  • Patent number: 5885523
    Abstract: A device for continuously heat-treating continuously cast or formed metallic goods, particularly wire and the like. The device comprises a first annealing path in which the continuously formed metallic goods are guided by means of two contact rollers. The first and second contact rollers are arranged at first and second ends, respectively, of the first annealing path. Moreover, the first and second contact rollers are connected to a voltage source such that a current flows through the continuously formed metallic goods between the first and second contact rollers. The device further comprises a second annealing path similar to the first annealing path.

  • Patent number: 4971264
    Abstract: A method and apparatus for the continuous changing of reels on continuously operating stationary winding stations for strand-like materials are disclosed. A reel changing apparatus having at least two reel receiving stations is provided. A full reel being wound on a winding station is removed from the winding station by a first reel receiving station of the reel changing apparatus which continues to rotate the removed reel at operating speed after reel removal. Strand-like material continues to be wound on the removed reel. A second reel receiving station of the reel changing apparatus which is rotating an empty reel at operating speed places the empty reel on the winding station from which the full reel had been removed. The empty reel rotates on the winding station at operating speed. The strand-like material is then cut and transferred to the empty reel rotating on the winding station. Reel change has been accomplished without interrupting the winding of the strand-like material.
