Abstract
An automatic apparatus for folding sheet elements fed one after the other in succession, comprising a first unit for U-shaping the sheet elements to define two vertical side portions and a longitudinal central region, a pusher element for V-shaping the central region and a second unit for the final compaction of the V-shaped sheet elements. The apparatus also comprises a third unit for rotating the folded compacted sheet elements leaving the second unit through 90.degree. and elements for separating the parallel side-by-side edges of the thus folded and compacted sheet elements to enable further additional elements to be inserted between them. The speed of the various units is correlated to prevent any deterioration or slippage of the sheet elements.
