A method and tool for forming convexities (3, 4) in a plate body (1), which plate body (1) comprises a main face (2) and a plurality of side edges. The plate body (1) is inserted between two tool halves (11, 12), which are brought together and interact to press a first set of convexities (3) in a first direction relative to the main face (2) of the plate body (1) and a second set of convexities (4) in a second, opposite direction relative to the main face (2) of the plate body (1). The convexities (3, 4) are formed along a straight line across the plate body (1) between two of the side edges thereof. The plate body (1) is secured so that the main face (2) thereof maintains its orientation, and each of the convexities (3) in the first set of convexities is pressed out by a length (1), measured from one side of the convexities (3) at a point (20) on the main face (2) of the plate body (1) along the convexity (3) to the second side of the convexity (3) at a point (21) on the main face (2) of the plate body (1), which is substantially equal to the corresponding length (1) by which each of the convexities (4) in the second set of convexities is pressed out.
Cette invention concerne un procédé et un outil servant à la formation de convexités (3, 4) dans un corps de type plaque (1) comportant une face principale (2) et une pluralité de bords latéraux. Le corps de type plaque (1) est inséré entre les deux moitiés (11, 12) d'un outil qui sont rapporchées et qui agissent comme une presse permettant la formation d'un premier ensemble de convexités (3) suivant une première direction relativement à la face principale (2) du corps de type plaque (1) et d'un second ensemble de convexités (4) suivant une seconde direction opposée, relativement à la face principale (2) du corps de type plaque (1), entre ses deux bords latéraux. Le corps de type plaque (1) est maintenu de façon à ce que sa face principale (2) conserve son orientation, et chacune des convexités (3) du premier ensemble de convexités est formée par pression sur une longueur (1) donnée, mesurée à partir d'un côté des convexités (3) au niveau d'un point (20) de la surface principale (2) du corps de type plaque (1) le long de la convexité jusqu'au second côté de la convexité (3) au niveau d'un point (21) de la face principale (2) du corps de type plaque (1), ladite longueur étant sensiblement égale à la longueur correspondante (1) sur laquelle chacune des convexités (4) du second ensemble de convexités est formée par pression.
