DETAILED DESCRIPTION

(9) A schematic top view of a section of a reinforcement stripe 1 of a masonry reinforcement can be found in FIG. 1A. According to the technical requirements, the reinforcement stripe 1 according to FIG. 1A will be incorporated within a masonry 26, there as a masonry reinforcement, wherein the stripe 1 is surrounded by masonry bricks and mortar arranged between the bricks.

(10) The reinforcement stripe 1 according to FIG. 1A defines a stripe plane 2, that is according to FIG. 1A corresponding to the plane of projection. The reinforcement stripe 1 comprises multiple stripe apertures 3, where according to FIG. 1A three complete stripe apertures 3 can be seen. Further stripe apertures 3 are indicated within FIG. 1A by showing a section of the aperture. Between the stripe apertures 3 a stripe land 4 is arranged respectively. Lateral to the stripe apertures 3 the stripe edge 5 is arranged, that margins the stripe 1 laterally. The stripe apertures 3 are almost rectangular, wherein the corners of the almost rectangular stripe apertures 3 are rounded. The stripe apertures 3 make, that the reinforcement stripe 1 is not only surrounded by the mortar, but also penetrated by the mortar in the range of the apertures 3. Thus clawing of the reinforcement element with it surrounding is improved.

(11) The stripe apertures 3 are arranged adjacent to each other along the longitudinal direction of the stripe 1. The stripe apertures 3 generate an material clearance within the reinforcement stripe 1, respectively. The stripe apertures 3 are margined by an aperture rim 6. The aperture rims 6 of the stripe apertures 3 shown in FIG. 1A have a wavelike characteristic—at least along sections. The wave peaks 7 (or at least at some of the wave peaks 7) of the aperture rims 6 generate rim serration members 8. The rim serration members 8 are bendable such, that they protrude out of the stripe plane 2. By bending the rim serration members 8 or of the stripe aperture rims 6, the reinforcement stripe 1 is appropriate for better clawing or toothing of the stripe with its surrounding (mortar, bricks).

(12) In the alternative to the wavelike wavy or characteristic of the aperture rims 6, a serrated, particularly saw-toothed, characteristic can be provided, which is not shown in FIGS. 1A to 4. Within a saw-toothed characteristic of the aperture rims the teeth (or at least some of the teeth) generate rim serration members 8, that can be bent out of the plane of the reinforcement stripe 1.

(13) According to FIG. 1A the rim serration members 8 at the stripe apertures 3 can be bent out in up or bottom direction with respect to the stripe plane 2 (as for example shown in the schematic illustration according to FIG. 1B). Bending out the rim serration members 8 can be achieved such, that stamping of the stripe apertures 3 is followed by a method step of bending. It can also be provided, that the method step of stamping comprises bending of the serration members 8.

(14) According to FIG. 1A on the reinforcement stripe 1 surface serration elements 9 can be found. The surface serration members 9 are arranged on the surfaces 10 of the reinforcement stripe 1, that means on the stripe lands 4 and/or on the stripe edges 5. The surface serration members 9 according to FIG. 1A are thus arranged adjacent and/or between the stripe apertures 3. The surface serration numbers 9 are generated such, that within the surface 10 of the stripe a labelling or lettering 11 is stamped in. By stamping and by the material replacement accompanied with the stamping, in the range of the lettering 11 material from the reinforcement stripe 1 emerges out of the surface 10 of the reinforcement stripe 1 and generates surface serration members 9. The lettering 11 thus at least partly emerges out of the surfaces 10 of the stripe 1 or out of the stripe plane 2, and thus enables additionally clawing of the reinforcement stripe 1 with its surrounding. Furthermore the lettering 11, particularly because of the embossing or stamping, can comprise notches and/or recesses or cavities within the material of the reinforcement stripe 1, that additionally contribute to clawing, and that are integral part of the surface serration members 9.

(15) It can be provide that sections 12 of the surface 10 of the reinforcement stripe 1 are roughened, so that a further optimization of clawing of the stripe 1 with its surrounding will achieved. Additionally (or in the alternative) cams 13 enhance the effect of clawing.

(16) The reinforcement stripe 1 according to FIG. 1A can be made from a metallic material or made from such material, that comprises a metal or a metal alloy. The reinforcement stripe 1 according to FIG. 1A is bendable, particularly within a direction, that is not within the stripe plane 2. In particular, stripe 1 is coilable to a coil of stripe in a way that is in principal known.

(17) Schematic illustrations of versions of a reinforcement stripe 1 according to FIG. 1A can it be found the FIGS. 1B and 1C. According to FIG. 1B it is provided, that the reinforcement stripe 1 comprises stripe apertures 3, the apertures 3 being arranged next to each other in two rows 24. More then two rows 24 can be allowed. According to FIG. 1B the stripe aperture 3 of the first row 24 are adjacent to the stripe apertures 3 of the second row 24 such, that in longitudinally direction of the stripe 1 mutual stripe lands 4 are generated between the stripe aperture 3, that means that the stripe lands 4 extend from the left stripe edge 5 to the right stripe edge 5 in continuous manner. Between the left and the right stripe edge 5 an intermediate stripe range 23 is arranged. The rows 24 with the stripe aperture 3 are positioned between the stripe edge 5 and the intermediate stripe range 23.

(18) A section of a reinforcement stripe 1 with two rows 24 of stripe apertures 3 is schematically shown in FIG. 1C, therein the stripe apertures 3 of the adjacent rows 24 show a position offset. The offset can be regular, that means constant over the length of the stripe 2, alternatively the offset can be unregular or varying. According to a further version, that is not shown in the figures, the stripe apertures can be arranged in the stripe plane in an arbitrary and/or unregular manner.

(19) According to the layout shown in the FIGS. 1B and 1C it will be achieved, that the length of the aperture rim per unit length of the reinforcement stripe will be enhanced, so that more rim serration members 8 per unit length of the reinforcement stripe can be arranged, so that clawing of the reinforcement element 1 with its surrounding is improved.

(20) A schematic side view of a masonry reinforcement 1 is shown in FIG. 1D. The reinforcement stripe 1 is from a dispenser roll, the dispenser roll being arranged on a dispenser axis 14, what is schematically indicated in FIG. 1D with dashed lines. In the reinforcement stripe 1 multiple stripe apertures are arranged adjacent to each other. The cutting plane of the sectional view according to FIG. 1D is centred or almost centred with respect to the stripe width and it is perpendicular to the stripe plane. As such FIG. 1D also shows the stripe lands 4 between the stripe apertures. At the aperture rims 6 of the stripe apertures 3 rim serration members are arranged, wherein the rim serration members are arranged such, that they protrude out of the plane of projection according to FIG. 1D. At the outer edges of the stripe edge regions (5) no serration members are provided.

(21) Moreover FIG. 1D shows surface serration members protruding out of the stripe plane. The surface serration members 9 can be made as cams 13 or as labelling/lettering 11, the labelling/lettering being stamped within the stripe.

(22) According to the schematic illustration of FIG. 2 a pair of rolls is shown, each of the rolls 19 being arranged on a mutual pivoting or dispenser axis 14 in rack 21. The rolls 19 can be constructed such, that the rim serration members 8 protruding out of the stripe plane 2 are orientated inwardly, that means into the direction of roll axis 14. Surface serration members 9 can be arranged on the inner side of the stripe (top side 15) and/or on the outer side of the stripe (bottom side 16, not shown in FIGS. 2 and 3). Transporting and/or storing of the coil stripe 1 can be done within a package or a housing 17. For simplified unrolling of the stripe 1, dispenser 18 for dispensing reinforcement stripes 1 can be used, the dispenser 18 is schematically shown in FIG. 3. In dispenser 18 according to FIG. 3 at least one dispenser roll is arranged, on that two reinforcement stripes 1 are arranged side by side. Preferably dispenser 18 can comprise two dispenser rolls 19, arranged side by side and coaxial according to an assembly that is schematically shown in FIG. 2. From a dispenser opening 20 of the dispenser 18 according to FIG. 3 two reinforcement stripes 1 (for example shown in FIG. 1) can be dispensed by operating the dispender rolls 19 together. Thus for a masonry 26 with propriate masonry width or masonry size two side by side arranged reinforcement stripes can be dispensed, so that reinforcement is improved and the handling of the reinforcement stripes 1 is simplified.

(23) The distance 21 between dispenser rolls 19 is variable according to FIG. 2, so that also the distance between the reinforcement stripes 1 is variable. Variation of the distance 21 of the dispenser rolls 19 or the reinforcement stripes 1 can be made such, that the reinforcement stripes 1 are arranged side by side fitting to the masonry size. By variation of the distance 21 of dispenser roll 19 the total width of the pair of reinforcement stripes becomes variable and fittable to the masonry size. Variation of distance 21 can for example be done by the user individually. It can also be the case, that a certain dispenser roll distance is chosen and preset by the manufacturer. According to a further embodiment of the dispenser 18 at least one further reinforcement stripe can be provided (not shown in FIGS. 2 and 3).

(24) Additionally it can be provided, that the reinforcement stripes 1 shown in FIGS. 2 and 3 schematically, are interconnected, particularly at multiple connection points. Thus the reinforcement stripes 1 can be dispensed from the dispenser simultaneously and can be unrolled in a parallel way.

(25) FIG. 4 shows a schematic illustration of a version of dispenser 18. Dispenser 18 comprises fixing and guidance mean 25. With the fixing and guidance means 25 dispenser 18 can be fixed on a masonry 26 and be guided on the edge of the masonry 26. The fixing and guiding means 25 is constructed with two clamps or braces, that are arranged at housing 17 of dispenser 18, in particular arranged pivot able. The braced can be arranged such, that they embrace or clasp the top edge of the masonry 26 that is to be provided with reinforcement elements 1. The braces cause a clamping effect, so that dispenser 18 can be locked on masonry 26. The reinforcement stripe 1 can be dispensed from the dispenser 18 without the user retaining the dispenser 18. According to FIG. 4 dispenser 18 also comprises separation means 27, wherein the reinforcement stripe 1 can be cut with the separation means 27. Separation means 27 is arranged at the housing 17 of the dispenser 18 in captive manner with a fastener. Separation means 27 is used, when the end of masonry 26 is reached and the length of the reinforcement stripe 1 has to be fitted to the length of the masonry 26.
