    摘要： A method for synchronized positioning of a web for manufacturing products. The method includes feeding the web into a production apparatus at a first speed; processing in the production apparatus, with the web being fed forward at a second speed; and detection of each synchronization mark for positioning the respective motif in a predetermined position on each product. The method includes the following steps: generation of a reading of the actual value of a virtual master function upon the detection, which includes a cyclic clock where the number of cycles per product includes an integer; comparison between the actual value and the expected value of the virtual master function; and stretching of the web in response to any deviation between the actual value and the expected value, with the aim of minimizing the deviation.

    摘要： A wrinkle-reduction system includes two media guiding rollers located in proximity to first and second edges of a media, each media guiding roller having a corresponding roller axis and having one or more grooves formed around its exterior surface. The media travels along a transport path past the media-guiding rollers with a first side of the media facing the exterior surface of the web-guiding rollers. Air sources provide an air flow into the grooves in the media-guiding rollers, the air flow being directed between the first side of the media and the exterior surface of the media-guiding rollers thereby producing a Bernoulli force to draw the media toward the media-guiding rollers. The first roller axis is not parallel to the second roller axis such that when the air sources are activated the media guiding rollers impart a lateral stretching force to the media in the cross-track direction.

    摘要： A coreless roll of paper is formed by winding a web of paper around an elongated mandrel to form a roll of convolutely wound paper. The mandrel is formed from flexible and elastic material, and after the roll is wound, the mandrel is pulled longitudinally and withdrawn from the roll of paper to form a coreless roll.Alternatively, the mandrel can be pressurized to expand the mandrel radially before or during the winding of the web around the mandrel. After the roll is wound, the pressure in the mandrel is relieved so that the mandrel contracts radially, and the mandrel is withdrawn from the roll.A novel clasp is used to grasp and extract a tubular mandrel from the roll. The clasp includes a rigid shaft which is adapted to be inserted into a tubular mandrel. A plurality of clamping blocks are spaced radially outwardly from the shaft and are spaced circumferentially around the shaft. A plurality of actuators are engageable with the clamping blocks to move the clamping blocks radially inwardly toward the shaft whereby a mandrel can be clamped between the clamping blocks and the shaft.

    摘要： Method and apparatuses for measuring and regulating the strain of a material web is disclosed. A material web is passed through a first and second non-slip roller pair. The first and second roller pair form a predefined span. In some embodiments, the angular positions of the first and second roller pair are monitored, and the phase angle between the roller pairs is calculated. The phase angle is directly related to the level of strain in the web, and the velocity of the web is controlled to maintain a phase angle which corresponds with the desired strain level. This maintains a constant strain level in the predefined span. In one embodiment, the strain entering a non-slip roll pair is controlled to be zero. The roll pair then introduces a predefined strain to the span entering subsequent processes.
