PCT No. PCT/EP84/00144 Sec. 371 Date Jan. 15, 1985 Sec. 102(e) Date Jan. 15, 1985 PCT Filed May 15, 1984 PCT Pub. No. WO84/04517 PCT Pub. Date Nov. 22, 1984.A friction separator for separating letters and similar flat items from a stack of such items. The friction separator comprises a base belt for supporting the stack of items and conveying them in a first direction, a guide wall extending along one side of the belt and a removal member for withdrawing the foremost items in the stack through a gap between the guide wall and the removal member. A first support member is positioned in a plane defined by the leading edge of the stack at the trailing portion of the shortest item withdrawn by the removal member, the first support member supporting the stack at a point spaced from the guide wall by a distance which is less than the length of the shortest item to be processed. A second support member is positioned at a location between the plane and the trailing edge of the stack of items supported by the belt, and is further positioned at a distance from the guide wall which is less than the length of the longest item to be processed. Means are provided for resiliently pressing at least one of the first and second support members against the stack.
