Claim:
Arrangement for the precise positional joining of a first material web ( 1 ), comprising sections of a section length (A 1 ), each including an element (B), and a second material web ( 2 ), having marks ( 2 a ) disposed at a predetermined distance (A 2 ) from one another, which, except for a possible difference (D), corresponds to the section length (A 1 ), said arrangement comprising a first device ( 3 ), by which the two material webs ( 1 , 2 ) are joined, a transport device ( 5 ), by which the two material webs ( 1 , 2 ) are advanced section-wise by the predetermined distance (A 2 ) and a second device ( 4 ), by which an element (B) is applied to the first material web ( 1 ) whenever, after the advancement of the two material webs ( 1 , 2 ) by a section, the length of the first material web ( 1 ) between the first device ( 3 ) and the second device ( 4 ) corresponds to a multiple of the section length (A 1 ) plus possibly an offset which is adjustable by an offset arrangement ( 6 , 6 a ), and a sensor ( 7 ) by which the difference (D) can be determined and the offset is adjusted by the offset arrangement ( 6 , 6 a ) dependent on the difference (D).
