摘要：
A method for manufacturing a deflection member is disclosed. The method may include the steps of providing an additive manufacturing apparatus that includes at least one radiation source and a vat containing a photopolymer resin, providing a reinforcing member, contacting a surface of the reinforcing member with the photopolymer resin, and directing radiation from the at least one radiation source towards a surface of the reinforcing member to at least partially cure photopolymer resin in contact with the surface of the reinforcing member to create at least a portion of a lock-on layer.
技术问题语段：
The technical problem addressed in this patent is the need for improved deflection members in papermaking and non-woven making processes that can withstand extreme temperatures, tensions, and pressures in a cyclic process. The deflection members need to have any three-dimensional topography afforded by additive manufacturing and also include a separate reinforcing member to endure the evolving processing environment of a fibrous web making machine.
技术功效语段：
The patent text describes a method for manufacturing a deflection member using an additive manufacturing apparatus. The method involves submerging a reinforcing member into a photopolymer resin and directing radiation from the apparatus to partially cure the resin in contact with the reinforcing member to create a lock-on layer. The resulting deflection member has improved strength and flexibility. The technical effects of this method include improved manufacturing efficiency and enhanced strength of the deflection member.
权利要求：
1. A method for manufacturing a deflection member suitable for the production of fibrous webs, the method comprising the steps of: a.) providing an additive manufacturing apparatus that comprises at least one radiation source and a vat comprising a photopolymer resin; b.) providing a reinforcing member having a first surface and a second surface opposite the first surface; c.) contacting at least the second surface of the reinforcing member with the photopolymer resin; and d.) directing radiation from the at least one radiation source towards the first surface of the reinforcing member such that the radiation passes through the first surface of the reinforcing member to at least partially cure photopolymer resin in contact with the second surface of the reinforcing member to create at least a portion of a lock-on layer.
2. The method of claim 1, wherein the additive manufacturing apparatus is an SLA apparatus or a CLIP apparatus.
3. The method according to any of the preceding claims, further comprising the steps of submerging the reinforcing member into the photopolymer resin and directing radiation from the at least one radiation source to at least partially cure photopolymer in contact with the first surface of the reinforcing member to create at least a portion of the lock-on layer.
4. The method according to any of the preceding claims, further comprising a step of directing radiation from the at least one radiation source to at least partially cure photopolymer in contact with the lock-on layer to create a build layer.
5. The method according to claim 4, further comprising the step of directing supplemental radiation towards the deflection member to further cure at least one of the lock-on layer and the build layer.
6. The method according to any of the preceding claims, wherein the reinforcing member comprises foramina, the foramina each having at least one sidewall surface located between the first surface and the second surface of the reinforcing member.
7. The method to claim 6, further comprising the steps of contacting the sidewall surfaces of at least some of the foramina with the photopolymer resin and directing radiation from the at least one radiation source to cure photopolymer resin in contact with the sidewall surfaces of at least some of the foramina to create at least a portion of the lock-on layer.
8. The method according to any of claims 1-5, wherein the reinforcing member comprises woven filaments and voids between the woven filaments, each void having at least four side surfaces located between the first surface and the second surface of the reinforcing member.
9. The method of claim 8, further comprising the steps of contacting at least one of the side surfaces of at least some of the voids with the photopolymer resin and directing radiation from the at least one radiation source to cure photopolymer resin in contact with the at least one side surface to create at least a portion of the lock-on layer.
10. The method according to any of the preceding claims, wherein the at least one radiation source is an upper radiation source disposed over the vat.
11. The method according to any of claims 1-9, wherein the at least one radiation source is lower radiation source disposed under the vat.
12. The method according to any of claims 1-9, further comprising a second radiation source directing radiation toward the second surface of the reinforcing member to at least partially cure photopolymer resin in contact with the second surface of the reinforcing member.
13. The method according to any of the preceding claims, further comprising forming a resinous framework via curing the photopolymer resin.
14. The method according to any of the preceding claims, wherein the resinous framework extends from the reinforcing member.
15. The method according to claim 14, wherein the resinous framework and the reinforcing member form the deflection member.
