THERMOPLASTIC SPRAY AND DOT'N LINE EXTRUSION APPLICATION
The BM 5700 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.
Line types that can be applied with this equipment
Pressurized tank indirectly heated via thermal oil. The thermal oil and thermoplastic material temperature is thermostatically controlled and regulated automatically.Burner systemDiesel 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 and homogenization of the thermoplastic. Stable construction with foundation and bearings at the top of the material tank.Advantages when using a pressurized tank for spray:The line thickness is affected by the machine speed, this is useful for applying thicker lines in curves and areas with higher wear and tear levels.The maintenance for the pressure tank is minimal compared to the thermoplastic spray pump system.
Sliding retainer frame, upon which 1-3 spray guns and 1-3 bead guns can be attached. Easy slidable from side to side for an optimal working position. Ground distance is maintained by retainer wheels hereby ensuring a constant road marking width.Lifting of retainer from operators seat is done using a hydraulic cylinder.All material pipes are oil-jacketed and insulated to maintain an ideal material temperature.Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven.Line thickness is typically between 0.75 mm to 1.5 mm.Marking speed up to 15 km/h depending on the work conditions, operator, etc.
Automatic high-capacity spray plastic gun. Consists of an oil jacketed gun body and a pneumatic cylinder. Possibility to apply line widths ranging from 10 - 20 cm depending on line thickness, work conditions, application speed and layer thickness. As an alternative, we offer a narrow nozzle, which can spray 5-15 cm with one gun. Optional narrow nozzle size of 3 mm or wide nozzle size of 7 mm.The guns are mounted on a sliding retainer frame, on which 1-3 spray guns and 1-3 bead guns are attached. Easily slidable from side to side for an optimal working position. Ground distance is maintained by retainer wheels to ensure a constant road marking width. All material pipes are oil-jacketed and insulated to maintain an ideal material temperature. Lifting of retainer from operators seat using a hydraulic cylinder.
Due to the equipment working via a pressure vessel, it is very simple and easy to use as the pressure in the vessel is the same as the pressure in the application. Furthermore, the tank requires very little maintenance.Thermoplastic spray markings are a cost-efficient solution as the applied lines do not require as much material as extruded profiled markings. Furthermore, this type of material forms a uniform application that is more durable and dries faster compared to cold paint applications.
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 total line width can be between 30-50 cm depending on the set-up. The line width starts at 5 cm and can be built up to 50 cm with 5 cm standard shutters.
By using two sets of shutters the base line has time to cure slightly before the Dots are applied. Consequently, the Dots will settle on top of the line with sharp edges, securing the optimum retroreflection.The diameter of dots can be chosen between ø18 and ø 45 mm depending on the chosen drum. The number of dots/meter is 15-35 dots and is controlled by the LineMaster.The shutters have no contact with the high tensile steel drum and therefore wear is minimalized and lifetime is prolonged.Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven.Pneumatically controlled quick cleaning systemfor removal of solids left in the extrusion slot.It can be activated while extrusion is in processand is only slightly detectable on the line in theform of a moderate thickening of the layer.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 auger screw pump, which is electronically controlled. The screw pump has a permanent thermoplastic re-circulation system, which ensures a constant flow also past the inactive extrusion shutters, keeping solid parts from settling and keeping the equipment ready for working.Build-in pressure regulating system ensures that line width and thickness do not change no matter the number of shutters involved in the current marking assignment.
Having numerous dots in a line 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 control unit is an easy way of setting and controlling your line marking jobs. The LineMaster is attached to the operator's section of the machine and gives you full control of all your 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 and different combinations to have them ready for marking, and can instantly adjust them on the go.Furthermore, you are able to view the status of various parts of the machine (e.g. compressor) on the computer screen that will help with correctly maintaining the machine and avoiding break downs.
Pneumatically controlled quick cleaning system for removal of solids left in the extrusion slot. It 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.
