Abstract

1402961 Feeding sheets MERKUR BETEILIGUNGS-GmbH [trading as WEITMANN & KONRAD] 11 Jan 1973 [21 Jan 1972] 1553/73 Heading B8R Sheets are fed from the top of a pile 100, Fig. 1, by means of rollers 102, 103 and a belt 105 against a pivoted registering front stop 109, and thereafter to a printing-machine, and the presence or absence of sheets at the registering position is detected by two laterally spaced light-sensing means 110, which actuate control means to stop the printing machine and sheet feed, or to start or stop printing by bringing cylinders 107, 108 together or apart, according to the presence or absence of a sheet at particular times, the sheets being fed in overlapping relationship. During each machine cycle, the sensing means are enabled to actuate the control means at three specific moments A, B, C, corresponding to early, correct and late arrival of a sheet at the registering position. Two discs are mounted on a shaft 116, Fig. 3a, rotating in synchronism with the machine, the discs carrying cams 112, 113 which pass switches 117, 118 and inductively influence the latter at moments A, B, C. The electric control circuit, (Figs. 5a and 5b, not shown) includes a storage means which is set in one of two states, according to whether the printing-machine is being operated normally, or is being started (i.e. the first sheet has not yet reached the registering position). During normal operation, detection of a sheet at moment B causes printing to take place. If the sheet is askew, it is detected by only one of the two sensing means and the machine is stopped. If there is no sheet present at moment B, the machine is stopped. During starting, if a sheet is detected at moments A or C, or is detected askew, the machine is stopped, but detection of the absence of a sheet at moment B does not stop the machine.
