Title (EN) METHOD AND MACHINE FOR CUTTING SHEET MATERIAL
(FR) METHODE ET MACHINE DE COUPE D"UN MATERIAU EN FEUILLES
Abstract: front page image
(EN)A method for quickly cutting rigid polyurethane foam laminate, especially metal faced laminate, while the laminate is continuously transported on a conveyor, consists of moving circular saws, am arranged in fixed disposition alternately above and below the laminate, towards and away from the laminate in a line perpendicular to the laminate. The saw blades collectively extend across the width of the laminate. Alternatively the blades are moved with a giratory motion to increase the effective cutting width of each blade enabling the blade diameter to be reduced. Saws (11 and 12) are two of three saws extending across the width of laminate (14) supported on a frame (15) mounted in guides (16) on a carriage (17) movable in synchronism with advancing laminate (14). The saw blades (11" and 12") are moved alternately into cutting engagement with the laminate by displacement of frame (15) relatively to carriage (17).
(FR)Une methode pour couper rapidement un lamine rigide de polyurethane mousse, specialement un lamine a faces metalliques, pendant que celui-ci est transporte sur une bande transporteuse, consiste a mouvoir des scies circulaires placees selon une disposition fixe alternativement au-dessus et en-dessous du lamine, se rapprochant et s"eloignant du lamine perpendiculairement a ce dernier L"ensemble des lames des scies s"etends sur toute la largeur du lamine alternativement, les lames decrivent un mouvement giratoire de facon a augmenter la largeur de coupe effective de chaque lame permettant ainsi une diminution des diametres des lames. Les scies (11) et (12) sont deux des trois scies qui s"etendent en travers de la largeur du lamine (14) supporte par un cadre monte sur des guides (16) d"un charriot (17) dont le deplacement est synchronise avec l"avance du lamine (14). Les lames de scies (11") et (12") se deplacent alternativement pour couper le lamine par deplacement du cadre (15) par rapport au charriot (17).
