A device for producing net-like scrims with intersecting longitudinal threads (3, 3a, 3b) and cross threads which define a first direction (longitudinal direction) and a second direction (transverse direction) extending transversely to the first direction and hence a thread deposition plane, the device comprising: - at least one rotor arm which comprises a cross thread deposition element for depositing a cross thread to be supplied in transverse direction, - means for depositing longitudinal threads (3, 3a, 3b) to be supplied in longitudinal direction, - two cross thread deposition worms rotatably aligned in longitudinal direction with windings to receive cross thread loops of a cross thread supplied via the at least one rotor arm, wherein a rotation of a cross thread deposition worm provides for a feed of cross thread loops received in its windings in longitudinal direction towards a free end of this cross thread deposition worm and there for a deposition of the cross thread loop in the thread deposition plane, characterized in that in the region of one free end of each of the cross thread deposition worms at least one auxiliary device is provided to control the deposition of the cross thread deposition loops released by the cross thread deposition worms in the thread deposition plane, said at least one auxiliary device comprising: two endless belt pairs each arranged in longitudinal direction of the thread deposition plane at its left and right edge, wherein per left and per right endless belt pair an upper and an associated lower endless belt each can be aligned relative to the thread laying plane such that the upper endless belt can be guided from above the thread deposition plane and the lower endless belt from below the thread deposition plane towards cross thread loops of a cross thread to be guided in the cross thread deposition worms such that the cross thread loops can be frictionally enclosed between the upper and the lower endless belt, wherein means are provided to drive the endless belts (30, 31) of each endless belt pair in the thread deposition plane in longitudinal direction, so that a cross thread deposition loop enclosed between a pair of endless belts (30, 31) in the thread deposition plane can be moved on by the endless belts (30, 31) in longitudinal direction. - at least one rotor arm which comprises a cross thread deposition element for depositing a cross thread to be supplied in transverse direction, - means for depositing longitudinal threads (3, 3a, 3b) to be supplied in longitudinal direction, - two cross thread deposition worms rotatably aligned in longitudinal direction with windings to receive cross thread loops of a cross thread supplied via the at least one rotor arm, wherein a rotation of a cross thread deposition worm provides for a feed of cross thread loops received in its windings in longitudinal direction towards a free end of this cross thread deposition worm and there for a deposition of the cross thread loop in the thread deposition plane, two endless belt pairs each arranged in longitudinal direction of the thread deposition plane at its left and right edge, wherein per left and per right endless belt pair an upper and an associated lower endless belt each can be aligned relative to the thread laying plane such that the upper endless belt can be guided from above the thread deposition plane and the lower endless belt from below the thread deposition plane towards cross thread loops of a cross thread to be guided in the cross thread deposition worms such that the cross thread loops can be frictionally enclosed between the upper and the lower endless belt, wherein means are provided to drive the endless belts (30, 31) of each endless belt pair in the thread deposition plane in longitudinal direction, so that a cross thread deposition loop enclosed between a pair of endless belts (30, 31) in the thread deposition plane can be moved on by the endless belts (30, 31) in longitudinal direction.
