    摘要： Unwinder of a thin ply product wound on a roll, comprising —a first roll-holder assembly equipped with a first unwinding rod for a respective roll, on which the roll is adapted to be supported, and which has an axis of rotation transversal to the direction of movement of the ply unwound from the roll, —a second roll-holder assembly equipped with a second unwinding rod of a respective roll, on which the roll is adapted to be supported, said second rod being parallel to said first unwinding rod of the first roll-holder assembly, said second roll-holder assembly facing said first roll-holder assembly in an unwinding zone, —a ply splicing assembly placed above said first and second facing roll-holder assemblies, —a ply accumulation unit to allow automatic switching between a roll being unwound in one said roll-holder assembly and a spare roll provided in the other roll-holder assembly, —a system for the lateral movement of each of said unwinding rods with respect to said unwinding zone, from said unwinding zone to a loading zone wherein said rolls are outside said winding zone to facilitate loading the rolls into the respective roll-holder assemblies, wherein said splicing assembly can be moved from a working position above the two said roll-holder assemblies in said unwinding zone, to a working position above an extracted roll assembly in the loading zone, to allow preparation for splicing of the leading edge of the ply wound on the spare roll.

    摘要： A control system and method for a sheet registration device including a general unit which determines desired contact point velocities for moving a sheet along a reference trajectory. The contact point velocity determination is independent of the sheet registration device. A specific unit is operably connected to the general unit. The specific unit determines registration device specific operating parameters for controlling registration device actuators to move the sheet along the reference trajectory.

    摘要： A photosensitive chip, including: at least one set of photosensors substantially aligned in a Y direction; and a layer of non-transmissive material including a plurality of openings. Each opening in the plurality of openings includes a respective center line and overlaps only a portion of a respective photosensor so that only the portion of the respective photosensor is photosensitive. The respective center lines for openings for each set of photosensors are not collinear in the Y direction. In an example embodiment, the plurality of openings includes at least one row of openings substantially aligned in an X direction, orthogonal to the Y direction. In an example embodiment, each opening has an equal width in an X direction, orthogonal to the Y direction.

    摘要： A method measures the location of a sheet and then moves the sheet to a registered position. By measuring the actual location of the sheet and then moving the sheet to the registered position, the invention saves a substantial amount of time. An elongated array of LED sensors 130 stretches over several inches and is aligned with a collimated light source 110. Each sensor in the array is spaced from its adjacent sensor by a known amount. This amount can be as small as a few tens of thousandths of an inch. The edge of a sheet covers the sensors. The sheet edge is measured and the registration device moves the edge of the sheet to the registered position for receiving the developed image.
