An apparatus for binding groups of loose perforated sheets for albums, copy-books, calendars and the like, with a series of interconnected C-shaped binders formed directly from a wire feeding reel. Selecting, prefixing and numbering of loops to be cut and inserted into the sheets to be bound are automatically achieved by electronic control devices. Coupling between binder elements and sheets is statically accomplished by manually placing the sheets to be bound in a given position and by operating a press, for example, by means of a foot control lever or of the same group of sheets. The apparatus is designed also for inserting in one single group of perforated sheets two spaced multiple loop segments whose mutual distance and number of loops can be previously adjusted. |
