Punching Patterns

Different elements require different punch patterns, some requiring bigger punches than others, which consequently lead to larger margins for paper removal to be necessary. The shape and size of punch holes both factor into deciding the margins of a particular project.

In addition, the number of holes per inch in a chosen pattern can affect the top to bottom dimensions of a book.  Some patterns do not allow for removal of a punching pin, leading to a necessary adjustment in book size.  Not adjusting when necessary would lead to the pin punching out a partial hole at the top or bottom of the book.


Plastic Spiral Binding

This type of binding coil is formed in-house at Wrap-Ups to the exact size specific to the book thickness.  This coil is formed inline and dropped automatically into two binding machines for a total throughput of up to 1,000 books per hour.  Each coil after insertion is crimped and bent on each end to avoid any reversal, or backing-out, of book.

One of the best features about plastic spiral binding is it will always maintain its original shape, even when crushed.  The crimped edges make the products safer and plastic spiral binding is therefore commonly used in children’s books, cookbooks, and street guides.  Its durability also makes plastic the preferred material for products that will be used frequently.


Wire-O/Twin Loop Binding

Both wire names have been trademarked by their respective manufacturers to develop brand recognition, but there is no true difference in the quality of either in comparison to the other.  Wrap-Ups commonly refers to this style of wire as Wire-O for simplicity’s sake.

The manufacturer sends this wire pre-formed on a spool.  It will be ordered by Wrap-Ups at the color and size chosen for each job.  Machines insert and close the wires.

This is considered by some to be the “high end” style of binding due to its cleaner presentation of binding.  It also creates a direct parallel alignment from the left page to the right page with respect to cross overs.
