Abstract

A web laying machine for laying a web in superposed layers on a laying table has a laying carriage traveling back and forth along the length of the laying table between first and second end position, a web laying unit vertically displaceably mounted on the laying carriage and a web holding unit arranged at the first end position for immobilizing the web while the laying carriage moves from the first end position to the second end position. The web laying unit is maintained, during at least the greatest part of the travel of the laying carriage between the two end positions, at a laying height above the laying table. The laying height is at a higher level than the height position of the web laying unit while the laying carriage is in the first end position. Further, the web laying unit is lowered at least approximately to the level of the precedingly deposited web layer or, in the absence thereof, to the level of the laying table, at the latest when the laying carriage reaches the web holding unit.
