Description

Die Erfindung betrifft eine Vorrichtung zum Verbinden eines Drahtes mit einem Kontaktelement od.dgl. durch Verformen von Klemmteilen des Kontaktelementes od.dgl. mittels Druckorganen, insbesondere Druckorgan eines auswechselbar in einer Anschlagpresse angeordneten Crimpwerkzeuges mit bewegbarem Crimpstempel, der in einer Crimpstellung die Verformung durchführt. Zudem erfaßt die Erfindung ein Verbindungsverfahren für Kontaktelemente.The invention relates to a device for connecting a wire to a contact element or the like. by deforming clamping parts of the contact element or the like. by means of pressure elements, in particular the pressure element of a crimping tool which can be exchangeably arranged in a stop press and has a movable crimping die and which carries out the deformation in a crimping position. The invention also covers a connection method for contact elements.

Vorrichtungen dieser Art für die Kabelkonfektionierung --beispielsweise für das feste Verbinden von Drahtenden mit Steckern und Kabelschuhen -bestehen üblicherweise aus einer Anschlagpresse mit vertikal bewegtem Pressenstempel, der auf einen Druckkopf des darunter angeordneten Crimpwerkzeuges einwirkt, wobei in diesem vorgesehene Crimpstempel nach unten geführt werden und ein horizontal eingeschobenes Steckerorgan od.dgl. Kontaktelement unter Verformen von Klemmfahnen an einem Kabel- oder Drahtende festlegen. Letzteres ist auf eine gewisse Länge abisoliert, so daß ein zum isolierten Abschnitt geringerer Durchmesser entsteht. Die zu dem beschriebenen Crimpvorgang notwendige sogenannte Crimphöhe der einwirkenden Stempelkante/n wird in Abhängigkeit von den Drahtquerschnitten bzw. der Form des Kontaktelementes von Hand eingestellt.Devices of this type for cable assembly - for example for the firm connection of wire ends with plugs and cable lugs - usually consist of a stop press with a vertically moved press stamp, which acts on a print head of the crimping tool arranged underneath, the crimping stamps provided being guided downwards therein and a horizontally inserted plug member or the like. Fix the contact element by deforming the terminal lugs at one end of the cable or wire. The latter is stripped to a certain length, so that a smaller diameter than the isolated section is produced. The so-called crimp height of the acting stamp edge (s) required for the crimping process described is set manually as a function of the wire cross-sections or the shape of the contact element.

Eine Vorrichtung der eingangs genannten Art mit einem Formstempel oder Crimper, mittels dessen Blechfahnen durch Verformen an ein Kabel angeschlossen werden, beschreibt die DE-OS 40 39 051 der Anmelderin. Die Kanten der querschnittlich U-förmigen Blechfahne werden durch den Crimper eingerollt, so daß ein -- ebenfalls querschnittlich -- etwa herzförmiges Gebilde entsteht.DE-OS 40 39 051 of the applicant describes a device of the type mentioned at the beginning with a form stamp or crimper, by means of which sheet metal flags are connected to a cable by deformation. The edges of the cross-sectionally U-shaped sheet metal flag are rolled up by the crimper, so that a - also cross-sectionally - approximately heart-shaped structure is formed.

Oftmals ist es erforderlich, in hülsenförmige Kontakte mehrere radiale Einformungen einzubringen, wozu beispielsweise sternartige Räder an einem Hebelarm bekannt sind, die mit mehreren Anschlagflächen um eine Achse drehen. Solche Geräte sind mit eigenem Antrieb versehen und insgesamt individuell gestaltet, d.h. kontaktspezifisch -- und damit aufwendig --konzipiert.It is often necessary to introduce a plurality of radial indentations into sleeve-shaped contacts, for which purpose, for example, star-like wheels on a lever arm are known which rotate about an axis with a plurality of stop surfaces. Such devices have their own drive and are individually designed overall, i.e. contact-specific - and therefore complex - designed.

In Kenntnis dieses Standes der Technik hat sich der Erfinder das Ziel gesetzt, eine Vorrichtung der eingangs genannten Art zum Herstellen mehrerer Einformungen in ein hülsenförmiges Kontaktelement sowie als Schnellwechselwerkzeug für Anschlagpressen zu gestalten. Letztere können dann als flexibles Basisgerät eingesetzt werden.Knowing this state of the art, the inventor has set himself the goal of designing a device of the type mentioned at the outset for producing a plurality of indentations in a sleeve-shaped contact element and as a quick-change tool for stop presses. The latter can then be used as a flexible basic device.

Zur Lösung dieser Aufgabe führt die Lehre der unabhängigen Ansprüche; die Unteransprüche geben günstige Weiterentwicklungen an.The teaching of the independent claims leads to the solution of this problem; the subclaims indicate favorable developments.

Zum Erzeugen mehrerer Verformungsbereiche am Kontaktelement ist eine deren Anzahl entsprechende Zahl von Crimpstempeln um eine Aufnahmeöffnung angeordnet, die durch Druckbacken od.dgl. Organe in die Crimpstellung überführbar sind, wobei die Druckbacken od.dgl. Organe ihrerseits durch zu ihnen in einem Winkel bewegbare Druckstempel bewegbar sind.In order to produce a plurality of deformation areas on the contact element, a number of crimping dies corresponding to their number is arranged around a receiving opening or the like by means of pressure jaws. Organs can be transferred to the crimp position, the pressure jaws or the like. Organs, in turn, can be moved by pressure stamps movable at an angle to them.

Dazu hat es sich als günstig erwiesen, beidseits einer Symmetriegeraden zu ihr etwa parallele Druckstempel des Crimpwerkzeugs anzuordnen, die mit in einem Winkel zur Symmetrieachse geneigten Flächen in die Bewegungsbahn von Schrägflächen der Druckbacken eingreifen.For this purpose, it has proven to be advantageous to arrange pressure stamps of the crimping tool that are approximately parallel to it on both sides of a line of symmetry and engage with surfaces inclined at an angle to the axis of symmetry in the movement path of inclined surfaces of the pressure jaws.

Zum Rückführen des Druckbackens liegt erfindungsgemäß dessen Schrägfläche/n jeweils eine parallele Schrägfläche gegenüber, die einer zweiten geneigten Fläche jenes Druckstempels zugeordnet ist. Die zusammenwirkenden Rückholflächen der Druckbacken und Druckstempel verlaufen zur Wiederherstellung der Ausgangsstellung zur Symmetrieachse geneigt.To return the pressure jaw, according to the invention, its inclined surface (s) is opposite a parallel inclined surface, which is assigned to a second inclined surface of that pressure stamp. The interacting return surfaces of the pressure jaws and pressure stamps are inclined to restore the initial position to the axis of symmetry.

Nach einem weiteren Merkmal der Erfindung weist der Druckbacken eine Keilfläche auf, welche die Achse des zugeordneten Crimpstempels quert und auf eine zu ihr parallele Stempelfläche drückbar ist. Der Crimpstempel selbst wird erfindungsgemäß durch einen Kraftspeicher, insbesondere eine Druckfeder, aus der Crimpstellung zurückgeführt.According to a further feature of the invention, the pressure jaw has a wedge surface which crosses the axis of the associated crimping die and can be pressed onto a die surface parallel to it. According to the invention, the crimping die itself is returned from the crimping position by an energy store, in particular a compression spring.

Als günstig hat sich auch erwiesen, die Achse des Crimpstempels etwa rechtwinkelig zur Keilfläche zu stellen und/oder den Crimpstempel gegen die Kraft eines Kraftspeichers in die Crimpstellung überführbar anzuordnen.It has also proven to be advantageous to set the axis of the crimping die approximately at right angles to the wedge surface and / or to arrange the crimping die in the crimping position against the force of an energy store.

Vorteilhafterweise kann in einen quaderförmigen Werkstoffblock sowohl die Keilfläche als auch eine gegenläufig geneigte Schrägnut eingeformt werden, wobei letztere die Schrägflächen für die Crimp- und die Rückholbewegung anbietet.Advantageously, both the wedge surface and an oppositely inclined inclined groove can be molded into a cuboid material block, the latter offering the inclined surfaces for the crimping and the return movement.

Nach einem anderen Merkmal der Erfindung greift in die Schrägnut des Druckbackens eine leistenartig vom Druckstempel abragende Rippe ein, welche jene geneigten Flächen aufweist. Auch diese -- mit einem heb- und senkbaren Drehkopf verbundenen -- Druckstempel sind auf einfache Weise aus einem Werkstoffblock spanabhebend zu erzeugen.According to another feature of the invention, a rib which projects like a strip from the pressure stamp and has those inclined surfaces engages in the oblique groove of the pressure jaw. These pressure stamps, which are connected to a rotating head that can be raised and lowered, can also be easily machined from a block of material.

Die Führung des Druckbackens zum Crimpstempel hin erfolgt gegen die Kraft eines Kraftspeichers, der -- bevorzugt als Schraubenfeder -- einen mit dem Druckbacken verbundenen und eine festliegende Führung durchsetzenden Sicherungsbolzen umfängt.The pressure jaw is guided towards the crimping die against the force of an energy accumulator which, preferably as a helical spring, surrounds a securing bolt connected to the pressure jaw and passing through a fixed guide.

Die erwähnte Führung für den Sicherungsbolzen ist eine Bohrung in einem Teil eines Gehäuses, in dem Gleitbahnen für die Druckbacken verlaufen. Quer zu diesen Gleitbahnen sind Schubbahnen für die Druckstempel gerichtet.The guide for the securing bolt mentioned is a bore in a part of a housing in which slideways for the pressure jaws run. Push tracks for the pressure stamps are directed transversely to these slideways.

Im Rahmen der Erfindung liegt es, daß zwischen den Schubbahnen ein austauschbarer Crimpeinsatz angeordnet und dieser mit Führungen für die Crimpstempel versehen ist. Diese Führungen sind radial zur Aufnahmeöffnung im Crimpeinsatz vorgesehen.It is within the scope of the invention that an exchangeable crimp insert is arranged between the push tracks and this is provided with guides for the crimping dies. This tour are provided radially to the opening in the crimping insert.

Mittels eines derart ausgestatteten Werkzeugs wird erfindungsemäß die Kraft der Anschlagpresse auf die Druckstempel des Crimpwerkzeuges aufgeteilt und jede Teilkraft des Druckstempels in zumindest eine dazu in einem Winkel stehende Kraft umgesetzt; mit letzterer wird der Crimpstempel beaufschlagt.By means of a tool equipped in this way, according to the invention, the force of the stop press is divided between the pressure stamps of the crimping tool and each partial force of the pressure stamp is converted into at least one force at an angle to it. the latter is applied to the crimp stamp.

Diese Einheit 10/20 dient zum Verbinden eines isolierten elektrischen Drahtes mit einem von einem Rohlingsstrang oder Blechstreifen 24 abgetrennten hülsenförmigen Kontaktelement 26. Dieses wird auf das zuvor abisolierte Ende jenes Drahtes und den anschließenden Abschnitt der Isolierung unter Verformung aufgedrückt bzw. gecrimpt; beim Crimpen verformt sich die Hülse 26 so, daß z.B. die Litze des Drahtendes fließt und Lufteinschlüsse unterbunden sind.A stop press 10 for processing wires or cables has a quick-change crimping tool 20 beneath a press housing 14 with adjusting disk 16 and press ram 18 - with control and pressure devices and provided on frame legs 12 - with a working stroke of 40 mm Rotary head 20, which is acted upon by that press ram 18. This unit 10/20 is used to connect an insulated electrical wire to a sleeve-shaped contact element 26 which is separated from a blank strand or sheet-metal strip 24. This is pressed or crimped onto the previously stripped end of that wire and the subsequent section of the insulation with deformation; during crimping, the sleeve 26 deforms such that e.g. the strand of the wire end flows and air pockets are prevented.

Die Achsen Q dieser Crimpstempel 28 fallen also in jene Querschnittsgeraden Q1, Q, Q2.3 takes place in four areas A, which are determined by two cross-section lines Q1, Q2 which are approximately at right angles to one another. In these cross-section lines Q1, Q2, which intersect the tool center axis M in the tool center point Z, four crimping dies 28 run in guides 29 of a crimping insert 30 in the crimping tool 20. The axes Q of these crimping dies 28 thus fall in those cross-sectional lines Q1, Q, Q2.

Wie Fig. 4 verdeutlicht, sitzt der Crimpeinsatz 30 austauschbar in einem Gehäuse 32, das mit einer Bodenplatte 34, mit einer Frontplatte 35 der Dicke 1 von 10 mm, mit Seitenplatten 36 sowie mit einem Gehäusekörper 37 ausgestattet ist; dessen Tiefe a mißt hier 35 mm, der Durchmesser d einer zentrischen Bohrung 33 etwa 18 mm. Durch einen ebenfalls zentrischen, sich einwärts verjüngenden Durchbruch 31 der Frontplatte 35 ist der Crimpbereich B des Crimpeinsatzes 30 zu sehen.As illustrated in FIG. 4, the crimp insert 30 is exchangeably seated in a housing 32 which is equipped with a base plate 34, with a front plate 35 with a thickness 1 of 10 mm, with side plates 36 and with a housing body 37; the depth a here measures 35 mm, the diameter d of a central bore 33 is approximately 18 mm. The crimp area B of the crimp insert 30 can be seen through a likewise central, inwardly tapering opening 31 in the front plate 35.

In vertikale Schubbahnen 38 des Gehäusekörpers 37 greifen von oben her zwei Druckstempel 40,40a ein, die mit ihrer Stempelkopffläche 39 an eine Querplatte 43 des Drehkopfes 22 angeschraubt sind. Die Querplatte 43 steht in oberer Totpunktlage der Anschlagpresse 10 in einem Abstand h zum Gehäuse 32 (Fig. 4, 7). Befindet sich die Anschlagpresse 10 in ihrem unteren Totpunkt, verläuft die Querplatte 43 gemäß Fig. 6, 8 nahe dem Gehäusekörper 37.From above, two pressure stamps 40, 40a engage in vertical push tracks 38 of the housing body 37, which are screwed with their stamp head surface 39 onto a cross plate 43 of the rotary head 22. The cross plate 43 is in the top dead center position of the stop press 10 at a distance h from the housing 32 (FIGS. 4, 7). If the stop press 10 is at its bottom dead center, the cross plate 43 according to FIGS. 6, 8 runs close to the housing body 37.

Quer zur Werkzeugmittelachse M sind im Gehäuse 32 horizontale Gleitbahnen 44 für obere Druckbacken 46 und untere Druckbacken 47 zu erkennen, die in die Achsen von Sicherungsbolzen 48 fallen. Letztere durchsetzen jeweils eine Bohrung 36a in einer Seitenplatte 36 und sind von einer sich gegen diese und den Bolzenkopf 48a abstützenden Feder 49 umfangen.Horizontal slideways 44 for upper pressure jaws 46 and lower pressure jaws 47 can be seen in the housing 32 transversely to the tool center axis M and fall into the axes of securing bolts 48. The latter each pass through a bore 36a in a side plate 36 and are surrounded by a spring 49 which is supported against the latter and against the bolt head 48a.

Unterschiedliche Stellungen der mit ihrem Schaft an den Druckbacken 46, 47 festliegenden Sicherungsbolzen 48 sind jeweils rechts oben in den Fig. 7, 8 angedeutet. Wäre der Druckbacken 46, 47 nicht durch Sicherungsbolzen 48 und Feder 49 gesichert, so könnte er sich in seiner Grundstellung in der Horizontalachse verschieben und so beim Arbeitshub das Werkzeug beschädigen; die Feder 49 hält den Druckbacken 46, 47 in Position.Different positions of those fixed with their shank to the pressure jaws 46, 47 Locking bolts 48 are indicated at the top right in FIGS. 7, 8. If the pressure jaws 46, 47 were not secured by locking bolts 48 and spring 49, it could shift in its basic position in the horizontal axis and thus damage the tool during the working stroke; the spring 49 holds the pressure jaws 46, 47 in position.

Die Bewegungen der Werkzeugteile während des Umformens bzw. deren Kräfte sind durch Pfeile in Fig. 6 mit folgenden Bedeutungen kenntlich gemacht:

  • F1 = vertikaler Pressenhub;
  • F2 = Ãœbernahme von F1 als Längshub auf die Druckstempel 40,40a des Crimpwerkzeuges 20;
  • F3 = Ãœbernahme des Längshubes F2 für den Querhub der Druckbacken 46,47;
  • F4 = Ãœbernahme des Querhubes F3 als Diagonalhub für die Crimpstempel 28.
The movements of the tool parts during the forming or their forces are indicated by arrows in FIG. 6 with the following meanings:
  • F 1 = vertical press stroke;
  • F 2 = takeover of F 1 as a longitudinal stroke on the pressure stamps 40, 40a of the crimping tool 20;
  • F 3 = takeover of the longitudinal stroke F 2 for the transverse stroke of the pressure jaws 46, 47;
  • F 4 = acceptance of the transverse stroke F 3 as a diagonal stroke for the crimping dies 28.

Zur Durchführung dieser Hubabfolge wird ein -weiter unten beschriebenes -- Keilsystem eingesetzt.A wedge system - described further below - is used to carry out this stroke sequence.

Der von der Anschlagpresse 10 auf den Drehkopf 22 übergeleitete Pressenhub ermöglicht eine individuelle Werkzeugeinstellung; die Kraft F1 wird über die Querplatte 42 auf den linken und den rechten Druckstempel 40,40a -- jeweils einer Breite b von 19 mm, jedoch unterschiedlicher Längen n, n1 von 94 mm des linken Druckstempels 40 bzw. 100 mm des rechten Druckstempels 40a -- verteilt. Auf diese beiden wird der Hub von 40 mm der Anschlagpresse 10 direkt übergeleitet, so daß auch diese einen Hub dieser Größenordnung auszuführen vermögen.The press stroke transferred from the stop press 10 to the rotary head 22 enables individual tool setting; the force F1 is applied via the cross plate 42 to the left and right pressure stamps 40, 40a - each with a width b of 19 mm, but different lengths n, n1 of 94 mm of the left pressure stamp 40 and 100 mm of the right pressure stamp 40a - - distributed. The stroke of 40 mm of the stop press 10 is transferred directly to these two, so that they can also execute a stroke of this magnitude.

Die Druckstempel 40, 40a sind jeweils mit zwei Druckschrägen 50 ausgestattet, die in einem Winkel w von etwa 15 ° als Seitenflächen von Rippen 52 angeboten werden und um ein Maß e von hier 3 mm über eine erste Frontfläche 41 des Druckstempels 40 hinauskragen, dessen Tiefe b1 etwa 15 mm mißt. Zum Crimpeinsatz 30 hin wird zwischen der ersten oder äußeren Frontfläche 41 und einer zweiten -- inneren -- Frontfläche 42 ein quer verlaufender Schulterabsatz 42s gebildet. Die zueinander weisenden Stirnflächen der Rippen 52 sind mit 53 bezeichnet, und die obere Rippe 52 ist in Frontansicht wie eine "7" gestaltet; die Stirn des an der Stempelkopffläche 39 verlaufenden Querbalkens der oberen Rippe 52 ist bei 54 zu erkennen. Die Basisfläche 55 der eine Gerade bildenden unteren Rippe 50 steht in Abstand z zur unteren Stempelfläche 39t; dieser ist beim linken Druckstempel 40 kürzer als beim anderen.The pressure stamps 40, 40a are each equipped with two pressure bevels 50, which are offered at an angle w of approximately 15 ° as side surfaces of ribs 52 and protrude by a dimension e of here 3 mm beyond a first front surface 41 of the pressure stamp 40, the depth of which b1 measures about 15 mm. Towards the crimp insert 30, a transverse shoulder shoulder 42s is formed between the first or outer front surface 41 and a second - inner - front surface 42. The mutually facing end faces of the ribs 52 are designated by 53, and the upper rib 52 is designed in the front view like a "7"; the forehead of the crossbar of the upper rib 52 running on the stamp head surface 39 can be seen at 54. The base surface 55 of the lower rib 50 forming a straight line is at a distance z from the lower stamp surface 39t; this is shorter with the left stamp 40 than with the other.

Fährt der Druckstempel 40 -- gleichermaßen der andere Druckstempel 40a -- auf der anderen Seite der Symmetrieachse M abwärts, wirken die vertikal bewegten Druckschrägen 50 sowie die jeweils auf der anderen Rippenseite vorgesehenen parallelen Rückenschrägen 56 der Rippen 52 exakt mit entsprechenden Schrägflächen 58 -- bzw. Rükkenflächen 60 -- der horizontal geführten Druckbakken 46,47 zusammen. Dabei löst die vertikale Kraft F2 die horizontale Kraft F3 aus - die Längsbewegung geht über in eine Querbewegung.If the pressure stamp 40 - likewise the other pressure stamp 40a - moves downwards on the other side of the axis of symmetry M, the vertically moved pressure bevels 50 and the parallel back bevels 56 of the ribs 52 provided on the other rib side act exactly with corresponding inclined surfaces 58 - or respectively Back surfaces 60 - the horizontally guided pressure jaws 46, 47 together. The vertical force F2 triggers the horizontal force F3 - the longitudinal movement changes into a transverse movement.

Druckstempel 40,40a und Druckbacken 46,47 haben einen Zwangsrückzug, so daß beim Zurückführen der Anschlagpresse 10 die in den Gleitbahnen 44 geführten Druckbacken 46, 47 wieder in Grundstellung nach Fig. 7 gezogen sind.Plungers 40, 40a and pressure jaws 46, 47 have a forced retraction, so that when the stop press 10 is returned, the pressure jaws 46, 47 guided in the slideways 44 are pulled back into the basic position according to FIG. 7.

Wie vor allem Fig. 15 verdeutlicht, ist in den aus einem Werkstückquader hergestellten -- hier: unteren rechten --Druckbacken 47 ein seitlicher Ausschnitt 62 der Tiefe f von hier 7 mm eingebracht, von dessen Innenfläche eine Schrägnut 64 der Weite g von 5 mm im Neigungswinkel t in Duckrichtung x von etwa 75 ausgeht, deren Seitenwände sind jene Schrägfläche 58 und die Rükkenfläche 60. Diese Fig. 15 zeigt auch in der Quaderendfläche 61 eine Bohrung 61 a zur Aufnahme des erwähnten Sicherungsbolzens 48.As is particularly clear from FIG. 15, a lateral cutout 62 of depth f of here 7 mm is made in the pressure jaws 47 - here: lower right - pressure jaws 47, from the inner surface of which an oblique groove 64 of width g of 5 mm at an angle of inclination t in the pressure direction x of approximately 75, the side walls of which are the inclined surface 58 and the back surface 60. This FIG. 15 also shows a bore 61 a in the cuboid end surface 61 for receiving the securing bolt 48 mentioned.

Nahe der Schrägfläche 58 setzt an der anderen Seitenwand des Druckbackens 47 eine gegenläufige aufwärts gerichtete Keilfläche 66 des Winkels i von 45 ° an.Near the inclined surface 58, an opposing upward wedge surface 66 of the angle i of 45 ° is applied to the other side wall of the pressure jaw 47.

In der Ausführung der Fig. 18, 19 des oben linken Druckbackens 46 sind die Flächen 58, 60, 66 in gleichem Maße geneigt, jedoch weist hier die Keilfläche 66 abwärts.18, 19 of the top left pressure jaw 46, the surfaces 58, 60, 66 are inclined to the same extent, but here the wedge surface 66 points downwards.

Das Maß des bei Betätigung der Druckbacken 46, 47 erzeugten Querhubes F3 ist mit k bezeichnet. Der besseren Übersicht halber ist in Fig. 7, 8 der untere linke Druckbacken 47 schraffiert hervorgehoben.The dimension of the transverse stroke F 3 generated when the pressure jaws 46, 47 are actuated is denoted by k. For the sake of a better overview, the lower left pressure jaw 47 is hatched in FIGS. 7, 8.

In diesem Crimpwerkzeug 20 sind nun verschiedene Crimpeinsätze 30 mit den in Fig. 6 skizzierten Crimpstempel 28 anbringbar; diese werden beim Querhub x der Druckbacken 46, 47 durch die Keilfläche 66 zum Zentrum Z hin gedrückt; F3 wird in F4 umgesetzt.In this crimping tool 20, various crimping inserts 30 can now be attached with the crimping dies 28 outlined in FIG. 6; these are pressed by the wedge surface 66 towards the center Z during the transverse stroke x of the pressure jaws 46, 47; F 3 is converted into F 4 .

Das Rückholen der Crimpstempel 28 erfolgt durch nicht gezeigte Federn, sobald die Keilflächen 66 die Stirnfläche 29 der Crimpstempel 28 freigegeben haben. Beim "Auseinanderlaufen" der Crimpstempel 28 erweitert sich die von ihren Spitzen 27 begrenzte Zuführöffnung.The crimping dies 28 are retrieved by springs, not shown, as soon as the wedge surfaces 66 have released the end face 29 of the crimping dies 28. When the crimping dies 28 "run apart", the feed opening delimited by their tips 27 widens.
