BACKGROUND OF THE INVENTION four inserts may accompany the daily and-Sunday editions. The recent increase in Post'Office bulk mailing rates has contributedto the popularity of advertising in newspapers by inserts.

In the near future, printed newspapers will be delivered at belt speeds-of 70,000 newspapers per hour.

. Thus, devices for separation and the stuffing of the newspaper are required to'be accomplished at this speed in order to stay abreast of innovations in the newspaper printing industry. Conventionally, separating is done on a rotary rack, the sides of the paper being split by'a reciprocating pawl, or by vacuuming, and the stuffing is induced vertically from above.

1 Curry uses a shaped guide, as well as lateral vacuum discloses apparatus constituting an improvement and innovations over such known prior art and constitutes a substantial advance to the newspaper industry. The present invention relates to improvements and additions over and above our prior apparatus.

SUMMARY OF THE INVENTION According to the present invention, the folded newspaper is fed into separating and supplement inserting zones bymeans of feed-in rolls coacting with a deflecting baffle. The so fed newspaper is rotatably grabbed on opposite sides adjacent the bottom by a plurality of rollers, and moved into sliding contact with a plate strip, such as teflon, that'allows the paper toslide along until it is contacted with an opener in the nature of an upwardly tilted pointed probe, in proximity to the upper open side ofthe. newspaper, which serves to initially open the bundle constituting the newspaper.

Subsequently,, the so opened newspaper is conveyed by means of a mo ving conveyor belt coating with a holddown mechanism which also aids as a positive drive mechanism to the opened paper. A guideway is provided to support the newspaper in its open position, or rotating wire bands synchronized withthe holddown mechanism may be substituted to carry the paper and prevent ink smearing.

Additional'objects and advantages of the invention will be apparent from the following detailed description of embodiments thereof, when taken together with the accompanying drawings in which:

DESCRIPTION OF THE PREFERRED EMBODIMENTS In our copending application above-identified, the method of separating a newspaper is schematically illustrated. Referring to FIG'. I the apparatus includes in operating sequence for continuous operation, a feed-in zone; a probe and opening zone; an opened paper conveyor zone; a supplement insert zone; and an opened paper and supplement registration zone. These zones are appropriately indicated on FIG. 1. As shown' in FIGS. 1 and 2 a folded newspaper 10 is fed into the apparatus in the feed-in zone and as is usual the feed-in mechanism includes a plurality of endless members in the nature of resilient springs 12 in a longitudinally spread parallel array, which are appropriately driven and 'which convey the newspapers into the present apparatus. The folded newspaper with its folded edge leading are fed over upper and lower sets of feed rolls 14 and 16, with the rollers in the sets being angled in an upward direction which. permits the paper to enter a feeder plate 18 of appropriate curvilinear configuration'with proper, and necessary curvature. The feeder plate 18 feeds the folded newspaper into a trough generally designated 20.

.Trough 20 is in the nature of an elongated guide channel. Double stacked rollers 22 which are appropriately driven, and being of a design and construction for cation the rollers shown at 22 may be identically constructed, for example, to have a bevel of 10", 4, and on their sides, while being mounted upon shafts 26 which are appropriately driven. These rollers pull the newspaper downwardly in trough 20 while at the same time urging itforwardly and into sliding contact with a fixedteflon slider strip or plate 28. The double stacked rollers areutilized in order to obtain earlier contact with the paper fed in this section. As the paper is advanced into the probe and open zone similar rollers 30 move the paper in the trough along the slider strip 28. The leading edge of the newspaper is contacted by probe 32 which is pointed and..disposed at an upward angle as shown. The mounting for the probe, which is adjustable, is generally indicated at 34 which permits vertical and angular adjustment'thereof. The probe is spring pressed bymeans of spring 36. The probe also is angularly adjustable by means of a bolt or the like shown at 38. The probe preferably is' constructed of milon, or the like, with a pointed end and pivotably supported uon the shaft. The compression spring and'adjustment mechanism permits varying pressure in a lateraldirection upon the probe.

In a preferred embodiment the probe or separator device consists of a 7 inch length of teflon rod having a 30 angle at its tip to initially penetrate the closed newspaper and start to open it. The rod itself continues to open ,the paper and is kept at an angle of 24. The penetration angle is reasonably critical since too small an angle would tend totear the paper, and taper over too long a physical distance to open it quickly. 'Too large an angle will buckle the paper. The rod angle to the base is preferably 24. However, it is adjustable'and an angle between l-35 appears'satisfactory.

The so initially opened paper is then passed into the open paper conveyor zone where the bottom folded edge of the newspaper is contacted by a movable belt conveyor 40 of any desired construction, such as a flexible belt appropriately mounted ondriven rollers 42. The newspaper is conveyed by the belt 40 along and through a an elongated guideway 44 having upper-inclined sides 44A and lower vertical sides 448, the guideway being open at the bottom to permit the newspaper to contact conveyor 40, and as seen from FIG. 5 the sides of the opened paper are supported by the sides 44A. The paper is thus supported in its open position during passage through this conveyor zone and subsequent zones.

A paper holddown mechanism generally designated 46 is operatively associated with guideway 44 and conveyor 40. This holddown mechanism consists of a series of metal plates 48 attached to a metal belt drive 50. This construction permits flexing around corners as shown. Spaced along the belt are a plurality of laterally extending arms 52 which protrude from each side of selected plates. In a preferred embodiment the arms are spaced approximately 24 inches and have a length of approximately 3 inches. These arms help as a positive drive mechanism to the open paper. The holddown plates actually hold the open paper against-the moving belt at the base. I

Conveyor 40 and holddown mechanism 46 are driven in synchronization and carry the paper through guideway 44 from the open paper conveyor zone into the supplement insert zone where the supplements can be inserted by any known mechanism. Following insertion the open paper and supplement are carried through a registration zone which is facilitated by means of the arms which serve as pusher and registering lugs.

In FIG. 5 a guideway 44 is shown and constitutes a workable embodiment. As the paper slides in this guideway however some ink may be smeared. In order to alleviate this situation a modified embodiment is shown in FIG. 6.whi ch includes open upper end trough 54 for reception of the folded edge of the newspaper and positioned thereabove a plurality of rotating wire bands 56 running in synchronization with the holddown mechanism to carry the paper rather than just support I it. Such a construction will substantially eliminate ink smearing.

The paper with the supplement inserted is then removed from the apparatus as shown for further disposition.

While preferred embodiments have been shown and described, obviously minor changes in details of construction can be effected without. departing from the spirit and scope of the invention as defined in and limited solely by the appended claims.
