摘要:
A method for manufacturing a deflection member is disclosed. The method may include the step of incorporating a monomer, a photoinitiator system, a photoinhibitor, and/or a reinforcing member. A further step includes blending the monomer, photoinitiator, and/or photoinhibitor to form a blended photopolymer resin. Further steps may be emitting a first wavelength and emitting a second wavelength. A further step may be polymerizing the monomer to form a resinous framework comprising deflection member locked-on to the reinforcing member.
技术问题语段:
The technical problem addressed in this patent text is the need for improved deflection members in papermaking and non-woven making processes that can have complex shapes and be durable in extreme processing environments. The patent aims to provide a solution by utilizing additive manufacturing to create deflection members with separate reinforcing members that can withstand the processing environment of a fibrous web making machine. Additionally, the patent seeks to create deflection members with complex shapes that can require the emission of multiple wavelengths of radiation and the exposure of a photopolymer resin to form the desired complex shape.
技术功效语段:
The patent describes a method for making a deflection member by combining a monomer, a photoinitiator system, a photoinhibitor, and a reinforcing member. The monomer is then exposed to two different wavelengths of light to create a protuberance that extends from the reinforcing member. The technical effect of this method is a more precise and accurate way to make a deflection member that can control the movement and position of a target with greater precision.
