ABSTRACT:
A method of bookbinding. Sheets to be bound have at least an edge portion which is formed of thermoplastic. A thermoplastic portion of a spine is placed against these arranged edges. Urging the spine against these edges while causing relative reciprocation therebetween in the plane of the arranged edges effects thermal bonding of the sheets to the spine. In an alternative embodiment, plain paper is used with a thermoplastic film arranged between the edges of the sheets and the thermoplastic portion of the spine.
