FILAMENT FOR EXTRUSION-BASED ADDITIVE MANUFACTURING SYSTEM
20180001585 · 2018-01-04 ·

A filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The reinforcement and matrix portions run continuously along a length of the filament. The reinforcement portion has a higher melting point and a higher crystallinity than the matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The partially molten filament is extruded from the extrusion head onto a substrate, the reinforcement portion of the partially molten filament remaining in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

WEATHERSTRIP CARRIER THAT REMOVABLY ATTACHES TO FENESTRATION UNIT
20230027784 · 2023-01-26 · ·

A weatherstrip carrier of a replaceable weatherstrip system for a fenestration unit includes a weatherstrip support configured to hold a weatherstrip. The weatherstrip carrier also includes a coupling member that is attached to the weatherstrip support. The coupling member is configured to removably attach to the fenestration unit. The coupling member includes a spine, a first projection, and a second projection. The first and second projections project from the spine in a common direction. The coupling member is resiliently flexible for movement between a neutral position and a flexed position. The first and second projections are biased toward each other when the weatherstrip carrier is in the flexed position. The second projection is configured to be removably received within the fenestration unit, with the weatherstrip carrier in the flexed position, and with the first and second projections cooperatively compressing against the fenestration unit to retain the weatherstrip carrier thereon.

Extrusion with preferential bend axis

A catheter is made by coextruding first and second molten polymers, wherein the second molten polymer forms a flexible inner core and the first molten polymer forms exactly two bands on opposite sides of the inner core. The inner core is braided, and a third molten polymer extruded onto the braid to form a flexible jacket that encloses the braid, the bands and the inner core. The bands are more rigid than the inner core, and they provide preferential in-plane bending.

Method and apparatus for making a compartmentalized tire sealant strip

A method for making a compartmentalized sealant strip and barrier assembly 10 has the steps of co-extruding a barrier strip 9 of non-sealant elastomeric material with a plurality of projecting linear extending walls 9c and a sealant strip 11 wherein the sealant strip 11 is formed on one side of the barrier strip 9 filling the space between the plurality of projecting walls 9c to form a plurality of linearly extending rows of sealant 11 across the transverse width of the co-extrusion to form the compartmentalized sealant strip and barrier assembly 10. The step of co-extruding may further include the step of: forming the projecting walls 9c on an inclined angle relative to a plane perpendicular to the width of the assembly 10. The step of co-extruding further has the step of forming the barrier strip 9 with lateral edges 9a and 9c that extend beyond the lateral outermost sealant strips 11 on each side of the assembly 10, the lateral edges 9a, 9b being bonding surfaces to seal the sealant strip and barrier assembly 10 into an uncured rubber layer when assembled into an unvulcanized tire 2.
