The present invention relates to the protection of blank areas of sheet metal otherwise coated with layers of synthetic materials, lacquers, foils or the like, wherein apparatus is provided for covering the blank areas with tape or cord by temporarily moving a means for applying the tapes or cords towards, along and away from the sheet material and, if desired, pressing the same on and/or drying the same on the sheet metal.

Apparatus for laminating a protective laminate to the cut edge of sheet metal otherwise coated with a Corrosion-proof layer, for protecting the cut edge of the sheet metal from corrosion, comprising: storage means providing a source of the corrosion resistant laminate in a continuous indefinite length in coiled form mounted for rotation about an axis to facilitate withdrawal of said laminate material in an elongated form from said coil; means for guiding the indefinite length laminate from the coil form to an elongated form adjacent to and generally corresponding to the contour of the cut edge of the sheet metal to be protected from corrosion, said guide means including a generally U-shaped fixed guide channel having its web portion decreasing in width and its legs continuously becoming more closely spaced together from one end to its opposite end, so that the laminate in tape form entering its one end will exit its opposite end in U-shaped folded form around the sheet metal edge, and a plurality of tape pressing rollers having their axes transverse to the tape and at angles with respect for each other for engaging respectively the tape portion engaging the cut sheet metal edge and the tape portions engaging the coated areas of the sheet metal adjacent the cut edge; means for moving said laminate is elongated form transverse to its length toward the adjacent sheet metal cut edge and pressing said laminate onto said sheet metal cut edge and onto the coated areas of said sheet metal adjacent said cut edge to permanently bond said laminate to said sheet metal cut edge and the coated areas of sheet metal adjacent said cut edge; means for retaining the sheet metal in a fixed position; a plurality of guide rails in fixed position parallel to the cut edge of the sheet metal cut edge in its fixed position; a support carriage having mounted thereon said storage means and said means for guiding, and including a plurality of guide rollers engaging said guide rails so that said carriage may be moved parallel to and at a fixed distance from said sheet metal cut edge; power means for driving said carriage along said guide rails, and means immediately adjacent said laminate when elongated for heating both said laminate and said sheet metal cut edge prior to assembly; heat insulation and heat sink means immediately adjacent the opposite coated surfaces of said sheet metal spaced from said cut edge so as to prevent substantial heating of said sheet metal apart from the area where it will be directly engaged by the laminate after assembly.
