KraussMaffei Berstorff designs complete line concepts to attain perfect interplay of all components under changing parameters. Based on our wide experience, join together all elements of the production line...

Reject roller train Cross-cutting unit Manual pick-off roller train – cut-piece operation Wind-up stations Cutting units (Skiver) – lying cut or start/stop cut for cut-piece operation with the f highest cut quality, length precision and maximum cut rates per minute, rotary cutting for wind-up operation Cooling systems – units for spray or immersion cooling Spray cooling Cementing station – to increase adhesion of the splice surfaces Cut-piece operation – manual pick-up roller train – automatic booking system Wind-up operation – cassette winders – spool winders

Multiplex Lines Quality and performance without compromise Multiplex Lines Quality and performance without compromise All tyre makers are seeking ever-tighter manu­facturing t ­ olerances, whilst throughput rates are steadily rising. KraussMaffei Berstorff extrusion lines are conceived for high product quality and maximum output and are equipped with extruders of different types (GE-SC or GE-KS) and sizes. The modular design makes for rapid reconfiguration to suit the mode of o ­ peration – Mono, Duplex, Triplex, Q ­ uadroplex or Quintoplex. KraussMaffei Berstorff Multiplex e ­ xtrusion...

Pre-assembly of a Multiplex extrusion set

Multiplex Lines Multiplex extrusion heads and tools Multiplex extrusion heads and tools Versatile and efficient: systemised head operation The range of different tyres dictates the requirements for changing the compound, dimensions and programs run on any production line, whilst the extrusion head determines the quality and efficiency of the tyre production. Multiplex extrusion heads from KraussMaffei Berstorff represent the state of the art with – orking widths up to 850 mm for up to w 2 treads in one production pass – locking forces up to 10,000 kN – onnection of up to four extruders of c...

Multiplex Lines Control and automation Control and automation Multiplex Extrusion Lines Planning and construction of the electro-technical equipment for the extrusion lines are carried out in modular form to the latest standards. Customised configurations can be quickly created without problems. The extruder motors are equipped with microprocessor drives, digital actual value access and bus connector set point provision. This technology ensures a high degree of repeatability, exact regulation and dynamic screw speed control. All this has a direct influence on the quality of the extruded...

Multiplex Lines Multiplex Extrusion Lines Multiplex Extrusion Lines High technology, high quality, high output The automotive vehicle tyre is a high-performance precision unit. The requirements of safety, comfort, economy and environmental compatibility demand a high level of quality in every single tyre component. For the manufacturer, this means the application of technologies, which combine excellent quality with high output. KraussMaffei Berstorff’s response to this challenge is the delivery of complete high-tech extrusion lines for the production of tyre components. Our Technical...

Multiplex configurations Precision in detail Pre-assembly defines the level of the production technology. This is because pre-assembly of passenger car and truck tyres utilises all the reserves of rationalisation, whilst simultaneously raisng the tyre component quality to a high level. Extrusion Head KraussMaffei Berstorff machines are designed in concept to meet the special demands of the manu­ acture of semi-­ f finished components. Duplex, Triplex, Quadroplex and Quintoplex extrusion sets guarantee precise combination of the d ­ ifferent components, totally free of air inclusions. The...
