1. Stencil frame for tensioning stencils of an angular shape comprising corner elements, edge elements, fastening elements and tensioning devices with a tensioning device being associated with each edge element;the corner elements each have two, mutually perpendicular, guiding profiles, the two guiding profiles being joined at an intersection of their axes;
the edge elements each have a uniaxial reception profile, each reception profile being connectable to two guiding profiles by loose fit;
each tensioning device has at least one elastic element;
each tensioning device connects between two neighboring corner elements and each tensioning device is connected to one edge element;
wherein a line of force exerted by each tensioning device is parallel to the axis of its corresponding reception profile, and optionally the line of force exerted by each tensioning device is uniaxial with the axis of its corresponding reception profile.
