摘要： A clamp for connecting together a set of structural bars having a body defining at least one pair of prismatic guides for positioning one of the bars within the clamp and a locking mechanism for securing the bars inside the guides. The body is defined by four sheet metal plates arranged parallel and facing each other in pairs of two, each pair of two arranged perpendicular to the other such that each pair is connected to the other collectively along four parallel edges of the body. The prismatic guides are each defined by a pair of aligned seats formed along respective sides of each pair of facing plates.

摘要： In a machine for forming articles of sheet material, an orderly succession of flat blanks is fed along a forming path on a roller conveyor having powered rollers equally spaced with a given spacing; on the roller conveyor, the blanks are maintained contacting the rollers by idle-wheel pressure devices, and are deformed by folding devices; the pressure devices and folding devices being fitted to respective gantry-type frames having respective removable cross members, and which can be set to a number of predetermined reference positions and locked in such positions releasably with respect to the roller conveyor; and a continuous guide and slide adjusting assembly being interposed between each frame and the respective pressure devices and folding devices to adjust the position of the devices on the roller conveyor as a function of the shape and size of the blanks.
