ABSTRACT:
A cheekstrip having an upper part and lower part fits into a knife box assembly that is intalled in the rotary cutting cylinder of the folder used on a roll fed printing press. The upper part is made from a hard material and is connected to the lower part, which is made from a soft material such as open-cell sponge rubber. A knife is inserted between flat surfaces of two cheekstrips. The soft material applies correct pressure to the upper part, which contacts the paper against an adjacent member and clamps it securely, to enable the knife to make a quiet, consistent, distortion-free severance.
