Abstract: A screen printing apparatus utilizes a number of screen printing heads disposed along a transport path for the fabric; each of the heads moves upwardly on a respective carrier so as to be tiltable by a pneumatic cylinder with respect to the carrier which is vertically displaceable in common with the other carriers by the displacement of a common element connecting wedges together. The carriers each have extensions provided with rollers which ride upon ramp surfaces of the respective wedges. The vertical displacement compensates for changes in diameter of the screen printing patterns and for changes in thicknesses of the webs processed.
