Abstract
A paper machine forming screen has a paper side and a machine side. A plurality of synthetic longitudinally extending machine direction threads are provided. A plurality of synthetic cross threads extend generally transverse to the machine direction threads, and the cross threads are disposed in first and second groups and at least of the cross threads have a flattened cross section. The first group threads are disposed in a plane of the paper side and have a repeat floating over a number of the machine direction threads. The second group threads form a plane on the machine side. The flattened cross threads extend parallel to the paper side plane, a distance from about 1.2 to about 2.2 times the distance by which the flattened cross threads extend transverse to the paper side plane.
