Abstract
The cross lapper for forming a nonwoven fabric from a fiber web includes in its infeed area a smooth cover belt or an array of linear elements spaced a certain distance apart and arranged parallel to each other to cover the fiber web being carried along on the upper run of a first web conveyor belt. The first end section of the cover belt or of the array of linear elements is connected to the upper carriage of the cross lapper. During operation of the cross lapper the fiber web moves along the bottom surface of a cover section of the cover belt or of the array of linear elements. The cross lapper comprises a compensating mechanism to compensate for the changes in the length of the cover section which occur as the upper carriage moves transversely back and forth.
