Manufactured by: Ateliers Onderka, Görlitz (D), in the 1930sOrigin: donation from the Higher Industrial Institute in VerviersVerviers Museum Collection: No. A90Decatising enables the twist of the yarn to be set so that it does not coil during later weaving operations and so that it regains its natural moisture content in order to ensure greater solidity. Spindles are placed in perforated baskets placed in the closed tank of the machine into which steam is introduced. Next, the spindles are placed on a winder for coning, before warping takes place (preparation of the warp threads) and then weaving.
