METHOD AND ARRANGEMENT FOR INSTALLATION OF RIBBON-TYPE ENCLOSING STRUCTURES Abstract of the Disclosure The invention comprises bending longitudinal edges of coiled ribbons toward the board elements of girders and drawing the ribbons over these elements wit subsequent fixing of bent edges thereto. Then the ribbons are tensioned lengthwise, and the bent edges are crimped around the board elements of the girders. The arrangement for effecting this method installa- tion comprises a coiled ribbon mounted in an uncoiling means a bending mechanism for shaping the ribbon to obtain a profi le corresponding to the shape of the board elements of gir- ders, and means for crimping the bend edges of the ribbon. The bending mechanism receiving the ribbon from the coil comprises a rigid frame disposed beneath the ribbon drawn between two adjacent girders which are rigidly connected to a pair of bilaterally symmetrical bending heads mounted to both end faces of the frame. Means for crimping the bent edges of the ribbon comprises a housing having a crimping head, the housing being connected to both ends of a cross- -piece movably mounted to the girder. One of the ends of the cross-piece is articulated to the housing and the other end thereof is connected to the housing by means of a clam- ping member. The invention may be the most efficiently used in in- dustrial construction and civil engineering for making walls ceilings and roofing.
