ABSTRACT:
A holding device or "cradle" for holding a coil of sheet material so that the material can be unrolled from the coil and cut to length. The cradle takes the form of an open-topped tray having side walls and an end wall, the side walls supporting two horizontally disposed rollers upon which the coil is super-imposed. A third roller projects through the annular coil and is spring biased into contact with the interior of the coil to retain the coil in position. The unrolled sheet material is guided by the curved bottom onto a scoring or cutting bed which has spaced, parallel non-marring surfaces which are raised above the surface of the bed to define a cutting space therebetween. An upper score guide is moveable away from the scoring bed to accommodate the entry of sheet material therebetween and is moveable downwardly into contact with the sheet material to clamp the sheet material in position for cutting and to provide an elongated cutting edge which is aligned with the space between the non-marring surfaces. Further, the curved tray bottom is provided in a novel manner by compressing a planar metal sheet, in effect, between the tray side walls and the scoring bed.
