Abstract: A cutter blade is provided with resilient means having sections for engaging the web adjacent the cut being made and these sections exert oppositely directed tensile forces on the web on the opposite sides of the cut to assist in separating the cut edges being formed. The resilient means may also cushion the blade against vibration which would cause the blade edge to chip or dent. The blade may be made of a ceramic material encapsulated in a resilient sheath with only the cutting edge of the blade exposed for cutting the web.

Abstract: A support structure for supporting a plurality of ceramic drainage bar elements in end-to-end relation for substantially straight-line contact with the moving forming carrier of a Fourdrinier papermaking machine and the like, wherein the ceramic drainage elements have identical generally tubular configurations and are fixedly supported by mounting saddles on a support beam to maintain the elements in relatively rigid axial alignment. The support beam is mounted for rotation about an axis coincident with the longitudinal axis of the aligned drainage elements to control the suction acting on the forming carrier.
