(Cl, 117-20) This invention relates to an improved closing continuous ring preferably will be free to rotate head for making wire strand or rope'in which the under the pressure of the wires or strands or be individual wires or strands are laid up helically mechanically rotatedso as to relieve the friction about a core and compressed by a squeezer in thereon which otherwise would result. from the closing. rotating movement of the wires or strands in 5 The object of the invention is to provide a closing, and to present new surfaces of the die construction which shall avoid the objections into the wires or strands continually and thus avoid herent in previous closing devices employing a unequal wear and deformation of the entrance squeezer, and further to provide a construction portions-of the die. suitableby simple adjustment for being used for For a full understanding of the invention, there producing preformed rope, that is, rope in which is shown in the accoinpanying drawing a closing permanent helices are formed'as or before the head embodying the invention in a preferred wires or strands are laid up on the core, or the form and this construction will now be described ordinary standard rope withoutsuch permanent in detail and the features forming the invention helices. then specifically pointed out in the claims.

The die formed by the closing, but the die and squeeze: may be adiusted 56 axially to any position desired for making either preformed or standard strand or rope.

It will be understood that the invention may be used in any type of rope making machine in which the wires or strands are laid up helically to form a strand or rope, either in machines in which the closing head is rotated for forming the helices or the rope is rotated and the closing head stationary. It will be understood, also, that the invention is not limited to the particular construction of closing head shown, but that many modifications may be made therein while retaining the invention as defined by the claims.

What I claim is:

1. In a strand or rope closing head, the combination with a split squeezer and guides rela tively orbitally movable with respect to the squeezer over which guides the wires or strands pass to the squeezer, of a die formed or a con tinuous ring located between the squeezer and guides and acting to lay up the wires or strands helically to form strand or rope before passing to the squeezer, and means for varying the angle at which the wires or strands pass from the guides to the die by adjusting the die axially toward and from the guides.

2. In a strand or rope closing head, the combination with a split squeezer and guides relatively orbitally movable withrespect to the squeezer over which guides the wires or strands pass to the squeezer, of a die formed of a continuous ring with rounded entrance edges for the wires or strands located between the squeezer and guides and acting to lay up the wires or strands helically to form the strand or rope be fore passing to the squeezer, and means for varying the angle at which the wires or strands pass from the guides to the die by adjusting the die axially toward and from the guides.

3. In a strand or rope closing head, the comblnation with a split squeezer and guides relatively orbitally movable with respect to the squeezer over which guides the wires or strands pass to the squeezer, of a die formed of a continuous rotatable ring located between the squeezer and guides and acting to lay up the wires or strands helically to form strand or rope before passing to the squeezer, and means for varying the angle at which the wires or strands pass from the guides to the die by adjusting the die axially toward and from the guides.

4. In a strand or rope-making machine, the combination with a closing die having a smooth cylindrical bore whose diameter is slightly greater than the maximum diameter of the finished strand or rope, and having a convexly rounded edge at the entrance end of said bore, a plurality oi guides for the wires or strands, said guides being located in a plane in advance of the closing die and being relatively orbitally movable with respect to the axis of its bore, all of said guide devices being arranged to deliver directly wires or strands at a predetermined, constant but adjustable angle, into tangential contact with the rounded edge of the closing die, whereby each wire or strandjust before it enters the cylindrical bore of the closing die is bent by said rounded edge, and a two-part squeezer having its two parts slightly separated, said squeezer being arranged to squeeze the strand or rope to its finished size immediately on its emergence from the closing die, of means for adjusting the closing die and the squeezer toward or from the orbital plane of the guide devices to vary the angle and point of tangency of each wire or strand at said rounded edge.
