  • Publication number: 20230381992
    Abstract: 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.

  • Publication number: 20110219975
    Abstract: A method of colour setting in a rotary printing press, in which a composition of an ink is adjusted until colour specifications of a printed product, that is formed by a substrate with the ink printed thereon, match given target colour specifications, including the steps of measuring (S1) a volume carrying capacity of an inking roller that will be used in the printing press for printing with the ink, measuring (S2) a spectral opacity of the substrate, measuring (S3) a spectral absorptivity of the ink when it is in a liquid state in the printing press; and entering the measured volume carrying capacity, spectral opacity and spectral absorptivity into a mathematical model (S4) for predicting the colour specifications of the printed product.
