The multilayer anti-slip compact structure consists of backing carrier A and anti-slip layer B applied thereon. The backing carrier A with anti-slip layer B applied thereon as product has a shape of tape or patch.

(51) By combining examples 1 and 2 a multilayer anti-slip compact structure for hockey stick blade with a backing carrier with fibre net structure and with the simplest anti-slip layer consisting only of resin is formed, as presented in FIG. 5.

(52) By combining examples 1 and 3 a multilayer anti-slip compact structure for hockey stick blade with backing carrier with fibre net structure and resin anti-slip layer containing coarsening grains 6, is formed, as presented in FIG. 6.

(53) By combining examples 1 and 4 a multilayer anti-slip compact structure for hockey stick blade with backing carrier with fibre net structure and resin anti-slip layer, containing coarsening grains 6, covered by a synthetic abrasion resistant layer 7, is formed, as presented in FIG. 7.

Example 6

(54) This example of the specific realization of the subject matter of this invention describes the second backing carrier A for application of the anti-slip layer B on hockey stick blade, as presented in FIG. 8. This backing carrier A of the anti-slip layer, has two layers. The first layer is formed by a polymer plastic film 1, for instance from polyester, thickness max. 0.3 mm and tensile strength min. 400 N and weight max. 130 g/m.sup.2. To this first layer formed by the plastic film 1, the second resin layer 3, with thickness max. 0.1 mm with a content of: polyacrylate is applied. The reverse side of the plastic film 1 has an adhesive layer 4 with thermal resistance from −15° C. to +40° C., which does not leave any residues (adhesive residues) on the hockey stick blade.

(55) Another alternative solution provides transparent first layer of the backing carrier A and the second resin or glue layer 3 of the backing carrier A of the anti-slip layer B for hockey stick blades with the purpose of visibility of advertisement placed under these layers.

(56) In the next alternative, it could be possible to consider this semi-product as product, if to this semi-product coarsening grains 6, for instance of corundum, hard plastic and glass and so on would be applied individually or in a combination.

Example 7

(57) This example of the specific realization of the subject matter of this invention describes the first anti-slip layer B for application to the above described backing carrier A from examples 1 and 2 and 6. The first anti-slip layer B is presented in FIG. 2. This layer has a third resin layer 5 with thickness max. 0.1 mm and weight max. 250 g/m.sup.2 with content of epoxide and phenol, this means epoxy resin based on bisphenol A and/or suitable polymer. The reverse side of the third resin layer 5 has or as an alternative does not have any adhesive layer 4.

Example 7a

(58) This example of the specific realization of the subject matter of this invention describes the first anti-slip layer B for application on the above described backing carrier A from examples 1 and 2 and 6. The first anti-slip layer B is presented in FIG. 2. It is formed by the third resin layer 5 with thickness max. 0.1 mm and weight max. 90 g/m.sup.2 with a content of epoxide and phenol, this means epoxy resin based on bisphenol A and/or suitable polymer. The reverse side of the third resin layer 5 has or as an alternative does not have any adhesive layer 4.

Example 8

(59) This example of the specific realization of the subject matter of this invention describes the second anti-slip layer B for application to the above described backing carrier A from examples 1 and 2 and 6. The second anti-slip layer B is presented in FIG. 3. This layer has a third resin layer 5 with thickness max. 0.1 mm and weight max. 250 g/m.sup.2 with content of epoxide and phenol, this means epoxy resin based on bisphenol A and/or suitable polymer. Furthermore, it contains coarsening grains 6, covering max. 50% of its surface. The reverse side of the third resin layer 5 has or as an alternative does not have any adhesive layer 4.

Example 9

(60) This example of the specific realization of the subject matter of this invention describes the third anti slip-layer B for application to the above described backing carrier A from examples 1 and 2 and 6. The third anti slip layer B is presented in FIG. 4. This layer has a third resin layer 5 with thickness max. 0.1 mm and weight max. 250 g/m.sup.2 with content of epoxide and/or phenol. Furthermore, it contains coarsening grains 6, covering max. 50% of its surface and finally is covered by a synthetic abrasion resistant layer 7. The reverse side of the third resin layer 5 has or as an alternative does not have any adhesive layer 4.

Example 9a

(61) This example of the specific realization of the subject matter of this invention describes the third anti slip-layer B for application to the above described backing carrier A from examples 1 and 2 and 6. The third anti-slip layer B is presented in FIG. 4. This layer has a third resin layer 5 with thickness max. 0.1 mm and weight max. 80 g/m.sup.2 with content of epoxide and hardener. Furthermore, it contains coarsening grains 6, covering max. 50% of its surface, has weight 10 g/m.sup.2 and the size according to the FEPA standard P220 (this means approximately 68 micrometres) and finally covered by a transparent synthetic abrasion resistant layer 7, which contains epoxy resin and hardener.

Example 9b

(62) This example of the specific realization of the subject matter of this invention describes the third anti slip-layer B for application to the above described backing carrier A from examples 1 and 2 and 6. The third anti-slip layer B is presented in FIG. 4. It is formed by the third resin layer 5 with thickness max. 0.1 mm and weight max. 80 g/m.sup.2 with content of epoxide and/or phenol. Furthermore, it contains coarsening grains 6, covering max. 50% of its surface, have weight 32 g/m.sup.2 and size according to the FEPA standard P120 (this means approximately 125 micrometres) and finally covered by a synthetic abrasion resistant layer 7, which contains epoxy resin and hardener.

(63) Comparison of weight and thickness of the specific final product (adhesive layer protected by a liner+backing carrier, third anti-slip layer, coarsening grains) to alternative products in the market:

(65) As it is obvious from the table above, product which used this invention has excellent thickness as well as weight, plus it has much better properties from the point of view of its durability, puck control, soaking and catching ice and snow.

INDUSTRIAL APPLICABILITY

(66) Industrial usability of the backing carrier, anti-slip layer and multilayer anti-slip compact structure for individual/joint application on forehand and/or backhand side of the hockey stick blade according to the invention, can be used for all sports, using hockey or other similar stick. It could be produced in serial production and used for instance during production of tapes or stickers for hockey stick blades, applied with the purpose to make blade more coarsened.
