Abstract:
A method for obtaining temporary non-stretchability characteristics, mainly in a machine direction, in a non-woven fabric having any level of stretchability, in order to ease converting is disclosed. The non-stretchability characteristics can be then eliminated in order to restore the original characteristics of the non-woven fabric. This technique allows the formation of final products comprising stretchable non-woven fabrics by converting machines.
Abstract:
An apparatus and method for perforating, cutting, or engraving a workpiece using a focused laser system to produce a focused laser. The apparatus includes a workpiece former having a complex shape to which the workpiece substantially conforms. The apparatus also includes a positioner that makes an adjustment to keep the focused laser substantially focused on the workpiece as the positional relationship between the workpiece former and the focused laser system changes to an operating position that changes the distance between the workpiece and the focused laser system due to the complex shape of the workpiece former.

Abstract:
A hybrid, shape-retaining nonwoven structure of at least two layers is disclosed, A first functional layer includes an expandable nonwoven sheet having an expansion character allowing for elongation in at least one direction and a second functional layer includes a shape-retaining material. The first functional layer and second functional layer are associated with each other.
Abstract:
The invention provides methods for producing flexible, stretchable, and/or elastic sheets and products having two or more zone having different material features and performance. The products can be comprised of material such as natural elastomers and other synthetic polymers. The method for producing stretchable products by spraying product material of different types over different zones of a workpiece former or conveyor belt,
Abstract:
The invention provides methods for producing flexible, stretchable, and/or elastic products comprised principally of material such as natural elastomers and other synthetic polymers. The method for producing stretchable products by spraying product material over a workpiece former, and method for creating perforated products by spraying product material over fibres in an upright position. The invention provides methods for making double sided fibre coating of the product and, or to at least coating the product surface on the side facing the wall without the need for removing the product from the wall.
