PCT No. PCT/SE91/00366 Sec. 371 Date Nov. 23, 1992 Sec. 102(e) Date Nov. 23, 1992 PCT Filed May 21, 1991 PCT Pub. No. WO91/17855 PCT Pub. Date Nov. 28, 1991.An apparatus for cutting a cylindrical sleeve (7) during continuous displacement of the sleeve (7) in its longitudinal direction, for example in connection with continuous manufacture of the sleeve (7) in an appropriate machine. The apparatus includes a longitudinal slide (30) which is displaceable synchronously with the sleeve (7) during rotation thereof and movement in its longitudinal direction. A knife (36) is impressible into the wall of the sleeve (7) during longitudinal displacement of the slide (30) and the sleeve (7). The knife (36) is mounted on a cross slide (39,40; 43,44) which is reciprocal transversely of the longitudinal axis of the sleeve (7), and thereby transversely of the direction of movement of the longitudinal slide (30) for impressing the knife (36) into the wall of the sleeve (7) for cutting a desired length of the sleeve. |
