Abstract

The invention relates to a device for stapling to a material (1) at predetermined distances along a web formed by the material with the aid of a stapling cylinder (2), a counterpressure cylinder (3), a forming drum (4) and a horn (5) which extends around the periphery of the stapling cylinder between the forming drum and the counterpressure cylinder, wherein the stapling cylinder (2) coacts with a stapling fork (6) which is intended to cut a staple-forming section from wire-like material (10) in a region (B) between the stapling cylinder (2) and the forming drum (4) and to form therefrom a U-shaped staple which can be carried by the stapling cylinder (2) to a region (A) between the stapling cylinder (2) and the counterpressure cylinder (3) and there fastened to a material web (1) passing between the stapling cylinder (2) and the counterpressure cylinder (3). The stapling fork (6), at least in the region (B) between the stapling cylinder (2) and the forming drum (4), is intended to move along a first path section (11) and therewith cut and form a staple (7). The stapling fork (6), at least in the region (B) between the stapling cylinder (2) and the forming drum (4), is intended to be able to move along a second path section (12) in dependence on the occurrence of an activating signal and therewith prevent cutting of the wire-like material (10) and the formation of a U-shaped staple (7), or vice versa.
