Abstract
A cable bead comprising an annular core and a side wire spirally wrapped up around the annular core, wherein the annular core is made up of a round steel wire made to circle once or made, without being stranded, to circle 2 to 10 times side by side, and wherein the side wire is a round steel wire consecutive from the annular core. This provides a high-strength cable bead that can press a tire main body against a wheel without fail even if a tire is charged with a high load.
Claims16
A cable bead comprising:
- an annular core;
- and
- a side wire spirally wrapped up around the annular core,
- wherein the annular core is made up of a round steel wire made to circle once or made, without being stranded, to circle 2 to 10 times side by side, and
- wherein the side wire is a round steel wire consecutive from the annular core.
2 more elements
A cable bead manufacturing method comprising:
- an annular core formation process of forming an annular core by making a round steel wire circle once or by making it, without stranding it, circle 2 to 10 times side by side;
- and
- a side wire wrapping process of spirally wrapping up a round steel wire consecutive from the annular core around the annular core without cutting it.
A cable bead manufacturing device comprising:
- an annular core formation mechanism of forming an annular core by making a round steel wire circle once or by making it, without stranding it, circle 2 to 10 times side by side;
- and
- a side wire wrapping mechanism of spirally wrapping up a round steel wire consecutive from the annular core around the annular core without cutting it,
- wherein the annular core formation mechanism has an annular core turning mechanism of turning the annular core in a circumferential direction,
- wherein the side wire wrapping mechanism has
- a first cassette movement mechanism of moving a cassette accommodating a round steel wire between outside and inside a ring of the annular core, and
- a second cassette movement mechanism of moving the cassette inside a ring of the annular core from one side of a turning axis of the annular core to another side thereof and moving the cassette outside a ring of the annular core from another side of a turning axis of the annular core to one side thereof, and is a mechanism of moving the cassette between inside and outside a ring of the annular core turning in a circumferential direction, and spirally wrapping up, around the annular core, a round steel wire drawn out of the cassette,
- wherein the annular core turning mechanism has a driving source, a pinch roller portion, and a marking mechanism,
- wherein the pinch roller portion has a driving roller provided to either one side of, inside or outside a ring of the annular core and rotated by driving force out of the driving source, a driven roller rotatably provided to either another side of, inside or outside a ring of the annular core, a pinch roller turning the annular core forward/reversely, and a rotary encoder attached to the pinch roller or the driven roller in order to measure in length a round steel wire to be made to circle as the annular core,
- and wherein the marking mechanism is that of marking, when a measurement value of the length reaches a predetermined value, a surface of a round steel wire being at a site where such a value is reached.

A cable bead manufacturing device comprising:
- an annular core formation mechanism of forming an annular core by making a round steel wire circle once or by making it, without stranding it, circle 2 to 10 times side by side;
- and
- a side wire wrapping mechanism of spirally wrapping up a round steel wire consecutive from the annular core around the annular core without cutting it,
- wherein the annular core formation mechanism has an annular core turning mechanism of turning the annular core in a circumferential direction,
- wherein the side wire wrapping mechanism has
- a round steel wire supply unit to supply a round steel wire wrapped up around a reel to a wrapping portion of the annular core,
- a slide unit to move the reel of the round steel wire supply unit in parallel to a turning plane of the annular core from outside the annular core toward inside it, move it perpendicularly through inside a ring of the annular core from one side of the annular core to another side thereof, move it in parallel to a turning plane of the annular core from inside the annular core to outside it, and move it perpendicularly from the other side of the annular core to a starting position on the one side thereof to return it thereto,
- wherein the annular core turning mechanism comprises:
- a pinch roller provided in a vicinity of a top portion of the annular core and turning the annular core forward/reversely;
- a loose roller provided in a vicinity of a bottom portion of the annular core and guiding the annular core;
- a rotary encoder attached to the pinch roller or a driven roller in order to measure in length a round steel wire to be made to circle as the annular core;
- and
- a marking mechanism of marking, when a measurement value according to the rotary encoder reaches a predetermined value, a surface of a round steel wire being at a position where such a value is reached, and
- wherein the round steel wire supply unit has two reel receipt and delivery mechanisms facing each other while interposing a turning plane of the annular core therebetween,
- is configured to rotatably accommodate the reel in a cassette being a little larger in diameter than the reel in outer diameter and simultaneously having a cylindrical outer circumferential wall substantially equal in inner width to the reel and to draw out a round steel wire through a drawing hole provided to an outer circumferential wall of the cassette, and
- is provided to two locations lying symmetrically with respect to a turning axis of the annular core.
