Abstract
In order for a laying machine for laying out a fabric web comprising a fabric web guide mechanism for drawing the fabric web off a fabric reel and laying it out as a fabric layer, including a fabric feed device for feeding the fabric web in accordance with the speed of the laying machine, and also comprising a tension relief control means, to be designed as simply as possible from a structural point of view, it is proposed that the fabric web loop be arranged between the fabric feed device and the laid-out fabric layer, that the fabric web loop be formed by a bend of free-falling fabric web piece in a direction extending transversely to the direction of fall, and that the sensing barrier detect a change in the length of the arc of the bend through displacement of the freely hanging bend.
