ABSTRACT:
There are disclosed a process for the continuous production of open, composite reticulated structures consisting of at least two superimposed or overlapping fibrilled films of synthetic polymers, and apparatus for effecting the transversal opening or stretching (with respect to the slitting or fibrilling direction) of a fibrilled film or of a combination of at least two superimposed fibrilled films and which comprises a feeding system for the fibrilled film, a pair of diverging guides each closing upon itself in the form of a ring for transverse stretching of the film, a series of clamps sliding on guides for gripping the edges of the film or film assembly, means for feeding the clamps to the guides, a series of two pulling means for engaging the clamps, means for opening the clamps and dragging them along the guides to the feeding devices, and means for take-up of the open film or the assembly of open films.
