(under subclass 3.18) Subject matter wherein one of the sheet carrying means consisting of two elements each of which elements has an endless orbitally-moving surface rotating in opposite directions, the surface of one element being opposite to and spaced from the surface of the other element during at least a portion of their movement and the surfaces moving in the same direction and engaging opposite surfaces of the sheet lying therebetween during the portion of their movement.
(1) Note. The element may be an endless belt cooperating with another endless belt, a rotating roller cooperating with
another rotating roller or the endless belt cooperating with one or more rotating rollers; the criterion for placement herein being only that the conveyed sheet lies between the elements which thereby cooperates to move the sheet.
