摘要： Device and method for controlling axial forces acting upon a moving web comprises first, second and third rotatable rollers. The third roller is between the first and second rollers and is movable in a circular path in the vertical plane between lower and upper positions in response to axial forces acting at any moment upon the web. To enable a simple manual installation of the web, the upper position of the third roller is at a sufficient vertical distance above the first and second rollers to form an open horizontal passage through which the web can pass freely between the first and second rollers and the above-situated third roller. Axial forces are controlled by biasing the third roller with a force which counters the motion of the third roller in the direction of the upper working position and which is less than the ultimate tensile strength of the web.

摘要： The disclosure relates to an apparatus for flexographic printing of a web of packaging material. The apparatus has an anilox roll which is rotary in an ink pan or chamber for picking up and transferring printing ink to an impression cylinder which is rotary adjacent the anilox roll and forms, together with a counter pressure cylinder rotary adjacent the impression cylinder, a nip through which the web is led for receiving printing ink from the impression cylinder. In order to prevent printing ink from drying and adhering to the anilox roll, the apparatus displays a spray- or shower device through which a cleaning fluid for the printing ink is applied on the circumferential surface of the anilox roll.

摘要： A printing system for printing a repeated pattern of esthetical and/or informative character on a substrate including a plurality of parallel webs is provided. The printing system comprises at least two overlapping non-impact printer units, each of which having a lateral elongation defining a maximum printing width, and a controller connected to each one of the printer units and configured to set an actual printing width extending between a start position and an end position of the lateral elongation, wherein the controller is configured to determine the actual printing width by receiving the lateral position of a non-printed area defined by the interface between two adjacent webs of the substrate and located laterally somewhere in the overlap between two printer units, such that the end position of a first printer unit and the start position of an overlapping printer unit is located within the non-printed area.
