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.
L'invention concerne un dispositif de plissage servant à plisser du papier ou du carton avant de le plier. Ce dispositif est muni d'un composant mâle (2) sous forme de tambour comprenant des orifices (8, 10, 12) de diverses largeurs et profondeurs destinés à recevoir des joints toriques en caoutchouc (24, 26, 28). Un composant femelle (4), presque identique au composant mâle (2), possède des orifices de réception (14, 16, 18) sensiblement plus larges et plus profonds. Une feuille de papier, fixée aux arbres supérieur et inférieur à l'aide d'un joint torique (24, 26, 28) placé dans un orifice (8, 10, 12) du composant mâle (2) aligné avec un orifice de réception (14, 16, 18) du composant femelle (4), et insérée entre les tambours, est plissée par la pression du joint torique (24, 26, 28) poussant le papier dans l'orifice de réception (14, 16, 18). Le dispositif peut être réglé rapidement et facilement pour former des plissages de diverses largeurs et profondeurs, les joints toriques élastiques endommageant au minimum le papier.
