METHOD OF REMOVAL OF A BEING DISASSEMBLED TOROIDAL SUPPORT FROM A VULCANIZED TIRE Russian patent published in 2005 - IPC

FIELD: tires production industry.

SUBSTANCE: the invention is pertaining to the tires production industry and may be used at in production of pneumatic tires. The method of removal of a being disassembled toroidal support includes stages of placement of the toroidal support carrying a vulcanized tire on the dismantling workstation. The toroidal support contains allot of sectors located along a circumference around of a geometrical supporting axis and attached to each other with the help of a flange and a counter flange being in a mutual interconnection on opposite to the axis direction concerning the sectors. The method provides for disconnection of the flange from the counter flange, displacement along direction of the axis of the flange and the counter flange at a space from the sectors and removal of each sector from the tire by a centripetal radial translational motion. At that at least to one of the sectors simultaneously with a centripetal radial translational motion impart an angular rotary relocation, which takes place around a pivot axis, that is essentially perpendicular to the direction being radial to the geometrical bearing axis and placed in a meridian plane shifted in a direction of the axis concerning an equatorial plane of the tire. The method ensures extraction of the sectors of the toroidal support from the vulcanized tire directly after removal of the tire from the installation without its deformation and elimination of the high strains formed in the space between sides of the tire.

EFFECT: the invention ensures extraction of the sectors of the toroidal support from the vulcanized tires directly after their removal from the installation and without deformation and a need to eliminate the high tensions formed in the space between the sides of the tires.
