Abstract

A mangle for circular knitted fabric has a circular spreader is combined with several mangling stations circularly arranged around the spreader for the removal of treatment liquor from tubular fabrics. In order to protect the fabric against excessive squeezing, an upper roller head is entirely avoided by confining the circular spreader in the horizontal direction exclusively by the mangling stations. The vertical support of the spreader is provided fully by the mangling stations if the mangling rollers are mounted in positions slanting to the vertical. If the mangling rollers are not mounted in slanted positions it is preferred that a lower roller head operated by a lifting mechanism assists the mangling rollers in supporting the spreader (8) vertically. In both instances an upper roller head becomes unnecessary.

Ein Breithalterkopf zur Fixierung und zur Aufnahme des Eigengewichts des Breithalters 8 ist nicht mehr notwendig.According to this embodiment, an additional spreader head 31 is used for receiving the own weight of the spreader 8 is dispensed with. The central spreader 8 is through the crushers 13 fixed in the horizontal position and the weight of the spreader by a slight inclination (V position) of the squeeze rollers 23a, 26a at an angle α also taken over by the crushing machines. The spreader 8 hangs freely in the outer nip rollers 23a. A spreader head for fixing and for taking up the Dead weight of the spreader 8 is no longer necessary.

Zur motorischen Breitenverstellung des Breithalters ist in bekannter Weise eine Hubvorrichtung 17 mit Fixierrollen 10 vorgesehen, in welchen der Breithalterkopf 11 gelagert ist, wobei der Breithalterkopf 11 über ein Drehlager 22 mit dem Innenrohr 19b des Trägers 19 verbunden ist.For the motorized width adjustment of the spreader is a known Lifting device 17 is provided with fixing rollers 10, in which the spreader head 11 is mounted is, the spreader head 11 via a rotary bearing 22 with the inner tube 19b of the carrier 19th connected is.

Durch die Schrägstellung der Quetschwalzen 23a, 26a, 26b im Winkel α ist der Umfang der Ware 1 im unteren Bereich des Quetschwerks etwas kleiner als oben. Dies kann den gleichmäßigen Transport der Ware stören, so daß die Breitenunterschiede durch eine entsprechende gegensätzliche Schrägstellung der Ausbreitrollen 12 in einem Winkel β ausgeglichen werden.
Die Schlauch-Wirkware 1 wird nach dem Quetschen über eine Walze 34 nach oben abgezogen, ohne daß weitere, unerwünschte Drücke auf die Ware wirken.Due to the inclined position of the squeeze rollers 23a, 26a, 26b at an angle α, the circumference of the goods 1 in the lower region of the squeeze mechanism is somewhat smaller than above. This can interfere with the uniform transport of the goods, so that the differences in width are compensated for by a corresponding opposite inclination of the spreading rollers 12 at an angle β.
After being squeezed, the tubular knitted fabric 1 is pulled upwards by means of a roller 34 without further, undesirable pressures acting on the fabric.

Figur 4 zeigt eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung, wobei wiederum die Quetschwerke und die Ausbreitrollen in eine Ebene geklappt sind. Diese Anordnung entspricht im wesentlichen der Anordnung gemäß Figur 3, verzichtet jedoch ganz auf den Breithalterkopf 11 und die Hubvorrichtung 17 zur Breitenverstellung der Breithalteeinrichtng 8.Figure 4 shows a further embodiment of the device according to the invention, wherein again the crushers and spreading rollers are folded into one plane. This The arrangement essentially corresponds to the arrangement according to FIG. 3, but is dispensed with entirely on the spreader head 11 and the lifting device 17 for width adjustment of the Spreading device 8.

Die Breithalteeinrichtung 8 hängt frei in den äußeren Quetschwalzen 23a. Im oberen Bereich der Breithalteeinrichtung ist im Außenrohr 19a des Trägers 19 eine Kolben-Zylindereinheit angeordnet, deren Kolbenstange 33 gelenkig mit den oberen Abstützungen 20a der Breithalteeinrichtung 8 verbunden ist. Durch vertikale Bewegung der mit dem Zylinderkolben verbundenen Kolbenstange in den Richtungen 18, werden die Abstützungen 20a mehr oder weniger nach oben gezogen und dadurch die Breite der Breithalteeinrichtung 8 verstellt.The spreader 8 hangs freely in the outer nip rollers 23a. In the upper area the spreader is a piston-cylinder unit in the outer tube 19a of the carrier 19 arranged, the piston rod 33 articulated with the upper supports 20a of the Spreader device 8 is connected. By vertical movement of the with the cylinder piston connected piston rod in the directions 18, the supports 20a are more or pulled less up and thereby adjusted the width of the spreader 8.

Figur 5 zeigt wieder die Quetschwerke und die Ausbreitrollen in eine Ebene geklappt. In den Anordnungen gemäß Figuren 3 und 4 kann es vorkommen, daß die Breithalteeinrichtung bei zu starker Schrägstellung der Quetschwerke unter dem Druck der Ware hochsteigt, was natürlich nicht erwünscht ist.FIG. 5 again shows the squeezing mechanisms and the spreading rollers folded into one plane. In the Arrangements according to Figures 3 and 4, it can happen that the spreader at too high inclination of the squeeze rises under the pressure of the goods, which is of course not desired.

Um dieses zu verhindern ist es nun vorgesehen, die Quetschwerke in vertikaler Richtung in zwei Gruppen aufzuteilen. Es sind nun zwei Sätze von Quetschwerken, bestehend aus Quetschwalzen 23b,26b bzw. 23c,26c, vertikal übereinander angeordnet, von denen die unteren Quetschwalzen 23c,26c in V-Stellung und die oberen Quetschwalzen 23b,26b in gegensätzlicher Stellung (umgekehrter V-Stellung) angebracht sind. Dazu ist eine zusätzliche Walzenaufnahme 35 in der Mitte der Anordnung vorgesehen, welche die beiden Quetschwalzen 26b,26c aufnimmt. Gleichzeitig ist eine zusätzliche Kolben-Zylindereinheit 27a vorgesehen, an welcher die beiden Quetschwalzen 23b,23c drehangetrieben befestigt sind. Durch die sich "aufhebende" Schrägstellung der Walzensätze 23b,26b und 23c,26c wird die Breithalteeinrichtung 8 in den Quetschwerken in allen Richtungen fixiert.
Eine zusätzliche Schrägstellung der Ausbreitrollen 12 ist nicht mehr notwendig. In order to prevent this, it is now intended to divide the squeezing units into two groups in the vertical direction. There are now two sets of squeeze units, consisting of squeeze rollers 23b, 26b and 23c, 26c, arranged vertically one above the other, of which the lower squeeze rollers 23c, 26c in the V position and the upper squeeze rollers 23b, 26b in opposite positions (reverse V- Position) are attached. For this purpose, an additional roller holder 35 is provided in the middle of the arrangement, which receives the two nip rollers 26b, 26c. At the same time, an additional piston-cylinder unit 27a is provided, to which the two squeeze rollers 23b, 23c are fastened in a rotationally driven manner. Due to the "canceling" inclined position of the roller sets 23b, 26b and 23c, 26c, the spreading device 8 is fixed in the squeezing units in all directions.
An additional inclination of the spreading rollers 12 is no longer necessary.
