[padg] RE: RE: RE: RE: Re: Co-libri cover material



After you slip one of the CoLibri pouches over the front cover and slip a second pouch over the back cover, you will have two excess flaps of polyethylene loose at the book's spine.  With the book resting on its back cover, put both flaps of excess through the gap where the weld is made, place the book spine (covered by the excess from the front pouch) against the metal edge of the welder and press to make the weld.  The excess from both the front and back pouches will be removed by the roller action.

We have recently purchased the CoLibri machine, especially to cover some
of the heavily used materials in the Archives' Reference Room. We've
avoided used it on a couple of volumes due to concerns similar to
Peter's.  I'm intrigued by the approach Susan describes here, but I
can't visualize how you weld the two pouches while they are on the book.
Can you help me out with a bit more explanation?

Many thanks --

A note on the process of using CoLibri rather than the composition of
the pouches.  We have developed a gentle procedure here at the
University of Iowa Libraries to place CoLibri covers on Special
Collections books.  We take two pouches, weld each to custom size before
they are placed on the book, then slip one on the front cover, one on
the back cover, and join the two with a welded seam at the (back cover)
spine.  It is necessary to open the book's covers only enough to slip
the sized pouch over each cover and dust jacket (if available).

The problem that I have with Colibri is that getting it on books is
often a brutal process that places unnatural stresses on the bindings,
especially at the joints. I would never use it for any special
collections materials... We don't use it here at Syracuse, but did have
a vendor stop by for a demo using some of our materials...
