Abstract: 717,105. Wrapping newspapers &c. POPE, D. H. Oct. 27, 1952 [Nov. 30, 1951], No. 26870/52. Class 94 (1) A machine for rolling and wrapping newspapers and like articles comprises four tubular rolling spindles 18 mounted in bearings 16, 17 in a carrier 12, secured to an intermittentlyrotating main shaft 11, and fitted with pinions 19 meshing with a stationary gear 20 whereby each spindle is rotated during each 90 degrees movement of the shaft. Each spindle is formed with a longitudinal slot 21 extending from its free end and encloses a rotatable locking tube 22 formed with a corresponding slot 23 and urged by a torsion spring 26 to a position in which the slots are out of alignment, a pin 25 secured to the tube 22 and extending through a slot in the tube 18 being provided for aligning the slots. The carrier 12 also supports for shafts 30 on which are rotatably mounted L-section bearer plates 31 acted on by springs 32 secured to pins 33 on a collar 34 secured to the shaft 11, one arm of each plate being formed with a lug 35 coacting with a fixed cam 29, and the other arm supporting a shaft 36 carrying three spring clips 37 adapted to embrace the associated spindle 18. The shaft is fitted with a pair of lever arms 38 carrying a roller 39 which coacts with a rod 40 extending radially from the associated shaft 30, whereby if the plate is rotated clockwise the movement of spring clips is augmented. As the carrier comes to rest with a spindle in the righthand position, a cam 45 acts through linkage 47- 50 to rock a lever 51 carrying a pin 52 arranged to engage the pin 25 and bring the slots 21, 23 into alignment, and a folded newspaper. is fed by a conveyer belt 42 over a guide 44 so that its folded end 'enters the slots. The pin 25 is then released so that the tube 22 locks the end of the newspaper in the spindle and the carrier moves to carry the spindle to the upper position and cause rotation thereof. The lug 35 of the associated plate 31 rides off the cam 29 so that the plate and spring clips are urged towards the spindle and bear against the newspaper as it is rolled up. A wrapper is then fed through a chute 56 and curved guide 57 so that it enters between the free end of the newspaper, which rests on a spring-loaded plate 54, and the rolled portions thereof, and as the spindle is moved to the left-hand position the newspaper is completely rolled, thus enclosing the end of the wrapper and the wrapper is passed, preferably twice, therearound. The guide 57 is carried by lever arms 58 which are oscillated by a rod 59 to move the guide clear of the spindle as it approaches and leaves the upper position. Gum is then applied to the free end of the wrapper resting on a table 60 by a pad 61 carried by rocking arms 62, and as the spindle moves to the lower position the gummed end is pressed against the underlying portion of the wrapper by a spring-loaded plate 63. As the spindle comes to rest between teeth on an ejector 64 rotatable and slidable on a fixed shaft 65, the cam 29 swings the plate 31 and spring clips away from the spindle, a link 53 operates a rocking lever similar to the lever 51 to bring the slots 21, 23 into .alignment and the ejector is moved along the shaft 65 by linkage 66, 67 to strip the rolled and wrapped newspaper from the spindle.
