A Tip for Better Cover Gluing on Perfect Binding Machines

[fa icon="calendar"] Fri, Jun 17, 2016 / by Andre Palko

Today we’re going to show you a solution to a common problem that affects operators of perfect binding lines. The problem happens after the cover is glued and applied to the book block.

Hinge scores will sometimes help with the problem but not always. That’s because the weight of the cover opening on its own is usually not enough to break the score, even if it’s very strong.

One easy workaround to the problem comes to us from Rodrigo Castellanos of Technifold Mexico who also runs several perfect binding lines in his book bindery.

His perfect binder operators use a cardboard edge protector that is commonly used in shipping. In the video we show how to position it to support the covers and thus prevent the problem.
