1,201,525. Delivering sheets. FERAG, FEHR & REIST A.G. 24 May, 1968 [26 May, 1967], No. 24893/68. Heading B8R. Photoelectric cell 13 detects any break in the imbricated stream of articles 5 (e.g. newspapers) being transferred from conveyer 2 to conveyer 1, and causes the drive to conveyer 1 to be interrupted until the first article 10 of the trailing portion overlaps the last article 8 of the leading portion. The drive to conveyer 1 may be by way of electromagnetic coupling 3 which is re-engaged a predetermined time after the article 10 interrupts the beam 6. A mechanical feeler may replace the light barrier 6.
