Wiro/Double Loop Binding

Double Loop Binding

Wiro / Double Loop binding features a continuous double series of wire loops inserted in punched holes along the binding edge of a book. Ideal application for any publication that must lie flat, such as road atlases, calendars and teacher manuals. Compression problems, which can result in misaligned pages, are avoided with wiro. It allows back to back folding without damage.

Punching and Binding systems are available for your wiro / double loop requirements. With our other services we can produce your job from flat sheets to completed books.

The following points should be adhered to when planning your next job.

  1. Allow 8mm from spine to printing edge for punching.
  2. With celloglazed and laminated covers, jobs supplied collated should keep the front and back covers separate. We will collate the covers when binding.
  3. When folded sections are supplied, the spine must be perforated to allow the sections to remain flat along the spine for trimming the 4 edges. The preferred minimum spine margin is 10mm.
  4. When doing layouts for wire/double loop booklets, allow the minimum trim on the fore-edge, leaving any sheet waste in the spine of the section.
