The object of the present invention is to provide an open-ended base fabric for a papermaking press felt. In the present invention the shape of the seam loops are retained to facilitate the mounting operation of the press felt. The open-ended base fabric of the present invention comprises a continuous MD thread in the MD direction disposed in each layer constituting both surfaces of the base fabric and CD threads in the CD direction interwoven with the MD thread to connect each layer. The continuous MD thread forms a loop portion for inserting a seam thread at both ends of the base fabric. The base fabric is provided with a control thread along each end edge of the CD thread arrangement. The control thread is interwoven in a different weave pattern from that of the CD thread in the base fabric. The control thread is seperately arranged for each layer of the MD thread, and urges the MD thread near both ends not to deviate in the outward direction and/or the CD direction so that the shape of the loop portion for inserting a seam thread is retained.
