In a method for treating a yarn by needling, with the yarn fibers being drawn transversally to the longitudinal direction of the yarn, it is proposed that fibers of a yarn formed from staple fibers are needled in a brush support before the yarn is removed from the brush support. A variable resistance output dependent upon the position of the arm controls the speed of rotation of heated rollers in the lamination machine so that the layered sheet material will be drawn through the machine with variable speed to better infuse thermal adhesive into the material should such material be detected. When the switch is triggered, the switch transmits a switch signal to the control unit, and the control unit, according to the operating signal, transmits an adjusting signal to the processor of the extension base in response to the switch signal via the first wireless transceiver unit and the second wireless transceiver unit.
