Abstract
The device comprises a delivery device (4-9) that delivers the additional part (2) into a delivery position (10) that is spaced apart from the book block spine (11a). The transfer device (13) comprises at least two holding elements (14a, b) that move in a reciprocating fashion and the cycles of which are phase-shifted relative to one another, wherein said holding elements move in different tracks (15a, b) that are offset relative to one another between the delivery position (10) and the book block spine (11a) and apply the delivered additional part (2) onto the book block spine (11a) after it was provided with glue. The holding elements (14a, b) carry out a reciprocating turning movement about a common axis (16), wherein the turning radius of at least one holding element is increased or decreased in the instant in which both holding elements (14a, b) pass one another.
