An in-situ wick rolling and forming assembly configured to roll and form a wick for a heat pipe from a wick mesh. The in-situ wick rolling and forming assembly includes a first forming shell, a slotted mandrel, and an expandable member. The first forming shell is configured to form the wick in-situ after the rolling of the wick mesh. The first forming shell includes a first recess and a first parting surface. A first central axis of the first recess is positioned below the first parting surface. The slotted mandrel is removably positionable in the first recess. L'invention concerne un ensemble de laminage et de formage de mèche in situ configuré pour laminer et former une mèche pour un caloduc à partir d'une maille de mèche. L'ensemble de laminage et de formage de mèche in situ comprend une première coque de formage, un mandrin à fentes et un élément expansible. La première coque de formage est configurée pour former la mèche in situ après le laminage de la maille de mèche. La première coque de formage comprend un premier évidement et une première surface de séparation. Un premier axe central du premier évidement est positionné au-dessous de la première surface de séparation. Le mandrin à fentes peut être positionné de manière amovible dans le premier évidement.
