... automatic transfer and shaping of the carcass Assemblies Carcass machine The carcass drum is interchangeable to adapt to different nominal core diameters. The carcass drum rotation is powered with a threephase current servomotor and is synchronized with the feeder belts for the inner liner-sidewall assembly, the ply and the shoulder strip to afford high tire uniformity. The carcass drum has a solid surface with full sleeve and a pneumatic radial stroke drive. Carcass ply servicer The carcass servicer has cartridge letoff stations for the innerliner-sidewall as--sembly and for two different bead rein-forcement pairs, steel cord ply and shoulder strip. The materials are aligned - in part electronically - via festoons and precision guiding devices. The stations for the innerliner-sidewall assembly, the plies and the shoulder strip have positively engaged conveyor belts with three-phase current servomotors and automatic length-cutting equipment. The bead reinforcers are fed onto the carcass via roller --con-veyors. The guide system can be changed quickly to accommodate steel or textile cord. Belt/shaping machine The belt/shaping machine has a coaxial shaft system for the belt drum and the shaping head. Four three-phase current servomotors power belt drum rotation and diameter adjustment and shaping head rotation and shaping head distance setting. The fine adjustment of the shaping head's central spindle shaft occurs during the carcass and belt assembly transfer operations to guarantee high tire uniformity. Belt ply servicer The belt ply servicer has cartridge letoff stations and automatic length-cutting devices for four different steel cord belt plies. Tires with five belt plies can also be manufactured if two belts are the same. The belts are aligned via festoons and precision guidance devices. The positively engaged drum feeder belts have three-phase current servomotors. Belt edge filler strip servicer The belt edge filler strip servicer are let off of a cartridge in pairs and mechanically fed onto the drum via roller conveyor belts. Tread servicer The tread is guided on the outer surfaces the whole time it is being applied. Transfer system The transfer system hangs down from above for good tool accessibility. The carrier consists of a large-volume hollow profile. The carcass and belt transfer systems are roller-guided and powered by a three-phase current servomotor, thereby ensuring high stiffness, maximum dynamics and the greatestpossible positioning accuracy. Three laser projectors are affixed above the carcass and belt drums. One is focused on the center light. The outer two operate in accordance with the formula for each tire component and material application dimension. A laser indicates the center of theshaping head. Stitching systems The carcass is stitched in crisscross fashion. The belts and the tread are each assigned a stitcher. The static stitcher stitches the tread and the sidewalls of the green tire with quickly changeable roller sets. Control The electric and pneumatically control unit complies with EN-directives. The machine sequences are controlled via a freely programmable Industry PC. Each of the two machine operators has a control monitor close to the cartridge drum and/or the belt drum. Functions, data, processes and error messages are visualized via flat panel display. Operation is menuguided via function keys. A third control monitor is available outside of the machine's work area for input and processing of formulas and machine parameters. The fusion of sensors and actors with controls is effected via a fast light bus. The unit's security system is realized via hardware circuits. The following operation modes are possible: - semiautomatic operation for production
- quality checks
- alignment and maintenance operation
Tools Tools can be supplied for tire dimensions 19.5" - 24.5". These consist of: - carcass drum
- belt drum
- belt drum segments**
- shaping head
