DOT'N LINE THERMOPLASTIC EXTRUSION AND COLD PAINT APPLICATION
The BM 5000 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 BM 5000 DL C is a combination machine that can be used for applying both thermoplastic and cold paint markings in various widths.The cold paint material tank capacity is 440 L and the cold plastic material tank is 585 L. The possibility of large material capacity naturally gives fewer stops during the day for refilling.The BM 5000 has a two-seat slidable drive and operator section for flexible working on the left or right side.
Line types that can be applied with this equipment
Pressurized black steel tank for solvent - based cold paint.
The material tank has a filling system with large filling holes. This makes the filling process very easy to manage. In addition, the large filling holes also make cleaning the tanks easy.
Driven by hydraulic motor and with manually operated reversing valve.
Non-pressurized thermoplastic tank, indirectly heated via heat transfer oil. The thermal oil and thermoplastic material temperature is thermostatically controlled and regulated automatically according to the settings
Diesel burner system for heating of the thermal oil (and thermoplastic). Propane burner is 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.
Air spray with atomizing air is a method of marking that uses a pressure tank for the material and compressed air to atomize and spray the paint onto the road surface.
For all Borum spray machines, the equipment is mounted on a sliding retainer frame as standard that allows you to quickly slide the equipment from one side to another. You can have 1-3 paint guns, depending on the set-up of the machine, and 1-3 bead guns are attached.
The ground distance is maintained by a retainer wheel to ensure a constant road marking width. Lifting of retainer is pneumatic and done from the operator's seat.
Paint filter with cut-off valve for easy maintenance.
The machine can be equipped with two material tanks so that dual-color marking can be carried out simultaneously.
Working speed can be up to 15 km/h depending on the conditions, e.g. material, line type, and operator experience.
High-performance spray gun. with a 6 mm nozzle set for water-based, solvent-based and high solid paints. The BM C 6 gun can work with paint marking pressure up to approx. 8 bar.
Air capacity of 300-700 L/min. is needed per gun.
Possibility to apply lines in widths from 8 to 20 cm with one gun depending on work conditions, nozzle size, application speed, and layer thickness. Line thickness is typically between 0.25 mm to 0.80 mm.
Cold paint material is a cost-effective solution for executing flat markings over all types of pavements and for use in repairments. Flat lines are mainly used in well-illuminated areas as urban roads for e.g. where the lines do not need high retroreflectivity levels.
Although drying time different between types of paints, it is usually quite long and cones and traffic management might be needed.
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 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 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.
10L pressure solvent tank for cleaning of hoses and paint guns.
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.
