Abstract

661,851. Making tubes. ROBINSON, E. B. July 11, 1947 [March 20, 1946], No. 8654/46. Addition to 653,613. Class 40 (iii). [Also in Groups VIII and XXVIII] In a machine for making tubes by helically winding strip material 2, 3 on a stationary mandrel 4 the tube is cut simultaneously into a number of small lengths by a plurality of cutters 7. A rod 6 in the hollow mandrel 4 carries a slidable mandrel extension 6a having grooves 9 which register with the cutters, the rod and cutters being commonly reciprocated in one direction at the speed of the formed tube and with a quick-return motion. The cutters are moved laterally by a ramp 10. The cutters are controlled in accordance with the position of designs, printing, &c. on the tube or strip such as by light-sensitive means or by other devices described in the parent Specification.
