Abstract
Described is a device and a procedure to twist a coil into perforations that are provided in the margin sections of flat components, sheets of paper in particular, with a drive that causes the rotation and axial in-feed of the coil, corresponding to the inclination of its helix shape. With a stopping device the coil is inhibited from moving further and a release brings the coil out of contact with the stopping device and into contact with the drive.
