Abstract:
1. A die cutting machine to generate a cutting force to be applied to a cutting die for cutting a material, said die cutting machine comprising a body, a deck surface supported by said body upon which the cutting die is laid, a press plate that is movable in a direction towards said deck surface to apply the cutting force against the cutting die, a press plate cover located above and movable with said press plate, a rotatable lever arm extending through said press plate cover such that a rotation of said lever arm relative to said deck surface causes a corresponding linear movement of said press plate cover and said press plate, a swing hook that is rotatable from an unlatched position at which to release said lever arm to a latched position at which to engage said lever arm and hold said lever arm against said deck surface, a rotatable locking knob that is connected to said swing hook such that a rotation of said locking knob causes a corresponding rotation of said swing hook between the unlatched and latched positions, a shaft extending between said rotatable locking knob and said swing hook such that a rotation of said locking knob causes a rotation of said shaft and a corresponding rotation of said swing hook between the unlatched and latched positions, a mounting collar extending from said locking knob and surrounding said shaft so as to cause said shaft to rotate in response to a rotation of said locking knob, a tab projecting from said mounting collar, and a swing hook retainer for engaging the tab of said mounting collar to prevent a rotation of said shaft and a corresponding rotation of said swing hook from the latched position to the unlatched position.
