Abstract

An appts. to cut and clamp yarns in a knitting machine, partic. flatbed knitters, is located within the needles, underneath their operating zone, and can be located at will and operated according to the fabric width being worked. The unit does not interfere with the operation of the slide, and fabric wastage at the sides is reduced.

Description

Fadenschneid- -Ansaug- und -Klemmvorrichtung Vorrichtung für Strickmaschinen, insbesondere Flachstrickmaschinen, die beiderseits des Arbeitsbereiches der Maschine zwischen den Nadelbetten angebracht ist zum Faden-Schneiden, -Ansaugen und -Klemmen. Thread cutting, suction and clamping device device for knitting machines, especially flat knitting machines on both sides of the work area of the machine is attached between the needle beds for thread cutting, suction and clamping.

Durch diese Vorrichtung ist es möglich, die gesteuerte Garneinlage für die Warenbreite am Warenanfang zu klemmen und am Ende der Warenbreite wieder abzuschneiden.With this device it is possible to use the controlled yarn insert for the width of the goods to be clamped at the beginning of the goods and again at the end of the width of the goods to cut off.

Vorrichtungen ähnlicher Art sind durch DAS 1 o15 176, 1 090 810, DOS 1 585 452, 1 585 361 und 1 943 893 bereits bekannt. Sie haben Jedoch den Nachteil, daß sie oberhalb des Nadelraumes angebracht und somit im Störbereich des Schlittens liegen.Devices of a similar type are available through DAS 1 o15 176, 1 090 810, DOS 1 585 452, 1 585 361 and 1 943 893 already known. However, they have the disadvantage that they are attached above the needle space and thus in the interference area of the slide lie.

Es ist nun die Aufgabe, eine Vorrichtung zu schaffen, die auch bei Maschinen mit Hubverstellung voll verwendungsfähig sind.It is now the task to create a device that also works with Machines with adjustable lift are fully usable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daI3 die Vorrichtung so ausgebildet ist, daß sie an Jeder beliebigen Stelle innerhalb des Nadelraumes der Maschine, an durch die Warenbreite bestimmte Positionen in Tätigkeit gebracht werden kann. So auch die Fadenklemmvorrichtung die unterhalb des Störbereichs der Nadeln liegt und der Maschenbilderkamm der beiden Nadelbetten den Einführtrichter der absaugenden Einzugsvorrichtung für geschnittene Fäden bildet.This object is achieved according to the invention in that the device is designed so that it is at any point within the needle space of the machine, brought into action at positions determined by the width of the goods can be. So also the thread clamping device that is below the interference area of the Needles and the stitch formation comb of the two needle beds the insertion funnel the suction device for cut threads.

Beim Arbeiten mit geschnittenen Garnenden ergibt sich bei den bisherigen Vorrichtungen ein systembedingter, mehr oder weniger breiter Rand unbrauchbaren Gestrickes. Diese Erscheinung wird durch das zyklische Klemmen bei Beginn der Strickreihen stark vermindert, so daß der Anteil unbrauchbaren Gestrickes wesentlich geringer ist.When working with cut yarn ends, the previous results Devices a system-related, more or less wide margin unusable Knitted fabric. This phenomenon is caused by the cyclic clamping at the beginning of the knitting rows greatly reduced, so that the proportion of unusable knitted fabric is significantly lower is.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen: Figur 1 in vereinfachter Form eine Flachstrickmaschine mit beiderseits dem Gestrick stehenden Vorrichtungen (wo), sowie die Ansaugschläuche (11).An embodiment is shown in the drawing and will described in more detail below. The figures show: FIG. 1, in simplified form, a flat knitting machine with devices on both sides of the knitted fabric (where), as well as the suction hoses (11).

Figur 2 zeigt eine Klemmeinrichtung (20), die unterhalb der Nadelbetten (21) liegt. Das federnde Klemmstück (22) liegt innerhalb des Absaugkanals und ist mit der zwangsgesteuerten Achse (32) fest verbunden.Figure 2 shows a clamping device (20) below the needle beds (21) lies. The resilient clamping piece (22) lies within the suction channel and is firmly connected to the positively controlled axis (32).

Figur 3 zeigt die Abschneidvorrichtung (31) welche am Schlitten angebracht und durch Auflaufen auf Schaltstücke (32) ztrangsgesteuert ist.Figure 3 shows the cutting device (31) which is attached to the carriage and is ztrangs-controlled by running on contact pieces (32).

Die Zwangssteuerung erfolgt über das Schaltstück (32) und weitere Zwischenglieder zu Achse (23). An der Oberseite der Klemmvorrichtung ist der Gegenhalter der Abschneidvorrichtung (24) fest angebracht.The forced control takes place via the contact piece (32) and others Intermediate links to axle (23). The counter holder is on the top of the clamping device the cutting device (24) firmly attached.
