The invention is a creasing device for creasing paper or card before it is folded. The device consists of a drum-shaped male component (2) featuring grooves (8, 10, 12) of various widths and depths to hold rubber O-rings (24, 26, 28). A female component (4) is almost identical to the male component (2) but has receiving grooves (14, 16, 18) that are slightly wider and deeper. When fixed to top and bottom shafts with one O-ring (24, 26, 28) in a groove (8, 10, 12) on the male component (2) aligned with a receiving groove (14, 16, 18) of the female component (4), a sheet of paper fed between the drums will be creased by the pressure of the O-ring (24, 26, 28) forcing the paper into the receiving groove (14, 16, 18). The invention allows the device to be quickly and easily set up to form creases of various widths and depths, while the resilient O-rings minimize damage to the paper. |
