Abstract
An apparatus which is used to impart a specific configuration to substantially flat elongated strips of deformable wire binding elements for stacks of overlapping perforated sheets or the like has a transporting unit serving to advance binding elements lengthwise in a predetermined direction along an elongated path, a unit which converts strips in a first portion of the path into transversely curved intermediate products having a substantially C-shaped cross-sectional outline and a shape which at least approximates the predetermined configuration, and an altering unit which serves to deform--in a second portion of the path downstream of the first portion--at least those intermediate products the shape of which departs from the predetermined configuration. The altering unit can comprise a unit which serves to stretch at least some of the intermediate products in the predetermined direction and/or a unit which serves to bend at least some of the intermediate products at least substantially transversely of the predetermined direction.
