The device has a fixed work table 11 and a movable work table 12, which in the direction of the

209820/0740

fixed work table 11 is movable to and away from him. A crank mechanism (not shown) in a known IOm for presses is provided to the worktable 12 in the direction to move towards the work table 11 and move away from it. The device has various operating stations, each of which derives its driving force from the movement of the work table 12 derive. At one end of the direction of the door there is an additional forming station 1J, which receives a continuous strip 14 made of fluoro iron, both sides of which are coated with an insulating varnish. Blanks produced by station 13 are conveyed to a corrugating station 15, and corrugated blanks are conveyed by station 15 to a upsetting station 16. The, traffic jam produces incomplete cores for ignition coils, which are then conveyed to a dimensioning station 17. The dimensioning station is used to complete the cores and feed them a transport slide 18, by means of which the finished cores leave the device.

The molding station receives the iron strip Η, which is gradually introduced from a roll of tape into the device, which is mounted at one end of the door direction. The mechanism Toa conveying the belt 14 into the device is driven by the lifting movement of the work table 12, and for iodine the complete lift of the work table 12, i.e. for a movement of the work table 12 from its fully raised position through its fully lowered position back to its fully raised position Position, a piece of tape, the length of which corresponds to the core to be produced, is inserted into the device. The blank forming station has a cutting tool with two knives 21, which are seated on the work table 12 and which work together with corresponding knives (not shown) on the fixed work table. The knives 21 are in one Distance from one another, which corresponds to the nominal width of a blank to be produced, and the length of the respective sea 21 is the same length? of the blanks to be produced.

B # r 21 thus act on the incoming strip 14 to ensure that the strip has the desired width and also to ensure that the lateral edges of the incoming strip have the desired orientation with respect to the downstream cutting of the cut-to-size fora station. When taking · that the work sequence starts with the work table 12 in its lowest position, a piece of tape 14 is guided in a fixed length between the movable eseer 21 and the fixed knives of the cutting tool when the work table 12 is raised. With the arrival of the work unit 12 in its highest position and bit of its lowering in the direction of the work table 11, a feeding of the belt 14 ceases and the fixed length Aee belt 14 becomes trimmed by the knife 21. The work table 12 then begins to move clay away from the work table 11, and one more piece of Volume 14 is introduced into the Beechneendungewerk «eug. With the Inserting further lengths of tape 14 into the trimming tool will gate the trimmed piece between the fixed and movable parts of a slotting tool 22 out. The slotting tool has a number of punches, which has a cross section are rectangular and which are slightly smaller in length than the length of the core to be produced. There is still a lot to be explained, If the core to be produced is cylindrical, the stamps of the sole seatwork do not all have the same width. Di · stamp take in their broad tone of the longitudinal center line of the Werksevg in Sighting of the lateral band "x det Verkseugs", with the widest stamp on the center line of the tool vanishing. ? »Rn« r ninat also the distance between the punches in a corresponding manner. The punches are seated on the movable work table 12 of the press, and the fixed work table carries a part with recesses which are in alignment with the punches. With the lowering of the movable work table in the direction of the fixed work table, the punches exert a shear effect on the belt, and each punch creates two longitudinally extending slots in the band Η.

As already mentioned, the pistons are slightly shorter in length

209820/0740 - 10 -

than the length of the portion of tape * going into the slotting tool has been introduced so that this part has an unslit area at both ends. Due to the dimensioning and the The distance between the punches of the cutting tool is reduced by the section between the slots produced in the belt in the direction of the lateral hands of the belt. The effect of the slotting tool is essentially shearing, so that the tape is formed with alternating regions between the slots which are pushed downward out of the plane of the side of the tape. It is understood that with the processing of a piece of tape through the Slitting tool the cutting tool processes a subsequent piece of tape. Hit the renewed wandering of the work table 12 of the fixed work table 11 is the belt 14 again inserted in the direction of the gate, and consequently there is a slit Piece of the band 14 out of the Schiitzerkzeug »and into a 'Finishing tool 23 introduced. The finishing tool has two flat plates, one on the movable work table and the other on the fixed work table. The width of the Plates are greater than the width of the belt and the length of the plates is substantially equal to the length of the core to be manufactured. When the work table 12 moves down again in the direction of the work table 11, the finishing presses tool the slotted tape flat to make the slotted tape substantially flat · S3 is understood that with the Flatten the slotted piece of tape, more pieces of tape can be slit and simultaneously slit through the upstream tools. Sin subsequent · startup of the Work table 12 again leads to the introduction of another Pieces of tape in the direction of the goal, so that the flattened or flattened piece of tape is guided to a pair of scissors.

The scissors 24 (Fig. 3) has a movable knife 25 which scratches on the work table 12, and a fixed knife 26 that sits on the work table 11. i) ae tape is moved over the edge of the stationary reader 26 ura an amount equal to the length

of the core to be produced, and the free end of the band 14 · the rom tool 26 is away, is supported by a bolt 27. The bolt 27 is pivotably mounted on an extension 28 of the fixed work table and is pressed by spring force into a position in which it supports the free end of the band 14 above the work table standing on the feet. The movable part of the bolt 27 is provided with a curved surface 2 $ on which a curved guide 31 can act on the movable work table 12. Hit the downward movement of the movable work table 12, the tool 25 separates the protruding piece of tape 14 from the best of the tape 14t and at the same time the cam guide 31 releases the bolt 27 opposite the tape Η, so that the severed piece of tape I4 opposite the Kesser 26 can be omitted. The cut piece of the band 14 forms a blank which is conveyed to the expansion station 15.

The blank 32 (Fig. 5) has a length equal to the length of the core to be made and has a number of longitudinally extending slots that make the blank 32 in number subdivided by lamellae 33, which aa respective 2nd duroh unprotected areas 34 are connected to one another. The width of the lamellae 33 is such that with a subsequent corrugation of the surface J2 along the lines of the slots and after compression, the resulting non-finished core is essentially cylindrical in shape. Λ

The blank 32 cut from the tape 14 falls on the fixed work table 12 facing the direction of the gate and is transported to the lungsstatlon 15 by a transport device. A jet of air ensures that the blank is not on CoherenmesBer gets stuck.

The carriage consists of two cylindrical rods 36, 37 which are guided for sliding movement in the longitudinal direction of the work table 11 opposite in bearings that sit on the work table 11. At the ends) the TCMB belt infeed is distant, are the rods 36, 37 Bit serrated areas 36a »37a which each lead through internal serrated» sleeves 38,39. The internally serrated sleeves are coupled to a coupling (not shown), by means of which the HtIl β en and thus the rods 36, 37 ic rotation can be offset by a certain angular path. The pods bind each with Coupled levers, which in turn act on respective air springs 41. The air springs 41 press the sleeves and thus the rods 36, 37 in such a direction that they tend to be in their to turn back the original angular positions. The rotating reciprocating movement of the rods 36, 37 is controlled by a Controlled cam mechanism that controls the rotating reciprocating movement of the rods according to the position of the working table 12 in a tentative relationship.

The ends 36a, 37a of the rods 36 »37 are through a bridge piece 42 connected to one another, in which the ends of the rods 36, 37 are rotatably mounted. The bridge cover 42 is connected via a cam-controlled coupling to the crank mechanism for driving the work table 12 in such a way that for a complete stroke of the work table 12, the carriage 35 has a full one Stroke in sighting along the fixed work table 11 executes. Kit for the execution of a single stroke of the movable work table 12, the carriage 33 thus leads a single stroke off, namely in the longitudinal direction of the gate direction, while the rods 36 »37 also perform a rotating reciprocating movement, the rods 36, 37 la opposite Vinkelrlchtungen being rotated.

The cam controlled coupling that the bridge piece 42 with the The crank mechanism of the press couples, has an air spring,

which opposes a movement of the coupling in one: direction for moving the carriage in the direction of the blank forming station. The slide is positively moved by a rotatable cam guide on the drive of the press - in this direction - so that the air spring is compressed as a result. However, the movement of the carriage in the gate pushing direction is brought about by restoring the initial state of the air spring, so that in the event of a blockage of the transport device, the air spring is prevented from moving apart through the bio-booking, so that the crank mechanism of the press continues to work without the transport device being activated a Riohtung is moved to promote components Duroh the door direction. In the Torrichtune an elec- tric like counting device is provided which Toll Permanent Hube transport one device. In the event that the transport device does not reach a full stroke, the counting system switches on a device for switching off the door direction. It goes without saying that in the event of a blockage of a part within the door direction and thereby a hindrance to the work of the transport device, the door direction switches off automatically in order to largely exclude the risk of damage to the door direction.

The transport device also has two arms 43 which sit under the blank 32 when the blank 52 is separated from the tape 14 will. The severed piece 32 falls on the arms 43, and with the departure of the work table 12 from the work table 11 to f When the blank is separated from the tape, there is a movement of the Carriage 35 in the longitudinal direction of the gate direction in Riohtung the band 14 closed. The arms 43 move with the carriage and thus slide under the severed blank 32. The arms 43 come to the area of the rear edge of the blank and allow the blank falling all the way onto the stationary work table with the arms at the rear of the blank. The arms 4'i are mounted on the rods 56, 37 in such a way that they move axially, but not at an angle, with the rods. before the movable work table 12 its end of movement away from

When the fixed work table 11 is reached, the sole center 35 is moved in one direction away from the blank form station under the action of said air spring, bo that the blank reaches the Vellungsstation. The movement of the sled 35 goes in the Vörechub direction during the beginning of the downward movement of the work table 12 to the end, so that the arms 43 have a position in which you are ready to take another blank, which has been cut from tape 14.

The Vellungsstation is arranged with three longitudinally spaced The stages are fitted out from conscientiousness considerations, the mode of operation of the three stages being essentially the same.

The first stage 45 of the expansion station (FIGS. 6, 7 and 8) has three tools which can be set in a sequence and which consist of punches and anvils. The first anvil 46 (FIG. 9) is attached to the work table 11 and forms a two longitudinally extending ribs 47 "48 triangular cross-section", the ribs 47, 48 forming a longitudinally extending V-shaped groove 49 between them. The aaboss 46 extends in the longitudinal direction of the device, and the length of the anvil is slightly greater than the length of the center 32, ie a length is slightly greater than the length of the core which is to be manufactured. On the opposite side of the anvil 46 are a second anvil 51 and a third anvil (not shown), the second and third anvils each forming a longitudinally extending rib of triangular cross-section and the length of the second and third anvils being the same is the length of the anvil 46. The second and third anvils are normally spaced outwardly from the first anvil, but they are movable, as will be described later, in order to come into abutment with the first anvil. In systems at harvest anvil of the second and third Anboß each form ^a V-shaped ITuten on opposite Ueiten the V-shaped hat 49.

fifth anvil (not shown). The fourth and fifth anvils are the same length as the first, second and third anvils, and the fourth and fifth anvils are also movable in the direction toward and away from the first anvil. The fifth and fourth anvils do not form triangular ribs, but rather have a flat top and an inclined surface facing the second and third anvils, respectively. When the fourth and fifth anvils attack the second and third anvils, respectively, the inclined surfaces of the fourth and fifth anvils together with the second and third anvils each form V-shaped grooves between the second and fourth anvils and between the third and the fifth anvil. Bi * first stage 45 further includes a punch dressing 55, similar sitting on movable work table 12 · Ser stamp dressing is provided in three sections, namely a first section 54 "EU de" a first punch 55 is one, a second portion of $ 6 to the a second stamp 57 and a third stamp (not shown), the second and third stamps sitting on opposite sides of the first stamp, and a third section 58, including a fourth stamp 59 and a fifth stamp (not shown) wherein the fourth and fifth punches sit on opposite sides of the association formed by the first, second and third punches.

The third section 58 is fixedly mounted on the work table 12 and forming a cylinder within which the second portion 56 eats sawn i wegbar, wherein the second portion iet 56 formed by a piston | Sealing rings sit in grooves on the outer surface of section 56 and bear against the inner surface of section 58. The section 56 also forms a cylinder within which the section 54 is movable. The section 54 also forms a piston and is provided with sealing rings. Compressed air is admitted into a chamber 61 via an inlet channel 62 in the section pG. The ends of the sections 54 and 5 ° form a wall of the chamber 61, and consequently the sections 5Ί and 56 are urged to move downwardly to the work table 12 and the section 58 opposite.

When the work table 12 is in a raised position, the first punch 55 is above the second and the third stamp downwards, and the second and third stamp in turn stand above the fourth and fifth Stamp out downwards. It goes without saying that the first punch moved together opposite the second and third punch can be, and also the first, the second and the third punch can be opposite to the fourth and the fifth punch move together, with the movement of the stamps in the direction of the work table 12 and against the spring action of the compressed air he follows.

After the middle area of the blank has been completely bent into the hat 49, the punch 55 is of course locked. At this stage, however, the work table 12 has not yet reached its lowest position, and consequently it moves further downwards in the direction of the work table 11.

The second and third anvils now begin moving toward the first anvil in the following manner. The second anvil is mounted on one end of two push rods 65, which ax their opposite ends carry curve scanners 66, on which curve guides 67, which are seated on the movable work table 12, engage. The rods 65 are mounted for sliding movement in an Akmboßbearing body 68 which is fixed to the work table 11, and the track guides 67 and the cam scanner 66 are arranged so that with the start of the bending of the blank on the side of the second and third punch, the second and the third anvil can be moved towards the first anvil. The arrangement is so provided that during this movement both the second and the third punch and the second and the third anvil exert a bending effect on the areas of the blank between the first and the second anvil or between the first and the third anvil . The cam guides 67 and the cam followers 66 are arranged in such a way that the second and third anvils engage the first anvil when the second and third punches have finished their vague movements. The blank is thus simultaneously bent along the lines of the second and third and the fourth and fifth slits. Upon bending, the areas of the blank on opposite sides of the area being bent are pulled inward. The third anvil is moved simultaneously and in the same way as the second anvil by a cam guide, by cam followers and by a push rod.

at this point in time the sixth and the seventh slot are in alignment with the vertices of the triangular hips of the second and third Abmoss ·. When the fourth and fifth punches start to lay the blank, the fourth and fifth anvils begin moving in the direction of the second and third anvils, respectively. The fourth anvil is also mounted on the end of two push rods 69, which are slidably mounted in the body 68, the opposite ends of the push rods being connected to a curve scanner 71 on which a cam guide 72 can be placed, which sits on the work table 12. Ss understood SiOH, that the third and the fifth anvil in the same Veice be moved, such as that described for the case of the second and fourth i anvil, and simultaneously therewith, the Torrichtung push rods, cam follower and cam guides facing said are assigned to the third and fifth anvil and are identical in form and function to the form and function that has been described in connection with the second and fourth anvil The blank is thus bent around the sixth and seventh and eighth and new slots at the same time, while I move the fourth and fifth anvils toward the second and third anvils, and the fourth and fifth punches toward the anvils. As already mentioned, the fourth and fifth anvils do not form triangular ribs, but rather have flat tops. Correspondingly, the fourth and the fifth punch have flat surfaces which sit opposite their respective triangular ribs on the outside. With the completion of the movement of the fourth and the fifth punch, the blank is also bent around the tenth and eleventh slot, the blank being bent around the tenth and eleventh slot into a position in which the outer, non-corrugated areas of the blank are coplanar are. The fourth and the fifth punch are locked when the work table 12 arrives in its lowest position. The work table then begins to move away from work table 12 in order to lift the Stonpelverbana irj5 away from the anvil verbana. Since the first, second and third stamps are printed by compressed air to the ante, as has been described,

rüokfahren the stamp association 53 Tom anvil association the fourth and fifth stamp from the blank "before the second and the third Do stamps, and accordingly the second and third stamps separated from the blank before the first stamp was separated. The cam guides 67 and 72 separate from theirs respective curve scanners 66, 71 in a corresponding manner, however a separation of the cam guides from the cam scanners does not result to a · retraction of the anvils. So although the stamps separate from the blank and into their starting positions relative to one another return, the anvils remain in an unconsolidated form at this stage. Sa the partially corrugated blank in one Engages with the anvils and is adapted to the grooves that are formed by the anvils, a moving apart of the anvils in their "open fora" would damage the lead the corrugated part of the blank.

The transport mechanism is equipped with two further transport arms 74 which are clamped to the rods 36 and 37, respectively. · The arms 74 move in the longitudinal direction in the same way as the arms 43 but also perform an angular movement with the rods 36 and 37 · The arms 74 sit in front of the blank 32 when the blank 32 first moves into the first stage of the corrugation set has been. With the arrival at the end of the movement of the work table 12 in the direction of the work table 11 for felling the blank the arms 74 begin to rise while the rods 36, 37 rotate. The arms, in a raised position, wander then looking at the blank forming station, and before the work table 12 reaches its lower end of movement, the arms are lowered in order to reach behind the partially corrugated fabric. The arms 74 are then moved in the opposite direction and transport the partially corrugated blank to the second stage of the corrugating station, while the arms 45 transport a second blank to the first stage. In an escape with the first anvil and through the entire processing station, through all three stages, a guide rail is provided,

whose surface corresponds to the shape of the first * anvil. Hit the Pushing a partially corrugated blank from the first stage to the second stage will result in the blank in the desired orientation the best of the door direction opposite through the guide rail held.

When a partially corrugated blank has been moved into engagement with the first stage anvils, the anvils can be returned to their original positions where they await another cycle of work. The second and fourth anvils return to their original positions by means of a pneumatically driven cylinder 75, the piston of which is coupled to a push rod 75a, which is mounted in a passage in the anvil support body 68 for sliding movement. At the end, which is remote from the cylinder 75, sits on the push rod 75a a lever 76 which can be brought into contact with the second anvil. When the cylinder is impacted, the piston is withdrawn, whereby the rod 73a and consequently the second and fourth anvils are drawn in the direction of the cylinder, in order to return the second and fourth anvils and the associated curve tracers to the starting positions where they are for the ready for the next work step. The third and fifth anvils are made equally whiteness by one. second cylinder 77 brought ^into their starting positions. The cylinders 75t 77 are operated simultaneously so that both the second and fourth and the third and fifth anvils are returned simultaneously. The operation of the cylinders 75, 77 is synchronized by a cam control mechanism which ensures that the anvils are not in their original positions are returned until the transport arms 74 have brought the blank out of engagement with the anvils. After the anvils have been withdrawn, the cam control mechanism 8 causes the cylinders 75, 77 to function in the opposite direction, around the finger 76 and the cylinder 77 assigned finger to the starting position.

The second stage 78 of the corrugation B3tation is practically identical with the above-described ground level. The anvil bandage

has a first anvil 81 facing the work table 11 is fixedly located and which forms two triangular ribs, one of which is shown at 82. The two triangular hips are in Spaced on opposite sides of the longitudinal center line of the corrugation station, and between the two ribs the first anvil is provided with two triangular ribs, which form extensions of the first anvil of the first stage and which the partially corrugated blanks in the correct position second Orientate level. On one side of the anvil there is a second and a fourth anvil 83, 84 which correspond to the second and fourth anvils of the first stage, although they are smaller in size. The second and fourth anvils 82, 84 are in Direction of the anvil 81 by means of push rods, curve scanners and cam guides movable in exactly the same way as has been described in connection with the first stage. on the opposite side of the anvil 61 sit a third and a fifth anvil, which are also movable in the manner as described in connection with the first stage. Two cylinders 85, 86 (Pig. 2) are simultaneously with the Cylinders 75 »77 can be actuated to return the anvils to their starting positions. The second stage stamp association 87 is similar to the first stage stamp association 53 and has a first Section 88 to which a first punch 89 and a second punch (not shown) include a second section 91 to the a third punch 92 and a fourth punch (not shown) belong, and a third section 93 which is fixedly connected to the movable work table 12 and to which a fifth Stamp 94 and a sixth stamp (not shown) belong. The first and second punches are spaced on opposite sides of the longitudinal centerline of the corrugation station and can be moved into the third and fourth punches against the spring force of compressed air, as has been described in connection with the first stage. The third and fourth stamps are arranged in the abatand on opposite sides of the first and second stamp and are the fifth and the sixth

Stamp opposite also against the spring force of compressed air movable.

When the partially corrugated blank is in the second stage, the central corrugations rest on the ribs of the first anvil, which form extensions of the first anvil in order to locate the blank in the correct position. In this position the tenth and dex eleventh slot of the blank must be where it As you can remember, it is about the last slots, the length of which was bent in the first step, in alignment with the vertices of the first anvil. The first and second punches of the second stage are arranged to grip the lamellae between the eighth and tenth slots and between the ninth and eleventh slots, respectively, to ensure that the tenth and eleventh slots have the vertices the ribs of the first anvil collapse. So the first and second punches do not necessarily perform any Bending effect on the blank, assuming that the blank does not move during its transport from the first stage stretched or contracted. However, Ss is desirable make sure that the tenth and eleventh slots actually coincide at the apex of the ribs of the first anvil, in order to have the effects of tolerance accumulation over the width of the Reduce cutting to a minimum.

The operation of the second stage of the Vellungsstation after the The cessation of movement of the first and second punches is identical to that described in connection with the first stage and after the cutting along the lines of the tenth, twelfth, fourteenth, sixteenth and eighteenth slots through the third and fifth punches and the second and fourth anvil and along the lines of the eleventh, thirteenth, fifteenth, seventeenth and nineteenth slots · has been bent by the fourth and sixth punches and the third and fifth anvils, the movable work table 12 travels again away from work table 11. Two more transport arms are attached

the rods 36, 37 are clamped, work simultaneously with the modes of transport 74 to remove the partially corrugated blank from the second Vellungsciaafe to move into the third corrugation stage while the arms 74 a blank previously corrugated in the first stage and the arms 43 a non-corrugated blank Transport the blank to the first stage.

The third stage 97 of the expansion station 15 is in its operation similar to that of the two previous stages, and it comprises an anvil dressing with a first anvil which is attached to the worktable 11 opposite is arranged stationary and a first triangular ™ rib 98 and a second triangular rib (not shown). The two ribs of the first anvil are spaced on opposite one another Sides of the longitudinal center line of the elliptical station arranged, and the first anvil also forms two centrally located triangular ribs, the guide rail elongated grooves of the triangular ribs dea reaping form alibosses of the first stage. A second and a fourth ambo £ sit on one side of the er.iten Anvils on the rib 98 and are directed towards the rib 98 of the The first anvil is movable towards and away from it in a manner and manner identical to that used in connection with the first Level of V / ellungsatation has been described. 3citzen accordingly a third and a fifth anvil on the second triangular rib of the first anvil and are placed opposite the first anvil in moves in a manner identical to that which is related has been described with the first stage. As the third stage to act on areas of the blank on the lateral Edges of the lining are provided where the slits in the closely spaced, the dimensions of the anvils of the third stage are smaller than those of the anvils of the two upstream Stages. The stamp association 102 of the third stage corresponds in its structure to the stamp associations of the two upstream ones Steps and has three mutually movable sections, one of which is fixedly arranged opposite the movable work table 12 and the other two can be moved against each other;

209820/0740

In addition, they can be moved across from the third section, in each case against the action of compressed air. The first section 10J has a first sterile stack 104 and a second stamp (not shown), these two stamps being arranged at a distance on opposite sides of the longitudinal line of the station. The second section 105 has a third punch 106 and a fourth punch (not shown), and a fifth punch 108 and a sixth punch (not shown) correspondingly belong to the fixed section 017. The first and the wide section are urged to move relative to each other and the third section, in a direction towards the anvil bandage, the application being effected by compressed air. The 3 stamp association 102 functions in the same way as has been described in connection with the first and second stages of the corrugating station. The stamps of the association 102 are structurally similar to the stamps of the upstream stages, namely in that they each form a longitudinally extending rib which has a triangular cross-section and the length of which is approximately greater than the length of the blank. The dimensions of the punches and anvils of the third stage are smaller than the dimensions of the punches and the anvils of the preceding stages, since the distance between the slots of the blank along which the blank is to be bent in the third stage is smaller than that Is the distance between the slots that are closer to the center of the blank. The third and fourth punches are each provided with an outwardly extending protrusion, one of which is shown at 105. The projections 109 sit approximately in the middle in the longitudinal direction of the associated punch and are used when the third and fourth punch are actuated to bend the blank along the lines of the twenty-first and twenty-third slot. This bending the cutting length of the lines of the. twenty-second bsv :. the twenty-third slot ensures that the fifth and sixth punches

Bs it goes without saying that in view of the small dimensions of the Fins toward the edges of the blank after bending the blank through the twentieth and twenty-first slots the remaining parts of the blank, di · the twentieth and the The twenty-first Shiita lie opposite to the outside, essentially upwards towards the punches Torstenen, instead of sideways at right angles to the direction of movement of the punches. The games 109 of the third and fourth punches ensure that the desired area of the remainder of the blank from the fifth and sixth stamp can be seized. The Yorsjunge 109 have a · short length, and the fifth and sixth punches are provided with slots into which the gate projections 109 engage when the second section 105 enters third section 107. Of the fifth and sixth punches together with the second, third, fourth and fifth anvil bend the blank along the lines dec the twenty-second, twenty-third, twenty-fourth, and twenty-fifth Slot to complete the corrugation of the blank.

When the work table 12 is raised again after the blank has been completely corrugated, two further transport arms 111, which are also clamped to the rods J6, 37, transport the finished corrugated blank to the dipping station 16. It goes without saying that with the transport of the finished corrugated blank to the upsetting station the tape 14 is introduced into the blank formation, a first piece of the tape is brought into a position for trimming, a further already trimmed piece of the tape is brought into a position in which the slitting takes place, a slotted piece of the tape in a layer is flattened, a flattened / flattened piece is brought into a layer to be severed, a severed blank is transported to the first stage of the corrugation, a partially every blank is transported to the second stage of the corrugation station
