(1) Increasing certain quantity of the hot-melt glue by glue meter, then make
some books to see if the spine has been improved on both sides.

make some books to see if the spine has been improved on both sides.
(3) If (1) or (2) can not improve the book spine, you have to do the adjustment
for the clamps. Slightly loosen the bottom lock nuts, then gradually tighten
the bottom screws of the clamps until there is no gap between the spine and
the nipping plate surface when you close the clamps. Make some books to
see if the spine has been improved on both sides.
