THE BIAS TYRE MANUFACTURING PROCESS:-

The pneumatic tyre is a composite structure madeout of rubber compounds, textile and wire materials. It has basic components, viz. Tread andSidewall (made out of rubber compounds) and Carcass (made out of rubber compounds, textileand wire materials). The Carcass has components Plies, Bead, Chafer, Flipper etc. The

process of tyre manufacturing involves mixing of various rubber compounds, dipping of fabric,preparation of various components, assembling the components to form the green tyre andcuring the Green tyre to the final shape. The entire production system has been broadly dividedin to 3 sections, viz. Div. A, Div. B, Div. C. The various steps of manufacturing are describedbelow.

PROCESSES UNDER DIV. A:-

MIXING:-All polymers are mixed with filler, process oil and other chemicals to give different grades ofrubber compounds in the 4 Banbury Mixers. 2 Banbury mixers are meant for mixing the MasterBatches. The other 2 are for mixing the Final Batches. In the Master Batch, the rubber is mixedwith carbon, process oil and other chemicals. In the final batch, the master batch rubber isagain mixed with sulphur and other vulcanizing compounds to enhance its cross-linkingproperty at the time of curing. 205 final batches are prepared in one eight-hour shift. I masterbatch corresponds to 1.52 final batches. Hence, only 134 master batches needed to beprepared in 1 eight-hour shift. 1 ready to use batch will be obtained after mixing 2.52 batches (1master batch and 1.52 final batches). 2 minutes are taken for mixing one batch. Therefore, 5minutes are taken for obtaining 1 ready-to-use batch weighing 80 kg. Approx. 2 truck tyres canbe made out of this 1 batch (1 truck tyre weighs 57kg, 85% of which form the rubber

compounds). The mixed batch is the dropped on a batch-off mill to make it in to sheet form.Each type of rubber compound is specifically compounded for tyre performance. The differentchemicals to be mixed are given particular codes. Detailed process specificationsencompassing the temperature and pressure to be maintained, quantities and codes of differentchemicals to be mixed , speed of mixing(60 rpm for master batch and 40 rpm for final batch) etcare available with the operators. After forming in to sheets a small piece of rubber compound iscut off from each batch and taken to lab for examining whether different chemicals have beendistributed uniformly. Only after getting the approval, it is sent to extruders, calendaring unit etc.FABRIC DIPPING:-The Nylon fabric is treated with latex, resorcinol, formaldehyde etc. , heated, stretched andcooled to increase its adhesiveness with the rubber compounds. It operates continuously for allthe 3 shifts.13000 metres are dipped in an eight-hour shift. Nearly 18 m. is required for 1 trucktyre. The line speed for the dipping unit is 30 yards/minute for the truck tyre. Different nylon

cords are required for the manufacture of different tyre types. Each type of nylon fabric requiresto be coated with a specific amount of latex. After dipping, the fabric is wrapped and packed in

polyethylene in order to prevent the absorption of moisture from the atmosphere and stacked inthe near by storage area.CALENDARING:-The dipped fabric is then fed in to 4-roll calendar to apply rubber compounds on both sides. Theadvantage of using 4-roll calendar is that both the sides of the fabric can be coatedsimultaneously and that too with different rubber compounds. The agreed output with the trade

union in an 8-hour shift is 55 rolls (23800 metres). The calendared fabric is then wound incotton liners to prevent sticking. The line speed is 60 yards/minute for truck tyres.DUAL EXTRUDER:-Components like sidewalls, treads are prepared using extrusion technique. The dual extruderconsists of 2 separate set of mills on which 2 different types of compounds are broken down,heated and fed to 2 different screws. The 2 compounds are then extruded together in acommon head. With the help of a performer and final dies, these emerge in to predeterminedshape. The advantage of using dual extruder is that rubber compounds of completely differentcompositions can be extruded. It takes 15-20 minutes for the rubber compounds to be formedinto a tread. The line speed for the truck tyre is 40 feet per minute. The output is 5 truck treadsper minute. In the case of sidewalls, the output is 1500 sidewalls in eight hours. The dualextruder is considered as the bottleneck in Div. A. 1 tread and pair of sidewalls is required for 1truck tyre. The output for dual extruder is 1920 equivalents. Each type of tyre is assigned a

factor. The no. of treads prepared (which corresponds to no. of tyres) multiplied by the factorgives the output in equivalents. The sum of the output of the different tyres will be equal to1920 equivalents in eight hours. The line speed is 38 FPM for treads and 16FPM for sidewalls.SQUEEGE APPLICATION:-The calendared fabric is further applied with a layer of rubber compounds using 3-roll calendar.The output is 192 rolls per eight hours. The fabric required for 6 tyres can be obtained from 1roll. 3 such machines are there.PREPARATION OF CHAFERS, BREAKERS AND FLIPPERS:-The rubber compounds required for the above components, mixed in the Banbury is fed to thecorresponding machines. 6150 breakers are obtained in an 8-hour shift. 152 rolls of chafers andflippers each are obtained in eight hours. The components required for 18 tyres are obtainedper roll.PROCESSES UNDER DIVISION B:-

BIAS CUTTING:-Bias cutters are used for cutting calendared fabrics to specified widths and angles known asplies. Eight plies are required for 1 truck tyre. The width depends upon the type of tyre and theangle of the cut depends on the type of tyre services required. 25 seconds are required to cuteight plies. 6 bias cutters are there. Therefore, plies for 6 tyres are obtained in 25 seconds.From a roll of 430 metres, we will get ply required for 40 truck tyres.BEAD WINDING, FLIPPING AND APEXING:-The function of beads in a tyre is to anchor it while mounting the rim of vehicles. The bead wireis coated with rubber compound in a T-head extruder and wound in to coils of requireddimension. The coiled beads are further applied with rubber and calendared fabrics ofappropriate dimensions. 4 beads are required for a tyre. 5100 beads are prepared in 8 hours in4 machines.

TYRE BUILDING:-Tyre Building Machine (TBM) has a turret for holding a no. of plies, breakers, chafer rollsbesides tread applying conveyor. According to the size of the tyre to be built, specified buildingdrum is mounted on the shaft (which can rotated at different speeds and in both directions) ofTBM. The fabric layers and bead wires are applied to the drum, which are compressedtogether. After building the cord carcass on the drum, the tread, sidewalls and chafers areapplied. The Green Tyres thus formed are removed from the drum by collapsing the same.PROCESSES UNDER DIV. C:-

TYRE CURING:-The Green Tyre is prepared for vulcanization by the application of lubricants on the inner and

outer surfaces for better moulding, awling (the sidewalls are pierced with the needles to releasethe trapped air) and punching. The Bagomatic Curing Press consists of a thin synthetic cured


5/17

bladder positioned in the centre of the bottom half of the mould over which the green tyres areplaced. The steam pressure is applied in to the bladder and it is increased till the green tyretakes the complete shape of the mould when the press is closed. Curing media like hot water,steam etc are passed through the bladder while the outer surface of the mould is heated by thesteam. The internal pressure is critical for the purpose of obtaining good moulding effects. Theheat to be applied to the different locations of tyre compounds has to be as per specifications.

Less temperature will result in under cure condition and more temperature will result indeterioration of rubber compounds. Afterwards, the tyre is taken out, mounted on a speciallydesigned rim and inflated to required pressure, while it is still hot. This is to prevent the loss ofshape when it is suddenly brought to room temperature after relieving the pressure. The tyre iscooled under inflation (for almost double the time taken for curing). This is known as Post CureInflation (PCI). The truck tyre takes 43 minutes for curing and 80 minutes for PCI. The no. ofPCI presses are double the no. of curing presses. 48 cavities are there for truck tyres. 10 tyresare cured per cavity in eight hours. The achieved capacity is 92 metric tons per shift whichconsists of other tyres also.INSPECTION AND WAREHOUSING:-The cured tyre is then trimmed off flashes, inspected and warehoused.
