Publication number: 20220339897Abstract: A meshwork has a layer forming a mesh, the mesh layer being disposed between parallel tension ribbons which are opposite one another in pairs. The tension ribbons have a thermoplastic bonding layer on the side facing the mesh layer and are connected to one another and to the mesh layer via the bonding layer. The mesh layer takes the form of a plastic net having meshwork webs which are connected to one another in a materially bonded manner and which are stretched and form diamond-shaped meshes, the longitudinal diagonals of which extend transversely to the tension ribbons.Type: ApplicationFiled: September 9, 2020Publication date: October 27, 2022Inventor: Friedrich Landertshamer

Patent number: 10934042Abstract: A method is provided of making form fill and seal (FFS) bag formed at least in part from an open mesh material that includes filaments that intersect one another. At least some of the filaments are composite filaments having a carrier portion of a relatively high melting point and a bonding portion of a relatively low melting point, the bonding portion of each composite filament being thermally bonded to other filaments at points of intersection. The material may be a non-woven fabric that contains at least two layers of weft filaments that may be bordered on one or both sides by a layer of warp filaments. When compared to other open mesh materials, the open mesh material disclosed herein has a superior combination of some or all of high strength, light weight, high dimensional stability, and openness.Type: GrantFiled: April 21, 2017Date of Patent: March 2, 2021Assignee: Volm Companies, Inc.Inventors: Robert Frei, Corbett Hefner, Friedrich Landertshamer, Alan Mueller

Patent number: 8784967Abstract: An open mesh material includes filaments (1, 2, 3, 4, 11, 12, 15, 16) that intersect one another. At least some of the filaments are composite filaments having a carrier portion of a relatively high melting point and a bonding portion of a relatively low melting point, the bonding portion of each composite filament being thermally bonded to other filaments at points of intersection. The material may be a non-woven fabric that contains at least two layers of weft filaments (1, 2, 11, 12) that may be bordered on one or both sides by a layer of warp filaments (3,4, 15, 16). When compared to other open mesh materials, the open mesh material disclosed herein has a superior combination of some or all of high strength, light weight, high dimensional stability, and openness. Also disclosed herein are articles can be made at least in part from the material including L-seam bags (20), form fill and seal (FFS) bags (1020), and multi-substrate bags (2,020). Methods of making those bags also are disclosed.Type: GrantFiled: October 7, 2010Date of Patent: July 22, 2014Assignee: Volm Companies, Inc.Inventors: Robert Frei, Corbett Hefner, Friedrich Landertshamer, Alan Mueller

Patent number: 8784969Abstract: A meshwork made of ribbons (1, 2) is described which are connected with each other by way of a thermoplastic filler material. In order to provide simple constructional conditions it is proposed that the ribbons (1, 2) which are laid in at least two groups and intersect one another in groups are fixed between two cover layers (3, 4) with respect to their mutual position, which layers have an at least two-layer configuration with a bonding layer which faces the ribbons (1, 2) and is made of a thermoplastic material and with a carrier layer having a higher tensile strength, which layers are connected with each other and with the ribbons (1, 2) by way of the bonding layer.Type: GrantFiled: December 21, 2009Date of Patent: July 22, 2014Inventor: Friedrich Landertshamer
