Abstract
A device for placing a cylindrical screen provided with end rings in, and removing it from, a rotary screen printing machine comprises a screen support and lifting means connected to the screen support, for moving the screen support up and down. The screen support is designed to support the cylindrical screen while it is moving up and down. The screen support is provided with guide means, for example guide bars, along which the cylindrical screen can be moved in its lengthwise direction. With the aid of the device, cylindrical screens can be placed in, and removed from, the screen printing machine in a simple way, with the minimum chance of damage to the screens.
