  • Patent number: 4179083
    Abstract: This invention relates to a wire forcing device on a distributor of a wire take up apparatus to take up a wire such as an electric cable on a reel in an arranged manner. The wire forcing device has wire engaging means to force a first turn of a wire winding layer against either end of the reel. The wire engaging means may comprise a pair of guide members of the distributor, or may be separate from the guide members. If the wire engaging means comprises the guide members of the distributor, while the wire is taken up on the reel between the flanges thereof, the wire engaging means guides the wire for transversely distributing the wire, and just before a first turn of a new winding layer begins to be wound adjacent to either of the reel flanges or while the first turn of the new winding layer is wound, either of the guide members forces the wire against the corresponding reel flange.

  • Patent number: 4034933
    Abstract: In reel mounting means for a wire take up apparatus comprising a pair of spindles axially movable so that the opposing ends of said spindles are received into an axial hole in a reel and so that a relatively thicker wire such as an electric wire or an electric cable extending through an opening in one of the flanges of said reel with the end of said wire leading out of said reel flange is fixed between said reel flange and the corresponding spindle, characterized by that at least one of said spindles on the side facing the corresponding reel flange is provided with a pressurizing plate to be exerted so that it is pressed against said reel flange. The pressurizing plate includes a reel flange pressurizing body to be forced against said reel flange and a wire end securing body to force said wire end against said corresponding reel flange whereby it is fixed between said pressurizing plate and said corresponding reel flange.

  • Patent number: 3997128
    Abstract: In an apparatus for taking up a relatively thicker wire such as an electric wire or an electric cable on a reel, comprising a distributor for distributing said wire along the axis of said reel, wire raising up detecting means is provided which electrically detects that a first turn of a new winding layer of said wire is being raised up on the reel adjacent to either of the flanges of said reel, so that it produces an electric signal to instruct said distributor to move in a reverse direction. The detecting means is characterized to comprise at least two adjacent arms pivotally mounted on a fixed axis parallel to the axis of said reel to be engaged against the wire wound on said reel; and an angular-electro converter to convert the angle at which said arms are pivotally moved relative to each other into an electric signal having the amplitude proportional to the angle.
