I have used white glue to try to rebind some of my books and it does
work very well on cloth and paper... but I am dead set on using the Cordura
nylon as the outer layer on the bellows. I would have my doubts that the
white glue would adhere permanently to these materials... I would have more
faith in contact cement ... .. It would be nice if I could find something
that would allow a little time to position the two assembles, and adheres to
these materials, and is sprayable....
I imagine in the old days they would have used animal hide glue or
fish glue and called it a day. That was about their only option.......I
will take your suggestion though and give what ever glue I find a test .
