Description

Method and device for the production of folding books o. The like. In Book stitching machines The invention relates to the production of such books, where short folds are stapled around or between the individual layers, such as this z. B. in album production, business books, etc. is often required. You should automatically insert these folds between the layers during stitching . possible, whereby it is irrelevant whether the introduction to the forming and inserting the folding loop initiated by an impulse from the stapler or automatically through the machine when a loop is placed behind each newly tacked layer should be made.

The formation of the folding loop can with the production of the known per se Loop of the backing material between every two books to attach the book cover connected, but can also be a mechanism on its own form, which allows the insertion of staples, which the protruding back material insert. The invention is based on the idea that is necessary for the formation of the folds Material lying flat, possibly coming from the roll, regardless of the Feeding of the backing material thereby after each stitching or in corresponding Insert sections of the staple so that it goes through behind the stapled layer a corresponding organ is bent a piece that may be adjustable under certain circumstances, so d.aß the next approaching layer or the scraper it loops pushes between the arches.

So far, this work has only been done by hand in such a way that the existence. Previously pre-folded paper strips according to the number of layers in a zigzag inserted in wire stitching machines and after each stitching that is carried out very carefully was folded by hand with the machine disengaged at the desired point, whereupon the new layer was placed on top of the other in a known manner and stapled. One different type of manufacture of those creased books was made possible on the single sewing machine, that each layer individually on the; Corresponding fold of the smooth again: ey drawn, pre-folded in a zigzag Streiei laid and in. Fold the location through, -, estep: was. The back material for the binding had to be subsequently attached to the layers in some way will. The current way of producing folded books is therefore a major step forward represents not only a performance that has been increased many times over, but also a corresponding one Improvement and cheaper work results.

in the drawing is the inventive idea in one embodiment , on, of a thread book stitching machine.

Fig. I shows as far as this is necessary for an understanding of the invention Fig. 2 is a side view of a booklet machine, Fig. 2 is a side view applied bow.

Fig. 3 is a similar view in which the between the layers The fold to be placed is pushed down, Fig. 4 the same view with through the Scraper fixed fold edge.

Fig. 5 shows an example in which backing and folding material are used at the same time between two. Books is pressed.

Fig. 6 shows the finished double fold, Fig. 7 an example in which is worked with sticks between each of the books. The paper layer i is on the Satte12 swinging back and forth (Fig.3) and in the direction of the arrow under the on the needle plate 3 seated needles 4, 5, brought. These penetrate the fold the position and carry out the stitching in a known manner, whereupon the saddle 2 goes back, the stapled layer is pushed back by a scraper 13 and a new one Situation comes up.

In order to be able to fasten the resulting stapled book in the cover, spine material in the form of gauze, tape 0 are obtained by inserting sticks (Fig. 7) or in the form of a loop (Fig. 5, .6). This backing material comes from a roll 6 (fig. I) and to the needle bar 7 around on the back of the stapled sheets case brings overall (Fig. 2). A second spool 8 (Fig. I) can contain the material used for pleating, endlessly or already cut to a suitable length. It is also over the back. of the attached layers. Immediately below the web of this strip, io organs ii are attached to holders swinging around 9, which move at the appropriate moment to the office, take the folding path a little:, and put in the form of a loop 12 in front of the last stapled layer (Fig. 3 ), where - ";Ui; the necessary material is re-drawn from the spool 8. In order to ensure that the folding strip is carried downwards, the front edge of the organ ii can, for example, be stolen or claw-like in order to prevent the organ from descending ii to attach to the fabric web, ab - r slide smoothly over it in the reverse movement. The operation of the scraper 13 is carried out in a known manner. The next upward swinging layer or the scraper 13 (Fig two layers to the last stapled layer and press back the entire book block to make room for the new layer.

Since the stripper 13 inevitably follows the cycle of the machine after each stapling is moved, this movement can be used to actuate the organs i i (Fig. 2). Both movements can, however, also take place independently of one another, as is the case the Z. B. in. Fig. I and 3 to 7 is provided, where by pressing down the holder OK, the formation of the folding loop can take place. Even the triggering by the foot the stapler is possible. After completing each book, the illustrated The stitching machine (Fig. 2) produces the empty stitch with the pawl 15 switched off. this Switching off is done by pressing the back of the drive pin 17, which is usually in the drive pin 17 lying pawl 15. This then also remains the release device i i for this Stab in peace.

When a new layer is stapled, the pawl 15 automatically snaps onto the bolt 17 and transmits its movement back to holder i o the next time separated together with the separation of the books by moving a knife along the groove 18. Similar can. also the separation of the individual books z. B. done with scissors, if instead of the sticks @ appropriate loops of the back material are inserted (Fig. 5 and 6). The holder io and the lever 1 6 may also be connected analogously to one another so that, when pushing down the lever 16 .the bottom edge x of the organ i i wherein Y is (Fig. 5) and thus two identical loops of the gauze and Fälzelmaterials yield.

The stroke of the organs i i can be made adjustable in any way in order to be able to regulate the width of the rebates as required. Instead of the paper material could also any other material, e.g. B. a cotton fabric, canvas jo. Like., can be used. The same can be done on a book stitching machine The device shown can also be used on wire book stitching machines.

Claims (3)

PATENT CLAIMS: i. Process for the production of folded books, albums, Business books or the like in book stitching machines, characterized in that this is advantageous Fälzelmaterial coming from a reel between two stapling processes after completion the first in front of the attached layer bent out in the form of a loop and from the following layer or the scraper to a fold lying between the two is determined. 2. Apparatus for practicing the method according to claim i, characterized characterized in that one or more claw-like claws are used to produce the folding material loop Folding elements (i i) are guided against the paper tape, which is thereby removed from the spool . is peeled off and shaped into a downward loop. 3. Device according to claim 2, characterized in that the folding element (i i) with the scraper (13) of the book stitching machine cooperates in such a way that the one formed by the folding element (i i) Loop through the scraper with the newly stapled layer is folded in place.
