REEL WITH BRAKE FOR WEB SUPPLY TO PRINTING PRESS Filed Dec. l, 1961 INVENTOR.

HARRY JILBERT ATTORNEYS United States Patent O 3,127,125 REEL WITH BRAKE FOR WEB SUPPLY TO PRWTING PRESS Harry Jilbert, 118 E. %th St., Rochester, End. Filed Dec. 1, 1961, Ser. No. 156,325 1 Claim. (Cl. 242-754) The present invention relates to printing presses and more particularly to an attachment for prlnting presses for final printing and inserting preprinted pages in newspapers and the like.

Preprinted multi-color inserts, particularly for advertising, have become increasingly popular in the last few years and are being extensively used in metropolitan and other large newspapers. The preprinted colored inserts are often prepared in large rolls by or for an advertiser with only one side or portion printed and are shipped to the newspaper where the remaining side or portion is printed and the inserts folded into final newspapers as an integral and conventional part thereof. The large rotary presses used in the printing plants of the large daily and Sunday newspapers are constructed to handle the inserts so that with the advent of the partially preprinted colored inserts, commonly referred to as thi-fi inserts and rolls, no diiculty was encountered in meeting this advertising and printing demand. However, many small printiug establishments, particularly the small town and community daily and Weekly newspapers, use flat bed presses in which the paper is printed from a single strip of paper supplied to the press from a single roll and then slit into sheets of the final size and folded into the complete newspaper. In the past, no means was available for feeding, printing and inserting the partially preprinted sheets or inserts into the newspapers and the like on the flat bed presses; consequently, these publishers have been denied the business from advertisers insisting upon the preprinted inserts. One of the primary objects of the present invention is to provide an attachment or mechanism for presses which makes possible the insertion of preprinted pages in newspapers simultaneously with the printing, slitting and folding of the newspapers on flat bed presses and which can be incorporated in the conventional flat bed press without any substantial changes or modifications being required in the basic Construction of the press.

Another object of the invention is to provide a method of feeding, completing the printing, and inserting partially preprinted pages simultaneously with the feeding, printing and folding of the standard printed pages of the newspaper.

Still another object of the invention is to provide a mechanism or attachment for feeding preprinted strips of paper into a fiat bed press, which can be readily mounted on the press in Operating position When such inserts are to be included in t-he final printed paper and which can be easily removed from the press when the inserts are not required, permittng the press to be operated in the conventional manner.

A further object is to provide a flat bed printing press adapted to handle both the conventional printing sheet and a preprinted sheet simultaneously, from the feeding of the sheets from the original rolls through the printing, slitting and folding Operations to the completed newspaper or other similar printed matter.

Another object of the invention is to provide a relatively simple, easily fabricated and installed feed or reel for both kinds of the aforesaid paper sheets in a fiat bed press operation, which is readily adaptable to various sized rolls and widths of sheets on the rolls and which can be efiectively adjusted to maintain the proper tension on the rolls throughout the operation of the press.

Additional objects and advantages of the present inven- 3,l27,l25 Patented Mar. 31, 1964:

tion will become apparent from the following description and accompanying drawings, wherein:

The present reel mechanism is directed to a type particularly adaptable for flat bed presses in general use throughout the country, particularly for small daily newspapers where continuous rotary presses are unnecessarily large for the circulation or demand. The flat bed presses to which the present invention relates will not be described in detail herein since the Construction and operation thereof are well known and do not form a direct part of the present invention. Briefiy, flat bed presses consist of two beds, one above the other, and the paper strip or web is threaded over guide rollers passing first over one set of type forms to be printed on one side and then reversing to be printed on the other side. Rotating impression cylinders roll back and forth to press the paper against the type, and the paper strip is fed into the press at an even rate of speed and comes out of the press also at a continuous, even speed. However, while the paper is being printed, the web stops long enough for the stationary type forms to be impressed upon the paper. This is achieved by moving the rollers which rise and fall in rhythm in and paying out the slack in the paper strip by lengthening and shortening the detour around which the paper has to pass. The present reel coperates with this operation and feeds the two or more rolls of paper from the reel with a substantially constant and uniform tension between the several rolls of paper mounted thereon. For the purpose of the present description, the press thus far described and the rolls of paper used in conjunction therewith are considered as conventional and will not be described further here.

Referring more specifically to the drawings, numeral 10 indicates generally the present reel mechanism having mounted thereon a standard or conventional roll of newspaper 12 and a roll of partially preprinted multi-color paper 14, the paper of roll 12 being plain, i.e. unprinted on both sides, whereas the paper of roll 14 is printed on one side as it is mounted on the reel, usually being printed in multi-colors with a particular advertisement or special insert for the paper. The type of paper described here is frequently referred to in the trade as hi-fi paper and is now extensively used in the metropolitan newspapers where it can be readily inserted therein on the large rotary presses, but which in the past has not been readily usable in papers printed on flat bed presses, such as those referred to hereinabove.

Rolls

12 and 14 are mounted on and supported by a shaft 16 above pit 18 in the floor of the press room near one end of the press, the ends of shaft 16 being supported in plain or roller bearings 20 and 22, which are mounted on and Secured to the floor 23 of the press room at the edge of pit 18. Shaft 16 rotates freely in the two bearings and is controlled by a brake mechanism 24 Secured to the shaft at one end thereof and to a suitable control mechanism of well known Construction, not shown in detail herein. The brake mechanism 24 adjusts the tension placed on large roll 12, which rotates in unison with shaft 16.

The standard roll of ,paper 12 is supported on shaft 16 by

inserts

32 and 34, which are keyed or otherwise secured to shaft 16 by set screws, or any other suitable retaining means, and which extend into core 36 of the paper roll. The inserts are provided with a tapered portion 38 for slipping into the open ends of core 36, and with a plurality of splines or triangular tapered ridges 40 spaced evenly around the periphery of tapered portion 38 for gripping the ends of the core for rigidly holding the core, and consequently the paper roll, on shaft 16 for rotation therewith.

Inserts

32 and 34 are provided with a radially extending fiange 42 for seating against the end of core 36 and the adjacent end of roll 12. The bore 44 of

inserts

32 and 34 is only slightly larger than the diameter of shaft 16 so that a relatively snug fit is obtained between the shaft and the inserts.

Roll 14 is mounted on the shaft on insert 50 having an inwardly extending tapered portion 52 with splines or triangular ridges 54 thereon of the same shape and design as those shown on

inserts

32 and 34. The insert 50 is also provided with a radially extending flange 56 for seating against the end of core 58 when tapered portion 52 has been inserted in the end of the core. Insert 60 consists of a tapered portion 62 having on its external surface splines or triangular tapered ridges 64 equally spaced around the tapered portion for slipping into and gripping core 58 of roll 14. Attached to tapered portion 62 is a cylindrical portion 66 having two

radial flanges

68 and 70, fiange 68 seating against the end of core 58 and the paper thereon forming roll 14. Cylindrical portion 66 forms a brake drum for cooperation with brake mechanism 72 for controlling the tension on the paper of roll 14. Tapered portion 62, cylindrical portion 66 and

flanges

68 and 70 are integrally joined to one another, forming a rigid structure having a center bore 74 therethrough for slipping onto shaft 16.

Inserts

50 and 60 are adapted to rotate freely on shaft 16 so that

rolls

12 and 14 can rotate independently of one another.

The manner in which

rolls

12 and 14 are mounted on shaft 16 is illustrated in FIGURES 3 and 5, inserts 32 and 34 seating snugly in the respective ends of core 36, and inserts 50 and 60 seating snugly in core 58 of roll 14. The two rolls are placed end to end in close proximity, preferably no further apart than about three-sixteenths to one-quarter of an inch, the two

inserts

34 and 50 being separated by a lubricating or non-friction Washer 76 so that the two inserts can rotate relative to one another without undue friction therebetween. After the four inserts have been assembled in the two

rolls

12 and 14 as shown, the shaft 16 is slipped through the bores of the four inserts, and

non-friction washers

78 and 80 are placed against the outer ends of insert 32 and insert 60, respectively. The entire assembly is held in assembled relationship on shaft 16 by

end collars

32 and 84, each collar consisting of a split ring 'having a slot 86 and a plurality of bolts 88 extending through the two portions on opposite sides of slot 86 for tightening the collar firmly on shaft 16 after the parts of the reel have been assembled thereon.

The details of the braking mechanism 72 for controlling the tension on the paper being unreeled from roll 14 are best shown in FIGURES 4 and 8, the brake portion consisting of

shoes

90 and 92 pivoted to one another on pivot pin 94 and drawn together by an adjustment bolt 96 pivotally attached at one end to shoe 92 by pin 98 and pivotally attached to shoe 90 by pin 100. The screw is threaded throughout most of its length and is provided with a nut 102 disposed on the free end thereof and seating against tension spring 104 between the nut and pin 100. The adjustment screw passes through a hole 106 in pin and slides relative to the pin as nut 102 is tightened or loosened in making an adjustment on the brake. The brake portion 72 is assembled on brake drum 66 in the manner shown in FIGURE 4 with torque arm 108 being rigidly Secured to brake shoe 90 by a bracket 110 at one end and resting on the floor of pit 18 at the other end. The amount of tension on the paper being unreeled from roll 14 is varied by varying the setting of nut 102, which causes

shoes

90 and 92 to grip drum 66, the torque arm preventing rotation of the two shoes with the reel as the nut is tightened to increase the tension. Preferably,

friction material

112 and 114 is provided on the inner sides of

shoes

90 and 92, respectively, for engaging drum 66. A brake mechanism of somewhat similar Construction is contaned in mechanism 24 and is adjusted by adjustment screw 116 to vary the pressure of shoes 118 and 120 on shaft 16.

In the operation of the present dual reel, roll 12 of standard printing paper is mounted on

inserts

32 and 34, and a preprinted hi-fi" paper is mounted on

inserts

50 and 60 in the manner shown, and the strips from the reels pass beneath a roller 122. With the two

brake mechanisms

24 and 72 properly adjusted, the paper is unreeled from the two rolls and fed through the press in the conventional manner. The brake mechanisms are adjusted to provide the desired tension, and the amount of paper removed from each roll remains constant with respect to one another. It is apparent that the strips of paper removed from the two rolls, being closely spaced to one another, feed into the press substantially the same as a large single sheet and are printed as if only one sheet were being fed to the press. After the paper rolls 12 and 14 have been assembled in proper feeding position in the reel, as illustrated in FIGURE 3, the reel and press operate in the same manner as a conventional reel with the exception that one slitting operation on the paper is eliminated, the paper in eifect having been pre-slit.

The reel is constructed to handle both standard and pre-printed paper of different widths and may be used to hold more than two rolls, if required, and other types of inserts may be substituted for those described above, FIGURE 9 illustrating an insert used in conjunction with a returnable core consisting of a hub 124 with a flange 126 at one end and a key or lug 128 for interlocking with a slot in the end of the core While only one embodiment of the invention has been described in detail herein, various changes and modifications may be made to suit requrernents.
