Abstract

Perfect bound book is certainly the most used
type of book product on the market. The quality
of this kind of product can be identified with
the binding strength of the book block. There is
only one standardized method for book block
strength determination and it refers to the static
testing of interrupted tensile force required to
separate precisely defined leaves within a test
sample. In this paper, six groups of book block
were investigated, different with regard to
paper composition, i.e. the share of primary and
recycled fibres and thus the content of ash and
calcium carbonate. Furthermore, two binding
techniques were used, but all other parameters
– volume, format, pressure and drying time,
temperature and humidity, were always same and
strictly controlled. Based on obtained results,
evaluation of finished product quality was
performed, depending on paper properties, as well
as evaluation of the used binding techniques. By
calculating coefficients of variation, a binding
technique that allows a more uniform application
and guarantees reliability and repeatability of the
quality results was chosen, regardless the paper
composition.
