Abstract: Apparatus for the continuous electrolytic treatment of wire-shaped objects comprising an electrolyte bath and means for conducting the objects predominantly horizontally through the bath past a succession of anodes and cathodes, wherein the objects follow a zigzag path of travel in sliding contact with the successive current-transmitting electrodes that are immersed in the electrolyte and connected to one and the same pole of the power source.

Abstract: The invention relates to a reel (1) comprising a core (2) and two flanges (3) holding elongated material (4), such as wire, ribbon-like material, etc. wound on the core (2) between the flanges (3) and whereby each flange (3) of the reel (1) is a substantially rectangular panel (3) (see FIG. 1). More in particular, the invention relates to a crate (10) containing one or more reels (1) and comprising at least four vertical walls, a base and a top, whereby the base and the top of crate (10) are symmetrical and have been provided with supporting elements (11) to accommodate the ends (6) of the flanges (3) of the reels (1) held in the crate (10).

Abstract: The invention relates to a method whereby wire is coiled conically on to a spool. The spool has at least one conically formed flange. The number of windings per layer is gradually increased during the coiling operation.
