    High technology, high quality, high output

    The automotive vehicle tyre is a high-perormance

    precision unit. The requirements o saety, com-

    ort, economy and environmental compatibility

    demand a high level o quality in every single tyre


    For the manuacturer, this means the application o

    technologies, which combine excellent quality with

    high output.

    KraussMaei Berstors response to this challenge

    is the delivery o complete high-tech extrusion lines

    or the production o tyre components.

    Our know-how matured over decades, our own

    patented developments and our active participationin the innovative processes o the tyre manuacturers

    all go to make us an expert partner or the industry.

    The demands and expectations o our customers

    are met with closely-targeted advice, highly-develo-

    ped project management methods, computer-aided

    component design and state-o-the-art manuactu-

    ring and application-specic commissioning.

    Our Technical Centres oer practical pre-contract

    support with production-scale machinery and labo-

    ratories with inspection and testing acilities. Trials

    are conducted under real conditions to secure the

    basis or each investment. The result is customer

    satisaction right rom the outset.

    Pre-assembly: precision in detail

    Pre-assembly defnes the level o the production

    technology. This is because pre-assembly of

    passenger car and truck tyres utilises al l the

    reserves o rationalisation, whilst simultaneously

    raisng the tyre component quality to a high level.

    KraussMaei Berstor machines are designed in

    concept to meet the special demands o the manu-

    acture o semi-fnished components. Duplex,

    Triplex and Quadroplex extrusion sets guarantee

    precise combination o the dierent components,

    totally ree o air inclusions. The end result is

    always more than the sum o the individual parts

    here is component technology in perection,

    allowing signicant rationalisation by reducing

    the number o working stages on the tyre buildingmachines.

    Quality and perormance

    without compromise

    All tyre makers are seeking ever-tighter manu-

    acturing tolerances, whilst throughput rates are

    steadily rising.

    KraussMaei Berstor extrusion lines are concei-

    ved or high product quality and maximum output

    and are equipped with extruders o dierent types

    (GE-SC or GE-KS) and sizes.

    The modular design makes or rapid recongura-

    tion to suit the mode o operation Mono, Duplex,

    Triplex or Quadroplex.

    KraussMaei Berstor Multiplex extrusion sets are

    designed in a piggy-back arrangement to achieve

    the highest product quality through symmetrical

    material fow in the head. In addition, the compact

    design makes or real space savings. A urther

    eature to satisy the quality requirements is the

    special design o the fow channels in the extrusion

    head. These ensure a very gentle, even material

    transer rom the round section at the extruder

    outlet to the rectangular fat orm o the prole. In

    addition, the changes in direction o the material

    fow in the fow channel are kept to a minimum.

    All stages o the process are controled by a monito-

    ring system, thus ensuring operational security.

    Throughput rates o up to 10,000 kg/h or about

    30,000 passenger car treads per day are achieved

    with these modern extrusion lines.
