Definitions
- the invention relates to a covering for tennis courts or similarly stressed sports fields, which has a loose particle bed containing plastic particles on its surface, and a method for producing these plastic particles.
- a sports field covering particularly suitable for tennis courts, was proposed in CH-A-611 959, in which a backing layer is provided in which stabilizing grains e.g. made of rubber are firmly embedded, which protrude from the carrier layer by about a third of their height dimension.
- a relatively thin outer layer of fine rubber granulate with a grain size of 0.5 to 1.5 mm is then applied to this carrier layer, which fills the gaps between the stabilizing grains protruding from the carrier layer and covers their tips. If the athlete now pulls away from the surface, the tips of the stabilizing grains are caught by the profile sole of the tennis or sports shoe, which e.g. allows a perfect impression when starting.
- the invention seeks to remedy this.
- the invention as characterized in the claims, solves the problem of creating a covering for tennis courts or similarly stressed sports fields, which has a loose bed of plastic particles on its surface, and to provide a method for producing these plastic particles, wherein the covering largely any flat solid surface, such as on asphalt, can be applied and, if necessary, removed from it again and which is just as pleasant for the athlete in use as a brick meal place.
- the invention also achieves the object of specifying an advantageous method for producing plastic particles which are particularly suitable for use in these loose fillings.
- a covering according to the invention which has the desired properties can only consist of a loose bed of particles based on an elastic plastic or a crosslinked rubber, if at least the majority of the particles used are in the form of flakes or scales.
- the elastic plastic is based on a thermoplastic polyurethane elastomer and / or a one- or two-component polyurethane system and / or a thermoplastic rubber and / or a modified PVC compound.
- particles based on an elastic plastic or a cross-linked rubber is intended to indicate that the particles can contain fillers, aging agents, stabilizers, processing aids, dyes and / or pigments as well as inorganic additives in addition to the plastic.
- Particles of this type have only a slight tendency to curl, which on the one hand favors a stabilization of the bed on the ground and, on the other hand, leads to an increased braking effect with the desired slight sliding when the athlete decelerates. In addition, turning the leg is made much easier.
- the bed is advantageously a few millimeters thick. Good results can also be obtained if the bed is only applied to the level solid surface in the form of a finish, whereby the surface of the surface may not be completely covered by the particles, so that the boundary lines applied to the solid surface are still despite the bed are clearly recognizable.
- the amount of particles applied to these finish beds is advantageously in the range between 0.2 to 0.6 kg / m 2 .
- a plastic tape 1 is assumed, the thickness of which is equal to one of the dimensions (e.g. the thickness) of the particles to be produced.
- the plastic strip 1 is pulled off the roll and continuously advanced with its front edge 2 over a fixed shear bar 4 provided with comb-like toothed cutting edge 3.
- a rotor equipped with one or more flyknives 5 works together with this bedknife 4, the cutting edges 6 of the bedknives 5 also being toothed and cooperating with the cutting edge 3 of the bedknife 4.
- the impact knife 5 rotates, the plastic particles 7-e.g. are then removed from the front edge 2 of the continuously advanced plastic strip 1. in the intended plate shape - separated.
