A paper folding assembly (15) with a plurality of rotatable rollers (18) including a cutting cylinder (60) with a cutting cylinder body (76) mounted for rotation with a rotary drive shaft (66) and having cutting members (84A, 84B) for cutting a paper ribbon (19) into individual paper sheets (24) and folding members (82A, 82B) for creasing the individual sheets (24) into a rotatable jaw cylinder (50) to create a lap (20) between opposed edges (22, 23), a cutting cylinder lap adjustment apparatus (70) with an end plate (62) secured to the folding members (82A, 82B) and mounted to the rotary drive shaft (66) adjacent an end (72) of the cutting cylinder body (76), a plurality of cutting members (84A, 84B) secured to the cutting cylinder body (76) which is mounted for rotary movement around the rotary drive shaft (66) and an adjusting member (90) connected to the cutting cylinder body (76) to move the cutting members (84A, 84B) at different selected angular positions relative to the rotary drive shaft (66) to change the lap (20) without adjusting the synchronized timing between the cutting cylinder body (76) and the jaw cylinder (50).
