Mixed book signatures are fed into a machine which transports them one after the other past a camera where an image of each is captured. Each captured image is directed to an electronic computer which has stored within its memory images of limited areas of interest from selected signatures, as well as the location of each limited area within the overall signatures. As to each captured image, the computer compares the stored image with it, attempting to match each stored image with that location in the captured image corresponding to the location for the stored image. If the captured image identifies with a stored image, a controller activates a reject device along the conveyor, and that device diverts the identified signature from the conveyor. A separate reject device exists for each stored image, so like signatures are diverted and isolated at the same locations along the conveyor.

An electronic computer orders magazines of multiple titles from dispensing units, each of which has a single title assigned to it, and these orders are organized by carrier route, that is to say all magazines for subscribers of a specific carrier route are ordered in sequence. The orders are directed to a magazine dispensing unit which has a different pocket for each title, and these pockets deliver to the conveyor one after the other magazines that fill the subscriptions to which the various addresses pertain. The computer also causes the insert dispensing unit to deposit on the magazines as those magazines pass under the unit inserts that are appropriate to the magazine and its subscriber. Next a wrapping machine places a transparent polymer film around the magazine and any insert which is on it. Then the conveyor carries the magazine past an ink jet printing unit where the subscriber's name and address are applied to the polymer envelope, the printing unit likewise being connected to the computer. The conveyor thereafter deposits the magazines one after another in a stacking machine, which is also under the control of the computer, and it arranges the magazines in stacks which comply with the requirements for carrier route sortation, in that each stack has magazines addressed to a single carrier route, contains the minimum number of magazines, and does not exceed the prescribed weight.

A highly compact machine for applying an attractive protective coating to a paper web that passes through a printing press is located between the last press stand and the dryer of the printing press, and to enable the machine to receive the web, the printing press is provided with an apparatus for directing the web back to the print stands and the machine after the web passes through the dryer. The machine includes upper and lower blanket cylinders, a plate cylinder contacting the lower blanket cylinder, and an oscillating cylinder below the plate cylinder. In addition the coating machine includes a pan containing a coating fluid and a pan roller, the surface of which rotates through the fluid in the pan to lift it out of the pan. A metering roller revolves close to the pan roller to remove excess fluid from the pan roller which thereupon transfers the fluid to a form roller. That form roller runs against the oscillating cylinder and transfers the fluid to the oscillating cylinder. Another form roller contacts both the oscillating cylinder and the plate cylinder, and transfers the fluid to the plate cylinder. The plate cylinder delivers the fluid to the lower blanket cylinder which in turn applies it to the web. The plate cylinder carries a cylindrical plate which is normally continuous, but may be left with a cutout or void so that a small portion of the web is left uncoated with each revolution of the blanket cylinder.

A machine for stacking and bundling flexible sheets, such as the signatures that are delivered from a printed press, includes a succession of aligned conveyors. The sheets are deposited on the first conveyor where they accumulate in a generally horizontal disposition, one on top of the other, and the first conveyor withdraws sheets from the bottom of this pile and conveys them to a gate in a shingled condition. At the gate, which is narrower in width than the sheets, the sheets bow forwardly and rise upwardly at their leading edges until they stand on edge. It is in this condition that the sheets pass onto a second conveyor which moves them through another gate that is narrower than the first gate, so that the degree of bowing increases. The second conveyor moves slower than the first conveyor and as a result the flexible sheets consolidate in the upright condition on the second conveyor. Upon emerging from the second gate, the sheets pass between side conveyors which are closer together than the width of the sheets, and these conveyors also extend along a third conveyor. After a predetermined number of sheets have passed onto the third conveyor, that conveyor speeds up momentarily to produce a gap in the sheets, thereby separating the sheets ahead of the gap into a bundle which is forced onto a final conveyor. Boards are placed at the ends of the bundle, and the bundle is compressed and bound while in the compressed condition.

A card inserter for inserting post cards in a series of bound volumes in motion in a production line which includes a pair of horizontally reciprocated feed plates and associated hoppers arranged on opposite sides of a substantially vertical feed plane. A conveyor is provided in the form of a pair of flat endless belts positioned face to face, the belts being trained about a pair of driven pulleys at the inlet end to define a nip at the feed plane as well as pulleys for maintaining the belts in face to face relation along an angular conveyance path. A V-shaped diverter extends downwardly into the nip. The feed plates are reciprocated inwardly and outwardly in synchronism and have one-way frictional driving connection for simultaneous feeding of the lowermost cards against the diverter and thence into the nip so that the cards are delivered to the volume in register with one another. In the preferred form of the invention the feed plates are provided with vacuum ports to which vacuum is applied during the inward motion, and the feed plates are arcuately surfaced to facilitate separation of the lowermost card, with each feed plate having, in addition, a recessed one-way friction roller. Idler rollers on the inlet pulleys provide auxiliary driving nips enabling a shortened stroke of reciprocation. In one embodiment of the invention provision is made for feeding a third card along the feed plane for sandwiching between the first two cards.

A sheeter for feeding sheets in shingled relation to a point of collection including a source of sheets, a first conveyor belt and a second conveyor belt operating at substantially reduced speed so that the sheets are collected thereon in shingled relation. For snubbing the successive sheets so that they are decelerated and uniformly spaced on the second conveyor belt, a snubber is provided in the form of a knock-down roller arm rotating in a vertical plane at the upstream end of the second conveyor belt and so spaced therefrom as to press a sheet into engagement with the second conveyor belt, the arm being driven at a rotary speed which is synchronized with the source, with means being provided for adjusting the phase of the arm with respect to the source so that the arm engages the tail of each successive sheet. In the preferred form of the invention the conveyor belts are separated to form a gap occupied by a diverter, and a high speed nip is provided at the downstream end of the gap so that a sheet traverses the gap and is fed into the nip without changing its speed. For squaring up each sheet passing through the high-speed nip, a pair of squaring and press down rollers are provided at the downstream end of the second conveyor belt with means for adjusting the longitudinal position of the rollers so that they are engaged by the leading edge of the sheet just prior to engagement of the tail of the sheet by the knock-down arm thus insuring precise shingling and freedom from buckling of individual sheets. Infinetely variable cutoff is provided.

A machine for collating signatures has a pair of side-by-side gathering chains as well as feeding apparatus along the chains, with each feeding apparatus being adapted to open signatures and deposit them on the chain along that apparatus, so that the signatures accumulate on the chain in a saddle format. The compiled signatures are trimmed as they pass along the chain, and at the end of the chain they are discharged into a layup unit where they are turned from a vertical disposition to a horizontal disposition. The layup unit has at the end of each gathering chain a pair of high friction belts which come together at a nip into which the chains project the compiled signatures. The belts grip the compiled signatures near the folds in those signatures and move the depending portions of the signatures against and over a bar which deflects the depending portions laterally and into a horizontal disposition. The two sets of belts in the layup unit discharge the signatures onto a shingling conveyor in two rows, and on the shingling conveyor they overlap in a shingled condition. The shingling conveyor directs the shingled signatures into two stacking machines which arrange them in stacks that are conveniently removed and otherwise handled. The collating machine is very compact and requires a minimum of personnel to operate. Indeed, a single attendant may load the feeding apparatus for both gathering chains.

The printed ribbons in a high speed printing press are, while the press is operating at walk speed, directed onto a diverting conveyor prior to the forming board of the folder for the press, so that they do not pass through subsequent equipment which does not adequately handle the ribbons at walk speed. The diverting conveyor transports the ribbons away from the press and discharges them into a trash container, or at least allows them to accumulate where they will not interfere with the operation of the press or with pressmen working in the vicinity of the folder. By reason of the diverting conveyor, no pressman is needed to roll up the ribbons when the press operates at walk speed.

An assembling and addressing machine for magazines which are differently assembled in a number of different versions for sending to individuals falling into different demographic categories based upon interest, occupation or the like. A plurality of signatures are produced which are capable, upon selection in predetermined combinations, of accommodating all of the different versions. A gathering device gathers the selected signatures to form a book. Books in various versions are stored in temporary storage stations. The device operates under the control of address labels which include the address and indication of the demographic category. Means are provided for reading the category and for triggering release of a book from the corresponding storage station and to which the label is then applied. It is one of the features of the invention that means are provided in each storage station for sensing depletion and for signaling the gathering device to produce a group of books to replenish the depleted station. The temporary storage stations are in the form of conveyor belts arranged side by side and having hoppers at the output with individual dispensing means. Delay devices, preferably including memory, are interposed between a point where a given book is acted upon and a point of upstream release so that books may flow in unbroken series. Means are provided for calipering each book immediately following gathering of signatures with means for readjusting the caliper depending upon the version of book being measured. Automatic means are provided for insertion of cards into the book at the order of the address label.

Trimming apparatus for books and similar materials are detailed. Dynamic variability of the apparatus allows sizes of successive materials to differ in two dimensions—both from spine to face and from head to foot. The result is a processing system with substantially greater utility than presently available, as the system may process respective materials of multiple different sizes without stopping the apparatus to adjust positions of the cutting implements.
