ABSTRACT OF THE DISCLOSURE An improved device device, in the form of a rounded, substantially M-shaped vacuum bar, is provided for drawing curled sheet material into its rounded trough where a multiplicity of spaced vacuum openings are located thereby reversely bending the sheet and taking out the curl previously imparted to it. The bar is made of a reinforced plastic material with a hard and very smooth surface which wears well and does not scratch, mar or otherwise destruct the face of the sheet materials. A dispersion of fine carbon particles in the surface material of the bar is also effective to eliminate static electric charges built up in the sheet material incident to previous processing operations.
