2 Claims. (01. 206-57) My invention relates to the folding ofsheets of along the line 24 to complete thefoldedarticla material, such as paper, used for napkins, towels The sheet 4 B is preferably of-tissue paperor the and the like, and the same has for its object to like employed, for napkins and towels. The coproduce a sheet folded so as to facilitate the-reextensive sections {2 are preferably of prederl' moval thereof from a, stack of such folded sheets, termined dimensions so that the article will fit 6 particularly when the stack is disposed in a disthe d spe s ng devic The i s Of i 1 6,; pensingdevice. p, 20 and 22 are thereforesotalgen asto enable Another object of the'invention is to provide an formation of sections l2 of the desired size, the article of the character specified in which the po tion of the sheet "I int ed ate e fo ded 10 folds thereof are arranged to render the article d e p rti ns r pa s I a a d 14b f ming th 10 substantially uniformly resilient or flexible to sections l2,while the sections M are formed from facilitate the removal thereof from the stack.

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,

2. A folded paper article having single-thick ness edge parts reversely folded on lines adjacent and parallel to its side edges, and three coextensive part-s all of equal width intermediate between the edge parts and at least twice as wide as the edge parts and reversely folded on equispaced'lines parallel to the edges to bring the coextensive parts into overlapping relation with the edge portions extending inwardly therebetween, and the sheet, so folded and overlapping, folded together on a line parallel to the end edges, whereby all side edges are folded edges, all exposed raw edges are at the end of the article opposite the last named fold, and the exposed surfaces are the full width of the folded article.
