Abstract
There is provided a papermaking felt comprising a base fabric layer and at least one batt layer integrated with the base fabric layer, wherein the base fabric comprises at least one layer formed by spirally winding a band-shaped body having a width smaller than a width of the papermaking felt and having a plurality of ground warp yarns, a plurality of ground weft yarns, a first side edge, and a second side edge in such a manner that the first side edge and the second side edge are adjacent and thereby joining the side edges together; and a plurality of marks is arranged at regular intervals in a warp direction of the band-shaped body.

A method for producing a papermaking felt,
- the felt comprising
- a base fabric layer including at least one layer formed by spirally winding a band-shaped body having a width smaller than a width of the papermaking felt and having a plurality of ground warp yarns, a plurality of ground weft yarns, a first side edge, and a second side edge in such a manner that the first side edge and the second side edge are adjacent and thereby joining the side edges together, wherein a plurality of marks is arranged at regular intervals in a warp direction of the band-shaped body, and
- at least one batt layer integrated with the base fabric layer,
- the method comprising:
- arranging the marks of the band-shaped body, which are adjacent in the width direction of the band-shaped body, at regular intervals in the warp direction of the band-shaped body or in a straight line in a width direction of the band-shaped body.
A method for producing a papermaking felt, comprising:
- providing a band-shaped body having a width smaller than a width of the papermaking felt and having a plurality of ground warp yarns, a plurality of ground weft yarns, a first side edge, and a second side edge wherein a plurality of marks is arranged at regular intervals in a warp direction of the band-shaped body, and
- spirally winding the band-shaped body in such a manner that the first side edge and the second side edge are adjacent and that the marks of adjacent parts of the band-shaped body are arranged at regular intervals in the warp direction of the band-shaped body or in a straight line in a width direction of the band-shaped body, and thereby joining the adjacent first and second side edges together.
