 1963 [Oct. 15, 1962], No. 38924/62. Heading B4B. [Also in Division A2] A rotatable cutting device comprises a cutting member having cutting edges, a rotatable drum 6 in which the cutting member is rigidly mounted, a counter surface against which the cutting member cuts, a shaft 5 about which the drum rotates and a diaphragm 7 connecting the drum 6 to the shaft 5, the diaphragm being capable of flexing so as to permit the drum to rotate about an axis transverse to that of the shaft whereby the cutting edge is aligned with the counter surface. The shaft 5 has a flange 8 and stepped portions 9, the side of the flange 8 adjacent the portion 9 being slightly relieved on its face 10. Spacing rings 11 and 12 fit over the portion 9 and hold the diaphragm 7, the assembly being secured by a locking sleeve 13. The face of the sleeve 13 adjacent the diaphragm 7 is also relieved at 10a. Further spacing rings 14 and 15 hold the periphery of the diaphragm, the rings being held together by abutment against a locking nut 17, secured to the drum 6 by screws 18, and an internal face 16 of the carrier 6 respectively. The diaphragm 7 allows flexing of the carrier 6 within the limits set by the relieved faces 10 and 10a. The shaft 5, which is capable of bending slightly, is mounted in eccentric bearings 24 and 25.</p> |
