DOFFING DEVICE FOR REMOVAL OF WOVEN CANVAS AUTO TIRES FROM AN ASSEMBLY DRUM Russian patent published in 2004 - IPC

FIELD: production of pneumatic woven-canvas auto tires. SUBSTANCE: the invention presents a doffing device, that may be used for removal of woven-canvas auto tires from then assembly drums, in particular in the builders for removal of gathered pneumatic woven-canvas auto tires from an the assembly drums. The doffing device has a carriage mounted on a rail way and capable to move in the axial direction from the drive. The carriage contains mounted on their levers some roller-type pickups and drives of their motion made in the form of the pneumatic cylinders. The rollers are installed on the pantograph systems mounted in the post of the carriage and linked with a two-way pneumatic cylinder. The pneumatic cylinder is fixed with the help of a cantilever on the post of the carriage. On the post over the pantograph systems there is a pusher made in the form of a ring-type member with a spanning angle of no less than 200 dg. The ring-type arresters are installed on the rollers with an opportunity of linear motion. The invention has a simple design, eliminates deformation of the pneumatic woven-canvas auto tires at their doffing and ensures high quality of manufactured pneumatic woven-canvas auto tires. EFFECT: a simple design, elimination of deformation of the pneumatic woven-canvas auto tires at their doffing , high quality of production. 2 cl, 8 dwg
