Abstract
Abstract A connecting element, such as a bearing shell, is secured to and end of anrticle of manufacture having a large length relative to its diameter, by a combination of fiber strands or belts forming at least one loop, the ends of which form slings or bights which are anchored to the article by the turns of an anchoring winding extending around the article and through the slings or bights. The loop with its slings or bights is made simultaneously with the formation of the anchoring winding. This type of operation is possible because the turns of the anchoring winding hold down the fiber strands or belts as they are doubled-up to form the loop, preferably endless loops.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
An article of manufacture having a longitudinal axis, comprising a connecting element (1), a plurality of substantially longitudinally extending fiber loops (3) securing said connecting element (1) to one end of said article (2) so so that said fibers extend substantially in parallel to said longitudinal axis except where the fibers change direction to form said plurality of fiber loops (3) which are formed by a reciprocating motion, and at least one anchoring winding (4) for securing said plurality of fibers loops (3) to said article (2) of manufacture, said anchoring winding being produced by winding anchoring fibers to form a turn simultaneously with said reciprocating loop forming motion so that each longitudinally extending fiber loop is looped around said turn of said anchoring winding for securing the connecting element (1) to the article (2) of manufacture.
Claim 2
Dependent Claim
137 words
An article of manufacture having a longitudinal axis, comprising a connecting element (1), a plurality of substantially longitudinally extending fiber loops (3) securing said connecting element (1) to one end of said article (2) so so that said fibers extend substantially in parallel to said longitudinal axis except where the fibers change direction to form said plurality of fiber loops (3) which are formed by a reciprocating motion, and at least one anchoring winding (4) for securing said plurality of fibers loops (3) to said article (2) of manufacture, said anchoring winding being produced by winding anchoring fibers to form a turn simultaneously with said reciprocating loop forming motion so that each longitudinally extending fiber loop is looped around said turn of said anchoring winding for securing the connecting element (1) to the article (2) of manufacture.
Claim 3
Dependent Claim
39 words
The article of manufacture of claim 1, wherein said plurality of fiber loops are formed by at least one fiber strand which is doubled-up upon itself to form two fiber loop slings held in place by said anchoring winding.
Claim 4
Dependent Claim
20 words
The article of manufacture of claim 2, wherein said anchoring winding comprises at least one turn extending through both slings.
Claim 5
Dependent Claim
88 words
The article of manufacture of claim 2, wherein said longitudinally extending fiber loops comprise a plurality of endless loop belts each of which is doubled-up upon itself to form two of said slings by each loop belt, said doubled-up loops belts being nested one within the next to form a nesting assembly from which said slings protrude, said nesting assembly enclosing said connecting element with the slings extending alongside said article of manufacture, said anchoring winding comprising a plurality of turns extending through respective ones of said slings.
Claim 6
Dependent Claim
24 words
The article of manufacture of claim 4, wherein said slings are arranged in a stepped fashion along opposite sides of said article of manufacture.
Claim 7
Dependent Claim
15 words
The article of manufacture of claim 2, wherein said fiber strand is a fiber belt.
Claim 8
Independent Claim
112 words
A method for securing a connecting element to an end of an elongated article of manufacture having a longitudinal axis, comprising the following steps: (a) looping a first fiber around the connecting element and onto an end of said article so that the fiber forms at least one loop having four legs extending in parallel to said longitudinal axis to form two slings, and, (b) simultaneously winding at least one turn of an anchoring winding onto and around said article in such a position that said one turn extends through each sling to hold down a respective leg loop, (c) whereby the legs loops are turned around the respective anchoring winding turn.
Claim 9
Independent Claim
112 words
A method for securing a connecting element to an end of an elongated article of manufacture having a longitudinal axis, comprising the following steps: (a) looping a first fiber around the connecting element and onto an end of said article so that the fiber forms at least one loop having four legs extending in parallel to said longitudinal axis to form two slings, and, (b) simultaneously winding at least one turn of an anchoring winding onto and around said article in such a position that said one turn extends through each sling to hold down a respective leg loop, (c) whereby the legs loops are turned around the respective anchoring winding turn.
Claim 10
Dependent Claim
51 words
The method of claim 7, further comprising impregnating said fiber strand or belt and said anchoring winding with a suitable resin and curing the resin for bonding the fiber strand or belt and the winding turns of the anchoring winding to one another, to the connecting element and to the article.
