A paper binding apparatus includes a pair of guides between which a paper bundle connected body formed by applying an adhesive tape to edge portions of sheets that are overlapped in a thickness direction, is moved in a reference direction while pinching the paper bundle connected body in the thickness direction, a guide plate on one side of the paper bundle connected body and downstream of the pair of guides, the guide plate having at least one guide surface that causes the paper bundle connected body guided thereby to be bent, and a driving roller configure to rotate in a first direction to move the paper bundle connected body and to cause a leading edge of the paper bundle connected body to be guided and bent by the at least one guide surface and the edge portions of the sheets to be shifted from each other in the reference direction.

A method for applying portions of a backlining material to a back of a book block includes transporting the book block in a conveying direction in a book production line. The back of the book block is provided with an adhesive, wherein the book block is initially provided with the adhesive over an entire back length of the book block in a single application process. Then, the portions of the backlining material are applied in succession to the back of the book block, wherein at least a first portion of the backlining material is applied by a first conveying device and subsequently at least a second portion of the backlining material is applied by a second conveying device to the back of the book block such that at least one of the portions overlaps another one of the portions.
