Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
202 words
A needle for embedding within the body of a tufting machine needle module comprising a generally flat elongated element having a point at one end thereof and a yarn receiving eye adjacent said point, said element having a width greater than its thickness, said eye comprising an aperture extending transversely through the surfaces defining the thickness, a first region on non-uniform cross-sectional form within that longitudinal extent of the needle remote from the point intended for location within the body of the module, said first region comprising a localized region of increased width and reduced thickness relative to the transverse dimensions of an adjacent part of the elongate element, a pick-up area adjacent the eye, and a second region having, in at least one direction, a locating means defined by a predetermined transverse dimension intermediate the first region and the said pick-up area, said first and second regions lying substantially in the same plane, the said element being twisted intermediate the second region and the pick-up area to provide a set whereby that part of the element which provides the pick-up area lies in a plane inclined at a small acute angle relative to the plane of the first and second regions.
Claim 2
Dependent Claim
202 words
A needle for embedding within the body of a tufting machine needle module comprising a generally flat elongated element having a point at one end thereof and a yarn receiving eye adjacent said point, said element having a width greater than its thickness, said eye comprising an aperture extending transversely through the surfaces defining the thickness, a first region on non-uniform cross-sectional form within that longitudinal extent of the needle remote from the point intended for location within the body of the module, said first region comprising a localized region of increased width and reduced thickness relative to the transverse dimensions of an adjacent part of the elongate element, a pick-up area adjacent the eye, and a second region having, in at least one direction, a locating means defined by a predetermined transverse dimension intermediate the first region and the said pick-up area, said first and second regions lying substantially in the same plane, the said element being twisted intermediate the second region and the pick-up area to provide a set whereby that part of the element which provides the pick-up area lies in a plane inclined at a small acute angle relative to the plane of the first and second regions.
Claim 3
Dependent Claim
36 words
A needle as recited in claim 1, wherein that part of the element which provides the pick-up area lies in a plane inclined at an angle approximately 6° with respect to the first and second regions.
