    摘要： A paper folding station (10) comprises: a frame (11); a paper-feeder (12); a first pair of motorised, substantially adjacent rollers (18,20) supported at the delivery end of the paper-feeder (12) about respective parallel axes to draw sheets of paper from the feeder (12), one roller (20) of said first pair being mounted on a first support (22) adjustable in position to change the distance between said rollers of the first pair; a folding buckle (16) arranged to receive the sheets from said first pair of rollers (18,20) through an inlet mouth (I) and having a barrier (70) causing the sheets to stop and to bend into the shape of a groove below the inlet mouth (I); a second pair of motorised, substantially adjacent rollers (18,28) supported near said inlet mouth (I) about respective parallel axes to pinch the groove (D) and to make a transverse fold on the sheet, one roller (28) of said second pair being mounted on a second support (30) adjustable in position to change the distance between said rollers of the second pair. The paper-folding station further comprises at least one transverse beam (74,76) which is connected to follow the changes in position of a respective one of said first support (22) and second support (30) and is arranged to guide the sheet near the inlet mouth (I).

    摘要： In a machine (1) for forming articles of sheet material, an orderly succession of flat blanks (2a) is fed along a forming path (K) on a roller conveyor (4) having powered rollers equally spaced with a given spacing (P); on the roller conveyor (4), the blanks (2a) are maintained contacting the rollers by idle-wheel pressure devices (15), and are deformed by folding devices (52)(53); the pressure devices (15) and folding devices (52)(53) being fitted to respective gantry-type frames (19) having respective removable cross members (21), and which can be set to a number of predetermined reference positions and locked in such positions releasably with respect to the roller conveyor (4); and a continuous guide and slide adjusting assembly (35) being interposed between each frame (19) and the respective pressure devices (15) and folding devices (52)(53) to adjust the position of the devices on the roller conveyor (4) as a function of the shape and size of the blanks.
