1. A forming fabric tape for a machine for producing or processing a fiber material web, the forming fabric tape comprising:
an upper fabric layer including upper longitudinal threads and upper transversal threads woven into the upper longitudinal threads; and
a lower fabric layer including lower longitudinal threads and lower transversal threads woven into the lower longitudinal threads,
wherein the upper fabric layer and the lower fabric layer are arranged on top of one another so that the upper fabric layer is oriented towards the fiber material web and the lower fabric layer is oriented away from the fiber material web,
wherein a first distance A1 between two directly adjacent lower longitudinal threads is greater than a second distance A2 between two directly adjacent lower longitudinal threads, and
wherein a difference between the first distance A1 and the second distance A2 is between 20% and 175% of a diameter of the upper longitudinal threads.
