摘要：<p>Apparatus for applying constant pressure to a plurality of anvil rollers (12) for crush-scoring used in combination with crush-scoring cylinders (68) having protrusions (88) extending from the surface thereof. Each anvil roller (12) is supported in a substantially frictionless manner and the constant pressure is supplied by a flexible diaphragm (60) acting on a plunger (56) which can move substantially without friction in a pneumatic cylinder (52).</p>
