Evaluation of binding strength depending on the adhesive binding methods

Abstract

A book with a personal value is worth remembering since it represents specific interests of an individual - author of the book. Therefore the original is the first issue of a book which is always bound manually. Due to cost-effectiveness, adhesive binding is most commonly used in author’s edition in paperback and hardback. Adhesive binding methods differ only if a paper leaf is a binding unit in adhesive binding form. The subject of the research is the quality of book block binding for two binding methods with/without mull fabric. The assumption is that double-fan adhesive binding method shows an extraordinary binding quality as compared to the rough spine method. For the needs of this research book block parameters remained unaltered: paper type, size and book volume. The results related to strength were obtained by using an experimental method of tensile strength for individual paper leaves. The rating of book block quality was conducted in accordance with FOGRA Nr.71006 guidelines for page pull-test. Furthermore, strength results for both methods were compared in order to evaluate the importance of changing the quality of adhesive binding. Statistical method ANOVA analysis of variance and Fisher’s F-test were used to evaluate the quality of book block binding.
