The device comprises a frame chassis 1 and a carriage 3 which can be driven linearly to and fro between guide rails 2 of the chassis 1 by pneumatic, hydraulic or electro-mechanical means. The frame chassis 1 and the carriage 3 are provided with exchangeable inserts which are located in bores 15, 16, 17 and act on a scaffolding element disposed therebetween to straighten or emboss same when the carriage 3 is moved. For the reception of frame- shaped scaffolding elements an elongate adjoint-piece 9 provided with an insert-locating bore 18 may be connected to the frame chassis 1. <IMAGE> |
