Wood Newspaper I 23 Claims,

This invention relates to improvements in rotary stuffing machines, that is, a machine wherein one section of a newspaper or the like is inserted into another section and the two sections then inserted into a third section and so on, according to the number of units or sections which may complete the entire issue of the newspaper;

The modern trend, particularly in Sunday newspapers, calls for a number of difierent sections, the main or primary news section'and other sections, some printed in black, others in color, including rotogravure sections, book sections and other special sections.

The practice generally followed is to print the various sections ahead of the date of issue which they bear, and in fact many of these sections are printed a. week or more in advance, some of them during the preceding week and the latest current news or main section on Saturday night or early Sunday morning.

To assemble all of these difierent sections intov one is quite an arduous and time-consuming task.

At the present time the usual practice is to stuff or insert one section into the other and so on by hand or manually.

In some of the larger newspaper oflices machines are employed which do this work of stufling or inserting the sections into each other automatically. In general, however, this is not satisfactory and is a very slow operation due in part to the large'number of reciprocating parts and complicated mechanism required.

The object and purpose of the present invention is to so construct a rotary stufiing machine,

such sections and after all sections have been inserted then to a closing device and then conveyed away from the machine.

It is quite important that the lower section being removed from the hopper or unit containing, such sections be removed therefrom in or by a rotary movement, that is peeled there-- from, particularly in view of the fact that the papers, due in some instances to the printing of the products on rotogravure presses will not permit of a sliding movement. of one section section, so that subsequent sections may be inserted therein.

A further object'is to provide a cam shaped guide or closing device for closing the section after the assembly has been completed, that is, after all sections have been properly inserted in the preceding section or sections.

v Referring to the drawings 'wherein similar numerals of reference are used to indicate corresponding parts in each of the several views:

Fig. 10 is a sectional view through the opener on the line l0--l0 of Fig. 1;

Fig. 11 is a sectional view through the opener 'on the line ll-ll of Fig. 1;

Fig. 12 is a sectional view through the opener on line l2-l2 of Fig. 1; Fig. 13 is a sectional view through the opener on the line l3l3 in Fig. 1;

Fig. 14 is a sectional view through. the closing device on line "-44 of Fig. 2;

Fig. 15 is a section through the, closing device on line l5l5 of Fig. 2; and Y Fig. 16 is a section through the closing device on line Ill-46 of Fig. 2.

The current news sections are stacked in the hopper l and the sections to be inserted therein stacked in the hoppers 2 and 3. Vacuum or suction cylinders 4 and 5 are provided, the suction being through the openings 6 and 1 leading into the openings 8 and 9 respectively which are connected to a suction apparatus. The bottom section IU of the stack of sections is rolled off of the sections above it by means of vacuum cylinder 4. This section it will be readily seen is rolled off the bottom of the pile without any sliding motion between the sections. The vacuum cylinders 4 and rotate in an opposite direction to the periphery of the main cylinder l I and at the same surface speed. Belts l2 and I3 support the stack of sections while the vacuum cylinder 4 carries the lower section and delivers it to the conveyor l4 and the vacuum cylinder 5 arrives in position to remove the next lower section from the stack.

The belts l2 and I3 also run in a direction opposite to that of the periphery of the cylinder II and at an equal speed. There is therefore no relative movement between these belts l2 and I3 and the stack of paper sections.

The belts l2 and I3 are driven by pulleys l5 and I6, which pulleys are in turn driven by the vacuum cylinders through gears l1 and I8. The vacuum cylinders are driven through fixed integral gear rings l9 and 20.

These belts l2 and I3 it will be seen, pass beneath and support opposite sides of the lower section in the hopper and thereby support the stack during the intervals of time between vacuum cylinder operation, that is, between the time when one section has' been removed by cylinder 4 and the cylinder 5 reaches its operative position beneath the stack for removing the then lowermost section.

The cylinder H rotating with the shaft 2| and the lower section 10 of the stack having been rotatively removed from the bottom of the stack is held fast on the vacuum cylinder 4 until said cylinder 4 reaches a position at the bottom of the cylinder in a position corresponding to that 00- cupied by vacuum cylinder 5, as shown in Fig. 3, whereupon the vacuum holding the section In to the vacuum cylinder 4 is released and the section II) deposited on the conveyor l4. This conveyor is constantly running in a direction in line with the axis of the cylinder l I.

The section 10 is then carried by theconveyor l4 in a fiat condition beneath a vacuum or suction wheel 22, which vacuum wheel by suction lifts or opens up the section H! at the corner 23 opposite the fold on the leading edge of the section, the section l0 constantly moving forward or along with the conveyor. This section with its corner 23 lifted then encounters a plow shaped former or guide 24 by which the section I0 is further opened and is carried in this opened condition beneath the next unit H which feeds the first section to be inserted to the conveyor in a manner similar to that previously described as to the removal of the sections from hopper l. Instead, however, of the bottom section of the sections contained in-hopper 2 being fed to the conveyor said section is dropped between the opened portion of section 10 and the remainder of said section. Section ID at this time has reached a position below the cylinder removing sections from hopper 2.

If further sections from other units are to be inserted the section ID with the section from hopper 2 inserted therein is carried forward by the conveyor beneath another vacuum or suction wheel 22, which, as previously, lifts a portion of the outer section NJ and the section' with the insert is carried to another opener or guide 24 and held in open position until a section from the next unit is in a similar manner delivered between the open portions of the section.

When there are no further sections to' be inserted the section I0 with its insert or inserts is then carried forward by the conveyor to a closing former or guide 25 through means of which the lifted portion of section I0 is closed or folded down upon the inserted sections.

A vacuum or suction wheel 22 of a similar construction is utilized in connection with each unit as in the first unit and a similar guide or opener is used following each unit. But one closing former or guide is used after the last unit.

The mechanism shown in section in Fig. 3 for rotatively removing the lower section from the stack of sections in its respective hopper is identical in each of the several units and operates in the same manner. v

The closing former or guide 25 is so shaped that the lifted portion of section l0 contacts with the side of the closing form-er 25, in the open condition of the section, as shown for example, in Figs. 14, 15 and 16. The continued movement of the section ID with its inserted section Illa along the closing former 25 gradually causes the lifted portion of section It] to be folded down upon the inserted section 10a. The completed assembly of the several sections is then conveyed away from the machine for delivery.

As stated above, the several vacuum or suction cylinders 22 are substantially identical in structure and operation,,and as many as need bemay be provided.

After the various sections, or as many as are desired to be inserted in the outside section have been acted upon, the outer section or open portion of the first section is closed by a former 25, which is located in a substantially reverse position to that in which the opening former 24 is located.

The inserted sections, of course, are not opened or acted upon by the formers but only the main or current news section which is taken from the hopper I.

After all of the sections have been inserted and the open portion of section In closed, the assembly of the various sections is delivered on toabelt or conveyor 26 for delivery to any de sired station.

The belts l2 and I3 are endless belts which travel over a series of rollers 21 and 28, the rollers being joumaled in a series of openings 29 and 30 of the housing or casing shown in Fig. 9.
