Abstract: 383,844. Printing- machines. ADREMA MASCHINENBAUGES., 62, Alt Moabit, Berlin. March 14, 1932, No. 7574. Convention date, March 12,1931. [Classes 100 (i) and 100 (ii).] Addressing and like machines; rotary machines. -In a machine for printing constant matter in conjunction with changing addresses &c., the former is printed by a rotary couple and the latter by means of flat printing- plates fed in succession into printing relation with the impression cylinder of the rotary couple. In one construction, the constant matter is printed by a segment 1, Fig. 1, coacting with an impression segment 4, and the variable matter by means of address plates 13 fed between the segment 4 and a roller 10. An auxiliary printing-roller 36 prints a signature &c. The segment 1 is provided with peripheral or axial grooves to receive types, and the embossed characters on the plates 13 are arranged across or lengthwise to correspond. The plates 13 are extracted from a magazine 14 by a pusher 15 reciprocated by a rod 23 connected to a chain 24 driven from the segment 4, and are advanced in stages by pawls on one of a pair of bars fixed to the pusher ; the plate in printing position is inked by a ribbon 22 mounted on a reciprocating carriage secured to the bars. Sheets 32 are fed into grippers on the segment 4 and are delivered at 31. In a second construction, the plates 13, Fig. 5, are fed by lugs 65 on an endless chain 61 driven by a wheel 60 fixed to a pinion 58 engaging a pinion 57 on a main shaft 55, an inkribbon carriage 76 mounted on guide-rods 77 is reciprocated by a rod 74 connected to a bell crank 72 oscillated by a cam 66 on the shaft 55, and the segment 4 is rotated by a chain 50 driven by a wheel 51 fixed to a shaft in line with the shaft 55 and coupled thereto by bolts passed through slots in the cam 66 and an adjacent and normally coincident cam. The position of the addresses on the printed form may be varied by relative angular adjustment of the cams together with adjustment of the impression surface as described below; the cam adjustment does not affect the timing of the forward stroke of the carriage 76, although the return stroke is faster than before. Impression surfaces.-The roller 4 is provided with a detachable rubber-faced metal segment in line with the address-plate track, and when the address position is to be varied. as described above, this is replaced by a short segment 80, Fig. 8, fixed in either of three positions by a bolt 82 passed through either of three holes 81 .. 81<11>; the holes may, however, be merged into a peripheral slot thus providing further adjustments. Printing-surfaces. - The printing-surface of the segment 1, Figs. 5 and 8, consists of a series of flexible embossed strips 38 made of zinc or aluminium and arranged side by side. Each strip is provided with apertures engaging bevelled studs on clips 39, 41 hooked over the ends of the segments, which are bevelled so that the studs do not project beyond the periphery of the segment. The strips are tensioned by means of screws 43 on the clips 41. A pin at one end of the strip corresponding to the address column engages a hole in the segment, and a pin at the other end engages a peripheral slot ; similar pins on the other strips engage axial slots at each end to allow the strips to be adjusted axially whereby the spacing of the printed matter may be varied. Delivery apparatus. - The leading edge of each printed sheet is stripped off the segment 4 by radial pins 85, Fig. 8, carried by arms 89 fixed to a shaft 84 carrying the usual grippers 83. The pins 85 are pushed outwardly when the grippers are opened to release the sheet, by a cam 87 actuating a roller arm 86 fixed to the shaft 84.
