3 About us Since 1952 HOFMANN have been supplying roadmarking equipment and gained international recognition as a qualified partner in all aspects of roadmarking technology. The range of products encompasses everything the heart desires for roadmarking: From small, hand-controlled machines and self-propelled, ride-on machines to roadmarking trucks in various sizes up to 29 tonnes total admissible weight, drying and line remover machines, and also melting machineries of thermoplastic materials. Benefits are experienced in: MultiDotLine -/ MultiDot- Line Plus Extruder for defined agglomerate-, profiled and plain markings Spotflex -system for defined agglomerate, profiled and structure markings Metering pumps designed to operate path-dependently (CONEX ), thus maintaining the set volume of material per metre line length irrespective of any changes in travel speed (AMAKOS ) At the customer s request, Hofmann can liaise with them and devise individual application solutions at hand. Users take considerable advantage of HOFMANN s close contacts to both R&D as well as practical application. It has formed a tradition to meet at HOFMANN s TechnologyDay & International Expo - a forum to bring forward communication between participants in roadmarking: paint producers and ministerial authorities, road markers and scientific tutors. Various application systems are available for paints, sprayable and extrudable 2-component cold plastics, as well as for sprayable and extrudable thermoplastic materials.depending on the type of marking material, they are also available for low-pressure (atomising air method/airspray) or Airless high-pressure marking. Expert advice and guidance for our customers from the point of purchase to commissioning as well as training by our engineers go without saying. Modern communication and logistic systems guarantee a quick service and a rapid spare part supply worldwide. 3

4 HOFMANN TechnologyDay & International Expo: Where the world meets Since 2001 the HOFMANN Technology Day annually offers a dialogue forum for road markers, material manufacturers, authorities and ministries as well as for research and education. Hofmann organizes the probably largest worldwide event of this kind each year, thus contributing significantly to bringing together the Who s Who in the sector of road marking technology. The Rellingen-based company has again made it a priority to impress its high-ranking specialist audience with fascinating technical lectures. To ensure that all the international experts will be able to follow the interesting offer, the lectures will be simultaneously interpreted into German, English, Spanish, French and Russian. Five continents amidst discussions concerning technology and progress, technical lectures about road marking developments, the latest machine technology, sophisticated technologies, highly-developed operating controls and more are what make the annual TechnologyDay in Rellingen such a well-known event. Exhibitors are welcome to present their offers on trade booths graphically and tangibly to the audience. 4

44 MALCON4 MALCON4 Electronic control system and documentation unit Control unit for manual, semiautomatic and automatic marking. MALCON4 offers to execute country-specific marking mode up to 3 parallel applied lines automatically. Data export via PDA, USB Stick, printer or even GPS/GSM modul* is possible, in order to prepare marking or line width proofs. A printer can be connected during or after completion of the marking operation to provide a printout for documentation purposes. The operation is selfexplanatory on a graphically brilliant, clearly arranged display. * GPS/GSM module: Localization via GPS and data transfer via GSM. You can change between programmes during the marking operation, whereby the current line-space cycle must be terminated before starting the new programme. Recognition system for direction of travel ensures that whenever the programme step is located inside a space between lines, you can manoeuvre the machine at random without worry. This means that you can be sure of resuming your marking operation again at the correct point. You can activate or deactivate spray guns during the marking operation. You can generate profiled markings in extruder mode, e. g. Spotflex. Operating speeds up to 25 km/h possible. Realization of simulation process (functional test at standstill). In addition, the execution of advance warning line ranges (e.g. before crossing hilltops) can be controlled fully automatically. In case a second parallel running programme (e.g.to execute a drain pipe for rain on the marking during marking operation) is requested, also this is possible with the MALCON4. This means you can mark two different line-gap combinations. Option: Feedback system MALCON4 a multi purpose device consisting of electronic control unit control unit for material quantity documentation unit 44

Manual marking: The operator determines for how long and with which spray guns the marking operation is carried out. Semi-automatic marking: The operator determines with which spray guns and at which point the marking operation is to begin.the operation is terminated after reaching the programmed line length. Fully automatic marking: The machine carries out the marking operation automatically in accordance with the programme the operator has entered. 46

47 Metering technology HOFMANN metering systems comply with even the strictest demands and requirements regarding the observance and verifiability of values given. Constant spraying thickness in spite of varying marking speeds. Constant delivery volume, irrespective of the number of rotations per minute, as well as regardless of pressure and material viscosity. No pulsations (without pulsation dampers). No progressive wear and tear that would reduce delivery volume and make it necessary to calibrate and readjust at regular intervals. This technology was introduced in 1980 under the name AMAKOS. AMAKOS means Application of Marking material with Automatic COnstant Sprayfilm thickness HOFMANN offer the AMAKOS technology for the following methods and marking materials: Spray methods Extrusion Airspray Airless Cold paints 2-component cold plastics Sprayable 2-component cold plastics Thermoplastics Sprayable Thermoplastics 47

48 AMAKOS Path-depending marking system Speed proportional Application of Marking materials with Automatic COnstant of Sprayfilm thickness. AMAKOS mode of operation for constant spray thickness irrespective of any change in travel speed. The delivery rate of material required per metre is adjusted in a control unit (Paint Quantity Device), into which the user enters the required line width and spraying thickness. Non-AMAKOS mode: The delivery rate can also be adjusted manually / hydraulically whilst bypassing the electronic control system which is advantageous in case of an emergency. The delivery rate remains at the set level and does not fluctuate proportionally to the travel speed. CONEX Metering pump system Metering pump for CONstant EXacte metering of different materials. Use of plunger- or bellow pumps according to application technique. For nearly all cold sprayed marking materials with and without mixed-in glass beads / anti skid materials (abrasive materials). In stainless steel version also for water-based materials. No concealed working pistons inside the discharge cylinder, just visually inspectable seals against the outside. Optimum strain effect on the sealing.the stress on the sealing is a stretch load, significant for the application of abrasive materials. No negative pulsation and no flow losses which could be detrimental to the spraying quality. Conveying efficiency of metering pump more than 99 %. 48

49 Path-dependent Airless markings and line width stabilizer Line width stabilizer keeps variation in line width during path-dependent Airless spraying method (AMAKOS ) automatically in minimum ranges. The line width stabilizer is a further special feature and an option in the future for our larger airless machines. HOFMANN pumps for Airless spraying permit variation of marking speed over a large range at a constant paint quantity per metre of line length (AMAKOS ). The paint quantity pumped by the pump is thus proportional to the speed of travel of the machine. Hence, as the speed increases, so too does the quantity of paint that is pressed through the spraying nozzle per unit of time, accompanied by an increase of pressure in the paint pipe to the nozzle. It is well-known that an increase in the spraying pressure results in an enlargement of the spraying angle. With an unchanged distance between the gun and the road surface this results in an enlargement of the line width. This effect is dependent on the nozzle and the paint used. However, due to the pressure influence variator line width variation can be kept within minimum ranges in a large speed area. Functional principle The component marked by an R in the illustration is a frame that always moves parallel to the road surface. The pistol holder with the spray gun fastened to it is connected to the frame via articulated arms. An electrical adjustment cylinder is attached between the frame R and the upper articulated arm and the operation of the same moves the spray gun upwards or downwards. A pressure sensor P continuously records the actual spraying pressure of the paint and is transmitting the values to a control unit, which calculate the height of the spray gun in such a way that the line width almost remains constant even in case the spraying angle varies. With increasing marking speed, i.e. with increasing paint pressure, the spray gun is pushed further and further downwards as a result of which the effect of the enlargement of the spraying angle on the spraying width is compensated. 49

52 Thermoplastic MultiDotLine / MultiDotLine Plus Agglomerate marking Line combinations consisting of continuous and interrupted lines for full-cover markings (plain line) profiled markings defined agglomerate markings defined agglomerate markings on plain lines in one single marking operation (MultiDot-Line Plus). Good descriptiveness of marking patterns (using also e.g. drawings or photographs) improves verifiability during acceptance by the customer. Accurately defined distances between the individual marking dots enable water to drain even easier. Any dirt is thus rinsed from the marking more reliably. The result is better maintenance of the retroreflection values. Variable generation of spaces between dots as well as size of dots. Internal arrangement of scattering device (rotating hollow cylinder) inside of extruder housing in front of extruder slot. Therefore, no problems with cooling down what is common with external scattering devices especially during cold wind. Abrupt begin of line when opening extruder slot. Abrupt stopping of the line when you close the extruder slot, i.e. it is like you operate a normal extruder for plain markings. No splashing of material in undesirable directions what is common with external scattering devices. No splash guard and no drip trays necessary. Filling of a screed box can be executed directly via extruder screw and head. Ensurance of path-dependency (AMAKOS ) with MultiDotLine - and MultiDotLine Plus systems. Application of double lines and line combinations in one single marking operation. High marking speeds. 52
