## Abstract

A wire material accumulator is configured to accumulate a wire material. The wire material accumulator includes a plurality of fixed-side pulleys rotatably supported on a fixed axis part, and a plurality of movable-side pulleys rotatably supported on a movable axis part that is supported so as to be movable toward and away from the fixed axis part. The wire material accumulator further includes a drawing mechanism part that applies a drawing force to a wire material W in the middle of the wire material being wrapped from any one to another of the plurality of fixed-side pulleys and the plurality of movable-side pulleys.

## Claims

### Claim 1

A wire material accumulator configured to accumulate a wire material, said wire material accumulator comprising:
a plurality of fixed-side pulleys rotatably supported on a fixed axis part;
a plurality of movable-side pulleys rotatably supported on a movable axis part that is supported so as to be movable toward and away from said fixed axis part; and
a drawing mechanism part that applies a drawing force to a wire material in the middle of said wire material being wrapped from any one to another of said plurality of fixed-side pulleys and said plurality of movable-side pulleys.

### Claim 2 (depends on 1)

The wire material accumulator according to claim 1, wherein
said drawing mechanism part includes a drawing pulley around which said wire material can be wrapped and a rotary drive part that drives said drawing pulley in rotation, said drawing pulley being arranged in such a position that the wire material can be wrapped around said drawing pulley in the middle of being wrapped from any one to another of said plurality of fixed-side pulleys and said plurality of movable-side pulleys.

### Claim 3 (depends on 2)

The wire material accumulator according to claim 2, wherein
said drawing pulley is provided at the side opposite to said movable-side pulleys across said fixed-side pulleys.

### Claim 4 (depends on 3)

The wire material accumulator according to claim 3, wherein
the diameter of said drawing pulley is larger than the diameter of said fixed-side pulley.

### Claim 5 (depends on 2)

The wire material accumulator according to claim 2, wherein
said drawing pulley is provided in such a position that one extension portion of the wire material wrapped around said drawing pulley can be guided by any of said plurality of fixed-side pulleys and wrapped around any of said plurality of movable-side pulleys while the other extension portion of the wire material wrapped around said drawing pulley can be wrapped around any of said plurality of movable-side pulleys without a contact with said plurality of fixed-side pulleys.

### Claim 6 (depends on 1)

The wire material accumulator according to claim 1, wherein
said drawing mechanism part comprises a plurality of drawing mechanism parts.

### Claim 7 (depends on 6)

The wire material accumulator according to claim 6, wherein
said plurality of drawing mechanism parts are provided so as to be shifted from one another in a direction of movement of said movable axis part.

### Claim 8 (depends on 6)

The wire material accumulator according to claim 6, wherein
said plurality of drawing mechanism parts are provided so as to be shifted from one another in a direction crossing both an axis of said fixed axis part and a direction of movement of said movable axis part.
