Abstract: The invention relates to a roller for a chain which is constructed by a shell roller part and a core roller part, wherein the shell roller part comprises a first outer cylinder, a first inner cylinder which is positioned concentrically inside the first outer cylinder, and a bottom which is positioned at and connected to one end of the first inner cylinder and the first outer cylinder; and wherein the bottom is stretched from the first inner cylinder to the first outer cylinder; wherein the core roller part comprises a second outer cylinder, a second inner cylinder which is positioned concentrically inside the second outer cylinder, and a top which is positioned at and connected to one end of the second inner cylinder and the second outer cylinder; and wherein the top is stretched from the second inner cylinder to the second outer cylinder; wherein the core roller part is positioned concentrically in the space surrounded by the first inner cylinder, the first outer cylinder and the bottom.

Abstract: The disclosure relates to a dipping former, to a process for producing the dipping former and to the use of the dipping former in a latex dipping process. The dipping comprises (i) a molded core part, and (ii) a dipping former shell having a surface in one piece. The dipping former is obtainable by a molding process comprising the following steps: —providing a first cavity and a second cavity; —injection molding or blow molding a first material into the first cavity thereby forming a molded core; —transferring the molded core form the first cavity into the second cavity; and —injection molding of a second material into the second cavity thereby overmolding the molded core, or at least a part thereof, with the second material.
