Abstract
Support with meshes, or elastic flexible openwork grid, used for producing pile textile articles by inserting pile textile elements into its meshes, in which the grid possesses an extensibility of at least 40%, a permanent deformation of less than 5% and an immediate deformation of less than 10%. Pile textile articles are produced by inserting pile textile elements into the meshes of a flexible grid, in which articles a flexible planar element, which can easily be perforated and comprises a design, is associated with the grid. The pile textile elements are inserted over at least part of the surface of the design. The articles have decorative value as wall or floor coverings, wall hangings or similar decorative articles. A tool for introducing pile textile elements into a flexible meshed grid is a hollow conical member which is optionally open along at least one generatrix. Process for introducing pile textile elements into a flexible grid uses the inserting tool; a pile textile element is introduced into the wide part of the cone, the latter subsequently being forced into the mesh of the grid, narrow or pointed end first, and then removed from the grid, leaving in position the pile…
