ABSTRACT:
An apparatus with a cutting device for cutting-off pieces of a wire comb binding material for binding packs of sheets with marginal perforation. The pieces to be cut-off from the material shall have an entire number of teeth. The apparatus has a guide and a conveying wheel for the material. A brake or a catch provides for the pitch-correct cutting of the material. An adjusting device for adjusting the conveying length is provided in the drive connection to the conveying wheel. For this purpose a sector gear wheel comprises partial sector gear wheels. These are rotatable and capable of being fixed with respect to one another. Alternatively, an eccent arrangement may be used for adjusting the conveying length. The radial eccenter distance of the arrangement is adjustable. A chain driven thereby is itself driving a chain wheel, which on its turn drives a catch wheel for driving the conveying wheel.
