Needle for Inserting a Wire Into a Tire
The needle ( 12 ) for inserting a wire into a tire has: a piercing zone ( 18 ) having an axis of symmetry, and a duct ( 30 ) having a proximal opening and a distal opening ( 36 ) opening into the zone ( 18 ) and off-centre relative to the axis, the duct consisting of the proximal opening and of a rectilinear profiled section including the distal opening.
1 . A needle for inserting a wire into a tire, comprising:
a piercing zone having an axis of symmetry; and
a duct having a proximal opening and a distal opening opening into the zone and off-centre relative to the axis, the duct consisting of the proximal opening and of a rectilinear profiled section including the distal opening.
2 . The needle according to claim 1 , wherein in which the distal opening extends entirely on one and the same side of the axis.
3 . The needle according to claim 1 , wherein the distal opening extends entirely at a distance from the axis.
4 . The needle according to claim 1 , wherein the duct has a duct axis that is inclined relative to the axis of symmetry of the zone.
5 . The needle according to claim 1 , wherein at least any one the piercing zone has an axi-symmetric face into which the distal opening opens entirely.
6 . The needle according to claim 1 , wherein the needle has a support zone into which the proximal opening opens while being concentric with the support zone.
7 . The needle according to claim 1 , made of metal or of metal alloy.
8 . The needle according to claim 1 , wherein the piercing zone has a greater hardness than that of another portion of the needle.
9 . A device for inserting a wire into a tire, comprising a needle according to claim 1 .
10 . A method for manufacturing a needle according to claim 1 , wherein the piercing zone is treated in order to increase the hardness thereof.
11 . A method for manufacturing a tire, wherein a wire is inserted into an element comprising rubber with a needle according to claim 1 .
