VEE SEVEN believes in the boundless advancementof retread technology. In the past thirty years we haverevolutionized the concept of retreading by delivering TyreRetreading machinery of top notch quality. We have alwaysbelieved in adding value to our customers by providingmachinery that reduce manpower, increase production andenable continuous operation. A testament to this fact is therepeat purchases from our customers year after year.

We engage in positive customer feedback andchange continually to incorporate new technologies into ourproducts. It is proudly announced that we are the firstmanufacturer of Pre-cured machinery in Kerala. Vee Seven'sbiggest strength is its satisfied Customers across the IndianSubcontinent, South East Asia, Middle East and Africa.Manufacturers of: Pre-cured & Mould Cured Tyre RetreadingMachinery and all accessories, Exporters & ApprovedSuppliers of Government institutions.

Retreading is the process whereby selectedand inspected worn tyres, called "casings,”receive a new tread. Only sound, carefullyinspected tyre casings are used forretreading. The worn tread is buffed awayand a new tread bonded to the tyre body ina process very similar to the manufactureof a new tyre. There are differentprocessing techniques, but the ultimateobjective is always the same - affixing anew tread through the application of heat,time and pressure.There are mainly two methods forretreading. They are Pre-cured Method andMould Cured Method. In Pre- CuredRetreading Cured Tread Rubber is affixedon to the casing. In Mould Cured methodUncured Rubber is used. Moulds are usedto transfer the design elements on the tyreto the uncured tread. Retreading is anenvironmental friendly method whichreduces our dependence on fossil fuels.

Tyre Retreading Over View:

Vee Seven Pre-cured Electric Chamber

Electric Chamber is an autoclave powered by electricity used for Curing of Pre-cured Tyres. The Casing is bonded with the Pre-cured Tread under the application of Pressure and Temperature for a fixed period of time inside the Electric Chamber. The Lock Ring Closure is mechanism that ensures safety by creating a pressure tight container once curing is started. The lock ring is controlled by pneumatic double pistons which ease the process of door opening and closing. This ensures minimal time between subsequent loading and unloading of tyres into the chamber which in turns ensures higher efficiency. Vee Seven Electric Chambers are very much appreciated for its Robustness and Trouble Free Service.

• Sturdy Construction

• Best in Class Switch Gear and Pneumatic components

• Extra level of electrical protection and to ensure worker safety

We can provide customised solutions in capacity of Electric Chambers in terms of your daily demand of tyres. In case of a smaller plant with cost constraints we offer you electric chamber with manual locking system. A Tyre lifter is also provided for loading and unloading of tyres in to the chamber.

Vee Seven Pre- Cured Buffer

Pre-Cured Buffer is used to remove worn out tread from Casing. Vee Seven Pre- Cured buffer makes that process effortless. Tyres are loaded on to the expandable hub which can adjust to a wide range of tyre sizes saving a lot of time during tyre size changes. The buffing is smooth due to its high end buffing motors and feather touch controls. A wide array of indication lights are provided so that operator is always informed about the operation. The cyclone filter provided along with the buffer collects the dust particles created during buffing. The movable bed is also motor powered which further eases the process.

Vee Seven Pre- Cured Tread Builder

Builder enables the new tread to be fixed on the casing before the curing operation. Vee Seven Pre- Cure Builder is provided with a expandable hub for loading of casing. The Rotation is controlled by foot pedal switch. The Pressure is applied on the tread and casing by aluminium rollers which are controlled by a pneumatic piston. There is a main roller and two support rollers to ensure uniform application of pressure on the tread. A pneumatic cutter is also part of the machine for splicing the tread at the appropriate length.

Vee Seven Envelope Expander

Envelopes are tight fitting sleeves inside which the built tyre casing is kept during the curing operation. The envelopes ensure uniform application of pressure on the tread during the curing operation. The loading of built casing into tight fitting envelopes is a physically demanding job manually. Hence envelope expanders are used to ease the task. The envelope is loaded on the table and is stretched by the pneumatic claws. The Built casing is loaded above it by the lifting arrangement. The Casing is centred and lowered on to the stretched envelope. The jaws are released to allow the envelope return to its normal shape. The enveloped casing is then loaded into the curing Chamber.

Vee Seven Inspection Spreader

Tyres before starting the process of retreading have to be inspected to decide whether they are fit to be retreaded or not. Also the irregularities in the casing can be indentified by the trained eye during this procedure. The Inspection spreader has a tyre loader pneumatically powered to load the tyre on to the inspection base. The Two claws stretch the two walls of the casing improving the visibility on the inside surface of the casing. The casing can be easily rotated with the help of aluminium rollers provided. The inspector decides whether to discard the tyre or forward the tyre for repairs and retreading after inspection.
