May I suggest Bonnie Bates has a look at HDS home page.  It gives
details of the "Keeper" ultrasonic welding machine currently in use
at the National Library of Scotland.  I have found it to be a very
good piece of equipment and capable of producing quality welds.  It
has an infinite throat which is ideal for larger documents e.g.
newspapers and maps. Full details from
