Abstract:
An apparatus for cutting a web material fed continuously along a path through said apparatus, the apparatus comprising:a rotating cutting cylinder; and an opposing member; said cutting cylinder and said opposing member being arranged on opposite sides of said path, said cutting cylinder having a length and a plurality of blade segments distributed along the length of said cutting cylinder and connected to a plurality of actuators so as to produce selective extension and retraction of said blade segments with respect to said cutting cylinder; wherein each blade segment is supported by a pivoting part hinged about a hinge axis, the extension and retraction of said blade segments being produced by a pivoting movement of said pivoting part about said hinge axis; and a stop engageable with each pivoting part to absorb at least a portion of a stress exerted on the corresponding blade segment during cutting of the material, each pivoting part being disengaged from said stop in a non-cutting position of the corresponding blade segment; wherein said cutting cylinder defines a circumference, wherein said stop is on a block attached to an outer circumferential surface of the cutting cylinder, said block carrying a pivot pin for the pivoting part of the corresponding blade segment.
