in the same plane however in this case the adjacent top plates 4 still contact each other even though there is no step therebetween due to there being no overlap consequently there is still no space between the top plates 4 if the overlapped portions of the top plates 4 remained when the backing strip 2 is rolled on the periphery of roller r the adjacent top plates 4 form steps but there is no space between the top plates 4 thin felt cover f is rolled on the spring pad 1 the claws 4 a of the upper surface of the top plate 4 catch the inside or lower surface of the felt cover f the entire lower surface of the felt cover f thus contacts the whole upper surface of the top plates 4 thus no marks are made on the surface of felt cover f because the felt cover f is elastically supported by the spring pad 1 and because there is no space between the adjacent top plates 4 when the sheet ironing machine p is used the heated surface of bed q is heated by the heat source and the roller r is rotated to stick or draw the item to be ironed between the pressing surfaces of the bed q and.
