Definitions
- the invention relates to a flat can for receiving sliver, which is delivered by cards or draw frames.
- the flat can serves as a container for receiving the delivered sliver and its transport to a further processing machine of the spinning mill, through which the sliver is removed from the flat can again.
- flat cans have the advantage that they can be set up and transported more cheaply.
- the flat can can store more sliver than a corresponding round can.
- filling and emptying the flat can is problematic compared to the round can, because the quality of the sliver must not be impaired in any way.
- Known flat cans consist of 2 elongated, parallel side walls and 2 end walls. All walls are arranged perpendicular to the can bottom (EP 344 484).
- the cross section of the flat can can be a rectangular shape, a rectangular shape with rounded corners (EP 344 484), a rectangular shape with rounded end pieces (DE-OS 40 15 938, Fig. 3A), or an oval shape.
- the can plate which is known to be movable, also takes on the corresponding shape and is lowered or raised according to the filling status of the flat can. As EP 344484 shows, it was customary for flat cans that the can plate is positioned at the level of the can rim when empty. The positioning is achieved by springs.
- the pantograph is intended to ensure that the can plate always remains horizontal during its lifting or lowering movement. At high traversing speeds, the can plate still tilts.
- the flat can When filling with sliver, the flat can is usually moved back and forth under the filling device in the longitudinal direction of the can, so that the sliver is deposited cycloid-shaped on the can plate in the direction from one end wall of the flat can to the other end wall by this traversing movement.
- several stored layers of sliver form a band column which, by means of its own weight, slowly lowers the can plate up to the stop on the bottom of the can.
- the can plate has an edge that is angled downwards towards the base (can bottom) and lies with its angled surface except for a small gap on the can walls.
- the can plate is carried at both ends by a spiral spring, which position the can plate in the unloaded state at the upper edge of the can.
- the sliver column which consists of a large number of layers of sliver lying on top of each other, their mass increases. Especially when the flat can hits the reversal point of the traversing, the effect occurs that the Sliver column fluctuates due to its inertia in the direction of the respective end face. The entire sliver column fluctuates. This swaying is annoying because it affects the sliver storage that is still running.
- pantographs which are symmetrically opposite each other on the longitudinal edges of the can plate, cannot prevent the can plate from tending to tilt in the direction of its longitudinal axis at increased traversing speeds. There is a risk of tilting against the wall. With the tilting of the can plate there is also the disadvantage that the single, suddenly loaded spiral spring bends out of its vertical axis.
- the object of the invention is to achieve proper tape storage when filling an oscillating flat can, which also enables error-free tape removal, and at economical storage speeds, as are possible with round cans.
- the feature of the flat can is that only one pantograph is arranged between the two spiral springs which are arranged in the region of the end walls.
- This single pantograph is arranged in the middle of the jug bottom and at the crossing points this pantograph are arranged horizontally struts, which are rotatably mounted in the respective crossing point.
- the ends of the struts are articulated to the opposite spiral spring. It is thus avoided in any position of the can plate and at high traversing speeds that the spiral spring bends out of its vertical position, as can be caused by fluctuations in the sliver column.
- the sliver is delivered from the drafting device to the turntable 2.
- the delivery direction A of the sliver is determined by the arrow.
- the turntable 2 with its mouth of the tape guide channel 1 rotates stationary and is surrounded by a machine table 3.
- the sliver leaves the mouth in the turntable 2 and is placed in the flat can 4 in a cycloid form.
- the storage of the sliver is not shown.
- Each individual layer of sliver is laid down over the entire width and length of the can plate.
- the can plate is movably arranged on the can wall. With an increasing number of sliver layers, the can plate must be able to lower towards the can base.
- the movement of the can plate can be carried out, for example, by an externally controlled lifting mechanism which is arranged under the can plate.
- the lifting mechanism is in engagement with the can plate.
- springs are arranged below the can plate, which move depending on the load on the can plate from an initial position (empty flat can) to a lowered position.
- a filled flat can is transported to a spinning machine for further processing of the belt.
- the width of a flat can therefore corresponds to the working width of a single spinning station.
- the flat can 4 can have a rectangular or oval base. The rectangular base with rounded corners is preferred.
- the flat can 4 is moved back and forth in the longitudinal direction (corresponding to double arrow B) underneath the turntable 2 of a draw frame or card, so that the can plate (not shown in FIG. 1) is covered with sliver over its entire length.
- the roller conveyor 6 consists of a large number of freely movable rollers which are arranged next to one another and at least correspond to the traversing path.
- the flat can 4 is oscillated on this roller conveyor 6.
- the flat can in the upper third (below the upper can bead 5) is gripped on both sides by a traversing bracket 8 and 80, these traversing brackets being connected to a chassis 9.
- This chassis 9 has a drive, not shown here. The drive is controlled according to a program for filling the flat can 4.
- the chassis 9 is guided along the rail 10.
- FIG. 2 documents the can structure known up to now according to EP 344 484, as can be seen within the can wall 13 and below the can plate 14.
- the flat jug is moved back and forth, ie it changes.
- the traversing speed is decelerated to the value zero at the reversal point, in order then to accelerate to the traversing speed immediately after passing through the reversing point.
- the analogous braking and acceleration process takes place.
- known flat cans after the formation of the first sliver layers for the end sling are displaced beyond the edge of the can (see FIG. 2). This is very unfavorable, especially in the high-speed area of traversing.
- the can plate is lowered over its entire length relative to the edge of the can (upper can bead 5).
- the depth of the lowering of the can plate relative to the edge of the can corresponds approximately to a distance that two layers of sliver lie on top of each other.
- the can plate has a structured surface.
- Figure 3 shows a flat can according to the invention in the inner structure.
- the can plate 140 is carried by a single pantograph 120, which is arranged centrally below the can bottom 140.
- struts 16, 160 are arranged in a horizontal position, which are rotatably mounted in the respective intersection.
- the ends of the struts are articulated to the respective opposite ring spring 110, 111.
- the articulated connection is achieved by the ends of the struts (16, 160) being formed into eyelets (16.1, 16.2; 160.1, 160.2). It is thus avoided in every position of the can plate and at high traversing speeds that the spiral spring bends out of its vertical position, as was previously caused by fluctuations in the fiber band column.

Description
Die Erfindung betrifft eine Flachkanne zur Aufnahme von Faserband, das von Karden oder Strecken abgeliefert wird. Die Flachkanne dient als Behältnis zur Aufnahme des abgelieferten Faserbandes sowie dessen Transport zu einer Weiterverarbeitungsmaschine der Spinnerei, durch welche das Faserband aus der Flachkanne wieder entnommen wird. Flachkannen haben im Gegensatz zu Rundkannen den Vorteil, daß sie sich platzgünstiger aufstellen und transportieren lassen. Weiterhin kann die Flachkanne mehr Faserband speichern als eine entsprechende Rundkanne. Problematisch ist jedoch gegenüber der Rundkanne das Befüllen und Entleeren der Flachkanne, denn das Faserband darf in keinerlei Weise in seiner Qualität beeinträchtigt werden.The invention relates to a flat can for receiving sliver, which is delivered by cards or draw frames. The flat can serves as a container for receiving the delivered sliver and its transport to a further processing machine of the spinning mill, through which the sliver is removed from the flat can again. In contrast to round cans, flat cans have the advantage that they can be set up and transported more cheaply. Furthermore, the flat can can store more sliver than a corresponding round can. However, filling and emptying the flat can is problematic compared to the round can, because the quality of the sliver must not be impaired in any way.
Bekannte Flachkannen bestehen aus 2 langgestreckten, parallelen Seitenwänden und 2 Stirnwänden. Alle Wände sind lotrecht zum Kannenboden angeordnet (EP 344 484).Known flat cans consist of 2 elongated, parallel side walls and 2 end walls. All walls are arranged perpendicular to the can bottom (EP 344 484).
Der Querschnitt der Flachkanne kann im einzelnen eine rechteckige Form, eine rechteckige Form mit abgerundeten Ecken (EP 344 484), eine rechteckige Form mit abgerundeten Endstücken (DE-OS 40 15 938, Fig. 3A), oder eine ovale Form sein. Die entsprechende Form nimmt auch der Kannenteller an, der bekannterweise beweglich ist und entsprechend dem Füllungszustand der Flachkanne gesenkt oder gehoben wird. Wie EP 344484 zeigt, war es für Flachkannen üblich, daß im Leerzustand der Kannenteller in Höhe des Kannenrandes positioniert ist. Die Positionierung wird durch Federn erreicht. Durch den Pantografen soll erreicht werden, daß der Kannenteller stets horizontal bleibt während seiner Hub- oder Senkbewegung.
Bei hohen Changiergeschwindigkeiten kommt es dennoch zu Kippbewegungen des Kannentellers.The cross section of the flat can can be a rectangular shape, a rectangular shape with rounded corners (EP 344 484), a rectangular shape with rounded end pieces (DE-OS 40 15 938, Fig. 3A), or an oval shape. The can plate, which is known to be movable, also takes on the corresponding shape and is lowered or raised according to the filling status of the flat can. As EP 344484 shows, it was customary for flat cans that the can plate is positioned at the level of the can rim when empty. The positioning is achieved by springs. The pantograph is intended to ensure that the can plate always remains horizontal during its lifting or lowering movement.
At high traversing speeds, the can plate still tilts.
Beim Befüllen mit Faserband wird üblicherweise die Flachkanne unter der Füllvorrichtung in Kannenlängsrichtung hin- und herbewegt, so daß durch diese Changierbewegung das Faserband zykloidenförmig auf dem Kannenteller in der Richtung von einer Stirnwand der Flachkanne zur anderen Stirnwand abgelegt wird. Mehrere abgelegte Faserbandlagen bilden mit zunehmender Füllung eine Bandsäule, die mittels ihres Eigengewichtes den Kannenteller langsam bis zum Anschlag am Kannenboden senkt. Der Kannenteller weist wie auch bei anderen Kannen üblich einen nach unten zur Standfläche (Kannenboden) abgewinkelten Rand auf und liegt mit seiner abgewinkelten Fläche bis auf einen kleinen Spalt an den Kannenwänden an. Nach dem Stand der Technik (EP 344 484) wird der Kannenteller an seinen beiden Enden von je einer Spiralfeder getragen, die den Kannenteller im unbelasteten Zustand beim oberen Kannenrand positionieren.When filling with sliver, the flat can is usually moved back and forth under the filling device in the longitudinal direction of the can, so that the sliver is deposited cycloid-shaped on the can plate in the direction from one end wall of the flat can to the other end wall by this traversing movement. With increasing filling, several stored layers of sliver form a band column which, by means of its own weight, slowly lowers the can plate up to the stop on the bottom of the can. As with other cans, the can plate has an edge that is angled downwards towards the base (can bottom) and lies with its angled surface except for a small gap on the can walls. According to the prior art (EP 344 484), the can plate is carried at both ends by a spiral spring, which position the can plate in the unloaded state at the upper edge of the can.
Die Positionierung des Kannentellers nach EP 457 099 (Spalte 7, 41.-44. Zeile) geht sogar davon aus, daß der Kannenteller noch etwas höher als der obere Kannenrand zu positionieren sei, nämlich bis in die Nähe der Unterkante des Drehtellers der Karde oder Strecke. So erzielt man bereits für die ersten Lagen des Faserbandes einen erforderlichen Anpreßdruck. Das hat jedoch den Nachteil, daß der Kannenteller der Flachkanne am Drehteller unmittelbar zu Füllungsbeginn schleift. Eine verschlissene Drehtelleroberfläche beeinträchtigt das abzulegende Faserband.The positioning of the can plate according to EP 457 099 (column 7, lines 41-44) even assumes that the can plate should be positioned somewhat higher than the upper edge of the can, namely up to the vicinity of the lower edge of the rotary card or Route. In this way, a necessary contact pressure is achieved for the first layers of the sliver. However, this has the disadvantage that the can plate of the flat can grinds on the turntable immediately at the start of filling. A worn turntable surface affects the sliver to be removed.
Mit wachsender Höhe der Faserbandsäule, die aus einer Vielzahl von aufeinanderliegenden Faserbandlagen besteht, wächst deren Masse. Insbesondere mit Auftreffen der Flachkanne an den jeweiligen Umkehrpunkt der Changierung, tritt der Effekt ein, daß die Faserbandsäule infolge ihrer Massenträgheit in Richtung der jeweiligen Stirnseite schwankt. Dabei schwankt die Faserbandsäule in ihrer Gesamtheit. Dieses Schwanken ist störend, da es die noch laufende Faserbandablage beeinflußt. Das führt nicht nur zu Dichteveränderungen des Faserbandes in Nähe der Stirnseite gegenüber anderen Ablagepositionen, sondern es kann auch vorkommen, daß Faserbandschlingen an der Stirnseite durch das Schwanken der Faserbandsäule in den momentanen Spalt zwischen Faserbandsäule und Kannenwand rutschen und verklemmt werden, was bei späterem Bandabzug die Bandbruchgefahr erhöht. Das Schwanken der Faserbandsäule verursacht weiterhin ein unerwünschtes Kraftmoment auf die Kannenwand und den Kannenteller.With increasing height of the sliver column, which consists of a large number of layers of sliver lying on top of each other, their mass increases. Especially when the flat can hits the reversal point of the traversing, the effect occurs that the Sliver column fluctuates due to its inertia in the direction of the respective end face. The entire sliver column fluctuates. This swaying is annoying because it affects the sliver storage that is still running. This not only leads to changes in the density of the sliver near the front side compared to other storage positions, but it can also happen that sliver loops on the front side slip and become jammed in the current gap between the sliver column and the can wall, which is the case when the sliver is pulled off later Belt breakage risk increased. The swaying of the sliver continues to cause an undesirable moment of force on the can wall and the can plate.
Um diesem Nachteil entgegenzuwirken, wird nach EP 344 484, Figur 1 und 2 vorgeschlagen, an den Innenseiten der länglichen Seitenwände jeweils einen Pantografen (auch Scherengitter oder Nürnberger Schere genannt) anzuordnen, die eine Parallelführung des Kannentellers zur Wandung sichern sollen. Das ist jedoch ein erhöhter konstruktiver Aufwand, der eine Schieflage des Kannentellers bei hohen Changiergeschwindigkeiten der Flachkanne nicht sicher vermeidet.In order to counteract this disadvantage, it is proposed according to EP 344 484, FIGS. 1 and 2, to arrange a pantograph (also called scissor lattice or Nuremberg scissors) on the inner sides of the elongated side walls, which are intended to ensure parallel guidance of the can plate to the wall. However, this is an increased design effort that does not reliably avoid an inclined position of the can plate at high traversing speeds of the flat can.
Die sich an den Längsrändern des Kannentellers symmetrisch gegenüberliegenden Pantografen, können nicht verhindern, daß der Kannenteller bei erhöhten Changiergeschwindigkeiten zum Kippen in Richtung seiner Längsachse neigt. Es besteht die Gefahr des Verkantens gegenüber der Wandung. Mit dem Kippen des Kannentellers besteht aber auch der Nachteil, daß die einzelne schlagartig belastete Spiralfeder aus ihrer Vertikalachse ausknickt.The pantographs, which are symmetrically opposite each other on the longitudinal edges of the can plate, cannot prevent the can plate from tending to tilt in the direction of its longitudinal axis at increased traversing speeds. There is a risk of tilting against the wall. With the tilting of the can plate there is also the disadvantage that the single, suddenly loaded spiral spring bends out of its vertical axis.
Die genannten Probleme haben bisher eine Einführung der Flachkanne in die Praxis verhindert, weil Liefergeschwindigkeiten wie sie bei der Rundkanne üblich sind, nicht realisiert werden konnten.The problems mentioned have hitherto prevented the flat can from being put into practice because delivery speeds as are customary with the round can could not be achieved.
Aufgabe der Erfindung ist es, beim Befüllen einer changierenden Flachkanne eine ordnungsgemäße Bandablage zu erzielen, die auch eine fehlerfreie Bandentnahme ermöglicht und zwar bei wirtschaftlichen Ablagegeschwindigkeiten, wie sie bei Rundkannen möglich sind.The object of the invention is to achieve proper tape storage when filling an oscillating flat can, which also enables error-free tape removal, and at economical storage speeds, as are possible with round cans.
Erfindungsmerkmal der Flachkanne ist, daß zwischen beiden Spiralfedern, die im Bereich der Stirnwandungen angeordnet sind, nur noch ein Pantograf angeordnet ist. Dieser einzelne Pantograf ist mittig zum Kannenboden angeordnet und in den Kreuzungspunkten dieses Pantografen sind horizontal Streben angeordnet, die drehbar im jeweiligen Kreuzungspunkt gelagert sind. Die Enden der Streben sind mit der jeweils gegenüberliegenden Spiralfeder gelenkig verbunden. Es wird somit in jeder Lage des Kannentellers und bei hohen Changiergeschwindigkeiten vermieden, daß ein Ausknicken der Spiralfeder aus ihrer vertikalen Lage erfolgt wie es durch Schwanken der Faserbandsäule hervorgerufen werden kann.The feature of the flat can is that only one pantograph is arranged between the two spiral springs which are arranged in the region of the end walls. This single pantograph is arranged in the middle of the jug bottom and at the crossing points this pantograph are arranged horizontally struts, which are rotatably mounted in the respective crossing point. The ends of the struts are articulated to the opposite spiral spring. It is thus avoided in any position of the can plate and at high traversing speeds that the spiral spring bends out of its vertical position, as can be caused by fluctuations in the sliver column.

Nach Fig.1 wird das Faserband vom Streckwerk zum Drehteller 2 geliefert. Die Lieferrichtung A des Faserbandes ist durch den Pfeil festgelegt. Der Drehteller 2 mit seiner Mündung des Bandführungskanal 1 rotiert stationär und wird von einem Maschinentisch 3 umgeben. Das Faserband verläßt die Mündung im Drehteller 2 und wird in der Flachkanne 4 in zykloider Form abgelegt. Die Ablage des Faserbandes ist nicht dargestellt. Jede einzelne Lage Faserband wird über die gesamte Breite und Länge des Kannentellers abgelegt. Der Kannenteller ist an der Kannenwandung beweglich angeordnet. Mit zunehmender Anzahl von Faserbandlagen muß sich der Kannenteller in Richtung Kannenstandfläche senken können.
Die Bewegung des Kannentellers kann beispielsweise durch einen extern gesteuerten Hubmechanismus vollzogen werden, der unter dem Kannenteller angeordnet ist. Der Hubmechanismus ist dabei im Eingriff mit dem Kannenteller.
Eine andere Möglichkeit ist, daß unterhalb des Kannentellers Federn angeordnet sind, die sich in Abhängigkeit von der Belastung des Kannentellers aus einer Ausgangsposition (leere Flachkanne) in eine abgesenkte Position begeben.According to Fig.1, the sliver is delivered from the drafting device to the
The movement of the can plate can be carried out, for example, by an externally controlled lifting mechanism which is arranged under the can plate. The lifting mechanism is in engagement with the can plate.
Another possibility is that springs are arranged below the can plate, which move depending on the load on the can plate from an initial position (empty flat can) to a lowered position.
Eine gefüllte Flachkanne wird zur Weiterverarbeitung des Bandes an eine Spinnmaschine transportiert. Die Breite einer Flachkanne entspricht deshalb der Arbeitsbreite einer einzelnen Spinnstelle.
Die Flachkanne 4 kann eine rechteckige oder ovale Grundfläche besitzen. Bevorzugt wird die rechteckige Grundfläche mit abgerundeten Ecken. Die Flachkanne 4 wird unterhalb des Drehtellers 2 einer Strecke oder Karde in Längsrichtung (entsprechend Doppelpfeil B) hin- und herbewegt (changiert), so daß der Kannenteller (in Figur 1 nicht dargestellt) über seine gesamte Länge mit Faserband belegt wird. Um die Flachkanne 4 changieren zu können, steht diese mit ihrer unteren Kannenwulst 50 auf einer Rollenbahn 6. Die Rollenbahn 6 besteht aus einer Vielzahl frei beweglicher Rollen, die nebeneinander angeordnet sind und mindestens dem Changierweg entsprechen. Auf dieser Rollenbahn 6 wird die Flachkanne 4 changiert. An der seitlichen Begrenzung der Rollenbahn 6 befinden sich beidseitig im Abstand zueinander Führungsrollen 7 und 70, (in der Regel mehr als zwei pro Seite), die der Flachkanne 4 im Standbereich eine Führung geben. Für den Zeitraum der Changierung wird die Flachkanne im oberen Drittel (unterhalb der oberen Kannenwulst 5) beidseitig durch je eine Changierhalterung 8 und 80 erfaßt, wobei diese Changierhalterungen mit einem Fahrgestell 9 in Verbindung stehen. Dieses Fahrgestell 9 besitzt einen hier nicht dargestellten Antrieb. Der Antrieb wird entsprechend einem Programm zur Befüllung der Flachkanne 4 gesteuert. Das Fahrgestell 9 wird entlang der Schiene 10 geführt.A filled flat can is transported to a spinning machine for further processing of the belt. The width of a flat can therefore corresponds to the working width of a single spinning station.
The flat can 4 can have a rectangular or oval base. The rectangular base with rounded corners is preferred. The flat can 4 is moved back and forth in the longitudinal direction (corresponding to double arrow B) underneath the
Figur 2 dokumentiert den bisher nach EP 344 484 bekannten Kannenaufbau wie er sich innerhalb der Kannenwandung 13 und unterhalb des Kannentellers 14 zeigt. Es sind je eine Spiralfeder 11 und an den Längsseiten je ein Pantograf 12 angeordnet.
Die Flachkanne wird hin- und herbewegt, d.h. changiert. Die Changiergeschwindigkeit im Umkehrpunkt auf den Wert Null abgebremst, um dann nach Durchlaufen des Umkehrpunktes unmittelbar auf Changiergeschwindigkeit zu beschleunigen. Im gegenüberliegenden Umkehrpunkt erfolgt der analoge Vorgang des Bremsens und Beschleunigens. Infolge des Bremsens und Beschleunigens kommt es bei bekannten Flachkannen nach Bildung der ersten Faserbandlagen für die stirnseitige Bandschlinge zu einem Verlagern derselben über den Kannenrand hinaus (s. Fig.2). Das ist sehr ungünstig, insbesondere im Hochgeschwindigkeitsbereich des Changierens.FIG. 2 documents the can structure known up to now according to EP 344 484, as can be seen within the can wall 13 and below the
The flat jug is moved back and forth, ie it changes. The traversing speed is decelerated to the value zero at the reversal point, in order then to accelerate to the traversing speed immediately after passing through the reversing point. In the opposite reversal point, the analogous braking and acceleration process takes place. As a result of the braking and accelerating, known flat cans after the formation of the first sliver layers for the end sling are displaced beyond the edge of the can (see FIG. 2). This is very unfavorable, especially in the high-speed area of traversing.
Um das Verlagern der ersten Faserbandlagen beim Changieren der Flachkanne zu vermeiden, wird der Kannenteller über seine gesamte Länge gegenüber dem Kannenrand (oberer Kannenwulst 5) abgesenkt.
Die Tiefe der Absenkung des Kannentellers gegenüber dem Kannenrand entspricht etwa einer Strecke, die zwei aufeinanderliegende Faserbandlagen einnehmen.In order to prevent the first sliver layers from shifting when the flat can is traversed, the can plate is lowered over its entire length relative to the edge of the can (upper can bead 5).
The depth of the lowering of the can plate relative to the edge of the can corresponds approximately to a distance that two layers of sliver lie on top of each other.
Um die Haftung zwischen Faserbandlagen und Kannenteller weiter zu erhöhen, erhält der Kannenteller eine strukturierte Oberfläche.
Es ist aber auch eine Ausführung einer genoppten Oberfläche denkbar.To further increase the adhesion between the sliver layers and the can plate, the can plate has a structured surface.
However, it is also conceivable to have a nubbed surface.
Figur 3 zeigt eine erfindungsgemäße Flachkanne im inneren Aufbau. Der Kannenteller 140 wird von einem einzelnen Pantografen 120 getragen, der mittig unterhalb des Kannenbodens 140 angeordnet ist.
In den Kreuzungspunkten des Pantografen sind in horizontaler Lage Streben 16, 160 angeordnet, die drehbar im jeweiligen Kreuzungspunkt gelagert sind. Die Enden der Streben sind mit der jeweils gegenüberliegenden Ringfeder 110, 111 gelenkig verbunden. Die gelenkige Verbindung wird erreicht indem die Enden der Streben (16, 160) zu Ösen (16.1, 16.2; 160.1, 160.2) ausgebildet sind. Es wird somit in jeder Lage des Kannentellers und bei hohen Changiergeschwindigkeiten vermieden, daß ein Ausknicken der Spiralfeder aus ihrer vertikalen Lage erfolgt wie es bisher durch Schwanken der Faserbandsäule hervorgerufen wird.Figure 3 shows a flat can according to the invention in the inner structure. The can plate 140 is carried by a
