Abstract

1,230,720. Cutting apparatus. POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRœSTUNGEN VEB. 17 Nov., 1969 No. 56145/69. Headings B4B and F2. A cutting machine for sheet material comprises a blade mounted in a carrier 17 which is raised and lowered by means of a fluid-pressure actuated piston-and-cylinder device 1, 2, the piston-rod 4 being connected by links 6, 8 to a bell-crank lever 9 which is connected to the blade carrier by a rod 13, the arrangement being such that when the blade carrier is in its lowest position, one arm of the lever 9 has moved to a position wherein it is substantially aligned with the rod. The links 6, 8 are provided in order to obtain a large angular movement of the bell crank lever 9 with a relatively short stroke of the piston rod 4. As shown in Fig. 1, the piston rod moves the link 6 through an angle 14 which is substantially half the angle 15 through which the bell-crank lever 9 is moved.
