ABSTRACT:
An apparatus is provided for producing coils in the course of a process for the production of binding coils which are to be introduced directly into a row of holes in a pack of sheets. The apparatus has a winding spindle which is surrounded by the coil produced, from which the coil lifts when the front end of the coil is stopped, the winding spindle being driven continuously. A cutting device, for example in the form of scissors is provided for cutting the coil. A device for stopping the front end of the coil periodically is provided between the winding spindle and the cutting device, the stopping device being arranged to operate with a timing correlated with the operation of the cutting device.
