Abstract
Abstract A machine for producing a textile product, the machine having a needle provided with a leading end portion which extends non-axially with respect to the main portion of the needle, means for reciprocating the needle, in a predetermined needle reciprocation stroke, into and out of backing material and for effecting relative traversing movement therebetween, and means for ensuring that the leading end portion is inclined away from the direction of the said relative traversing movement throughout the latter, the said leading end portion having an axial length at least as great at the length of the needle reciprocation stroke.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
A machine for producing a textile product, the machine having a needle provided with a leading end portion which extends non-axially with respect to the main portion of the needle, means for reciprocating the needle, in a predetermined needle reciprocation stroke, into and out of backing material and for effecting relative traversing movement therebetween, and means for ensuring that the leading end portion is inclined away from the direction of the said relative traversing movement throughout the latter, the said leading end portion having an axial length at least as great as the length of the needle reciprocation stroke.
Claim 2
Dependent Claim
99 words
A machine for producing a textile product, the machine having a needle provided with a leading end portion which extends non-axially with respect to the main portion of the needle, means for reciprocating the needle, in a predetermined needle reciprocation stroke, into and out of backing material and for effecting relative traversing movement therebetween, and means for ensuring that the leading end portion is inclined away from the direction of the said relative traversing movement throughout the latter, the said leading end portion having an axial length at least as great as the length of the needle reciprocation stroke.
Claim 3
Dependent Claim
50 words
A machine as claimed in claim 1 which there are means for rotating the needle, whenever the said direction is changed, to ensure that the leading end portion is always inclined away from the said direction and that the needle tip always faces forwardly with respect to the said direction.
Claim 4
Dependent Claim
43 words
A machine as claimed in claim 1 in which the needle is a hollow needle having at its leading end an orifice through which textile material, which has been passed through the interior of the needle, may be introduced into the backing material.
Claim 5
Dependent Claim
43 words
A machine as claimed in claim 3 in which the axial length of the leading end portion is at least as great as the sum of the axial length of the said orifice and the bore of the needle at the said orifice.
Claim 6
Dependent Claim
31 words
A machine as claimed in claim 3 in which the axial length of the leading end portion is at least twice as great as the axial length of the said orifice.
Claim 7
Dependent Claim
39 words
A machine as claimed in claim 3 in which the orifice is always disposed in a plane which is disposed at an angle not exceeding 15° to a plane containing the axis of the main portion of the needle.
Claim 8
Dependent Claim
33 words
A machine as claimed in claim 1 in which the needle has a substantially constant internal cross-section normal to its longitudinal centre line at least throughout the length of the leading end portion.
Claim 9
Dependent Claim
32 words
A machine as claimed in claim 1 in which the leading end and main portions of the needle are linear and the included angle therebetween is in the range 5° to 15°.
Claim 10
Dependent Claim
22 words
A machine as claimed in claim 1 in which the main portion of the needle is mounted eccentrically in a rotatable carrier.
Claim 11
Dependent Claim
30 words
A machine as claimed in claim 1 in which the needle is mounted in a head and is withdrawn wholly into the latter at one end of its reciprocating stroke.
Claim 12
Dependent Claim
44 words
A machine as claimed in claim 10 in which the head has a recess within which is mounted a rotatable bush having an external surface which merges into that of the head, the bush having a slot through which the needle can be reciprocated.
Claim 13
Dependent Claim
28 words
A machine as claimed in claim 11 in which, by reason of engagement between the needle and the bush, rotation of the needle effects rotation of the bush.
Claim 14
Dependent Claim
28 words
A machine as claimed in claim 11 in which there is a drive connection between the means for rotating the needle and the bush to rotate the latter.
Claim 15
Dependent Claim
28 words
A machine as claimed in claims 3 in which there are means for passing a fluid through the interior of the needle to entrain the textile material therethrough.
