Folding apparatus for sheet layers |
摘要 |
Folding stations are provided successively in a single running direction of an apparatus for the single or z-like folding of lateral tongues of a sheet layer. The first station has an offset rising folding curve for tongue straightening, the second station has a rotating roll for z-shaped prefolding of a tongue, and the third station has juxtaposed folding curves for the finish folding of differently long tongues and the first pressing rolls for the smoothing of the fold breaks. Therefore, very different and complicated folds can be carefully made in a single pass through the apparatus.
