ABSTRACT:
In a device (1, 51) for applying an adhesive to the spine (2a) or to areas (2b) of the lateral faces adjacent thereto of an inner book (2) having a projecting portion and conveyed past in a transport system (3), comprising at least one rotating application roller (53a,b) or application disc (5) which picks up the adhesive from a reservoir (4, 52) and transfers same to the inner book (2) by rolling-off, the device having a doctor blade (7, 54a,b) adjustable with regard to its distance from the application roller (5, 53a,b) for regulating the application thickness of the adhesive and having an actuating device (8, 9, 57, 59) for the controlled movement of the doctor blade (7, 54a,b) between an application and a zero-application position, it is provided that the actuating device includes at least one single-acting contraction hose (24a,b,56a,b) controllable via compressed air (P) and acting as a pull actuator.
