Publication number: 20230381992Abstract: A method of cutting a running web, including the steps of: training the web over a smooth peripheral surface of an anvil drum; rotating a blade that extends in an axial direction of the anvil drum about an axis of rotation that is parallel to the axis of the anvil drum; retaining the blade in a retracted position in which a cutting edge of the blade is spaced apart from the web on the anvil drum, the blade being retained against a biasing force of a pre-loading mechanism that biases the blade in a direction towards the axis of the anvil drum; and releasing the blade at a time calculated to assure that the blade will hit the web at a time when the blade passes through a plane that contains the axis of the anvil drum and the axis of rotation.Type: ApplicationFiled: August 10, 2021Publication date: November 30, 2023Inventors: Gordon Whitelaw, Thomas Haecker
