Abstract
A ply station 12, a band station 13, a shaping station 14, and a belt-tread station 15 are disposed along one side of a conveyor line 11 which extends linearly. A first feeding apparatus 16 disposed between the stations 12, 13, a second feeding apparatus 17 between the stations 13, 14, and a third feeding apparatus 18 between the stations 15, 14 are movably supported on the conveyor line 11. A vulcanizing station 19 comprising a plurality of vulcanizers 20 is disposed on a second side of the conveyor line 11. A delivery apparatus 22 is disposed between the vulcanizing station 19 and the shaping station 14.
Claims34
A system for producing a tire by individually manufacturing an inner lining element (51) and an outer lining element (70) and putting the outer lining element (70) on an outer circumference of the inner lining element (51) to form a green tire (80), comprising:
- a first apparatus group (101) for manufacturing said inner lining element (51) using a first ribbon (41) of rubberized cord fabric;
- a second apparatus group (102) for manufacturing said outer lining element (70) using a second ribbon (58) of rubberized cord fabric;
- a third apparatus group (103) for forming the green tire (80) by putting said outer lining element (70) on said inner lining element (51);
- and
- a fourth apparatus group (104) including at least one vulcanizer (20) for cross-linking the green tire (80) into a completed tire (87).
A method of producing a tire, comprising:
- a first step of winding a first ribbon (41) composed of filamentary cords (25) coated with rubber (36) around drums (42), thereafter cutting off a ribbon cylinder into body ply materials (46A, 46B), and winding or fitting the body ply materials (46A, 46B), a band (35), and beads (48A, 48B) around a band forming drum (28) to form an inner lining element (51);
- a second step, concurrent with the first step, of winding a second ribbon (58) composed of filamentary cord (251) coated with rubber (361) around drums (52, 53), thereafter helically cutting off a ribbon cylinder into belt materials (62a, 62b), and winding the belt materials (62a, 62b) and treads (67, 69) around an outer lining element forming drum (54) to form an outer lining element (70);
- a third step of inserting said inner lining element (51) into a drum (75), inflating the inner lining element (51), putting said outer lining element (70) on the inner lining element (51) to form a green tire (80) which substantially has a final tire shape;
- and
- a fourth step of vulcanizing the green tire (80) formed in the third step.
