A booklet making machine comprises a pair of motor driven rollers ( 14 ), between which sheets forming a booklet, after being stapled together, are intended to be entered for folding and feeding for delivery. Each roller comprises a rigid jacket ( 20 ) which is attached to a rotation shaft extending in the longitudinal direction of the roller by elastic means ( 24 ) disposed between the jacket and the rotation shaft for relative displacement of shaft and jacket in radial direction while overcoming a spring force. |
