A roll s of a paper fi.'C,ff for; supply n the :web D which is J to form .the corrugated'member, is

rrugated web, 'made-up of -webs Band-D, is

' mounted;-on frame I. eBelt l -isfldriven-by rollers IT and I8 rotatablvmounted:oneframe I. F-rom the conveyor belts l3 and 14 the single faced corrugated web is deposited on a slow moving endless conveyor belt 19, driven by rollers and 2| mounted on frame I. The conveyor belt 19 serves as a storage medium where the single faced corrugated web is deposited, and a supply accumulated. From the belt 19 the single faced corrugated web is picked up by roller 22 journalled in frame I. From rollers 22 the composite web is advanced to rollers 23 and 24 journalled in frame I. From roller 24 the single faced corrugated web is drawn between roller 25 and glue roller 26 journalled in glue pot 21 secured to frame I. A glue roller 28 rotating in liquid adhesive in glue pot 21 serves to deposit adhesive on glue roller 26 which in turn deposits liquid adhesive to the crowns of the corrugations on the single faced corrugated web in preparation for adding thereto a second face web.

The second face web F is drawn from a supply roll E on shaft in frame I. From the supply roll E the web F is advanced over rollers 30, 3| and 32 to a printing press base cylinder 33 operatively mounted in printing press base 34 secured to frame I. The said cylinder 33 carries the web F against impression cylinder 35 where one color of printing ink is applied to the web, the web is next acted upon by impression cylinder 36 which in turn applies a second collar of printing ink to the web F. From the impression cylinder 36 the web F advances over rollers 31, 38 and 39 all journalled in frame I. Between rollers 38 and 39 the web F is formed to provide a loop, with a dance roll 46 positioned in the loop to keep the web taut and to take up any possible slack in the web. From roller 39 the printed web is drawn by roller 4| journalled in frame I, thence the web is advanced to contact the outside diameter of heated drum 42 journalled in frame I. The drum 42 serves to aid in drying the printing ink so that the printed areas will not be marred by contact with other elements in subsequent fabricating operations. Roller 43 journalled in frame 1 serves to draw the printed web F from the heated drum 42 and advance it into position to engage the crowns of the corrugations on web D adhesively treated by glue roller 26. The web D having previously been combined with face paper web B to form a single faced corrugated web, then as previously explained, the crowns of the corrugations on the free side of the corrugated web D are treated with adhesive in preparation for receiving the printed web F which is brought into engagement with the web D and firmly pressed together by conveyor belts 44 and 45 supported and driven by rollers 46, 41, 48, 49, and 5|, all journalled in frame 1. While the belts 44 and 45 are advancing and pressing the webs B, D and F together to form a printed, double faced corrugated web, the composite web is carried through a heating unit 52 secured to frame I, where the web is heated to further dry the printing ink, and also to dry the adhesive and drive off any excess moisture from the web. From the heating unit the web passes through cooling units 53 secured to frame I. The cooling units are to quickly bring the web back to normal temperature.

The double faced, printed and dried web of corrugated paper board is next advanced to a web trimming device-which acts to trim dinal edges of the-web, if necessary, to the desired size. The trimming operation is performed in the conventional manner by cooperating rotary tools .54 and 55 journalled in frame I From the the action of endless, pressure and 5 the longitu- .ders 59 and and 63 rotatably mounted in frame trimming device the web is advanced to be acted upon by creasing

cylinders

56 and 51 rotatably mounted in frame I, which serve to provide the longitudinal creases in the we The next operation consists in transversely creasing, cutting and severing the web to complete the production of individual container blanks.

The transverse web creasing, cutting and severing operation is effected by the rotation of cylin- 60. Secured to the outside diameter of cylinder 59 1s a web severing knife 58 which operates to cut from the advancing web with each revolution of the cylinder. Also secured to the outer diameter of cylinder 60 at three points, spaced radially apart from the web severing knife 58, are creasing and cutting knives 6|. The outer ends of knives 6| serving to out the web, and the mid-portions of the knives, serving to crease the web.

The creasing and cutting cylinders 59 and 60 are operatively mounted in adjustable carrier unit base 62 supported on horizontally rotatable rollers 63 positioned on bracket 64 on frame I. The cutting and creasing unit is adiustable horizontally by the action of screws 65 supported in adjusting brackets 64. Fastened to the outer end of each holding screw 65 is a crank handle 66. The screws 65 are operatively positioned in tapped holes in brackets 64. It will be obvious that by turning the crank handles 66, the carrier unit base 62 may be moved horizontally backward or forward as desired, to move the cutting and creasing cylinders 59 and 66 to the proper position in order that the advancing web may be creased, cut and severed in register with the printing on the web.

The adjustable feature of the carrier unit base is an important part of this invention, because tion to the printing devices any accumulated error able variations in materials and operating mechanisms. Therefore, when the machine here described is in operation the operator must watch the register of the cuts and creases with the printed matter on the web. If the cuts and creases creep out of register with the printing, the operator must move the carrier unit sufficiently to bring the cuts and creases into proper register. This can be done without stopping the operation of the machine.

After the completed blanks have been cut from the web, the blanks are delivered, by rollers 61 l, to the delivery bin 16 situated adjacent to the delivery end of the machine.

Referring to Figure 3, which illustrates a. section of the printed, double faced, corrugated web, the edges 11 represent the edges trimmed by rotary tools 54 and 55. The longitudinal dotted lines 12 represent the creased lines provided by creasing cylinders 55 and 51. The transverse dotted lines 13, and the transverse full lines 14, represent the creases and cuts respectively made by the action of knives 6| in cylinder 59. The full transverse lines 15 represent the cuts made by web severing knife 58 which operates to out each blank from the advancing web. The printed matter on the web is represented by the numeral 16.

In the use of this machine, with each size of container to be made, materials of the proper ders 59 and 6B are likewise suitably changed pre- 10 in its i n W th printing unit; and m a s chine.
