Graphic Design & Printing Technology

This method involves using a special machine, to punch rectangular holes
along one edge of the printed material. After the sheets are punched, they are
positioned over the spread or expanded plastic teeth of the fastener. When
released, the plastic teeth are extended to the punched holes to bind the
publications. The same machine can be used to open the comb teeth so pages
can be removed or added.

Spiral binding:- It is similar to the plastic comb method, but does not allow
opening the binding for the addition or removal of pages. In this method,
smaller round holes are punched, then the wire is spiral fed through the booklet
using an automatic equipment. The method is used for many types of products
from small pocket notebooks to calendars, to books an inch or more in thickness.
Several variations of the spiral method are used, but all follow the same
principle.

Like most mechanical bindings, the spiral wire method allows a book to be
opened flat and remain that way. The spiral binding allows for the tearing out
of a page but not the insertion of sheets.
