Abstract
514,045. Spinning; seamed joints. DOVE, J. A. April 25, 1938, Nos. 9250 and 9252. [Class 83 (iv)] In shaping a seamed or seamless container 13 with or without an end 13a by means of pressure rollers 34 which bulge out the wall when rotated and/or reciprocated in the container as in Specifications 486,002 and 486,083, the surrounding shaped die 10 is in hinged halves, to allow the work to be inserted or removed at right angles to the work axis. The halves are held together by a latch 27 closed over their joints when the end support 16 is moved up axially by means of a cam slot 20 when the support is rotated by handle 21. The surrounding shaping die halves may be divided into transverse sections 22, Fig. 8, spring loaded at 23 to allow for limited axial expansion or contraction. The end support may have a similarly sprung end 16, Fig. 8, faced by a rubber &c. disc 28. To prevent seamed containers bursting the direction of the seam is reversed at the open end as at 37, Fig. 5. A flange 15a on the outer end-support 15 prevents inwards collapse of the seam during shaping.
