Also, that A specific example 'of the invention is illusalthough the stranded element has been detrated by the accompanying drawing, Figure 1 scribed as consisting of wires laid together, the

invention is equally applicable to elements made of parallel wires or, in fact, elements made of plural strands arranged together in any form and made of practically any material.

We claim:

1. A method of separating a strand of wires into shorter lengths, including die casting metal about said strand at spaced positions defining the shorter lengths and subsequently severing said metal and said strand to produce the shorter lengths in the form of units having die cast end fittings. I

2. A method,of separating a strand of wires severed into lengths and Figure 2 showing one of the resulting lengths.

More specifically, the numeral 4 indicates a continuous stranded element, it being undercharacter provided it is made up of a plurality of wires which are laid together.

The first step is illustrated by Figure 1, sleeves 2 being die cast about the element I at points which are spaced so that the mid-sections of these sleeves define the lengths desired. Die casting is construed as meaning the casting of molten metal into dies which are arranged to encompass the strand I, theresult being that the metal of the sleeves 2 engages not only the surface of the element, but also the surfaces of the individual wires of which the. element is made, and is down in the interstices between the latter. The next step is to sever the element at the about said strand at spaced positions defining the shorter lengths and subsequently severing said metal andsaid strand to produce the shorter lengths in the form of units having die east end fittings, said die casting being conducted by means of dies encompassing said strand so that said of the wires forming said strand and penetrating into the interstices between said wires.

wheels 3. The result is a series of lengths which are each of the character illustrated by Figure 2. Each of the lengths carries a half of one of the die cast sleeves on each of its ends, and unravel.-

into shorter lengths, including die casting metal,

metal is formed as sleeves engaging the surfaces
