Description

"Method of Making a Book."

The invention relates to the production of books such as magazines, brochures, etc. and in particular a collation process in which books with Inserts or insert cards are collected.

The insertion of inserts in a magazine is known, there are a variety of collating systems which are designed so that an insert card can be inserted into the magazine. Either the deposits are inside attached to the magazine or they are available as loose cards etc. inserted in the magazine. In certain cases glue has been applied to the insert card to keep it within the To fasten the magazine or the magazine in a certain position. Reference is made to U.S. Patents 3,371,924, 3 658 31B and 3 663 007 pointed out.

In the production of books, which consist of several signatures and consist of a loose deposit, some difficulty arises j the problem consists essentially in that the loose insert move freely with respect to the signatures can and shifts during the handling of the stack of signatures during the completion of the book. When straightening out or shaking and when binding the stack of signatures, the loose insert can be shaken down and actually together bound with the magazine or book. Movement of the insert can also cause this during trimmed during cutting and thereby destroyed. In the U.S. Patent 3,663,007 shows what efforts are made were to avoid this problem) an arrangement is used, which the insert during each

809811/0860

Moves operations in new position to prevent trimming and destruction of the insert can.

Based on this, a method for the production of a book was created, which consists of several signatures or printed sheets and from at least one loose insert consists. This method avoids the problems of a loose insert in the manufacture of the books. According to the invention, the insert card is used during the collation of the insert and the signatures attached by means of adhesive to at least one of the signatures, in such a way that the insert during all, after the collection of the following work remains attached to the signature. As a result, the problems are eliminated which result from a displacement or relative movement of loose deposits.

A so-called volatile or Crystallizing adhesive used, which its adhesive property during a given Maintains time. After this period of time, the adhesive loses its adhesive properties, so that the Insert within the book or within the magazine becomes loose. The procedure is carried out so that all Work takes place before the point in time at which the adhesive begins to increase its adhesive properties lose. According to the invention, the insert is during The manufacture of the book is attached within the pile of signatures, but becomes loose after the Book was completed. The finished book resp. the magazine etc. consequently has a multitude of signatures within which a loose insert is inserted. During the production of the book, the insert is meanwhile attached within the collapsed stack. In this way, according to the present invention, the problems become apparent

809811/08 60

avoided, which can arise from loose deposits.

The invention is described below on the basis of exemplary embodiments with reference to the accompanying drawings explained.

Fig. 1 is a schematic representation of the process steps in the manufacture of a book;

Fig. 2 is a schematic representation of a collation system, which can be used according to the invention

Fig. 3 is a schematic illustration of another Gathering system which can be used according to the invention

As mentioned above, the invention relates to the production of books in the form of magazines, Magazines, brochures, etc., which consist of several signatures and at least one loose insert, see above a subscription card that is inserted between two signatures of a book. The method according to the invention can be carried out with various collating devices and systems are, which is why the figures of the drawing only show exemplary embodiments of systems with which the Method according to the invention can be carried out.

According to FIG. 1, books are manufactured according to the invention in a system which has a collation device 1, a cutting device 2 and a binding device 3. In the gathering device 1 are several signatures are collected and then entered into the binding device 3. The signatures are by means of a suitable sheet straightener mechanism

109811/0860

(not shown) jogged and straightened before they are fed into the binding device 3. After this Binding the signatures is the signature location of the cutter 2 and trimmed in this to complete the production of the book.

In the gathering device 1, the signatures gathered, according to the invention an insert between at least two of the signatures are inserted. According to the Invention is the insert by means of a so-called volatile or crystallizing adhesive on at least one Signature attached. A volatile or crystallizing one Adhesive has adhesive property during a certain period Time intervals, i.e. it loses these adhesive properties after the time interval has expired.

According to the invention, the deposit with the help of the volatile Adhesive is attached to a singature and remains during the entire production of the book, including during the all operations that are carried out after the book has been compiled adhere to the signature. the The insert or card cannot move relative to the signatures during these manipulations or actuations, the aforementioned problems do not therefore exist in the method according to the present invention. Though any adhesive which can be used as volatile or crystallizing applies, an adhesive is preferably used, which as L-6533 of the H.B. Fuller Company of Edison, U.S.A.

In Fig. 2 a collating device is shown which can be used in the method according to the invention. The collating device has four signature input stations. The stations are labeled 10, 11, 12 and 13. A collation conveyor 14 moves along the various Signature entry stations. The mechanical structure is the same at each of the input stations, which is why

809811/0860

Speaking parts have the same reference numbers.

The signatures or printed sheets are made at each station stored in a magazine or container 2G, the each bottom signature is brought into a position by means of a pull-off or absorbent body 21 in which the Edge of the signature is gripped by a gripper 22 on a rotating drum 23. The drum turns Timed in a known manner with the movement of the signature conveyor 14. The gripper 22 carries the signature around the drum and leaves the signature in a chain gap between sliding pins 24 of the signature conveyor 14 fall.

The signature that is released at station 10, falls into a chain or conveyor gap and becomes moved along station 11, such that a second signature on top of the released at station 10 Signature falls. The station 12 is intended as an input station for cards or deposits, i.e. that at the station an insert or the like falls on the signature which has been released at station 11.

When the insert is moved around the drum by the gripper 22, a photocell 30 senses the leading edge of the Insert from and triggers a spray gun 31, which is used for spraying adhesive, in such a way that this releases the adhesive sprayed or splattered onto the insert. The gun 31 used for spraying adhesive is from conventional structure, which is why a detailed description can be dispensed with. The spray gun 31 injects the adhesive at a predetermined position on the insert or card. The glue is as before mentioned, volatile or crystallizing, so that it is the Retains adhesive property for a certain time interval and subsequently loses it.

809811/0880

A photocell 32 fills the trailing edge of the signature and switches off the function of the adhesive 1 spray gun. By Appropriate positioning of the photocells is the position on the Insert can be determined where the adhesive is to be applied. The insert with the adhesive on it is held by the gripper 22 worn down and is released so that the insert rests on the top of the signature which is attached to the Station 11 was released. There is also a photocell sensor 33 is provided, which indicates that there is a signature in the chain conveyor and is used to receive the insert. If this signature is not available, the deposit is promoted, however, no adhesive is applied. The feeler 33 is of conventional type and controls the wear on the adhesive serving spray gun, in such a way that the adhesive is only applied to inserts if each has a signature is present on which the insert is to be attached.

The arrangement of the two signatures from stations 10 and 11 including the insert is carried along a roll 40 moved, which exerts a pressure on this arrangement and ensures that the insert within the Anoranung on the signature is attached. At station 13 another signature released on the stack of signatures in such a way that the collated Stack is completed.

This stack, consisting of the signatures and the insert, will then continue to be edited to produce a full book. Further processing includes straightening or jogging, binding and cutting. The deposit will During all of this further work with the help of the volatile adhesive kept on the signature until the book is complete is done. After the book is finished, the adhesive loses its property such that the deposit is within

80981 1/0860

of the finished book becomes loose. While handling the Signature stack in the cutting and binding stations however, the insert is held in a secure position with respect to at least one of the signatures and does not move relatively to this as mentioned above.

Another embodiment according to the invention is shown in FIG. 3 reproduced. In this embodiment, there are two deposits attached to a signature using a volatile adhesive The signature consists of two identical printed pages; in the Cutting machine, the signatures are cut in half to produce two books.

According to Fig. 3, signatures from the signature input states 51 and 52 released onto a signature conveyor 50. The from the input station 53 released signature arrives at a Conveyor - Intermediate Section 54. This signature is moving with the aid of a chain conveyor 55 having sliding pins along the intermediate section. The chain conveyor 55 moves the signature along a pair of insert input stations and 61. At each of these stations, a deposit is placed on the Signature abandoned, i.e. two inserts are attached to the signature, one from station 60 and one from the station 61. The same adhesive as in the case of the embodiment according to Fig. 2 is used, namely a volatile or crystallizing one Adhesive that is applied to the inlays before they touch the signature. The following is the signature with the inserts on them with the signatures of the containers or stations 51 and 52 combined.

Also remain in the arrangement shown schematically in FIG. 3 the inserts or insert cards during further handling of the signature stack attached to the signature, so during the trimming and during the rest of the binding work,

109811/0860

since these work processes take place during the time interval, during which the volatile or crystallizing adhesive still has its adhesive properties. After completing the book is the volatile or crystallizing adhesive loses its adhesive property, which become inserts so loose.

By using the volatile or crystallizing adhesive When making a book, not only are those Achieving the aforementioned advantages, another advantage is that the volatile adhesive is not in the mouth the glue spray gun dries out so that considerable Problems occur when the collator is turned off. So it's not a cleaning of the glue gun required, as is the case with other adhesives. .
