ABSTRACT:
A system for the perfect binding of a book block (14) within a soft paper cover is disclosed in which the center portion (18) of the cover is sized relative to the thickness of the book to be bound. An activatable adhesive is applied to the inner surface of the center portion of the cover. The book block is inserted into the cover such that the spine (S) of the book block is generally in register with the adhesive. The cover is forcibly compressed onto the book block by pressing members (60a, 60b). An ultrasonic horn (66) is brought into forcible working engagement with the outer surface of the center portion of the cover and is rendered resonant so as to transmit ultrasonic energy to the adhesive sufficient to melt the adhesive and to force the adhesive into the edges of the pages of the book block along the spine and to force the pages of the book block into the adhesive along the center portion of the cove such that upon the cessation of the ultrasonic energy the adhesive hardens substantially instantaneously thus binding the cover to the book block. A method of binding a book is also disclosed.
