摘要:
The device includes a toothed wheel on which pleats of a sheet 10 are preformed, in some cases with the aid of a second toothed wheel 31, and a device for holding by a vacuum; then the preformed pleats are transferred to a pleat gathering wheel 13 either directly or through the medium of a pleat pressing wheel, where they are laid down then fixed to form a pleated sheet 23. The toothed wheels 5 and 31 and the pleat pressing wheel and/or the pleat gathering wheel 13 can be arranged to produce areas with no pleats at regular intervals.
摘要:
The disclosure relates broadly to sewing machines and provides a machine for pleating a fabric or other sheet material by passing it between intermeshed toothed rollers which produce pleats and deliver the material onto needles which are supported by the rollers.

The present invention relates to a process for the manufacture of a three-dimensional nonwoven, a manufacturing line for implementing this process and the resulting three-dimensional nonwoven product. Process characterized in that it consists in using a folding element (5) to apply, to an incoming web containing a proportion of thermoplastic fibers and/or filaments or fixing material, an initial fixing of the fold of the incoming web in the form of peaks and troughs, brought about by blades extending radially on ends of the folding element (5), this initial fixing being applied either by maintaining the folding element (5) itself at a set temperature, or by heating the incoming web. The invention is more particularly applicable to the textile industry, especially the manufacture of nonwovens.
摘要:
A system for pleating a continuous strip of foldable material including feeding the strip of foldable material between adjacent flights of cooperatively positioned endless conveyors having pleat folding arms pivotally associated therewith which are alternatively and interfittingly positioned to pleat the strip of foldable material as it movingly passes from one end of adjacent flights to the other end thereof.
