摘要:
A method of forming a film of plastic material includes urging molten resin through a die head (106) to form a stalk (108) having an extrusion profiled rail (110) of resin material extending radially outward from a tubular wall, then cutting the rail (110) to form discrete elements (114) while leaving the tubular wall un-punctured, and inflating the stalk (108) with a gas bubble maintained within an interior space of the tubular wall to form a thin film tube (120) carrying discrete elements (114) such as fastener elements.

A hook strip is provided having a backing with a first surface and a length in a first direction; multiple rows of hook elements aligned in the first direction and projecting from the first surface of the backing; and slits in the backing between at least some pairs of adjacent rows of the hook elements. The slits may be interrupted by a bridging region of the backing, or the slits may be partial slits that penetrate the thickness of the backing in a range from 40 to 90 percent. A fastening laminate that includes a carrier and the hook strip described above joined to the carrier is also provided. In some embodiments, the fastening laminate includes slits that form separate, abutting portions of the backing on the carrier. An absorbent article containing the hook strip and a method of making the hook strip are also disclosed.

Various method of making RFID tags, RF-responsive antennae and other circuitry in flexible sheet form with touch fastener elements extending from one side of the sheet, for securing the tags. Some methods include continuous roll forming methods and/or the filling of molded channels with conductive compositions.
摘要:
A flexible circuit has a roll-molded thermoplastic resin base sheet with an integrally molded mounting structure located to receive a light emitting diode device in an illuminating position. The mounting structure is a pin receptacle constructed to receive a pin of the light emitting diode device. An electrically conductive portion is carried by the resin base and positioned for electric connection to conductors of the device. Another flexible circuit carries discrete integrated circuit chips and a field of fastener elements extending from a surface of a resin strip carrying conductive traces interconnecting the chips.

The present invention provides a method for forming preferably a unitary polymeric hook fastener(20) comprising a flexible backing(22), and a multiplicity of spaced hook elements(9) projecting from the upper surface of the unitary backing(22). The hook elements(9) each comprise a stem portion(24) attached at one end to the backing(22), and a head portion(21) at the end of the stem portion(24) opposite the backing(22). The head portion(21) projects in different directions for some adjacent hook members(9) which adjacent hook members(9) each have a flat face(35,36) which flat faces(35,36) are mutually opposing in face to face relation.
