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 the upper longitudinal threads are offset from each other unevenly,
wherein the upper longitudinal threads are arranged so that average distances of the upper longitudinal threads have the following sequence which is repeated continuously in a transversal direction of the fabric tape: first large distance, first large distance, and second small distance, and
wherein a difference between an average first large distance and an average second small distance is at least 50% of a diameter of an upper longitudinal thread.
