The present invention relates to an automatic method for producing a tear-through arrangement that can be processed endlessly, which comprises a continuous web and sticker and a device for carrying out the method.

In the following, the term "scrolling arrangement to be processed endlessly" is used both with individual forms, labels or the like. provided endless goods, e.g. endless forms as well as a endless single track with carbon-copy fittings arranged on this, especially multiple forms.

Today there are no machines or methods suitable for practical use for producing such endlessly processable ones Known copy arrangements. So far the production has taken place such arrangements in an artisanal manner, resulting in insufficient production and insufficient accuracy brought.

The present invention aims to overcome these drawbacks by creating a process that is characterized by the fact that the endless web is in one direction and moves the stickers in the opposite direction towards each other and connects them together and then arranges them.

The invention will then be explained using figures, for example.
Show it:

Pig. 1 is a view of a machine for applying individual forms, Addresses or the like on endless forms or from sets to endless individual lanes,

FIGS. 2-6 show, in a purely schematic representation, a part of the machine according to FIG. 1 in different positions the various process steps when attaching clothing to a guide belt,

7 shows a schematic representation of a plan view of a Part of the machine according to Fig. 1,

8 shows a section along section line AA in FIG. J ₃ and FIG. 9 shows a section along section line BB in FIG.

The machine shown in FIGS. 1-7 has a support 1 for a guide band pulled from a guide band stack 3 4, which is provided with edge perforations, with the help of which the guide belt 4 is conveyed. Above the stack of guide belts 3 there is an adjustable deflection rod 5 which, viewed in the direction of movement of the guide belt, is a gluing station 7 follows. This is followed by a placement and pressing station 9. A device is used to hold a Stack 11 of stickers 12, designed as sets, which are intended to be glued onto the guide strip 4. One Transport device 13 is used to pull the sticker 12 out of the Star..el 11 and to the application and pressing station 9 bring ai. It is also a tiltable Pneumostation 15 with Suction and blown air are provided for separating the individual stickers 12 from the stack 11. After the application and pressing station 9 a cyclically working transport device is arranged followed by a depositing device 17, which stuck the belt runs through and then on a height-adjustable

automatically lowerable tray 19 arrives. The machine is operated by means of switches arranged on a switch box 21 served. Among the stations mentioned is in Pig. I covered by cover plates, a gear box with gear and drive for advancing the guide belt 4 in cycles.

The machine shown in Fig. 1 works with two side by side running tracks. Slidable bearings 26, in which a pivot shaft 27 is mounted, are attached to the machine frame is. Nozzle carriers 29 with exchangeable glue nozzles 30 are clamped onto this shaft 27. A central, height-adjustable The glue container 32 supplies the nozzles 30 with glue via a hose 33. By adjusting the height of this glue container 32 the glue inflow and thus the glue application can be changed, for example as a result of different materials. A rooster 34 in the supply hose 33 can with longer interruptions or when changing nozzles 30, block the outflow of glue. The supply hose 33 opens into a distributor pipe 36, from which lead the individual connection hoses 37 to the nozzles 30.

Instead of point gluing using individual nozzles, line gluing over the entire width of the form or a Part of the same are provided. It must then be ensured before each advance of the guide belt that all parts, such as stops or the like. Are lifted to prevent erosion of the glue point.

309818/0649

The application and pressing station 9 comprises bearings 39 with a pivot shaft 40 on which press fingers 41 can be adjusted are attached. One or more of these pressing fingers 4l are equipped with a leaf spring 42. On a Further pivotable shaft 43 are two stop heads 44 with guide slots 45 and stop surfaces 46 per track arranged for the sticker 12 to be applied. Under "sticker" is a single form, a label or the like., which is applied, for example, to a set of continuous forms, or a set of forms that you put on a carrier or guide tape, understood. Form sets are also called Designated sets. Above these parts there is a stand 48 with a fixed support 49 on which means of a bolt 51, a yoke beam 50 is pivotally attached. A programmatically controlled ram that can be raised and lowered is connected to the yoke beam 50. On both sides of the yoke beam 50 is also by means of a shaft 55 each one transverse to the feed direction displaceable pivot arm 54 attached, its location therefore the width of the sticker can be adjusted. The swivel arm 54 is equipped with a double-stroke electromagnet 56, which actuates a pair of pliers 57 having an upper fixed clamp 58 and a lower pivotably movable clamp 60 serves. This clamp 60 is attached to a pivot shaft 6l. It is also equipped with a tab 62. By two tabs 62, a pin 63 is inserted, which the two pliers 57 belonging to a pivot arm 54 or the lower Klemmer 60 carries these pliers. A rod 64 is attached to the pin 63, the connection of which is via a ball joint

65 takes place. The upper part of the rod 64 passes through the electromagnet 56. It carries a spring at its free end

66 and a spring plate 67 which can be adjusted for the purpose of pretensioning the spring 66.

In order to prevent the stickers, e.g. in the form of sets, labels or the like tilt or tear through, the pliers 57 are attached between the two stop heads 44. The tongs 76 are not only transport organs, but also serve to position the forms to be glued on.

At the adhesive stacking table 10 is arranged dx ^ Pneurnostation 15, by means of which, as indicated, air is blown from below through the stacking table 10 in the direction of the arrows 69, such that the contact pressure of the stack 11 on the table 10 and thus the friction when pulling out the lowermost set 12 is reduced.

There are also suction cups 70 provided, which serve to pulling the head of the sticker 12, e.g. designed as a set, downward away from the stack 11. This becomes an air nozzle 71 given the possibility of blowing compressed air between the lowermost set 12 and the stack 11 above it. It can advantageously this air nozzle 71 at the same time as a holding finger for holding the over the set to be pulled out serve as a storage stack. In Fig. 3 a set 73 is shown

_ ₆ _ 3 09818/0649

placed that, opposite to the direction of movement 74 of the guide belt 4, is withdrawn from the stack 11 and placed on the preceding set 75, with an overlap 46 takes place. This overlap can only be achieved if, as explained, the clothing 73 is opposite to the direction of advance of the guide or carrier tape 4 moves. Before destacking the taped tapes is located under the tape 4 a driven roller 78 with two upper pressure rollers 79 slightly in front.

The tapping device also includes a swivel and Stirrup 81. The guide band 4 is located approximately in the middle, i.e. half the length of the set Middle fold 82, which allows, in the Pig. I can see the guide band 4 with the sets 12 so stack that the guide tape 4 is placed around the center fold 82, the head 83 of the set with the guide tape 4, the the other half of the set lies on the stack without a guide band. Accordingly, all sets are directed in the same way, i.e. lying congruently on top of one another.

When filing endless sets with stickers, the bracket 81 and the table 19 are not required. Such endless sets are guided over an edge, analogous to the edge of the storage table 19 in a container (not shown).

309818/0649

It is also possible to use the described machine on the delivery with a cream splicing device for cutting off the edges of the holes of webs, while when the web enters the machine, a cross perforation device and / or a punching device can be arranged. It can also be useful to have a numbering device on the delivery of the machine in order to number the forms, labels and the like consecutively after sticking them on.

The machine described above works as follows:

The guide belt 4 (it can also be an endless form to which individual forms, labels or the like are applied) withdrawn from the guide band stack 3 and moved from right to left in the figures. The clockwise movement is carried out by a in the edge perforations of the guide belt 4 engaging spiked belt. The feed length of the guide belt 4 or the web is each chosen according to the length of the set or the form or the size of the overlap 76 and with changing edges set. This construction therefore allows any desired feed length of the guide belt 4 or the path to be set.

After the feed has ended, the gluing station 7 comes into operation. The pivot shaft 27 with the nozzles 30 raised up to that point is pivoted counterclockwise so that the nozzles 30 open lower the guide belt 4. This results in one of the arrangements

30981 8/0649

the nozzles 30 corresponding, point-shaped gluing of the guide band. The contact time of the nozzles 30 on the guide belt 4 can be adjusted, which enables extremely precise regulation of the amount of glue dispensed by the nozzles. The pivot shaft is then pivoted clockwise, as a result of which the nozzles are lifted off the guide belt 4. Another one
Lifting off (by hand) allows easy cleaning of the nozzles

The guide belt drive is switched on again automatically and the guide belt 4 accordingly in a further cycle the laying and pressing station 9 pulled. The gluing station 7 repeats the gluing of the guide belt 4 or the endless clothing in the manner described above with each cycle.

During the gluing phase explained, the lowest
Set or the sticker 12 of the stack 11 by means of
Pneumostation 15, ie the blowing air 69 and the blowing nozzles 71 and the suction cups 70 have been prepared for removal.
The air nozzles 71 support the remaining stack
while pulling out the bottom set. In addition
When in operation, they swivel past the head of the bottom set under the stack. The two pliers 57 arranged between the stop heads 44 are in the open grip position as shown in FIG. In the last part of the pivoting movement in the direction of the stack 11, the head 83 of the sticker arrives

30981 8/0649

12 between the two clamps 58 and 60. At the end of the The electromagnet 56 becomes the pivoting movement of the tongs 57 controlled to close the pliers 57. The arm 54 then swivels back with the tongs 57, these Pull out a set 73 (FIG. 3) between the stack 11 and the stacking table 10 and press it against the guide belt 4 and bring the stop heads 44. According to FIG. 3, the swivel arm 54 reaches a lowest position from which it expands in the in Pig. 4 shown dead center swings out.

The connection of the rod 64 via the ball joint 65 ensures that the two tongs 57 are actuated evenly and regardless of the thickness, a simultaneous gripping of the clothing 12 is ensured.

Before this final phase of the swinging out of the swivel arm 54, the sticker 73 with its head 83 enters the guide slots 45 of the stop heads 44 Concern comes. Shortly before reaching the stop surfaces 46, the electromagnet 56 is de-energized, with the force of the spring 66 and the tongs 57 being held in a reduced clamping position which can be adjusted with regard to clamping force. After reaching the stop heads 44 are the

309818/0649

Pliers 76 removed from the adjacent stationary sticker. During the pulling of the pliers JG from the sticker, the pivot shaft 40 is pivoted in the bearings 39 in the counterclockwise direction, whereby the leaf spring k2 comes to rest on the sticker 73 and holds it in place. This prevents the set or the sticker 73 from being pecked back and its extremely precise contact is achieved. Subsequently, ie after the pliers 76 have been withdrawn from the sticker 73 _} , a second movement of the pivot shaft UO lowers the pressing fingers ¹ Jl, which exert a pressure at specific points over the entire gluing width of the head 83 of the set 73 and 12, respectively The pressing fingers 4l are placed exactly at the pre-glued points. By appropriate selection of a glue that sets under pressure, the head 83 of the set 73 or of the sticker is glued to the web, ie the guide tape 4, at the appropriate points.

In order to return the tongs 57 to their gripping position according to FIG. 2 after this positioning, after swinging out in the position according to FIG. 5 of the yoke beam 50 by lifting the Plunger 52 together with the swivel arm 5 ** and the pliers 57 something raised and then swiveled in a clockwise movement of the swivel arm 5 ^ into the gripping position. During this Movement, the tongs 76 are opened again by means of the electromagnet 56 and the pivot arm 5 ^ over the yoke beam 50 and the plunger 52 lowered.

The next set 12 can be grasped in the manner described and pulled onto the guide belt 4. So while the first gluing point of the guide belt 4 in the second described Cycle arrives in the placing and pressing station, the set or the sticker 12 is explained in the manner explained against the direction of movement of the guide belt 4 pulled into this station 9 and initially with the leaf spring 42 on the Tape or web 4 held. As explained, a second movement of the pivot shaft 40 now takes place with the lowering the press finger 4l and the gluing of stickers and guide tape.

Before the beginning of the next cycle with the shifting of the guide belt 4 is then the pivot shaft 40, in the present case by means of cam control (not shown), pivoted clockwise and thus both the pressing fingers 41 and the leaf spring 42 from the applied sticker or removed from the set 73. At the next feed or the next cycle, the stationary path or the guide belt becomes 4, glued again, while the corresponding set 73 or the sticker with the help of the lowered pressing fingers 4l is glued to the tape 4. The swivel arm 54 with the tongs 57 is already in place during the gluing and gluing comes back into its grip position, previously the yoke beam 50 again lowered by means of the ram 52 during the swing-back movement and returned to the correct gripping position.

was leading. Now the game repeats itself anew, during the advancing movement of the guide belt 4 described in FIG Way, the next set 12 or 73 pulled from the stack of clothing 11 and brought over the guide belt 4 or the web will. The end position is reached at standstill and both the leaf spring and the press finger provide the correct one Gluing the set on the guide tape securely. When the sets are glued to a guide tape 4, the tape 4 comes with it the glued sets between the driven roller 78 and the upper pressure rollers 79, where due to the location of the Pressure rollers 79 with respect to roller 78, the puss end of the Set 12 is pointed upwards, while the bracket 81 pivoted against the take-off roller 78 moves the guide belt 4 downwards leads. The guide band 4 is automatically folded around the center fold 82, as can be seen in FIG. 1. During this The swivel and stroking bar 81 is flipped over in the Pig. I. swiveled out in a clockwise direction, it grasps the set 12 and strokes it out, so that the lower Halves of these sets come to lie directly on top of one another. In this way, the guide tape 4 is stacked with the sets.

When working with stickers on continuous forms, the Storage as described earlier.

As mentioned, it is also possible to change the cycle length or the

occasional advance of the guide belt 4 according to the circumstances to adjust. Furthermore, instead of the sets, adhesive addresses or forms, labels and the like can be used on endless webs be applied. The machine always works in the manner described and all that is required is a corresponding one Adjustment work on the stops and the feed length as well as on the glue nozzles and the press fingers.

Machines can be connected in series to apply different forms. It is also possible to pro Train several appropriately controlled swivel arms 5 ^ with pliers 57, e.g. to enable the same or different items on the sets of a continuous form to be placed in different places To attach stickers. One or more stickers can also be omitted by programming according to e.g. a hundred forms will. It is also possible to carry out different steps simultaneously with one of the process steps, e.g. with gluing to connect continuous webs lying on top of one another, for example by means of a punching process. It is also possible not to glue the guide tape or the continuous form, but rather to bring the glue to the sticker.

An essential characteristic of the machine described above is that the sticker can be placed anywhere on a Web can be applied and attached to this, the stickers are specifically guided and held until their Connection with the train is ensured.
