  • Apparatus for treating a sheet material with radiation
    Patent number: 4177383
    Abstract: Apparatus for treating a sheet material with radiation comprises a lamp assembly and gripper means for moving the sheet material along a path past the lamp assembly. The gripper means has a portion which overlies a part of the surface to be treated and the lamp assembly is adapted to produce a beam of radiation having a main focus substantially on the path. The beam is angled relative to the path so that a substantial portion of the overlain surface part is exposed to focused radiation as the sheet material is moved along the path.
