The adhesive is applied onto the backs of the blocks from the bottom by a press on device by means of an adhesive pad (17). The adhesive pad is impinged upon by the press on device in such a manner that the back of the book forms a set of sheets on one side and then on the other side by exerting pressure while adhesive is imultaneously applied on the back of the book forming the set of sheets (FIG. 1).
Description
FIELD OF THE INVENTION
This invention refers to a method for adhesively binding a set of sheets of books, book blocks, booklets and the like by fastening the book block and applying adhesive to the sheets of the back of the book block.
BACKGROUND OF THE INVENTION
When adhesively binding sheets of book blocks and the like for small series or individual books, the stack of sheets, such as a book block, is clamped and is manually painted with liquid adhesive at its back. This method is time consuming and the adhesive which is applied from the top flows into the spaces between adjacent sheets so that the edge areas of said sheets become smeared, and so that too much adhesive is wasted.
THE INVENTION
It is an object of this invention to rationalize manual labor of adhesively binding fanned sheets of book blocks, and to substitute it by machine in order to increase the production speed, to reduce the adhesive consumption, and to handle the binding not only at higher speed but also to obtain a by far more stable and durable long term bonding for the bound products. In addition, the adjustment of the width of the back of a book block or the pitch for solid covers which are to be rounded, is to be clearly determined.
The invention proposes a method according to which a book block with it's back downwards is inserted into a clamping device and is clamped as well taken up by a supporting device which by means of an operating device is movable horizontally and rectangularly in view of the plane of the block, the adhesive is applied from below onto the back of the block by means of an adhesive pad, the adhesive pad is arranged within a container which is operated by a press-on device in such a manner that the back of the book block is fanned towards the one and subsequent thereto towards the other side and that simultaneously adhesive material is applied onto the fanned back of the book block, and the press-on device is controlled so that the trough for the adhesive pad performs a tilting/sloping movement.
The product to be bonded by adhesively binding the fanned set of sheets of a book block, which throughout the specification will be called the “book block”, is clamped in the usual manner so that the individual sheets and the back of the block maintain their poosition relative to each other, which is necessary for the bonding procedure. The clamped book block is firmly fastened and from below a pad soaked with adhesive or an adhesive applying plate is pressed against the back of the block. Subsequent thereto the adhesive pad pressed against the back of the block is moved in a direction rectangular to the plane of the sheets of the block, and at the same time is lifted or tilted on one side so that the back of the block is moved from a horizontal into an inclined, skewed position. Simultaneously, the pad is moved in longitudinal direction. In this manner the individual sheets of the stack are fanned at their back area so that a defined section of small width is released for receiving adhesive material. This type of fulling and massaging effect between the back of the book and the adhesive pad allows that adhesive is applied to a larger, exactly restricted area of the individual sheets within the back area of the block in a controlled manner, and that the surface provided with adhesive is increased as well the effectivity of the adhesive binding is clearly improved.
This method of improved binding by adhesive is performed by machine; clamping and fastening of the book block as well moving the adhesive pad and fanning the back of the block is achieved by a lever system, either by means of machine operated or by manual drive, and can be part of a production line as means for obtaining an automatically operating process of book binding or of a production plant, namely automatically feeding and clamping the book block, hanging of the book block into the block gripping device, opening and closing said gripping device, longitudinal movement, lifting, tilting the adhesive pad, adjusted to the format and the thickness of the book block, and removing the book block subsequent to the binding process as well discharging the completed book block and feeding a new book block.
According to a further embodiment of the forementioned process for binding fanned sheets of the back of a block the invention proposes to handle the book block obtained by said binding process in such a manner that a slip-fold is applied onto the back of the block and onto the lateral sections joining the back. The slip-fold is made from a strip of paper, fabric or the like material with dry adhesive, and is applied under pressure onto the adhesive binder. The edges of the slip-fold are pressed against the lateral sections of the block and are connected with each other by a heating and sealing process. The slip-folds can be applied onto a fabric tape as a carrier individually or are fed automatically so that this method step can be introduced and integrated into an automatically operating book binding system. In case of a machined system the slip-folds can be supplied continuously, cut into the required shape and positioned onto a printing table, lifted and pressed against the finished book block.
Means for performing the above-described method is a manually operated or machine-driven device, which as a unit is integrated into a larger system in order to allow an automatic operation within a production line. The prepared, clamped book block is (manually or automatically) passed into a gripping device with the both-sided clamping bars resting thereon. The gripping device is connected with the frame of the machine and is adjustable to different thicknesses of blocks. Operating said adjustment means is achirvrd fot example by levers manually or motor driven. The back of the book block extending downwardly and freely from the gripping device is arranged above an adhesive applying device, which comprises a trough and an adhesive pad arranged therein. The trough is movable in height, movable in length and tiltable in view of the adhesive pad so that by corresponding driving means (manually or by motor) a horizontal movement, a vertical movement and a tilting movement in both directions canl be obtained. The course of movement is controlled by connecting link means the route of which can be transformed by controlling drums onto the trough and the adhesive pad arranged in said trough.
Connected with the trough is an adhesive source which supplies the adhesive pad with sufficient adhesive continously. The adhesive is a wet dispersion adhesive which is received by the felt pad within the trough so that the surface of the pad facing the underside or the back of the book block, is continuously available. The felt pad is sealed by a covering foil or a covering plate as long as the device is not operating so that the device is always ready for operation, and adhesive at the upper side of the pad is available if the covering foil or the covering plate is removed.
The forementioned device for adhesive binding of fanned sheets of a book block or the like is supplemented by a further device, by means of which a slip-fold in the form of a fabric strip, for eample from linen, together with adhesive, is mechanically applied onto the book block or the like mechanically. Such slip-fold can be formed as a continuous carton folder. The book block bonded by adhesively binding is inserted into a gripping device in a clamped condition. Below the gripping device a pressure plate is arranged, which is adjustable in height, and is covered by a textile or similar fabric web, which is silicone-coated at its upper side. Onto this web an adhesive strip made of fabric-type material is applied associated to the back of the block; the upper side of the adhesive strip facing the back of the block is provided with a dry adhesive layer. The adhesive strip is folded around the two edges of the back of the block so that it covers the lower section of the two opposite lateral walls of the book block.
These two lateral sections are in contact with a heater bar which heats the adhesive of the adhesive strip, and by a sintering-type process results in a firm bonding effect with the adhesive at the back of the block as well a firm bonding with the two opposite cover sides of the book block. The slip-fold forms a strong connection between the slip-fold and the book block as soon as the heating process has been completed. It is important that the wet dispersion adhesive for the adhesive binding of the back of the book and the dry dispersion adhesive of the slip-fold are matched in view of each other in order to obtain an optimum bonding and a sintering effect between both. The above described device for applying a slip-fold onto book blocks, brochures, continuous carton folders or other stacks of sheet material requires a supplemental device in addition to the device for adhesive binding so that both devices can be units within a book binding installation or a production line, and as well the adhesive binding as the slip-fold binding can be designed in such a manner that an automatic operation mode and an automatic supply of the binding elements and the matching of the operation stepscan be achieved.
Instead of performing the driving movement for the adhesive applying device by means of a mechanical connecting link control, said driving movement can be performed with a movable container carriage mechanically, pneumatically, hydraulically or electrically by means of correspondingly controlled driving cylinders fffor achieving a lifting movement.
Preferably, the adhesive container is moved on rollers and is driven up an inclined plane formed as a tilting lever or a rocker, which plane is tilted at the lifting end around a tilting axis so that the adhesive container moves downwardly along the tilting lever and back again into the starting position. Subsequent thereto, the tilting lever or rocker is automatically tilted back into the starting position by spring means and the adhesive container in the starting position is moved to the opposite side beyond the tilting lever and subsequent thereto upwards the inclined plane of the tilting lever at the opposite side so that the above described operation cycle is repeated. On said opposite side the adhesive pad can be driven into a parking position in which the trough by means of a cover is sealed automatically by a cover so that the adhesive material-during the parking time will not dry out. In this manner the adhesive within the adhesive pad cannot dry out, and the adhesive pad is ready for operation at any time.
This embodiment is designed for manually or mechanically controlled operation. For an automatic, for example pneumatic operation, basically the same carriage or container can be supported on a scissor's grid arrangement and moves on rollers guided in tracks so that the relative movement in view of the back of the book block can be performed, whwn adhesive is applied. For applying adhesive the adhesive pad is lifted under the book block and is pressed against the book block, whereby the back of the book block is taken along, bent over, fanned and adhesive is massaged in it. At the turning point of the fanning step the container together with the adhesive pad is lowered again and is driven back to the center. The same cycle of operations is performed at the opposite side. The lifting movement can be performed pneumatically or motor-driven, the forward movement is preferably motor-driven. Cylinders are hingedly connected with the container receiving the adhesive pad which cylinders perform a tilting movement of the adhesive pad when the container is lifted so that the adhesive pad rests flat against the book block being fanned, and so that adhesive is taken up in an optimum manner.
With this mode of driving movement the adhesive pad within the trough is pressed against the back of the book, as well upwardly as laterally. With such lateral movement the stack of paper is compressed at the position the guiding rollers revert their direction of motion. Taking up adhesive at this location of compression is restrained so that adhesive is no longer applied correctly. In order to avoid this disadvantage the movement of the adhesive trough can be provided with the rollers at both sides of a pivot lever, and during this pivot movement adhesive is transformed to and massaged into the back of the book.
With the method and the device according to the subject invention an adhesive bonding for books, book blocks, brochures, but also carton folders is obtained in an extremely simple and inexpensive manner, which results in a high degree of durability and stability of the products bound in this manner which is superior to conventional adhesive binding in view of stability, durability and costs.

In order to allow an exact production of solid book covers rounded at the back, when slip-folds are to be applied to the back of the book the pitch of the back of the book block can be calculated from the height a of the stack of sheets of the book block and the extra size at the back in the amount of 2×2b (b=thickness of the cardbord) as well an extra measure corresponding to the required roundness of the book betwen 0 and 15%. With a height of the paper stack of say 30 mm and an additional measure at the back of say 2×2=4 mm thickness of the cardbord the total measure will be 34 mm. If an additional measure of 15% corresponding to the roundness of the back of the book is considered which is about 5,1 mm, the width of the back will be 39,1 mm. With this value the required pitch can be adjusted.
