The overlapping panels arethen folded The folded article as described is inherently 55 resilient or flexible so that the forward edge portion 26 can be uniformly flexed for facilitating the removal thereof from the stack or dispensing device such as disclosed in my copending application Serial No. 459,920 filed June 9, 1930. The opposite outside surfaces of the folded article are formed from the front side of the sheet while the opposirg' or contacting innermost surfaces are formedfrom the rear side of the sheet, said outside and innermost surfaces being coextensive and continuous and no raw edges being exposed so that the article can be readily removed from the stack without danger of tearing or otherwise injuringthe same. By my invention I am able to apply a flexing pressure to the folded article at the uppermost side thereof, relative movement of the innermost relatively smooth coextensive surfaces, brought into contact by folding at 24,

being facilitated, resulting in the flexing of the,
