    • 771,712. Making wafer sandwiches. WOLF, P. July 4, 1955 [July 13, 1954], No. 19259/55. Class 28(1) Filled wafer strips are made by placing a layer of standard-size wafer sheets on a table or conveyer with the sheets abutting one another longitudinally and if desired transversely, spreading a layer of filling over the wafer sheets and then placing a further layer of wafer sheets on top so that the joints between separate wafer sheets in the upper layer do not coincide with the joints between wafer sheets in the lower layer. As shown, wafer sheets are deposited on to conveyer belt 1 and are fed, assisted by a feed roll 2, under a device 3 to receive a layer of filling. A layer of wafer sheets is placed on to the filling and the strip is then compressed by a roll 4. A second layer of filling may be deposited from device 5 on to the strip and a further layer of wafer sheets deposited on the filling, the joints between these wafer sheets being offset from the joints between those of the layer immediately beneath. A further roller 4 1 compresses the strip again. Further layers of filling and wafer sheets may be added as required. The finished strip is cut up.
