Definitions
- the present invention relates to a method of making lines on ground surfaces suitable for playing fields and the like, and apparatus and material therefor.
- the lines for such pitches are generally formed by a wheeled paint buggy, which introduces a line of paint on the ground through the travel of the front wheel through a paint reservoir.
- pitches often require newly painted lines every week during a playing season, whereas these lines are often ⁇ losf in the non- playing season as the surrounding grass encroaches, and the pitches are not so regularly mowed.
- Weed or grass killer can be added to the intended line, but because grass is on either side of each line, the grass and weeds still encroach quickly. It will be appreciated the amount of time taken by groundsmen to keep clearing and repainting pitch lines for 120,000 pitches in Ireland alone. It is an object of the present invention to provide more permanent lines in the ground.
- a method of forming a line on a ground surface comprising the steps of: forming one or more slits in the ground surface; inserting a line of material in the or each slit such that part of the material is visible above the ground surface.
- the slit in the ground surface could be formed by any suitable means, one such being a blade, preferably cylindrical, and preferably having a sharpened or tapered edge to assist entry into and through the ground surface.
- the ground surface can be any surface on which a slit can be formed, one such being earth, more generally grassed earth.
- the method comprises forming between two and four slits, preferably three slits, parallel in the ground, so as to create a broader form of ⁇ marked' line.
- the lines can be any suitable distance apart.
- the multiple slits are preferably relatively close, generally within 10-40mm, and such as 20mm, inter-distant.
- the or each slit created preferably creates little or no visible disturbance on the ground surface other than the marked line.
- the ground surface is rolled after the insertion of the or each line of material.
- the material may be any suitable material, at least part of which is visible above the ground surface.
- the material may be any suitable colour, white being the commonest colour for many playing pitches. More than one colour could also be used, in any design or pattern.
- the material visible above the ground surface is partially or at least substantially resistant to sunlight, in particular UV light.
- the material may inherently have a high kilo-langley strength, or be treated so as to have such a high strength.
- the material is at least partly open or has an open structure, through which the ground under the ground surface, or anything growing in the ground under the ground surface, such as the roots of grass, etc, can extend so as to help anchor the material in the slit either immediately and/or over time.
- the material is a polymer material such as polypropylene. Such material is widely available.
- polypropylene textile fibre materials are geotextiles.
- Such materials have moisture resistance so that water has no effect on tensile strength or mechanical properties, extensive chemical resistance, leachate compatibility, biological resistance as polypropylene does not support fungal growth, temperature stability, ultraviolet resistance (preferably by the addition of carbon black or other UV inhibitors), and superior puncture and Mullen burst strength (which make them resistant to installation stresses) .
- One supplier of such materials is Don and Low Limited, Forfar, Scotland.
- the material is preferably inserted in the slit by travel on the slit-forming means. More preferably, the material travels on the edge of the slit-forming means towards and into the surface, and is located in the slit as the slit is being formed.
- At least a portion of the material which is not inserted into the ground surface comprises a number of separate or discrete fibres, or fibre-like extensions. These together provide the visual form of the line, but are wholly or substantially individual like blades of grass. More preferably, that portion of the material above the ground surface is not damageable by a lawn ower or ground trimmer or the like.
- the material could also include a herbicide, such as a weedkiller or the like, which preferably leaches from the material over time, and helps keep the area in and around the ground surface relatively clear. This includes grass.
- the material comprises a woven plastics material, having a central woven portion which is insertable in the ground surface, and extended weft fibres adapted to partially or substantially extended above the ground surface.
- a method of forming a line on a ground surface comprising the steps of: locating a slit-forming means having at least one blade on the ground surface, such that a portion of the blade enters the ground surface; locating a fibrous or woven material on each blade; traversing the slit forming means along the path of the intended line; allowing the material to travel with each blade into the ground; leaving the material in each slit formed such that part of the material is visible above the ground surface.
- the line formed by the present invention is permanent', i.e. remains to form a line for at least a number of years, expectantly greater than ten years.
- the height of the material above the ground can be any suitable height, possibly based on expectation of use. For example, 30-35mm height is generally suitable for many football pitches. Also, some ground surfaces are not flat, and the height of the visible material may be such as to be able to accommodate variation in the level of the surface.
- the present invention extends to a line on a ground surface formed by the method and/or material as hereinbefore described.
- the method, and line thereby formed may be straight or arcuate or any combination.
- the path of the line may follow guide means on the surface, or other markings.
- a direction means may be used, such a light beam, for example a laser beam.
- the beam could be directed along the intended path of the line, and that path then followed.
- the method further includes the step of following a light beam along the path of the intended line.
- a line-forming apparatus which apparatus comprises one or more rotatable blades, each blade being adapted to form a slit in the ground surface, and adapted to feed around its edge a material for partially inserting into the slit.
- the apparatus includes a roller following the or each blade, more preferably two or more rollers on which the apparatus traverses along the ground surface.
- the apparatus could also include a line-direction means, or line-direction means receptor, such as a laser beam, or a laser beam screen.
- a line-direction means such as a laser beam, or a laser beam screen. The user of the apparatus then follows the path of the beam to create a straight line.
- a material as hereinbefore defined to make a line on a ground surface.
- the material could be made from any material including plastics.
- the material is a polyolefin such as polypropylene or a co-polymer, more preferably a geotextile.
- a vented fabric material suitable for use in forming a line on a ground surface.
- the vented fabric material comprises warp and weft fibres, having a core section or solid centre line, and free weft fibres or tapes on each side.
- the free weft fibres are designed to be that part of the fabric material that partially or substantially extends above the ground surface.
- the material is preferably a woven plain material, more preferably a non-fibrolated tape.
- Typical but not-limiting qualities include 97 and 47 warp and weft ends per 10cm, 125g/m 2 density, and 50 tex striped warp, and 220 tex white UV weft fibres.
- the vented fabric material could be formed from a fully woven material, from which warp fibres are removed from each side to provide ⁇ free' portions of the weft fibres.
- a process for forming a vented fabric material as herein before described wherein lines of weft material are run, and intermittent lines of warp fibres are run thereinbetween, so as to form portions of woven material and portions of weft fibre material only.
- Such a material can then be cut across each weft fibre portion, to create a vented fabric material having a woven core portion, and free weft fibres on each side.
- a catch thread included which holds the warp threads in place.
- the process provides periodic weaving, or non- weaving, periods.
- Figure 1 shows marked lines in a grassy earth surface according to one embodiment of the present invention
- Figures 2a and 2b are diagrammatic cross-sections of the ground in Figure 1 along Arrows A & B respectively
- Figure 3 is a side view of apparatus according to another embodiment of the present invention
- Figure 4 is an enlarged part view of part of the apparatus in Figure 3 in use
- Figure 5 is a plan view of the apparatus in Figure 3.
- Figure 6 is a schematic plan view of a vented fabric method of production according to another embodiment of the present invention
- Figure 7 is a section of vented fabric prepared from the process of Figure 6.
- Figure 1 shows marked lines 2 in a grassy earth-surface 4 as an illustration of the effect of the present invention.
- the marked lines could be used as pitch lines for the corner of a soccer or gaelic football pitch.
- Figure 2a shows a cross-sectional view through the ground 4 across the path of the marked line 2 in Figure 1, showing the location of three lines of white material 6 in the ground surface 4.
- Figure 2b shows a longitudinal cross-section of the marked line 2 of Figure 1 along Arrow B. These figures show the material 6 having a woven section 10 which is within the ground surface 4, and the free fibres 12 extending therefrom, the ends of which 19 are visible above the ground surface 4.
- figurative grass 8 is shown each side of the line 2, although the relative heights of the grass 8 and the parts of the material above the ground surface 20 are for illustrative purposes only.
- Figure 3 shows apparatus comprising three cutting discs or blades 30.
- the blades 30 are rotatable about separate axles 32.
- the axles 32 are parallel and offset as shown in Figure 5.
- the interdistance of the blades 30 could be approximately 20mm apart, which distance is adjustable.
- the three blades 30 are generally housed within a ballast frame 34. At the forward and rear ends of the frame 34 are round surface rollers 36. Above each blade 30 is a spool carrier 38, each having a spool tensioner 44.
- Each blade 30 forms a slit in the ground surface 4 by traversing the ground surface 4, for example by being pulled by a tractor or the like through a linkage. As each blade 30 is pulled, it rotates about its axle 32, and so cuts through the ground surface 4.
- Feeding onto each blade 30 from the associated spool carrier 38 and through weave tensioners 46 is a folded woven polypropylene material 40 approximately 200mm wide, having a central woven band approximately 70-80mm wide, and free weft fibres extending from each side of the central band. Example dimensions are 65/70/65mm of free fibres and central core.
- the material 40 is shown diagrammatically in Figure 3, but is the same as that shown in Figures 1, 2a, 2b and Figure 7 hereinafter.
- Fully woven polypropylene is used for forming bales or agricultural flexible sacks and the like.
- the folded material 40 follows the edge of the blade 30 and is therefore fed into the ground surface 4 as the blade 30 enters also.
- the force of the blade 30 locates the folded central woven section 10 of the material 40 in the slit formed, which part of the material 40 then remains in the ground surface 4 whilst the edge of the blade 30 exits the ground surface 4.
- the free ends 48 of the material 40 like those 20 in Figures 2a and 2b, are however now visible whilst being securely retained in the ground surface 4 as the ground folds back around the remaining part of the material and holds it in place.
- roots and the like can grow through the part of the material 22 in the ground surface 4, due to its open structure, increasing its securement in the ground.
- the apparatus or apparatus-pulling means such as the tractor, could be laser guided by a laser set at the end of the intended path of the line, whose beam hits a receptor such as a screen on or near the apparatus etc.
- the screen is noted by the user in use, and the beam maintained within the screen, or limits set on the screen, to ensure the apparatus follows a straight line.
- Figure 6 shows a process for forming a vented fabric material as used in Figures 2a and 2b, etc wherein lines of weft threads 52 are constantly run, whilst only intermittent lines of warp threads 50 are run thereinbetween; the line of production being towards arrow C.
- two pieces of vented fabric material 56 one of which is shown in Figure 7, is formed.
- Each piece 56 is useable for the method and with the apparatus hereinbefore described. That is, the extended or free weft threads 58 are the ⁇ free fibres' 12, 48 shown in Figures 1, 2a 2b, 3 and 4, and the woven core 60 is the woven section 10, once the piece 56 is folded longitudinally in half.
- the present invention has been found to lay the complete lines of the football pitch within a day, which lines then need no further maintenance or repair.
- the free fibres 12,48 extending above the ground surface will not trip or catch any player, such as by his boots studs.
- the free fibres 12, 48 cannot be cut by a lawnmower such that mowing any playing pitch is not a problem.
- the present invention provides a simple but effective means of providing marked lines, which lines will remain, and need no further repair or maintenance for a number or years, while still providing the same visual effect as painted line.
