Abstract

A rim clearance adjusting device of a postcure tire inflator is capable of automatically adjusting a clearance between upper and lower rims, A vulcanized tire from a vulcanizer is filled with high-pressure air for inflating and cooling purposes. For these purposes there is installed a rotating screw member which holds the tire between the separable upper and lower rims, and moves the lower rim upwards and downwards between the lower rim and its support member. Also there is provided a sliding device for moving the lower rim, together with the support member thereof, between the lower position of the upper rim and the intermediate position on the vulcanizer side. And furthermore there is mounted a driving mechanism for driving the rotating screw member to the intermediate position.

Dependent claims

A postcure tire inflator including a rotating frame, a first set of separable first and second rims, the first rim being mounted to the rotating frame, means for filling high pressure air in the tire, and a rim clearance adjusting device comprising:

a first screw member mounting said second rim such that said second rim is moved vertically toward or away from said first rim upon rotation of said screw member;
a first sliding device supporting said second rim and said first screw member for reciprocating movement between a first position out of vertical alignment with said first rim and a second position spaced from said first position, said second position being located in vertical alignment with said first rim;
and
a driving mechanism positioned to engage said screw member so as to rotate said screw member and adjust a vertical clearance of said second rim when said second rim is in said first position.
