Abstract
In order to deposit a web (13) onto a conveyer (2) of a table (1) with one edge aligned with a datum position, a carrier (9) is provided which is rotatable with respect to the table (1) and has an auxiliary conveyer (10). Rotation of the carrier (9) takes place in response to deviation of the actual position of the edge from the datum position, which is detected at the point of deposit of the web (13) onto the conveyer (2) by a suitable position detecting sensor (21). For rotating the carrier (9), a motor (20), whose direction of rotation and angle of rotation can be controlled, is used. The apparatus can be used, in particular, for depositing webs of fabric removed from bolts (4) onto a laying table for cutting purposes.
