Description

Field of the invention

The invention relates to the field of bookbinding and in particular to be used in books, folders and folders solid bindings and usable for their production devices.

State of the art

The applicant for the patent relates to the production and planning of finishing equipment in the graphic arts field.

We have developed devices that are used to make strong bindings. Such are, for example, solid bindings usable in books, folders and folders. We generally use the term hardcover maker for the devices and the term hardcover for hard covers.

With a hardcover device, lid reinforcements generally used in hard covers are placed in place on a lid sheet containing adhesive, and the lid reinforcements are adhered to the lid sheet.

The edge folding unit of a hardcover is a part of the hardcover device, a separate accessory part of the hardcover device, or a separate device for folding and gluing the part of the lid sheet extending beyond the edges of the lid reinforcements onto the lid reinforcements.

One of the edgebanding units we manufacture is in the international patent application WO 01/87638 (hereinafter '638 Application) described on 16.05.2001 claiming the priority of our patent application filed on 19.05.2000. In the edge folding unit, the part of the lid sheet going beyond the lid reinforcements is folded and adhered to the lid reinforcement using a spring-loaded roller and a stopper surface.

In a second edgebanding unit manufactured by us, disclosed in the international patent application WO 2007/085684 (hereinafter '684 application, filed January 19, 2007 claiming the priority of our patent application filed on Jan. 25, 2006), such an edge folding unit is used in which the part of the lid sheet extending beyond the lid reinforcements is folded and onto the lid reinforcement is glued using a roller encrusted at its ends and a stop surface. In the '684 application, the edge folding unit rests against the rear edge of the hardcover device.

In our product Fastbind Casematic H32 Pro, which is presented as Community Design under 001526443-0015, which was filed on 27.05.2009 (hereinafter H32 Pro), such a Kantenfalzeinheit is provided in which the over the lid reinforcements outgoing part of the lid sheet folded and adhered to the lid reinforcement using a roller encrusted at its ends and a stop surface.

Object of the invention

The use of an encrusted at their ends role increases the manufacturing cost of a Kantenfalzeinheit not insignificant. First, the rollers are heavy and their dimensionally accurate manufacturing expensive. Second, the parts required to hang the roll or rolls are expensive. Third, the equipment required to regulate the suspension of the roll or rolls is expensive and it is labor intensive to keep it calibrated to ensure high quality manufacturing.

According to a first aspect, the object of the invention is to simplify the construction of the edge folding unit and thus to reduce the manufacturing costs. This task can be solved by the edge folding unit according to protection claim 1.

According to a second aspect, the object of the invention is to simplify the construction of the hardcover device and thus to reduce the manufacturing costs. This task can be solved by the hardcover device according to protection claim 9.

The dependent claims describe advantageous embodiments of the edge folding unit and the hardcover unit.

Advantages of the invention

The edge folding unit for finishing hardcures usable in books, folders and folders comprises a first folding strip and a second folding strip attached to a base plate. The first folding strip and the second folding strip are both each provided with at least one addition. Between the first folding strip and the second folding strip remains a slot whose width is such that the part of the lid sheet extending beyond the lid reinforcement of the hardcovers to be finished goes out, foldable over the lid reinforcement and adherable thereto Insertion of the lid sheet and the partially bonded lid reinforcement or lid reinforcements between the first rabbet and the second rabbet. Such an edge folding unit can be realized much more easily mechanically than the prior art edge folding units, because at their ends, faceted, rotatable rollers, their suspension and regulation are not needed.

If the width of the slot between the first folding strip and the second folding strip of the Kantenfalzeinheit is adjustable, can be finished with the Kantenfalzeinheit Hardcover of different thickness. If the adjustability of the width of the slot is realized by an openable attachment disposed through the base plate from the underside of at least one of the first folding strip and the second folding strip, the attachment can be realized such that the attachment completes the finishing of the cover not bothered by it being an obstacle. This improves the user friendliness of the edge folder unit.

When the additive comprises at least one elastic component in an area between the folding strips, preferably such that a strip of synthetic rubber, in particular chloroprene rubber, polychloroprene or chlorobutadiene rubber, remains on the part remaining between each of the two of the first folding strip and the second folding strip , Is attached, a pressure can be generated by means of which adheres the unpaved part of the lid sheet on the lid reinforcements and on the back insert.

If the additive additionally comprises a woven fabric, preferably such that in the edge folding unit the first folding strip and / or the second folding strip has the shape of an inverted U-letter from the profile of its middle part, wherein on the inside of the one or both profile feet a hook-and-loop fastener tape By means of which the fabric fastened to the opposing hook-and-loop fastener tapes can be exchanged, the elastic component can be protected from damage and its surface can be kept reasonably smooth. If the fabric is interchangeable, the folding strip or the folding strips of the edge folding unit can be provided with a new cover. Compared with the H32 Pro device, where we have used a hard special coating in its seaming roll, eliminating the seaming roll in this way can greatly simplify the manufacture of the edge folding unit and reduce manufacturing costs. By attaching the fabric on the inside of the profile foot from one side, the space required in the depth direction of the edge folding unit can be slightly reduced. By attaching the fabric on the inside of the profile foot from both sides, the space required in the depth direction of the edge folding unit can be considerably reduced.

If approximately 30 × 30 mm have been selected as the profile of the folded strip produced from thin sheet metal by folding, the edge folding unit can be realized approximately 60-70 mm deep according to the embodiment described above, ie only a little deeper than the depth of two juxtaposed folding strips would. By attaching the fabric on the outside of both folding strips, the depth of the device would be at least 130 mm, taking into account that the width of each Velcro strip is at least 15 mm. It will be appreciated that a smaller depth facilitates the use of the hardcover device that may be used in conjunction with the edge folding unit, especially if the edge folding unit is on the front of the hardcover unit.

When the base plate is at least partially protected in a region between the first folding strip and the second folding strip by a piece of synthetic rubber, in particular chloroprene rubber, polychloroprene or chlorobutadiene rubber, which is mounted on the base plate, the impact of the hardcoated to be bonded on the base plate is better damped and damage to the hardcovers avoided.

When the first folding strip and the second folding strip are attached to the base plate from below such that a portion between the first end of the first folding strip and the second folding strip remains free, the edge folding unit can be used for finishing hardcuts twice larger than them itself is (the longer dimension of the hardcovers is crucial), because the hardcover provided for finishing can be turned over.

If the attachment is realized such that also a region remains free between the second end of the first folding strip and the second folding strip, the edge folding unit can be used for the finishing of indefinitely large hardcuts, since the edge folding can be carried out in sections over the entire length of the hardcovers ,

According to a second aspect, the hardcover device according to the invention comprises a work surface which has a light table provided with passports and a positioning unit of the cover reinforcements for adhering the cover reinforcements to a cover sheet positioned on the work surface, and additionally an edge folding unit fastened or fastened on the front side of the work surface of the hardcover device the first aspect of the invention. Such a hardcover device can be realized much more easily mechanically, because the edge folding unit can be realized without hinged at their ends, rotatable rollers, their suspension and regulation.

If there is a difference in height between the upper edge of the first folding strip and / or the second folding strip and the surface of the work surface, which is selected such that the surface of the work surface is higher, the pre-glued hardcover can be brought better into the edge folding unit. At the same time, the use of an attachable to the side of the hardcover device angle cutter for forming the corners of the pre-glued hardcovers is possible.

The edge folding unit 102 is preferably a fixed or detachable part of the hardcover device 101 , The hardcover device 101 at which the edge folding unit 102 is attached is in 1 with the reference number 100 characterized.

The hardcover device 101 can be any in the '638 or '684 Application described in our H32 Pro hardcover device or be another, with which preferably on a cover sheet containing pressure-active adhesive, lid reinforcements and possibly also a back insert can be attached. Below we will use our H32 Pro hardcover device as an example of the hardcover device 101 ,

The other of ours in the registrations '638 and '684 Hardcover devices described differ from our H32 Pro hardcover device mainly in the realization of the positioning unit, if the respective Kantenfalzeinheit is disregarded. For this reason, the following construction and operation of the positioning unit of the hardcover device 101 can be replaced with any positioning unit shown in our '638 or' 684 applications or with any other type of cover reinforcement and spine insert positioning.

The hardcover device 101 includes a work surface 120 in which there is a light table 140 located, the passport 141 having.

Additionally includes the hardcover device 101 a positioning unit that has a support surface 142 for the lid reinforcements and the back insert, as well as Passer 143 for fitting and holding the lid reinforcements and the back liner in the proper position during the bonding operation. The distance of the passer 143 from each other and the location relative to the light table 140 can with the help of locking screws 144 to be changed. The locking screws 144 are in a shake 145 movable back and forth.

The positioning unit is by means of a hinge 116 swiveling upwards so that from the work surface 120 as much as possible remains free.

The lid bow 94 will work on the desktop 120 positioned and with the help of the lid bow 94 and the hard disk device 101 existing passport 141 fitted in the right place.

Thereafter, the positioning unit is pivoted down so that the passer 143 closer to the lid bow 94 come. At this point at the latest, the passer 143 with the help of the locking screws 144 moved to the desired location in the lateral direction.

Thereafter, the left lid reinforcement 91 , the back insert 92 and the right lid reinforcement 93 on the support surface 142 placed.

Then the positioning unit is pivoted even further down until the left lid reinforcement is reached 91 , the back insert 92 and the right lid reinforcement 93 almost on the lid bow 94 be glued. At this point, the user pulls the left lid reinforcement 91 , the back insert 92 and the right lid reinforcement 93 a bit away from the support surface 142 until one by one on the lid bow 94 glue. The end result is a pre-glued hardcover according to 9 ,

The edge folding unit 102 includes an inner rabbet 103 and an outer folding strip 104 , The folding strips 103 . 104 are on a synthetic rubber pad 180 mounted on a base plate 105 is appropriate. The synthetic rubber pad 180 can be omitted if no damping is needed.

The base plate 105 the edge folding unit 102 is made by folding from thin sheet metal. For fastening the folding strips 103 . 104 holes are made in the thin sheet. In 1 are in the base plate 105 attached sheeps 106 for fastening the adjustable folding strip 104 shown. The permanently installed folding strip 103 can be done by simple holes on the base plate 105 be attached.

The cross section of the folding strips 103 . 104 Elsewhere, at the closed ends, it has the shape of an inverted U-letter, which is evident from the cross section XVIII-XVIII. The most advantageous dimensioning of the folding strips is e = 30 mm and f = 30 mm. As dimensioning e, f, a value deviating by 5 mm in both directions from 30 mm can also be used.

The folding strips 103 . 104 are fixed such that in the attached in the upper part of the inverted U-profile holes press screws 108 be attached. Inside the U-profile is a mounting sleeve 109 in the place of the press screws 108 appropriate. The folding strip 104 is from below the base plate 105 with the help of a finger screw extension 110 and a finger screw 111 on the base plate 105 fastened by the finger screw extension 110 in the mounting sleeve 109 and the finger screw 111 in the finger screw extension 110 is screwed. The folding strip 103 can be fixed accordingly or by using a conventional screw if the attachment is not made by using thumbscrews 111 to be realized.

Before attaching the folding strips 103 . 104 however with a fabric 201 according to 2 and cross-section XIX-XIX coated.

With the in 19 illustrated way is the fixation of the tissue 201 preferably before the positioning of the mounting sleeves 109 realized as follows: on both feet of the inverted U-profile, preferably at the lower part of the foot, a Velcro fastener tape 1910 attached. After that, the in 20 as a cross-section shown tissue 201 , at the ends of a Velcro tape 2010 is attached to the respective folding strip 103 . 104 fastened by the velcro straps 2010 on the Velcro straps 1910 be attached. As Velcro tapes 1910 . 2010 For example, hook-and-loop fastener tapes of any type may be used, for example, those having a hard barbed side and a soft looped side, or those having ball-headed outgrowths on both sides. The hard barb side is preferably inside the inverted U-profile as Velcro tape 1910 and the soft loop side as Velcro tape 2010 on the tissue 210 attached.

Out 19 also comes out as the folding strips 103 . 104 elastic can be made: to the folding strips 103 . 104 will be on the side that is between the folding strips 103 . 104 the inverted U-profile remains on the outside, a strip 1900 made of synthetic rubber. The synthetic rubber strip 1900 is preferably fixed just below the rounding resulting from the folding.

4 . 5 och 6 show the to the hardcover device 101 mounted edge folding unit 102 seen from the front, from above and from the side. The width of the slot 50 that is between the inner rabbet 103 and the outer rabbet 104 remains, c. 4 and 6 also show the feet of the device 401 of the hardcover device 100 , When the edge folding unit 102 on the hardcover device 100 and the feet 401 resting on the table are in the edge folding unit 102 thus no own device feet necessary.
