Abstract

A reed and a method for producing a reed. The reed has a multiplicity of dents, which are arranged in a width direction, forming interspaces each having a dent spacing. Each dent has two opposite end sections, at which the dents are respectively connected to a carrier and to the immediately adjacent dent or dents by an adhesive connection. In at least one end section, the dent has a plurality of a spacer studs, which are preferably produced by embossing. The spacer studs form a depression on the one, first side and, on the opposite, second side, form a projection having a stud outer surface. The sum of all the stud outer surfaces of the spacer studs of a single end section of a dent has a proportion of at most 15% of the total end section surface on this second side.

First claim

The invention claimed is:

1. A reed ( 15 ), comprising:
a plurality of dents ( 16 ) that extend in a longitudinal direction (L) between a first end ( 17 ) and an opposite second end ( 18 ),
wherein individual ones of the plurality of dents ( 16 ) have end sections ( 19 ) adjoining the first end ( 17 ) and the second end ( 18 ) respectively and have a working section ( 20 ) between the end sections ( 19 ),
whereas individual ones of the plurality of dents ( 16 ) have a first dent outer surface (A 1 ) extending in a first plane (E 1 ) in the working section ( 20 ) and have a second dent outer surface (A 2 ) extending in a second plane (E 2 ) in the working section ( 20 ), wherein the two planes (E 1 , E 2 ) are orientated parallel to each other,
wherein in at least one end section ( 19 ) of at least one of the plurality of dents ( 16 ) multiple spacer studs ( 30 ) are present that are deepened at a first side (S 1 ) compared with the first plane (E 1 ) respectively and that are raised at a second side (S 2 ) compared with the second plane (E 2 ), wherein a percentage of a sum of the stud outer surface areas (F) of all of the multiple spacer studs ( 30 ) at their second side is at most 15% of a total end section surface area of a common end section ( 19 ) at the second side, and an adhesive bond is created between adjacent end sections ( 19 ) of individual ones of the plurality of dents ( 16 ).

2. The reed according to claim 1 , wherein the multiple spacer studs each have an inner surface area (I) at the respective first sides (S 1 ) thereof and a percentage of a sum of the stud inner surface areas (I) of all of the multiple spacer studs ( 30 ) is at most 15% of the total end section surface area at the first side.

3. The reed according to claim 1 , wherein individual ones of the multiple spacer studs ( 30 ) are free of through-holes.

4. The reed according to claim 1 , wherein individual ones of the end sections ( 19 ) of the plurality of dents are free of through-holes.

5. The reed according to claim 1 , wherein the plurality of dents comprises two outer dents ( 16 r ) and multiple intermediate dents ( 16 m ), wherein at least all of the intermediate dents ( 16 m ) comprise spacer studs ( 30 ) in one or both end sections ( 19 ).

6. The reed according to claim 1 , wherein all of the plurality of dents ( 16 ) comprise spacer studs ( 30 ) in one or both end sections ( 19 ).

7. The reed according to claim 1 , wherein each of the multiple spacer studs ( 30 ) has a central stud portion ( 31 ).

8. The reed according to claim 7 , wherein each of the multiple spacer studs ( 30 ) has an outer stud portion ( 32 ) that surrounds the central stud portion ( 31 ).

9. The reed according to claim 7 , wherein each of the multiple spacer studs ( 30 ) has an outer stud portion ( 32 ) that surrounds the central stud portion ( 31 ) and the central stud portion ( 31 ) is conical or cylindrical or ball shaped and/or the outer stud portion ( 32 ) is conical.

10. The reed according to claim 1 , wherein individual ones of the multiple spacer studs ( 30 ) of directly adjacent end sections ( 19 ) of two of the plurality of dents ( 16 ) are aligned with respect to each other.

11. The reed according to claim 1 , wherein individual ones of the multiple spacer studs ( 30 ) have a height H compared with the second plane (E 2 ) that corresponds to the distance between the first plane (E 1 ) and the second plane (E 2 ).

12. The reed according to claim 1 , wherein individual ones of the multiple spacer studs ( 30 ) have a diameter (D) and a height (H) from the second plane (E 2 ), wherein the diameter (D) is 5 to 10 times as large as the height (H).

13. The reed according to claim 1 , wherein individual ones of the plurality of dents ( 16 ) are connected via their two end sections ( 19 ) to a carrier ( 27 ) by an adhesive bond, wherein two directly adjacent dents ( 16 ) of the plurality of dents respectively either do not abut against each other or spacer studs ( 30 ) of one of the two directly adjacent dents ( 16 ) abut with the second side (S 2 ) of the respective other directly adjacent dent ( 16 ).

14. A method for producing a reed ( 15 ) according to claim 1 comprising the following steps:
Embossing at least one of the plurality of dents ( 16 ) for creating the multiple spacer studs ( 30 ) in at least one end section ( 19 ) of the at least one dent ( 16 ) in an embossment station ( 40 ),
Positioning individual ones of the plurality of dents ( 16 ) with a defined distance with respect to each other in an assembly station ( 43 ),
Creating an adhesive bond between individual ones of the adjacent end sections ( 19 ) of the plurality of dents ( 16 ).
