Method for the production of a laminate material for hook and loop closures

1. A method for the production of a laminate material for hook and loop closures, comprising the following steps:

laminating a textile material onto a carrier film via an adhesive,

continuously passing the laminate material to a brush arrangement without winding the laminate material onto a take-up roll;

brushing the textile material after said step of laminating;

wherein the adhesive is applied to the carrier film in a pattern that has fields having adhesive areas and regions that are free of adhesive, and having field frames comprising an adhesive film applied over an entire area, and

forming separate pieces from the laminate material, wherein the field frames are disposed in such a manner that the textile material and the carrier film have a complete surrounding glue connection at edges of the pieces obtained from the laminate material, said pieces forming female parts of hook and loop closures,

wherein the brushing step is accomplished by means of at least one brush roller, wherein a surface of the brush roller moves at a positive or negative relative speed with regard to a speed of the laminate material that passes underneath the brush roller

wherein by means of the brushing step the textile material in the non-glued regions of the laminate material are affected and deflected resulting in an improvement of the hook and loop properties of the laminate material, whereby some yarns that comprise textile material are split into fibers.

2. A method according to claim 1 , wherein the carrier film, adhesive and the textile material pass through a pair of rollers in which the carrier film is pressed together with the textile material.

3. A method according to claim 1 , wherein the adhesive is applied to the carrier film using a rotary printing method.

4. A method according to claim 1 , wherein the adhesive is applied to the carrier film, in the fields, in one or more of the following patterns: dots, parallel stripes, intersecting stripes, or a cell-shaped structure.

5. A method according to claim 1 , wherein reference marks that are visible or can be seen only under UV light are imprinted on the carrier film to mark the fields.

6. A method according to claim 1 , wherein the textile material has a weight per area unit between 5 g/m 2 and 60 g/m 2 .

7. The method according to claim 1 , wherein the proportion of the adhesive-covered area within in the fields amount to 40% to 60%.

8. A method according to claim 1 , wherein said step of brushing is accomplished with at least one brush having bristles made of metal or plastic, in one or more work steps.

9. A method according to claim 8 , wherein said at least one brush has bristles that are disposed at a slant on the brush surface, or are bent.

10. A method as in claim 8 , wherein the brushing step further comprises using at least one fixed brush.

11. The method as in claim 10 , wherein said at least one brush is pivoted at an angle offset relative to a direction of movement of the textile material.

12. The method as in claim 1 , wherein said step of brushing causes said textile material to become more voluminous.

13. A method according to claim 2 , wherein said step of brushing is accomplished with at least one brush having bristles made of metal or plastic, in one or more work steps.

14. A method according to claim 13 , wherein said at least one brush has bristles that are disposed at a slant on the brush surface, or are bent.

15. A method as in claim 13 , wherein the brushing step further comprises using at least one fixed brush.
