Abstract: Methods for making curved pieces from continuous metal elements are provided. Such methods include advancing a continuous metal element through a calendering station such that each length of the element assumes a pre-established curvature; stopping advancement of the element after a curved length thereof has passed through a wrap-bending station located downstream of the calendering station; wrap-bending the length of the element located at the station, while simultaneously conveying the curved portion to a stretch-bending station; stretch-bending the curved portion; resuming advancement of the element until the wrap-bent length is at a cutting station; and cutting the element in the wrap-bent length, thus producing the desired curved piece. Curved pieces produced by such methods are also provided.

Abstract: Frames for vehicles, such as buses or industrial transport vehicles, are provided which may be formed by a plurality of welded elements including ribs, cross members and uprights. At least one upright maybe formed by a first section bar welded to a second section bar, thereby forming a closed, hollow cross-section. Methods of making and using such frames are also provided.

Abstract: A reinforcing bar for body and/or chassis parts of a motor vehicle includes a one-piece element (8) extending from one end of the bar to the other and having a median portion (10) with closed tubular cross-section and at least one end portion (12) comprising an open-section distal portion (14) and a proximal portion (16) which connects the said distal portion (14) to the median portion (10).

Abstract: The reinforcement bar for motor vehicle body components, in particular an anti-intrusion bar for doors, has in cross-section at least one omega-shape element (10) comprising two horizontal base sections (12) from which extend respective vertical sections (14) joined at the top by a further horizontal section (16), or at least one inverted U-shaped element (28) comprising two vertical sections (14) joined at the top by a further horizontal section (16). The bar has respective longitudinally extending slots (18) in the vertical sections (14) at at least one end in such a way that it allows the end of the bar to be shaped in conformity with the assembly requirements of the motor vehicle body components to re reinforced.

Abstract: The frame is intended to be mounted on a lower panel of a motor vehicle door. It comprises two uprights, a front upright and a rear upright respectively, joined at their upper ends by a cross member and adapted to define, together with upper edge of the lower panel, a space for the window associated with the door. The uprights and the cross member are formed by at least two shaped elements joined longitudinally so as to form a box structure. The frame can thus assume the desired three-dimensional configuration and its dimensions can vary in the general plane of the door and in the direction perpendicular thereto. The uprights may also extend downwardly so as to constitute a reinforcement for the side edges and portions of the lower edge of the lower panel adjacent thereto.
