Abstract: The device comprises a laying carriage (3) movable transverse to a delivery transport belt (1) and on the delivery transport belt, an upper carriage (18), and two nap transport belts (11, 21) for guiding the nap web over the upper carriage and the laying carriage in a delivery gap formed at the laying carriage, where the two sections of the both nap transport belts partially, parallely extend in an area between the upper carriage and the laying carriage for receiving the nap web between the sections. The sections of the nap transport belts are arranged to supporting rollers. The device comprises a laying carriage (3) movable transverse to a delivery transport belt (1) and on the delivery transport belt, an upper carriage (18), and two nap transport belts (11, 21) for guiding the nap web over the upper carriage and the laying carriage in a delivery gap formed at the laying carriage, where the two sections of the both nap transport belts partially, parallely extend in an area between the upper carriage and the laying carriage for receiving the nap web between the sections. The sections of the nap transport belts in the area between the upper carriage and the laying carriage are arranged to supporting rollers, which are arranged in a movable supporting carriage. The supporting carriage is parallely processible for direction of motion of the upper carriage and the laying carriage, and is processible along from rails or tubes (10a) by using rollers. The actuation of the supporting carriage is coupled with the actuation of the laying carriage or the upper carriage. A chain or a toothed belt is introduced at the supporting carriage and is guided over a driving toothed wheel and a deflection wheel connected to a motor. The driving toothed wheel is driven by a same shaft as a driving toothed wheel of the laying carriage or the upper carriage but has other circumference than the driving toothed wheel of the laying carriage or the upper carriage. The supporting carriage has an independent drive. The sections of the both nap transport belts arranged between the upper carriage and the laying carriage are guided through a gap between the two supporting roller, and possess an outlet height at the outlet from the supporting roller, where the outlet height differs itself from the inlet height in the supporting roller. The supporting rollers are arranged in a distance next to each other. The sections of the both nap transport belts pass through an intermediate space between the supporting rollers. The device is formed as a correlation laying device. The supporting carriage is arranged at a height with the upper carriage and the laying carriage and between the upper carriage and the laying carriage. The drive of the supporting carriage is designed, so that the supporting carriage synchronously moves with the upper carriage and the laying carriage and with a speed, which lies between the speed of the laying carriage and the speed of the upper carriage. The first nap transport belt at the upper carriage forms a band inlet with an obliquely downwardly inclined inlet path, is passed through the laying carriage and is parallely led back to the upper carriage as cover belt over the delivery transport belt. The second nap transport belt is only guided through a clamping carriage movable transverse to the delivery transport belt and through the upper carriage.
