Definitions
- Ball games such as football, hand- and basketball, hockey, cricket, baseball and the like, are played on grass fields, and the quality of the grass surface and of the subsoil will have an influence on the behaviour of the ball, such as its bouncing and rolling.
- a natural grass surface if well kept, can be played on for not more than 250 h per year, and even in the best maintained fields the most heavily strained parts, in particular near the goals, will be bare at the end of the playing season.
- artificial grass has been developed of late.
- This comprises webs, e.g. with a width of 4 m, of a carpet-like material, consisting of a carrier or substrate made of planar plastic material with loops of strip-like parts of plastics having the colour of grass being inserted therethrough and being fixed in the plastics carrier by means of additional carrier material.
- the carrier can be slightly permeable for water.
- Said webs are juxtaposed on a suitable plane subsoil, consisting of compacted porous material such as granulated lava or the like, the adjacent webs being glued on an underlying connecting strip.
- weighting sand is provided between the artifical grass parts, which, in particular, can also prevent the grass surface from locally shifting as a consequence of sliding movements of the players.
- the playing area is defined and divided into sections by means of lines.
- lines are made with lime which is cheap and does not substantially damage the grass, which lines, depending on the utilisation degree, rain-fall etc., are to be renewed several times each season.
- lime will not stick to artificial grass, but then stronger paints such as polyurethane paint can be used, which, in the case of living grass, cannot be utilised.
- the playability of artificial grass is more than ten times better than of natural grass, such lines will wear off faster accordingly. Renewing them is, however, much more expensive than in the case of lime.
- Another objection of the current methods for placing such artificial grass surfaces is that it is difficult to distribute the weighting sand evenly, which is particularly important if in the artificial grass webs strips of a different material are to be included where for the reasons mentioned before weighting is particularly important.
- the artificial grass parts are removed down to the vicinity of the carrier layer at the marking lines to be formed, after which strips of flat carrier with artificial grass parts of a different colour fastened thereto are glued on the exposed carrier surfaces formed on the webs. Said strips being preferably arranged with the same pile direction as the adjacent artificial grass material.
- the differently coloured artificial grass is, preferably, cut out from the webs in such a manner that the pile direction thereof corresponds to that of the adjacent webs.
- the sand is applied between the artificial grass parts by raking up the latter against the-pile direction by means of a knife, and to allow the sand to flow as a narrow flow between the artificial grass parts thus erected immediately thereafter.
- the invention provides a tool for shearing off the pile material, comprising a carriage movable on wheels with a disc knife mounted thereon having a diameter corresponding to the strip width which knife can be driven by a motor at a high speed, in particular of about 3000 min- 1 , as well as a blower for generating a strong air flow by means of which cutoff parts can be sucked away, and, at the same time, the vicinity of the cutting disc is cooled in such a manner that no substantial softening of the plastics will occur.
- the knife is arranged at such an inclination that its cutting edge is supported at a suitable angle close to the upper side of the carrier, and its hub remains free from the shorn carrier so as to avoid additional friction and to provide an unobstructed passage of the cooling air.
- the invention provides a tool for applying the glue in the strip-shaped part of an artificial grass surface shorn according to the invention, said tool comprising a slot-shaped nozzle having the width of the formed strip, which nozzle is connected to a glue container which is, in particular, pressurised, said nozzle preferably comprising an interrupted slot thus allowing to produce a plurality of parallel mutually separated glue ridges which, when pressing a strip to be glued thereon, can flow out laterally.
- the invention provides a tool for applying sand on an artifical grass surface, in particular at the strips glued therein, which tool comprises a movable carriage provided with a brushing knife directed hansversely to the direction of movement with a lower edge directed parallel to the bottom, said brushing knife being adapted to be brought into contact with the artificial grass parts in order to erect these parts against the pile direction, whereas above this brushing knife sand can be poured into the interspaces between the artificial grass parts erected by the brushing knife.
- FIG 1 a cross-section of a small part of an artificial grass web is diagrammatically shown.
- This web having a width of, for instance, 4 m, comprises a carrier 1 made of flexible plastics through which strands 2 of toughly resilient plastics strips resembling grass are inserted which, at the lower side, are anchored by means of an additional plastics layer 3.
- the carrier 1 is, generally, porous in such a manner that water can flow off towards the subsoil.
- Such artificial grass surfaces are known.
- FIG 2 the successive steps in providing wear resistant lines in such a grass surface are diagrammatically indicated.
- A the artificial grass parts 2 are cut off in a strip 4 with the desired line width and down to the immediate vicinity of the carrier 1. How short the artificial grass is cut depends on the characteristics of the used tool and the regularity of the surface of the carrier 1 which should not be damaged.
- glue ridges 5 are provided on the shorn part as indicated at B, after which, as shown at C, a strip of a similar artificial grass material having the same strip width but a different colour is pressed on the glue ridges 5, the latter being such that the glue will be spread out regularly and will not substantially be pressed outwards beyond the strip 6.
- the artificial grass parts 2' of the strip 6 can, if necessary, be made a little shorter than the parts 2 of the grass surface proper, but longer parts 2' will wear faster so that, eventually, a uniform length will be obtained.
- the strips 6 are cut from webs so that the pile direction of the parts 2' will be equal to that of the parts 2 of the adjacent grass surface parts.
- curve segments are cut from webs having the same direction as the grass surface webs in which said lines are to be provided. Cutting or shearing the artificial grass parts 2 is difficult since, during cutting, the plastics becomes soft.
- Figure 3 shows a tool according to the invention developed for the present purpose which does not have these draw-backs.
- the tool according to Figure 3 comprises a carriage 7 with wheels 8 which, for instance, can be guided on guiding bars to be arranged along or on the grass surface, whereas in the case of curved lines the carriage can be maintained in the desired track by means of a rod or wire attached to a pin driven into the ground in the centre of the curve.
- a cutting disc 9 with a driving motor 10 is mounted, which assembly is preferably adjustable in such a manner that the cutting edge 11 of the disc is maintained at the desired height.
- the disc has such an inclination that the bevel of the cutting edge 11 is substantially parallel to the carrier 1, and the hub 12 of the disc 9 remains free from the carrier so as to avoid additional friction leading to melting of the plastics.
- the cutting edge 11 is provided with suitable teeth.
- the whole assembly is enclosed within a hood 13 which, by means of a blower 14, is connected to a collecting vessel 15 for the cuttings.
- the blower can, for instance, be connected to the motor 10, but can also be provided with a motor of its own. Apart from sucking away the cuttings, the air flow thus produced will bring about cooling of the plastics material which. comes into engagement with the cutting disc 9, the inclination thereof being such that also from the side of the hub air can flow onward.
- the rotational speed of the cutting disc is preferably about 3000 min- 1.
- the glue ridges 5 according to Figure 2B can be applied by means of the nozzle 16 shown in Figure 4, having a width corresponding to the width of the strip 4, the outflow openings 17 of the nozzle corresponding to the location and width of the ridges 5.
- the nozzle 16 is connected, by means of a hose 18, to a glue containing pressurised tank.
- the nozzle can, for instance, be held by means of a stick, and can be provided, if necessary, with one or more running wheels.
- FIG. 5 shows a tool according to the invention designed for that purpose, provided with a carriage 19 with wheels 20.
- a brushing knife 21 is mounted which is directed transversely to the direction of movement, and which, when the carriage 19 ⁇ is moved against the pile direction, will erect the parts 2 and 2' pressed flat.
- a sand funnel 22 with a slot-shaped spout 23 is present, by means of which the sand can be poured on the carrier 1 behind the erected parts 2 and 2'.
