  • Threaded portion 86 at the end of shaft 82 is engaged by nut 87 to lock shaft 82 in its adjusted "angular position.
  • Crank 87 operates nut 86.
  • glue device 15 When gluedevice 15 is to be operated for production of outside glue laps, frame 18 is operated to its raised position by rotation of lead screw 19. In this raised position, glue wheel 50 is positioned to apply glue to the upper surface of glue lap 600 (See FIG. 10 and 11).
  • lead screw I9 When glue unit 15 is to be used for applying glue to the lower surface of glue lap 60a, lead screw I9 is rotated to move frame 18 to its lower position in which the feed path for blank 60 is above glue wheel 50 as in FIG. 12. It is noted that with blank 60 moving to the right with respect to FIG. II and 12, glue wheel 50 must'appear to rotate in a counterclockwise direction to produce outside glue laps as in FIG. 10 and l l, and must appear to rotate in the opposite direction, as 'in FIG. 12, to produce outside glue laps. This apparent reversal of rotation for glue wheel 50 is achieved, without reversing direction or rotation for motor 48, by merely pivoting frame 35 with respect to frame element 18 about the vertical axis defined by pins 37, 38.
  • this vertical axis extends through the rota tional axis 46 of glue wheel 50 and also extends through a vertical plane positioned midway between the outer surfaces of glue wheel 50.
  • gluing unit 15 has been illustrated and described as including a pair of depressor guides 60, 70, as a practical matter, only a single depressor guide or single one of the depressor wheels 58, 63 may be furnished as part of the gluing unit. Under such circumstances each time the type of lap (inside or outside) being produced is changed, the position of the depressor guide or depressor wheel alone, as the case may be, is repositioned appropriately either above or below glue wheel 50.
  • the instant invention provides an insideoutside gluing unit with a single glue wheel, a single doctor blade, and a single system to apply glue to theglue wheel.
  • the gluing unit includes knife edge type depressors for directing sheet material against the glue wheel.
  • a gluing unit for inside and outside glue laps said unit including a frame; a single glue wheel rotatable mounted on said frame; a single glue doctor means mounted to'said frame and operatively positioned with respect to the periphery of said glue wheel to regulate glue film thickness thereon; first mounting means for operatively positioning a pressure means above said glue wheel for maintaining sheet material being moved above said glue wheel in glue transferring engagement with a first peripheral portion of said glue wheel; second mounting means for operatively positioning a means below said glue wheel for maintaining sheet material being moved below said glue wheel in glue transferring engagement with a second peripheral portion of said glue wheel; means for applying glue to the periphery of said glue roll at a location such that only doctored portions of said periphery pass opposite pressure means operatively positioned by said first and said second mounting means; a relatively fixed support to which said frame is movably mounted for operation between a raised and alowered position; with said frame in said lowered position pressure means operatively positioned by said first mounting means being on
  • a gluing unit as set forth in claim I in which said doctor means includes a doctor blade metering means.
