1. a tire assembly drum, described tire assembly drum has turn-up mechanism, and described tire assembly drum carrys out shaping unvulcanized tire for using rubber tyre component (t) and two bead cores (b), and wherein, described tire assembly drum is provided with:

  • The basic element of character, the described basic element of character has central dram axle (1);

    Two ring segments (13), described ring segment (13) is arranged to around described central dram axle and is spaced from each other, for supporting described bead core (b);

    Extending apparatus, described extending apparatus radially stretches for making the part be placed in described ring segment of described rubber tyre component;

    Two groups of axially extended arms (14) when being in original position, described arm (14) is arranged in the either side in the outside of described ring segment, wherein, be oriented towards first of described ring segment the free outer end place, described arm is provided with the first anti-package element (11), and at the second relative outer end place, described arm is articulated with the arm support member (17) of axially-displaceable position;

    Shift unit, on the one hand, described shift unit is used for making described arm support member (17) be shifted to make described second outer end of two groups of arms (14) axially move toward each other in a first direction, wherein, described arm can tilt to obliquity from described original position in a radial plane, make the part being placed in the outside of described ring segment of described rubber tyre component be pressed against the expandable part be placed in described ring segment of described rubber tyre component for making described first free outer end axially and radially moving thus simultaneously, and on the other hand, described shift unit axially moves to described original position for making the displacement of described arm support member (17) in second direction opposite to the first direction to make described arm (14) leave described obliquity,Checkout gear, whether described checkout gear is in desired location at least one movable part detecting described tire assembly drum,It is characterized in that, the air duct (20) that described checkout gear comprises compressed air source (23) and is connected with described compressed air source or can be connected with described compressed air source, wherein, described air duct comprises outlet (k2), and, described movable part at least being in or close to being connected in described outlet during desired location, to regulate or the flowing that changes in described air duct and/or pressureWherein, described checkout gear also comprises the flowmeter (F) and/or pressure gauge (P) that are respectively used to measure flowing in described air duct and/or pressure.
