THERMOPLASTIC EXTRUSION AND RIBLINE APPLICATION
The Borum® Master 3000 series provides you with a variety of high capacity line marking machines designed for large scale jobs such as marking highways, motorways or airport runways.
The material tank capacity can be up to 445L. The possibility for the large material capacity naturally gives fewer stops during the day for refilling.
The BM 3000 has a two-seat slidable drive and operator section for flexible working on left or right side.
The thermoplastic Borum Dot’n line extruder can apply single and double lines of 5 – 50 cm width depending on the set-up. The extruder may be used for the application of flat lines, profiled lines, dots and a combination of dots and lines.
The Rib line equipment comes with fixed line widths up to 30 cm.
Line types that can be applied with this equipment
Non-pressurized thermoplastic tank indirectly heated via heat transfer oil. The thermal oil and thermoplastic material temperature is thermostatically controlled and regulated automatically.
Diesel burner system for heating of the thermal oil (and thermoplastic). Propane burner available on demand.
Vertical agitator (mixer)
With hydraulic transmission. Heated center pipe for efficient uniform temperature control. Perfect melting & homogenization of the thermoplastic. Stable construction with foundation and bearings at the top of the material tank.
The RibLine equipment is mounted directly on the side of the material tank. Alternatively, if the machine is also equipped with a thermoplastic extruder, you can mount it on the side of the extruder.
The equipment is supplied by an automatic filling system with a pneumatic level center.
The Dot’n line system offers a three-in-one solution for thermoplastic markings. This equipment can apply flat lines, dots and unique combination of lines and dots using only one extruder head.
In the drawing you can see examples of different valve set-ups giving different widths. The equipment's width can be between 30-50 cm. The line width starts at 5 cm and can be built up to 50 cm with 5 cm standard valves.
By using two sets of shutters the base line time to cure slightly before the Dots are applied and consequently the Dots will settle on top of the line with sharp edges, securing the optimum retroreflection.
Diameter of dots can be chosen between ø18 and ø 45 mm depending on the chosen drum. Number of dots/meter is 15-35 dots and is controlled by the LineMaster.
The shutters do not touch the high tensile steel drum and therefore the lifetime is prolonged.
Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven.
Continuous circulation of the thermoplastic material inside the equipment. This avoids settling and catching of solid parts and prevents unnecessary wear of mechanical parts.
The application speed depends on the type of application and goes up to 6 km/h.
The transport of material from tank to Dot'n'Line head is done by a hydraulically driven screw pump, which is electronically controlled. The screw pump has a permanent thermoplastic re-circulation system, which ensures a constant flow also past the in-active extrusion valves, keeping solid parts from adhering and ready for opening.
Build-in pressure regulating system ensures that line width and thickness do not change no matter the number of the shutters involved in the current marking assignment.
Having numerous dots gives the light a lot of possible areas to fall onto and create a retro-reflective effect. This is essential for having clear visibility, especially while driving during night time.
The drainage effect of the profiled markings ensures that rain water will easily drain away from the lines, thus maintaining high reflective values in rainy weather. This is possible because of the structure that allows the water to drain. Furthermore, the profiled nature of the road marking produces a noise when driven over that will warn the driver against driving off the road.
The Borum LineMaster allows you efficient control of all line marking tasks, from line application and pre-marking to reporting and invoicing. It is possible to store up to 99 different line types, and to arrange these in up to 30 different marking programs. You are also able to pre-set line widths, line types, colours and combinations to have them ready for marking, and can instantly adjust them on the go.
Pneumatically controlled quick cleaning system for removal of solids left in the extrusion slot. Can be activated while extrusion is in process and is only slightly detectable on the line in the form of a moderate thickening of layer.
