Arrangement for applying an adhesive onto outer surfaces of an inner book to be inset into a book cover by means of an inset machine

摘要

An arrangement for applying an adhesive to outer surfaces of an inner book to be inset into a book cover by an insetting machine, moving inner books on saddle plates of a circulating conveyor vertically upwardly. The arrangement has an adhesive applying device with two application rollers positioned opposite one another in an area of adhesive application. The two application rollers each roll along one of the outer surfaces of the inner book to apply an adhesive onto the outer surfaces of the inner book as the inner book is moved upwardly on a saddle plate. The two application rollers each have a recess forming a shoulder parallel to an axis of rotation of the application rollers, wherein the recesses apply the adhesive to grooves of the inner book and wherein a rotary position of the recesses is adjustable according to a position of a given groove shape of the inner book passing through the area of adhesive application. The two application rollers and the conveyor of the saddle plates are coupled by a drive connection so as to be driven in a cycle-synchronized way. The drive connection has a pulling element gear unit for a continuous adjustment of a relative position between the saddle plates and the rotary position of the application rollers.
