Unique Features of the Draper Tab Tensioning System
All Draper tab tensioned screen surfaces are cut on CNC controlled cutting tables, including the tabs. The tabs are then folded to the backside of the screen surface and RF welded . The result is a much stronger tab, with no possibility of separation, as the tab and the surface are fused into a single layer of material. We cycled a tab tensioned screen made in this manner over 30,000 times with no tab failure.
This new system is not only better, it is much nicer looking. Making a tab tensioned surface in this manner significantly reduces the puckering that has characterized the edges of tab tensioned screens made by Draper and other screen manufacturers for years – please see unretouched photos below.
We believe this new system represents a unique and significant improvement in tab tensioned screen design. We are so confident of this new system that we warrant all Draper tab-tensioned screens against tab separation for five years from date of manufacture.
