Abstract

A web laying machine has a laying carriage driven back-and-forth over the laying table in a web laying direction. The laying carriage includes a chassis, an upper part mounted on the chassis and movable transversely to the laying direction relative to the chassis and rotatable about a vertical axis. A sled, carrying a support mechanism for a web supply reel is arranged on the upper part, and has a first position and a second position spaced from the first position in a direction parallel to the laying direction. The sled is movable from the one to the other position by rotating the upper part through an angle of 180.degree. or by linearly displacing the sled relative to the upper part. A web guide mechanism extends transversely to the laying direction and is supported on the sled underneath the support mechanism for causing the web to hang from the sled at approximately the same location thereof independently from an unwinding direction of the supply reel and for causing a leading end of the web to be positioned in a web intake zone of a feed roll which is supported on the chassis and which is rotated as a function of the travelling speed of the carriage.
