Claim:
An open-ended base fabric for a papermaking press felt, comprising: a continuous MD thread disposed in the MD direction on each layer constituting both surfaces of said base fabric; and CD threads in the CD direction interwoven with the MD thread to connect said each layer, said continuous MD thread forming a loop portion for inserting a seam thread at both ends of the base fabric, wherein said base fabric is provided with a control thread along each end edge of the CD thread arrangement, said control thread being a fiber which is thinner than the CD thread and/or a fiber which is flattened as it is bent, and interwoven in a different weave pattern from that of the CD thread in the base fabric, and said control thread urges the MD threads near the ends of the base fabric not to deviate in the outward direction and/or the CD direction so that the shape of said loop portion for inserting a seam thread is retained.
