PROCEDURE AND PREPARATION FOR ESTABLISHING A STRENGTHENING FRAMEWORK FOR A SHIFTWORK HOUSEHOLD

摘要

Each folding cheek (10) contains three flange edges (20-22). For each clean flanging process a filling slide (34) is held against the edge area. The first flange edge (20) is used for pre-flanging the extending roof edge, the second flanging edge (21) is used for a further pre-flanging and the third flanging edge (22) is used as a ready-made flange. The roof with the reinforcement frame lies on a folding or flanging bed and between the individual flanging processes the folding cheeks are pushed forwards and backwards. The roof can be pushed against at least eight folding cheeks. The flanged edge area runs around at least 80 per cent of the roof opening.
