Abstract
A machine for cutting a moving strip of material by means of a pair of cutting blades carried by their respective blade holders. The latter each are supported by a pair of eccentric shafts at their opposite ends for circular movement and are guided by two same guide bars for vertical slidal movement to ensure that the cutting blades are put into cutting engagement with the material at the same time and at the same cutting angle.
Claims2
A machine for cutting a moving strip of material into regular sizes by intermittently rotating two cutting blades at a speed synchronized with the speed at which the material to be cut is being fed, said machine comprising:
- a frame constructed for the material to be cut to pass through the center thereof,
- two opposed pairs of driving shafts laterally mounted through the side walls of said frame, one pair above the other,
- two opposed pairs of eccentric shafts eccentrically coupled to said driving shafts,
- an opposed pair of cutting blade holders each laterally supported by said pair of eccentric shafts at the opposite ends thereof so as to impart a substantially circular motion to said cutting blades as said driving shafts rotate,
- an opposed pair of cutting blades each fixedly mounted on said cutting blade holders with their cutting edges facing each other,
- means for driving said two pairs of driving shafts at the same time but in opposite directions, and
- a pair of vertical guide suspended from the top wall of said frame for longitudinal movement and loosely fitted in two vertical through holes formed in said cutting blade holders in alignment with said eccentric shafts, whereby putting said cutting blades into cutting engagement with the material at the same time and at the same cutting angle.
