Doublebinding Unclaimed

Syncrom Binding and Finishing Systems presents the revolutionary new vorTEX doublebind machine that provides doublebinding solutions to offer layflat books at three times the pull-strength of perfect binding

Doublebinding is a technology which applies not only to the tips of paper, but also in-between the sheets. This results in unprecedented layflat quality in books.  With most binding methods, such as perfect binding, glue is always applied only to the very edges of the sheets of paper. This is a very small surface area for the glue to adhere to. In order to increase this surface area a little and increase the binding strength, the backs of the books are cut or nipped before the glue is applied. This results in a fairly thick layer of glue that creates a rigid spine that resists bending. Doublebinding overcomes this problem to the extent that it is the only glue binding method that compares with Smythe sewing.
