Patent number: 7188396Abstract: A mushroom-type hook strip for a hook-and-loop fastener has a flexible backing of thermoplastic resin and, integral with backing, an array of upstanding stems distributed across at least one face of the backing, each having a mushroom head. The stems have a molecular orientation as evidenced by a birefringence value of at least 0.001. The mushroom-type hook strip can be produced continuously by injecting resin into cavities of a cylindrical mold while evacuating and cooling the cavities so that the cooled resin becomes molecularly oriented, thus affording to the stems excellent stiffness, durability, and tensile and flexural strength.Type: GrantFiled: October 20, 2003Date of Patent: March 13, 2007Assignee: 3M Innovative Properties CompanyInventors: William L.

Patent number: 7185401Abstract: A method for forming a unitary polymeric projection or fastener comprising a thin, strong flexible backing, and a multiplicity of thin spaced hook members projecting from the upper surface of the unitary backing the method generally including extruding a thermoplastic resin through a die plate which die plate is shaped to form a base layer and spaced ridges, ribs or hook elements projecting above a surface of the base layer. When the die forms the spaced ridges or ribs the cross sectional shape of the hook members are formed by the die plate while the initial hook member thickness is formed by transversely cutting the ridges at spaced locations along their lengths to form discrete cut portions of the ridges. Subsequently longitudinal stretching of the backing layer (in the direction of the ridges on the machine direction) separates these cut portions of the ridges, which cut portion then form spaced apart hook members.Type: GrantFiled: December 20, 2004Date of Patent: March 6, 2007Assignee: 3M Innovative Properties CompanyInventors: Ronald W.

Patent number: 7141098Abstract: A filtration system for filtering particulates from air. A plurality of point ionization sources are positioned in the proximity of the periphery of an air flow channel and being oriented to generate ions in the proximity of the air flow channel in a direction generally upstream from each respective one of the plurality of point ionization sources. A particulate collection surface is positioned within the air flow channel in a downstream direction from the plurality of point ionization sources. The particulate collection surface is electrostatically charged in an opposite direction with respect to ground than the electrical charge of the ions. An ion trap is positioned within the air flow channel between the plurality of ionization sources and the particulate collection surface.

Patent number: 7137539Abstract: An apparatus and method of converting a web of indefinite length into a plurality of web portions by slitting the web at a transverse point prior to processing the web portions into a plurality of use supply forms (such as rolls), wherein the plurality of web portions are separated by a two-stage process. A first stage of the process is a partial separation operation that almost entirely separates the web portions, but leaves the web portions connected, such as by a slitting operation that leaves a series of connected zones. The second stage includes the complete separation, such as by breaking of the connected zones. The complete separation of the web portions preferably occurs near the station at which the use supply forms are created, such as a winding station. Thus, the web portions, after substantial separation at the first stage can be handled (for example, guided and tensioned) as if the plurality of web portions were a full width web.Type: GrantFiled: April 19, 2002Date of Patent: November 21, 2006Assignee: 3M Innovative Properties CompanyInventor: Byron M.

Patent number: 7067185Abstract: A unitary fastener of a thermoplastic resin comprising a base film layer having generally parallel upper and lower major surfaces, arranged in a first direction the base film layer being oriented at least in the first direction. The backing layer having on at least one surface separated surface elements extending at an angle to said first direction. The invention is also related to a method of forming a unitary fastener. The method includes the steps of extruding a thermoplastic resin in a machine direction through a die plate having a continuous base portion cavity and one or more rib cavities extending from the base portion cavity, forming a strip having a base layer and continuous rib. This scoring or cutting the ribs and at least a surface layer of the film structure forms predetermined separable elements. This inelastically stretching the strip to separated projections and the separated separable surface elements across the strip.Type: GrantFiled: June 11, 2003Date of Patent: June 27, 2006Assignee: 3M Innovative Properties CompanyInventors: Ronald W.
