Definitions
- the invention relates to a device for opening folders of the kind that is seen in the preamble of claim 1 and described in WO 91/04934 .
- SE-C-464757 or WO 91/04934 describes a device by means of which folders can be opened during controlled transportation piece by piece, for feeding one or more supplements into an opened folder.
- an endless conveyor carrying generally V-shaped pockets, each one of which receives a folder, the back of the folder being placed in the bottom of the pocket.
- At the outer free border part thereof, at least one wall of the pocket has one or more controllable clips for gripping of one tail part of the opened folder.
- said folders are formed so that one half thereof is somewhat longer than the other half as counted from the back.
- the clips can only grip the outermost end of the longer half of the folder, and in this way, the shorter half of the folder can be turned away from the longer half of the folder, for instance, by the fact that the pocket is turned so that the shorter half of the folder, under the action of the gravity, will rest against the adjacent wall of the pocket.
- the shorter half of the folder may also be gripped by means of additional controllable grippers on the adjacent other pocket wall.
- One or more supplements can now be fed into the accordingly opened folder.
- a gripper clip at the bottom of the pocket to retain the folder in the pocket, when the pocket has such an orientation (for instance, facing downward) that there is a risk that the folder otherwise could fall out of the pocket.
- a folder conveyor having such clips or controllable grippers may run synchronously with the pocket conveyor.
- each folder is a critical part of the process.
- said folders may consist of newspapers that come from a newspaper press with a flow of 10-15 newspapers per second, and then it may be desirable to carry out 10-15 folder opening operations per second to be able to supply each newspaper in the flow from the press with one or more supplements. Even if the insertion process is carried out on a flow of newspapers off-line, it is desirable to be able to carry out the folder opening at a correspondingly high pace.
- an object of the invention is to provide a technique that allows opening folders at a folder-tail edge at a high pace, while said folders are transported piece by piece by a conveyor at a high flow, also when the folder sheets are entirely overlapping at the folder tail.
- DE-A-1436585 reveals an insertion technique in which folders, during separate transportation in the respective pockets, are opened for insertion by clamping the folder against a pocket wall and by sticking a wedge into the side edge of the folder at a preselected distance from the supporting pocket wall.
- the folder can be opened at a well-determined position, even if the sheets of the folder are mutually equal and entirely overlap each other.
- a drawback is that the wedge only can have a small width, and that the gap between the folder pages, in the area where the wedge is stuck in, only slowly propagates along the free folder edges, since the wedge should have a small wedge angle and therefore has to be introduced far into the folder to cause a propagation of the gap.
- US 3,450,400 A shows an apparatus for stuffing printed matter with at least one insert or supplement, where an opening action is exerted by applying an opening force to a lateral open edge along the thickness of the jacket section.
- EP 0,596,581 A2 shows a device for opening the pages of a printed product by separation of edges of a group of pages.
- US 2004/0061271 A1 shows an opening device for selectively opening folded printed products.
- the object is attained by the invention.
- the invention relates to a device for opening folders during transportation comprising a folder conveyor having an endless chain having folder pockets that are arranged mutually equidistantly and have a leading wall each running ahead in the direction of transportation and, at a free edge, having at least one clip for clamping a tail portion of a folder part against said leading wall, openers being arranged to run each close to the free edge of the leading wall of a pocket along at least a part of the path of motion thereof, each opener comprising a clamping jaw arranged to clamp the folder against a support, and a wedge that has a tip and that is displaceable for introducing the tip into a tail end of the folder at a selected distance from the support.
- the wedge has two guide edges that diverge from the wedge tip in a direction opposite the drive-in direction of the wedge into the folder, away from each other in the plane of the folder, as well as away from the support so that a folder part deflected upon the driving-in of the wedge is supported by the two guide edges thereby allowing the two non-deflected folder tail parts to be exposed in order to be fixed to the leading wall of the pocket by the at least one clip.
- the clamping jaw of the opener is preferably arranged to be biased against the support in order to hold together the folder tail in the central part thereof where the wedge tip is driven-in.
- the wedge is driven-in so that the two guide edges thereof support the deflected folder part in separated positions along the folder tail, and at a distance from the folder edge (within the extension area of the folder), while the clamping jaw holds the folder compressed at the folder-tail edge.
- the deflected folder part will, along the folder tail, form two triangular parts, the tips of which are situated at the transversally central edge of the folder tail and at the clamping jaw.
- the opener may also comprise additional clamping jaws that are pressed against the folder (and offer a clamping of the folder against the leading wall) at a position above the deflection line of the triangular folder part that, in that connection, is established in the maximally introduced state of the wedge.
- said additional clamping jaws are separated from the central part centre of the folder, on both sides thereof.
- the clip of the leading wall may be reliably pressed against the folder part situated closest to the leading wall.
- the continued opening of the folder may, for instance, be effected such as has been disclosed in connection with the device according to SE-C-464757 .
- the insertion into, and the transportation away of the folder including input supplements can also be effected according to prior art, for instance, such as it is seen in SE-C-464757 .
- the device according to Figs. 1-4 corresponds substantially to the one according to Figs. 1-4 in SE-C-464757 , but has in Figs. 1 and 2 been supplemented with an additional conveyor 90 that carries openers according to the invention for folders transported in the insertion apparatus.
- a conveyor 90 is also shown in connection with the apparatus illustrated in Fig. 5 .
- a folder 20 see for example Figs. 3 and 4 , has a "back” and a "tail".
- the "back” is the portion of the folder20 being held by the gripper 45 or 45' see Figs. 1 to 5 .
- the "tail” 24 is the opposite edge of the folder 20 which in Figs. 1 , 4 and 5 is illustrated as being fixed to the leading front wall 21 by the clip 23.
- Fig. 1 schematically illustrates an endless conveyor 10 comprising a chain 11 that runs over two chain wheels 12, 13, at least one of which is driven for rotation in the direction indicated.
- the conveyor 10 contains two equal parts displaced in the axial direction of the wheels 12, 13, each one of the parts is a series of pockets 14 that mouth outward away from the chain 11 and extend transverse to the longitudinal direction of the chain 11.
- Each pocket 14 consists of a leading wall 21 and a trailing wall 22, and a clip 23 at the outer end of the leading wall 21.
- An endless conveyor 40 has controllable grippers 45 at a mutual distance, corresponding to the distance between adjacent pockets 14 of the chain 10.
- the endless conveyor 40 is guided by a shown guide, so that the grippers 45 run along and close by the path of the chain 11 along a part of the running path thereof such as is shown.
- Each gripper 45 carries the back of a folder 20 and converges toward the chain 11 so that each folder is lifted into an appurtenant pocket.
- the endless conveyor 40 and the grippers 45 may leave the pockets by the fact that the endless conveyor 40 diverges from the conveyor 10. While the pockets are turned substantially over the horizontal plane, the grippers 45 can be opened.
- a supplement 61 can be fed out from a storage 60 and be introduced into an opened folder in a pocket that is facing upward so that the gripper 45 in question can be open, whereby the supplement 61 can be introduced up to the back of the folder and thereby reliably be retained in the folder during further transportation by means of the gripper 45.
- the conveyor 40 may be a conveyor that picks up the folders (newspapers) from a printing press or the corresponding production area.
- Fig. 5 shows an embodiment where the grippers 45' are fixedly attached on the conveyor 10 at the bottom area of the pockets.
- folders 20 are fed down into passing pockets by means of a feeding-in device 200.
- two feeding-in devices 62, 63 are shown for supplements, and in addition, a device 70 is illustrated that after the opening of the clip 23 closes the folder including supplements and puts the folder in a predetermined position, for instance, so that it abuts against the trailing rear wall 22 of the pocket 14.
- an unloading conveyor 80 having grippers 83 can work synchronously with the conveyor 10 and grip the closed folders including the supplements in the tail for transportation away.
- an endless conveyor 90 carries openers 91, which have a mutual distance corresponding to the pitch between the pockets 14, the conveyor 90 being synchronized with the conveyor 11 so that an opener 91 is placed close by the outer end of the leading wall 21 of each pocket 14 and synchronously accompanies the same a chosen distance.
- Figs. 2-4 illustrate that the conveyor 11 may contain two mutually equal conveyor parts 14a and 14b, wherein the grippers 45 may run between said parts 14a, 14b.
- the gripper comprises a support chute 46, the bottom line 50 of which corresponds to the bottom line of the pockets 14.
- the grippers 45 further comprise a movable clamping jaw 48, which co-operates with a stationary clamping jaw 47 that is shown to be a wall in the pocket.
- the walls of the pockets may be mounted around spindles 49 at the bottom of the pocket, and furthermore, the walls of the pockets may be provided with drivers 25, 26 that co-operate with control members that control the turning motion of the walls 21, 22 during transportation, if desired.
- the opener conveyor 90 may be assumed to be located between the conveyor parts 10a, 10b, such as is illustrated in Fig. 2 .
- Fig. 6 schematically illustrates an opener 91 of the conveyor 90.
- the tail end 24 of a folder 20 can be seen.
- the folder 20 abuts against the leading wall 21, which lies in the plane indicated.
- the opener 91 comprises a body 94, which is fitted into the transportation chain 92. Via a pivot mounting 109, the body 94 carries an arm 110, which at one end is provided with a support plate 111 and on the other end with a tracer 112, for instance, a tracer roller that is guided by a guiding path, so that the support plate 111 can be put under in order to allow the folder tail 24 to come into and out of the position shown without being blocked by the support plate 111.
- a tracer 112 for instance, a tracer roller that is guided by a guiding path
- the support plate 111 should assume an exact end position, which is shown in Fig. 6 and which preferably lies in the vicinity of the plane indicated.
- the body 94 carries via a pivot mounting 119 an arm 120, which is turnable into and out of the shown position.
- the arm 120 is shown to carry a clamping jaw 121, which is connected to the arm 120 via a pivot mounting 122.
- a spring 123 resting against the arm 120 biases the clamping jaw 121 into an outer end position.
- the pivot mounting 122 and the spring 123 allow the clamping jaw 121 to assume end positions at different distances from the support plate 111 when the arms 110, 120 have assumed the end positions thereof shown.
- the arm 120 may be turned around the mounting 119 into a folded-away position to allow the folder tail 24 to be easier introducable into the shown position in relation to the body 94.
- the arm 120 is shown to have a tracer 124, for instance, in the form of a roller, which is guided by an appurtenant guiding path, not shown, which is formed to bring about the different turning positions of the arm 120 during transportation.
- a tracer 124 for instance, in the form of a roller, which is guided by an appurtenant guiding path, not shown, which is formed to bring about the different turning positions of the arm 120 during transportation.
- the arm 120 of the opener and possibly also the arm 110 can be turned away to allow the opener to diverge away from the path of motion of the pockets, without mutual interference.
- the free folder part 20B comes into abutment against the trailing wall 22 (see Fig. 5 ) and turns up toward the horizontal plane, i.e., at the left end of the conveyor according to, for instance, Fig. 5 .
- a clip (not shown) at the outer edge of the trailing wall 22 can then clamp the tail end of the free folder part 20B in a known manner per se , if it is desirable to hold both end edges of the folder parts 20A, 20B retained at the pocket walls during an insertion operation.
- the conveyor 90 comprises an endless transportation chain 92 that runs around two chain wheels 93, at least one of which is driven.
- One run of the chain extends along the path of motion of the free edges of downwardly turned pockets, and the pitch between the openers 91 corresponds to the pitch between the pockets 14.
- the body 94 is shown to have a guide 130 for a bar 131, which thereby is movable in a direction parallel to the support surface of the support plate 111 and thereby parallel to the main surface of the folder.
- the bar 131 is, at one end thereof, provided with a wedge 132, having a leading lip 134 (see Fig. 13 ).
- the leading lip 134 is preferably parallel to the support surface of the support plate 111 and essentially perpendicular to the linear direction of motion of the bar 131.
- the front surface 133 of the wedge 132 that is facing the support plate 111 is preferably parallel to the support surface of the support plate.

Abstract
Description
- The invention relates to a device for opening folders of the kind that is seen in the preamble of claim 1 and described in
WO 91/04934 -
SE-C-464757 WO 91/04934 - According to a technique known from practice, said folders are formed so that one half thereof is somewhat longer than the other half as counted from the back. The clips can only grip the outermost end of the longer half of the folder, and in this way, the shorter half of the folder can be turned away from the longer half of the folder, for instance, by the fact that the pocket is turned so that the shorter half of the folder, under the action of the gravity, will rest against the adjacent wall of the pocket. Possibly, the shorter half of the folder may also be gripped by means of additional controllable grippers on the adjacent other pocket wall. One or more supplements can now be fed into the accordingly opened folder.
- Possibly, there may be a gripper clip at the bottom of the pocket to retain the folder in the pocket, when the pocket has such an orientation (for instance, facing downward) that there is a risk that the folder otherwise could fall out of the pocket.
- A folder conveyor having such clips or controllable grippers may run synchronously with the pocket conveyor.
- The opening of each folder is a critical part of the process. In practice, said folders may consist of newspapers that come from a newspaper press with a flow of 10-15 newspapers per second, and then it may be desirable to carry out 10-15 folder opening operations per second to be able to supply each newspaper in the flow from the press with one or more supplements. Even if the insertion process is carried out on a flow of newspapers off-line, it is desirable to be able to carry out the folder opening at a correspondingly high pace.
- Therefore, an object of the invention is to provide a technique that allows opening folders at a folder-tail edge at a high pace, while said folders are transported piece by piece by a conveyor at a high flow, also when the folder sheets are entirely overlapping at the folder tail.
-
DE-A-1436585 reveals an insertion technique in which folders, during separate transportation in the respective pockets, are opened for insertion by clamping the folder against a pocket wall and by sticking a wedge into the side edge of the folder at a preselected distance from the supporting pocket wall. In this way, the folder can be opened at a well-determined position, even if the sheets of the folder are mutually equal and entirely overlap each other. A drawback is that the wedge only can have a small width, and that the gap between the folder pages, in the area where the wedge is stuck in, only slowly propagates along the free folder edges, since the wedge should have a small wedge angle and therefore has to be introduced far into the folder to cause a propagation of the gap. When the gap eventually has become opened also at the tail of the folder, a thread of a screw is introduced between the opened folder portions in order to further separate the same and hold them apart during the following transportation of the folders to a station where a supplement is introduced into the opened folder. The technique according toDE-A-1436585 is slow by nature and can therefore not be used for the purpose according to the invention. -
US 3,450,400 A shows an apparatus for stuffing printed matter with at least one insert or supplement, where an opening action is exerted by applying an opening force to a lateral open edge along the thickness of the jacket section. -
EP 0,596,581 A2 shows a device for opening the pages of a printed product by separation of edges of a group of pages. -
US 2004/0061271 A1 shows an opening device for selectively opening folded printed products. - The object is attained by the invention.
- The invention is defined in the appended claims.
- Thus, in one embodiment, the invention relates to a device for opening folders during transportation comprising a folder conveyor having an endless chain having folder pockets that are arranged mutually equidistantly and have a leading wall each running ahead in the direction of transportation and, at a free edge, having at least one clip for clamping a tail portion of a folder part against said leading wall, openers being arranged to run each close to the free edge of the leading wall of a pocket along at least a part of the path of motion thereof, each opener comprising a clamping jaw arranged to clamp the folder against a support, and a wedge that has a tip and that is displaceable for introducing the tip into a tail end of the folder at a selected distance from the support.
- The wedge has two guide edges that diverge from the wedge tip in a direction opposite the drive-in direction of the wedge into the folder, away from each other in the plane of the folder, as well as away from the support so that a folder part deflected upon the driving-in of the wedge is supported by the two guide edges thereby allowing the two non-deflected folder tail parts to be exposed in order to be fixed to the leading wall of the pocket by the at least one clip. The clamping jaw of the opener is preferably arranged to be biased against the support in order to hold together the folder tail in the central part thereof where the wedge tip is driven-in. The wedge is driven-in so that the two guide edges thereof support the deflected folder part in separated positions along the folder tail, and at a distance from the folder edge (within the extension area of the folder), while the clamping jaw holds the folder compressed at the folder-tail edge. In this way, the deflected folder part will, along the folder tail, form two triangular parts, the tips of which are situated at the transversally central edge of the folder tail and at the clamping jaw. In order to further support a controlled turning-up of the triangular edge portions of the deflected folder part, the opener may also comprise additional clamping jaws that are pressed against the folder (and offer a clamping of the folder against the leading wall) at a position above the deflection line of the triangular folder part that, in that connection, is established in the maximally introduced state of the wedge. Thus, said additional clamping jaws are separated from the central part centre of the folder, on both sides thereof. In the areas below the bent-up triangular folder parts, the clip of the leading wall may be reliably pressed against the folder part situated closest to the leading wall. The continued opening of the folder may, for instance, be effected such as has been disclosed in connection with the device according to
SE-C-464757 SE-C-464757 - An embodiment of the invention will now be described by way of examples, reference being made to the appended drawing.

folder 20, see for exampleFigs. 3 and 4 , has a "back" and a "tail". The "back" is the portion of the folder20 being held by thegripper 45 or 45' seeFigs. 1 to 5 . The "tail" 24 is the opposite edge of thefolder 20 which inFigs. 1 ,4 and5 is illustrated as being fixed to the leadingfront wall 21 by theclip 23. -
Fig. 1 schematically illustrates anendless conveyor 10 comprising achain 11 that runs over twochain wheels conveyor 10 contains two equal parts displaced in the axial direction of thewheels pockets 14 that mouth outward away from thechain 11 and extend transverse to the longitudinal direction of thechain 11. Eachpocket 14 consists of a leadingwall 21 and a trailingwall 22, and aclip 23 at the outer end of the leadingwall 21. Anendless conveyor 40 hascontrollable grippers 45 at a mutual distance, corresponding to the distance betweenadjacent pockets 14 of thechain 10. Theendless conveyor 40 is guided by a shown guide, so that thegrippers 45 run along and close by the path of thechain 11 along a part of the running path thereof such as is shown. Eachgripper 45 carries the back of afolder 20 and converges toward thechain 11 so that each folder is lifted into an appurtenant pocket. Correspondingly, theendless conveyor 40 and thegrippers 45 may leave the pockets by the fact that theendless conveyor 40 diverges from theconveyor 10. While the pockets are turned substantially over the horizontal plane, thegrippers 45 can be opened. Asupplement 61 can be fed out from astorage 60 and be introduced into an opened folder in a pocket that is facing upward so that thegripper 45 in question can be open, whereby thesupplement 61 can be introduced up to the back of the folder and thereby reliably be retained in the folder during further transportation by means of thegripper 45. Theconveyor 40 may be a conveyor that picks up the folders (newspapers) from a printing press or the corresponding production area. -
Fig. 5 shows an embodiment where the grippers 45' are fixedly attached on theconveyor 10 at the bottom area of the pockets. In this case,folders 20 are fed down into passing pockets by means of a feeding-indevice 200. Furthermore, two feeding-indevices device 70 is illustrated that after the opening of theclip 23 closes the folder including supplements and puts the folder in a predetermined position, for instance, so that it abuts against the trailingrear wall 22 of thepocket 14. In this way, an unloadingconveyor 80 havinggrippers 83 can work synchronously with theconveyor 10 and grip the closed folders including the supplements in the tail for transportation away. - In
Figs. 1 and5 , it can be assumed, that the pockets, as facing downward, have, the leadingwalls 21 thereof situated approximately in the vertical plane, so that the unopened folder tends to lie next to thiswall 21. It can be seen that anendless conveyor 90 carriesopeners 91, which have a mutual distance corresponding to the pitch between thepockets 14, theconveyor 90 being synchronized with theconveyor 11 so that anopener 91 is placed close by the outer end of the leadingwall 21 of eachpocket 14 and synchronously accompanies the same a chosen distance. -
Figs. 2-4 illustrate that theconveyor 11 may contain two mutuallyequal conveyor parts grippers 45 may run between saidparts - In
Fig. 3 , it can be seen that the gripper comprises asupport chute 46, thebottom line 50 of which corresponds to the bottom line of thepockets 14. Thegrippers 45 further comprise amovable clamping jaw 48, which co-operates with astationary clamping jaw 47 that is shown to be a wall in the pocket. Possibly, the walls of the pockets may be mounted aroundspindles 49 at the bottom of the pocket, and furthermore, the walls of the pockets may be provided withdrivers walls - The
opener conveyor 90 may be assumed to be located between theconveyor parts 10a, 10b, such as is illustrated inFig. 2 . -
Fig. 6 schematically illustrates anopener 91 of theconveyor 90. InFig. 6 , thetail end 24 of afolder 20 can be seen. Thefolder 20 abuts against the leadingwall 21, which lies in the plane indicated. Theopener 91 comprises abody 94, which is fitted into thetransportation chain 92. Via a pivot mounting 109, thebody 94 carries anarm 110, which at one end is provided with asupport plate 111 and on the other end with atracer 112, for instance, a tracer roller that is guided by a guiding path, so that thesupport plate 111 can be put under in order to allow thefolder tail 24 to come into and out of the position shown without being blocked by thesupport plate 111. Furthermore, thesupport plate 111 should assume an exact end position, which is shown inFig. 6 and which preferably lies in the vicinity of the plane indicated. In addition, thebody 94 carries via a pivot mounting 119 anarm 120, which is turnable into and out of the shown position. Thearm 120 is shown to carry aclamping jaw 121, which is connected to thearm 120 via a pivot mounting 122. A spring 123 (seeFig. 9 ) resting against thearm 120 biases the clampingjaw 121 into an outer end position. The pivot mounting 122 and thespring 123 allow theclamping jaw 121 to assume end positions at different distances from thesupport plate 111 when thearms - The
arm 120 may be turned around the mounting 119 into a folded-away position to allow thefolder tail 24 to be easier introducable into the shown position in relation to thebody 94. - The
arm 120 is shown to have atracer 124, for instance, in the form of a roller, which is guided by an appurtenant guiding path, not shown, which is formed to bring about the different turning positions of thearm 120 during transportation. - The
arm 120 of the opener and possibly also thearm 110 can be turned away to allow the opener to diverge away from the path of motion of the pockets, without mutual interference. Thefree folder part 20B (seeFig. 5 ) comes into abutment against the trailing wall 22 (seeFig. 5 ) and turns up toward the horizontal plane, i.e., at the left end of the conveyor according to, for instance,Fig. 5 . A clip (not shown) at the outer edge of the trailingwall 22 can then clamp the tail end of thefree folder part 20B in a known manner per se, if it is desirable to hold both end edges of thefolder parts - In, for instance,
Fig. 5 , it can be seen that theconveyor 90 comprises anendless transportation chain 92 that runs around twochain wheels 93, at least one of which is driven. One run of the chain extends along the path of motion of the free edges of downwardly turned pockets, and the pitch between theopeners 91 corresponds to the pitch between thepockets 14. - Furthermore (see
Fig. 6 ), thebody 94 is shown to have aguide 130 for abar 131, which thereby is movable in a direction parallel to the support surface of thesupport plate 111 and thereby parallel to the main surface of the folder. Thebar 131 is, at one end thereof, provided with awedge 132, having a leading lip 134 (seeFig. 13 ). The leadinglip 134 is preferably parallel to the support surface of thesupport plate 111 and essentially perpendicular to the linear direction of motion of thebar 131. Thefront surface 133 of thewedge 132 that is facing thesupport plate 111 is preferably parallel to the support surface of the support plate. Thebar 131 is shown to have atracer 139, in the form of a roller that is guided by a guiding path (not shown) along the path of motion of the opener and the pocket, whereby thebar 131 is imparted a chosen reciprocating motion by which thewedge 132 is driven into thefolder tail 24. In this way, thewedge 132 initiates an opening of thefolder tail 24. By adjusting the distance along the chain of theconveyor 90 between thesupport plate 111 and thewedge 132, it is possible to exactly select the position for the penetration of the wedge into the folder tail, i.e., between which pages the folder should be split. Thewedge 132 penetrates into thefolder tail 24 between thesupport plate 111 and the spring-loadedclamping jaw 121. InFig. 9 , it can be seen that the clampingjaw 121 holds together the folder tail also when thewedge 132 with the shank thereof connecting thereto is driven into the folder tail. -
Figs. 6 ,11 , it can be understood that thewedge 132 has atip 138 that is thin and has a leading lip 134 (seeFig. 13 ) that is parallel to the extension plane of the folder. Thewedge 132 has furthermore twoarms 136 that extend toward opposite directions from the tip part, and away from the plane defined by the leadingwall 21. Thearms 136 have, on the upper sides thereof facing the folder tail, aguide edge 137 each. Said guide edges extend from thetip 138 and are substantially symmetrically diverging out of the plane of the leadingwall 21 and away from the tip and thebar 131 that is shown to extend in the displacement direction of the wedge. Thewedge 132 is shown to be carried by thebar 131 that lies in a symmetry plane to the wedge, and the guide edges 137 are accordingly mirror-symmetrical in relation to said plane. By the fact that thearms 136, in the portions thereof closest to thebar 131, extend substantially in the plane of the folder and not until at a relatively great distance from thebar 131 have portions that extend transverse to the plane of the folder, such that a tail part of thefolder 20 due to the interaction with the guide edges 137 will be deflected a relatively great distance out of the plane in which thewedge tip 138 is arranged. The guide edges 137 try to roll up the outerfolder tail part 24A when the guide edges 137 reach a level above the folder tail as viewed inFig. 7 , and since the effective parts of the guide edges 137 are at a relatively great distance from each other, a stable bending-up of the outerfolder tail part 24A can be attained. In this position, theclips 23 can be driven into engagement with thefolder tail part 24B. By the fact that the clampingjaw 121 and thesupport 111 hold together the folder tail all the way to the lower edge thereof, also when the central part of thewedge 132 is introduced in the intermediate folder tail part, the bent-up outerfolder tail parts 24A will assume the shape of triangular tongues, such as is shown inFig. 8 . In this way, the bent-up outerfolder tail parts 24A are further stabilized. Possibly one may, such as is schematically illustrated at 144 inFig. 8 , temporary press supporting shoulders against the free main surface of the folder in the area above the bent-up outerfolder tail part 24A and so that the same experience an additional stabilization during the period of time when theclip 23 should be pressed. As soon as theclips 23 have gripped thefolder tail parts 24B, thewedge 132 can be retracted and the opener has fulfilled the work thereof. InFig. 13 , it can be seen that thewedge tip 138 has a small width and a sharpleading lip 134 extending parallel to the extension plane of the folder, the side of the wedge tip facing the leadingwall 21 being parallel to the same while thecorresponding surface 135 of the wedge tip converges in relation to thefront surface 133 toward the leadinglip 134.
