Abstract: 907,300. Addressing-machines. ADDRESSOGRAPH-MULTIGRAPH Ltd. Sept. 9, 1960 [June 10, 1959], No. 19897/59. Class 100 (2). In a machine for manufacturing addressed wrappers 12 for use in sending magazines &c. by post, the machine being arranged to feed paper from a reel 14 through an addressing position 3 where addresses 42 are printed on the paper periodically and one at a time, an adhesive tear-off tape 58 is applied to the paper along the length thereof as it passes through the machine and a guillotine 40 is provided for chopping the addressed paper having the tape stuck thereto, into required wrapper lengths, each such length having an address thereon. The apparatus shown comprises an address or like series printing machine 2 of the kind described in Specification 558,793 in combination with a paper reel support and feed attachment 13 and a mechanism 25 which houses a second printing device 32, a wrapper perforating drum 72, drive means for intermittently progressing the paper through the apparatus, reel feed means for applying the tape 58 to the paper, the guillotine 40 and a delivery tray 78. The paper feed to the machine 2 comprises a spring- loaded lever, roller and brake mechanism 21, 22, 22A, 23, 24 which allows paper feed, in response to a drive movement from the drive means, through a longitudinal tensioning of the paper which swings the spring-loaded roller 22 upwardly to release the reel brake mechanism 23, 24. The second printing device 32 is used to apply the sender's impression 43 to each wrapper 12 and the mechanism 25 is adjustably attached to the machine 2 through hand-wheel operated rack-and-pinion devices 28, 29, 30, 31 and a bar and releasable fastening means 27, 26 to allow, through bodily adjustment of the mechanism 25 relative to the machine 2, adjustment of the location of the impression 43 on the wrapper. The intermittent drive means comprises an electric motor driving through a clutch-electrically operated in timed relation to the printing cycle of the machine 2-drive rollers 33 and 37 and a shaft 49 carrying an adjustable throw crank 48 pivotally mounting a rack 45 in mesh with a gear-wheel 44 arranged to intermittently drive, through a gear train (not shown) and a free wheel device, upper wheels 38 of three pairs of co-operating wheels 38, 39. Adjustment in the length of wrappers to be produced may be effected by altering the throw of the crank 48. The centre wheel pair 38, 39 applies the tear-off tape 58 to the now printed paper the upper wheel feeding it from a reel 59 whilst the lower wheel 39 pivotally mounts a spring-loaded lever 75 carrying the perforated drum 72 which co-operates with a slotted plate 74 to apply perforations 76, 77 to the moving paper. The tape is fed from the reel through a spring-loaded lever, roller and brake mechanism 65-71 such that on a tensioning of the tape deriving from a drive movement of the wheels 38 the levers 65 carrying the roller 66 are swung downwardly to withdraw the spring-biased brake 68 from the reel shaft 60. Between the drive rollers 33 and 37 the paper passes over a vertically adjustable idler roller 36 alteration of the height of which displaces the position of the impression 43 and address 42 on each wrapper 12 along the length of the wrapper.
