Jointed shaft rotate and draw in；During drawing in, the edge portions of carcass assembly is pressed against on capsule 8 by finger-type sheet.
Now, finger-type sheet 4 draws in, is clipped between finger-type sheet 4 and capsule 8 by the edge portions of carcass assembly, and along with finger-type
The gathering of sheet 4 is constantly pressed towards the axle center of forming machine main spindle O.
4, the buckle ring step in described step 3 includes:
Triangular glue steel-wire ring is arranged on the end of the jaw 7 of buckle ring driving means 6；Buckle ring driving means 6 promotes jaw 7,
Triangular glue steel-wire ring is pushed to the setting position of carcass assembly by jaw 7；Afterwards, jaw 7 is in the driving of buckle ring driving means 6
Under, return to home position, complete buckle ring action.
After the above step, outer sleeve device A and finger-type sheet devices B direction away from carcass drum simultaneously move one section away from
From.
5, the retainer step in described step 4 includes:
Piston 28 moves towards carcass drum, and then promote sliding plate 11 axially move closer to carcass drum 2 so that on push rod 10
Rising, capsule 8 is connected on carcass assembly by the lock dog 9 at push rod 10 top closely.
6, the anti-package step in described step 5 includes:
Spreading inflated by capsule 8, upwards and towards carcass drum extrudes carcass assembly, and meanwhile, boosting dish 5 is by the capsule of protuberance
8 push carcass drum to, are overlying on outside triangular glue steel-wire ring by carcass assembly reserved packet, complete turn-up process.
First anti-package device is in the anti-package device K on the first carcass transfer device of carcass drum side, and the second anti-package device is
Being positioned at the anti-package device K ' of carcass drum opposite side, it is identical with working method with the structure of described anti-package device K.
