Definitions

  • ABSTRACT The specification describes a device designed for travelling along a given path on a road surface for laying down on and adhesively securing to said surface a traftic-regulating line or similar mark means.
  • the device comprises a service unit in form of a motor-van equipped with supply means and an operative unit trailed and supplied by the service unit and provided with means for forming on the road surface a primer layer wider than the line to be marked and having thermal energy, and with means for laying down and pressing a marking tape material on said primer layer, the thermal energy of which promotes a quick modification of state at the interface between said layer and tape to cause prompt adhesion of said tape to said layer and of said layer to said road surface.
  • this invention is concerned with improvements relating to the manner and means for quickly and effectively producing on an uneven and porous road surface a layer most adapted for forming an impervious and smooth surface for having the tape mate rial laid thereon and most promptly adhesively and permanently secured thereto.
  • this invention is also concerned with a new and improved apparatus adapted for displacement on the road surface along a path corresponding to the traffic-regulating line to be formed, the apparatus being adapted either for regular travel on roadway as a quite conventional road motor vehicle does, when not engaged in the marking operation, and for exceptionally fast and uninterrupted trafficdirecting line formation, by uninterruptedly operating for also exceptionally extended lengths of marking.
  • the Prior Art The road marking material in strip form, of essentially elasto-plastic composition and provided by manufacturers in spools or bobbins, is well known.
  • the advantages of such materials, in comparison with road marking by painting signs on the road surfaces or by pouring hot-melt or otherwise fluidified marking compounds on the road surface, where the compounds set to form the marking, are well known to those skilled in the art, and further comments therabout are unnecessary.
  • the prior art apparatus and methods are subject to several objections and limitations.
  • the apparatus are pretty costly, bulky and complicated, and smaller and simpler ones has not proved to provide a desirable efficiency and fast operation either as the speed at which the tape laying vehicle is capable of travelling along the given path on the road to be marked and as the promptness and the sureness of adherence of the tape material on the road surface are concerned.
  • road marking is an operation which can be made here and there, even far from the place where the apparatus are usually recovered and worked for maintenance and preparation for operation, and in locations at substantial distance from each other;
  • 2nd To be capable of uninterruptedly laying down relevant lengths of marking tape, well over the length of tape wound on one bobbin or spool, and to require simple and minimum time-consuming operations for refuelling and reloading the materials necessary for service, that is the apparatus should be such to provide a high time/operation ratio, together with a minimum of traffic disturbance, that is of time during which the apparatus actually operates on the road;
  • 3rd To provide an extremely prompt setting of the marked line on the road surface, that is, most desirably, to operate so that the marked road surface can be reopened to traffic, newly marked areas inclusive, as soon as the apparatus has been passed over and has the marked line laid on and secured to said areas; and 4th To require, for its operation, few personnel, in particular a crew of two or possibly of three average skilled men, and to avoid or minimize laborious, fatiguing and dangerous manual operations, while refuelling and supplying the apparatus, made with the help of an additional crew, can be quickly made on the road.
  • Another object of this invention is to provide a new and improved apparatus and method by which the laid down tape marking material is so arranged and secured to a tape receiving layer that the interface between said tape material and said layer, wherein an adhesive connection is provided, is fully protected against water, moisture, oils, gasoline and other destructive agents penetration, together with complete protection of the material side edges, that is of the parts which are most subject to wear and damage by the traffic.
  • the improved linemarking apparatus consists of the combination of a service unit and of at least one operative unit.
  • the service unit comprises a suitably equipped and implemented self-propelled and load-carrying road vehicle, such as a motor-van, and the operative unit is provided with means adapted to form on the road surface a primer layer adapted to have the tape material laid on and adhedively secured to its upper face, and to lay and press said tape material on said face, while the said service and operative unitsr un concurrently along a given path of the road surface, and the operative unit is con,- tinuously supplied by the service unit with the tape and the primer layer formingmaterials, as these same. materials are transferred to the road surface to form the said primer layer and the strip marking thereon.
  • the operative unit comprises heating means supplied with fuel by the service unit and arranged to overheat a primer layer forming a fluidified composition supplied by the service unit and pump and nozzle means for ejecting said overheated composition on selected areas of the road surface to form on said surface a primer layer wider than the marking tape, the excess heat of the thus formed primer layer being made use of for promoting an abrupt modification of the physical and/or chemical state of the material adjacent to the interface between the said primer layer and tape as said tape is being laid and pressed on said primer layer.
  • the said service unit and operative unit are connected together by universal joints positioned to provide that the operative unit is trailed by the motorvan forming the service unit, for operating along the desiredpath, and the said motor-van has collimating means arranged at its fore end to facilitate steering of the van along such path, as defined by the traces or residual portion of a worn off traffic-directing line to be renewed, for example, or by signs or marks provided on the newly made or renewed covering of the road surface.
  • the said service unit forming motor-van is equipped with means for rotatably supporting a plurality of spools or bobbins of marking tape, and with means for successively guidedly transferring the tape material as successively unwound from each individual spool to the operative unit for facilitating uninterrupted operation along relevant lengths of road.
  • the service unit carries also suitable supplies of fuel (preferably liquified gas fuel), of pressurized air (preferably an air compressor) together with the materials and compound necessary to form the primer layer and to adhesively connect the marking tape thereon.
  • a composite apparatus as above is therefore designed for operating according to a new and improved method for effectively providing traffic-regulating lines on road surfaces.
  • This method includes the steps of preliminarily forming a primer layer wider than the tape on the road surface, of providing excess heat in the thus formed layer, of applying and pressing the marking tape on this layer when still hot to promote a state transformation at the thus formed interface and consequently promoting essentially immediate adhesion of the tape on said layer, the pressing of said tape on the wider primer layer when still in essentially plastic state causing embedding of the tape in the layer, the side edge portions of which will sidewardly cover and protect the side edges of the laid down tape.
  • a covering sheet of paper or other laminar material is also laid down on the marking tape and the primer layer to temporarily protect such material and to prevent the pressing means, such as one or more rollers, to contact the still plastic primer layer edges.
  • FIG.. is a diagrammatical side view and partly a longitudinal sectional view of an apparatus constructed and operable according to the invention
  • FIG. 2 is a fragmentary side view of an ancillary unit adapted to complement the apparatus of FIG. 1 to meet some modified procedures of road marking;
  • FIGS. 3, 4 and 5 are fragmentary perspective sectional views of the materials as laid down on and secured to the road surface at the various steps of road marking;
  • FIG. 6 is a vertical longitudinal sectional view of a preferred combination of means provided in the service and operative units, in a modified embodiment of the invention.
  • FIG. 7 is a rather diagrammatical longitudinal sectional view of the means provided in a preferred form in the operative unit and designed for laying down the primer layer, preparatory to laying down and securing of the marking tape.
  • the apparatus of the invention is designed to form a continuous or interrupted traffic-regulating line (or an equivalent marking) on a road surface S.
  • This operation comprises forming first an uniform, impervious and essentially smooth surface 10, of width Ls wider than the width Lm of the tape material to be laid down, by applying a primer layer 12 of suitable composition on said surface S.
  • the tape material 14 is then laid and pressed on said primer layer 12, and temporary protective sheet material 16 is applied above said tape 14 and the parts 12' and 12" of the primer layer 12, extended sidewardly from the tape, the sheet material 16 being of width Lp greater than the width Ls of the primer layer to provide side portions 16 and 16" which directly contact the road surface S.
  • the tape material 14 Upon removal of the sheeting 16 (FIG. 5), the tape material 14 will thus provide a marking strip the surface M of which is flush with the surface 10 and 10 of the side portions 12' and 12" of the primer layer. Said side portions can also go over the lever of said marking surface M, as the said tape material 14 is downwardly pressed into the primer layer 12 when such layer is still in its plastic state. Therefore, the marking tape 14 will be completely protected at its side edges also, that is where moisture and oil penetration might occur and where the tape is most subject to be worn off or otherwise damaged by the traffic.
  • the primer layer (FIG. 3) is formed upon a completely dried and preliminarily heated road surface.
  • This road surface preparation comprises directing towards the selected areas of said surface a jet of flame, as provided by a suitable burner.
  • This jet ensures the elimination of water, moisture, lubricating oil and generally of any substance which could hinder the proper connection of the primer layer 12 with the road surface, and provides a warm means on and within which the primer layer material can intimately permeate, by deeply filling the pores and surface cavities;
  • the composition prepared to form the primer layer 12 (a few examples of such compositions will be given below) is directed onto said heated road surface S from above in metered amounts.
  • This composition supplied in fluidified and preferably pressurized state by the service unit, is preliminarily heated in a heat-exchanger in the operative unit, until an excess of heat is imparted to such composition, and then ejected under pressure onto the surface S for impingement thereon.
  • the thus impinging and essentially fluid composition will intimately connect itself to said road surface;
  • this composition comprises components adapted to react and provide an essentially thermo-setting material which promptly sets as such primer layer is formed, while the said excess of heat is at least partially transferred to the tape material laid down on said primer layer for promoting activation and setting of the adhesives (either in solid or in highly viscous state) provided at the lower face of the tape material, for promptly completing the adhesive connection of the tape to the primer layer;
  • the apparatus comprises a service unit consisting of a suitably implemented motorvan generally indicated at 20, and a twin operative unit consisting of a primer layer forming device 22 and of a tape material laying down and pressing device 24.
  • This latter device comprises at least a tape applying roller 26 and a suitably heavy pressure roller 28 to apply and press the tape material 14 on the primer layer face provided by the device 22.
  • the temporary protective sheet material 16 is laid down concurrently with the tape 14 and can be supplied, for example, by a spool 30 carried by same device 24.
  • This sheet material 16 may consist of a thin plastic film or preferably of a paper ribbon, which can be left on the road where it will be promptly torn off and eliminated by the traffic.
  • the apparatus comprises also means for providing such elimination, such as a burner 36 carried by a rearwardly extended brace 32 of same the device 24.
  • Such sheet material can be however recovered, such as by rewinding it about a spool, for example, if consisting of pretty costly and re-utilizable material, such as a pretty thick polyethylene sheeting.
  • composition of the primer layer, the material of the marking tape and the adhesive are so selected to provide the most prompt setting of the marking, so that upon or shortly after the removal of the sheeting 16 the marking will not be damaged by traffic and the thus uncovered portions 10' and 10" of the primer will no more be tacky.
  • Such separate vehicle can consist of a separate motor-van (FIG. 2) pulling an ancillary device which carries the burner 136 (or other sheeting eliminating means) and preferably a further pressing roller 128 to complete the pressure and flattening of the marking material before leaving it subject to the traffic.
  • a separate motor-van FIG. 2
  • ancillary device which carries the burner 136 (or other sheeting eliminating means) and preferably a further pressing roller 128 to complete the pressure and flattening of the marking material before leaving it subject to the traffic.
  • the service unit is provided with means for facilitating the displacement along the required path.
  • means for facilitating the displacement along the required path include for example a sight or collimator 40 supported well forward of the vehicle fore end by a brace 42, for example, connected to the steering mechanism of the motor-van, so that the driver of the van can precisely follow a tracing line.
  • This sight can obviously be sidewardly displaced with respect to the vehicle if the primer layer forming and the tape material laying devices 22 and 24 are in turn positioned to form the said layer and marking laterally of the tracks of the same service vehicle 20.
  • the said service van 20 is designed for actually servicing the devices 22 and 24 in operation, in addition to pulling the same and to provide transportation for the same devices, to and from the various locations where the marking operations are to be and have been made. Therefore, the van 20 is provided with means for rotatably supporting a plurality 46 of spools of marking tape 14. Preferably, such spools are co-axially supported about a mandrel arranged horizontally and longitudinally in the motor-van body. Above said plurality 46 a guide roller 48, rotatable about a horizontal axis transversal to the van, is displaceably supported, in the direction indicated by the arrows in FIG.
  • the apparatus can substantially uninterruptedly operate for providing very substantial lengths of marking, simply by joining the trailing end portion of a tape stock unwound from the emptied spool to the leading end portion of another stock of tape unwound from a spool adjacent to the emptied one.
  • the van 20 might have tape spools differently arranged thereon, for example rotatably supported about individual mandrels transversal to the van, such as shown at 46a in FIG. 6, wherein there is also shown a tape being pulled in direction A from the spool to a guide roller 54 carried by the device 24, the pull, and therefore the supplying of the tape, being simply ensured by the displacement of the apparatus in direction V, owing to the fact that the portion of same tape, already laid down on the primer layer 10, is secured thereto and provides the necessary pulling action.
  • the laying down .of the tape has been discontinued, by simply engaging the tape (manually or mechanically) under the applying roller 26 the required pull and laying down of the marking tape will be restored.

  • It may comprise a device 56 (individually known in the art) for applying a highly viscous adhesive to the face of tape 14 just before its contact with the primer layer, if such tape is not provided with an adhesive in solid and non-tacky state on its lower face, such adhesive being of the type susceptible of activation under the action of heat and/or of the chemicals comprised in the not yet set primer layer.
  • the device 24 can be provided with the above discussed means 32 and 36 and with a heat for accomodating the crew which controls and provides for the necessary actions.
  • the device 22 comprises a first burner 62 providing a jet of flame F on the road surface S and a nozzle assembly 64 to direct metered amounts of the compound G onto the heated surface for forming the primer layer 10, said burner and assembly being supplied by the service units through suitable flexible ducts 66 and respectively 68.
  • the first burner 62 comprises a burner body 70 co-axially located above a frusto-conical flame diffuser 72 wherein secondary air is supplied to the flame.
  • Such diffuser 72 has metal twin walls forming an interspace 74 wherein pressurized air (supplied by the service unit) is fed through a duct 76, in direction B. This air cools the diffuser and protects it against overheating and, upon having been heated in said interspace 74, is then fed, through a duct extension 76a, into a chamber 78 arranged about the nozzle 80 from which the primer layer compound is caused to issue.
  • This chamber 78 has a downwardly open passage co-axial to said nozzle so that the issued compound will be confined within a hot gaseous medium which prevents anticipated heat dissipation from such compound to provide the desired excess heat in the formed primer layer 10.

  • This heat exchanger has an outer shell forming an interspace 90 wherein the compound passes and is heated by a flame issued by another burner 94 within an inner tubular shell 92; the said other burner 94 is fuelled through a side extension 66a of the duct 66 from the service unit.
  • a valve 98 in a by-pass 96 of pump 82 and a valve 100 in the duct 66 can discontinue the operation of the device, upon control applied by means of suitable control means, diagrammatically indicated at 102, 104 and 106.
  • valves 98 and 100 (such as remotely pneumatically or electrically actuated valves) will be so controlled by conventional control means (such as diagrammatically indicated) that valves 98 will open, to by-pass and feed back the out-put of pump 82, while valve 100 will close the fuel supply to burners and 94. Further, the discontinuing of the operation of device 22, concurrent with discontinuing of layingdown of the tape material, will usually occur for brief times.
  • valve 100 will not completely close the fuel supply (a by-pass of small cross-sectional area, not shown, might be provided for) so that a minimal amount of fuel will be maintained to the burners, for keeping them alive for subsequent full activation, and for continuously supplying heat to the amount of compound standing in the interspace 90, ready for the same re-activation.
