## Abstract

A gland packing provided in a fluid apparatus such as a pump and compressed in an axial direction so as to prevent penetration leakage of a fluid is provided. The gland packing has a packing base material 11 of a predetermined length including a band-like flat braid 12 braided by moving a plurality of yarns 13 along one track K. The band-like packing base material 11 is shaped into a ring by abutting longitudinal ends 12a and 12b of the packing base material 11 so that a width direction thereof is parallel with a packing axial direction, and is then compressed in the axial direction, whereby the packing base material 11 is overlappedly folded in a packing axial direction, with a longitudinal direction of the packing base material 11 as a direction of folding lines 14.

## Claims

### Claim 1

A gland packing comprising:
a packing base material of a predetermined length including a band-like flat braid braided by moving a plurality of yarns along one track,
wherein the packing base material is compressed and overlappedly folded in a width direction thereof.

### Claim 2 (depends on 1)

The gland packing according to claim 1, wherein the packing base material is shaped into a ring and is overlappedly folded in a packing axial direction, with a longitudinal direction thereof as a direction of folding lines.

### Claim 3 (depends on 2)

The gland packing according to claim 2, wherein the packing base material has at least two folding lines, and is overlappedly folded in its entirety.

### Claim 4

A packing set comprising:
a plurality of gland packings in a packing axial direction,
wherein the gland packing includes a packing base material of a predetermined length including a band-like flat braid braided by moving a plurality of yarns along one track, and
wherein the packing base material is compressed and overlappedly folded in a width direction thereof.

### Claim 5 (depends on 4)

The packing set according to claim 4, wherein abutted longitudinal ends of the packing base materials of a pair of gland packings adjacent to each other in an axial direction are apart from each other in the circumferential direction about the center line of the packings.
