摘要:
A compacting device (2) of a fibre web comprises an intermediate body (100,102) slidingly couplable to a support body (80) and a suction mouth (30) couplable, preferably slidingly, to the intermediate body (100,102). In addition, the devices preferably envisages that upon transit between an intermediate duct (104) of the intermediate body (102) and a side branch (89) of the support body (82) and/or upon transit between the inner chamber (121) of the mouth (30) and the intermediate duct (104) a widening of the through section of the air in the air suction direction is made.
摘要:
Es ist ein Käfigaggregat für ein Streckwerk einer Textilmaschine beschrieben. Das Käfigaggregat enthält einen Käfig zum Führen zweier einen Druckwalzenzwilling eines Streckwerks umschlingenden Führungsriemchen. Das Käfigaggregat enthält ferner eine austauschbare Käfigstütze und ein austauschbares Führungselement zum Führen eines Faserverbandes. Die Käfigstütze und das Führungselement sind lösbar aneinander befestigt und am Käfig angebracht. Die Käfigstütze und das Führungselement können jeweils wenigstens eine Abstützfläche aufweisen, die direkt am Käfig anliegt.
摘要:
The invention relates to a pneumatic compaction device (10) and to a method for pneumatically compacting a fiber assembly (2) which was preferably stretched in the area of a drafting line (1) of a spinning machine. The inventive compaction device comprises transport means (15) for the fiber assembly (2) and a cover (30) that is provided with at least one guide (31, 31') extending in the direction of feed of the fiber assembly (2) for the air that effects compaction. The invention thus provides an excellent device and method for compacting the fiber assembly.
摘要:
Provided is a drafting apparatus to achieve a longer lifetime in service of a front roller therein, to realize labor-saving in spinning operation and to improve an operation efficiency. A drafting apparatus D includes a pair of fiber feeding means for transporting a sliver F to the downstream side while grasping the sliver F at a nip point N and stretching it, characterized in that one of the pair of fiber feeding means is constituted of an endless belt 12, and the pair of fiber feeding means is provided so that a feeding force acting in a direction of feeding the fiber bundle with the endless belt is concentrated on the nip point.
摘要:
The device comprises, at the outlet of the final pair of rollers (4) of a spinning machine draw-frame, a tubular element (20) which is parallel to the axis of said rollers (4), is connected to a source of vacuum, and is provided with multiple transverse grooves (7), on which there runs a band (9) provided with small perforations for receiving, in turn, through its face remote from said tube, the sliver (5) leaving the draw-frame, and performing the transverse condensing of said sliver (5) as it adapts to the empty grooves (7) through the perforated band (9), the tubular element (20) having a gently curved structure in the adaptation region of the perforated band (9), and is characterised in that it comprises a drive cylinder (13) inside the perforated band (9), which receives a tangential upper roller (14), which has resilient characteristics and of which the drive cylinder (13) is actuated by a longitudinal shaft common to the various drawing units of the machine.

Die Erfindung betrifft bezieht sich auf ein Streckwerk bei einer Textilmaschine, insbesondere Ringspinnmaschine, mit einem Eingangswalzenpaar (2), einem Ausgangswalzenpaar (4) sowie einem zwischen dem Eingangs- und Ausgangswalzenpaar angeordneten Mittelwalzenpaar (3), deren Walzen jeweils von Riemchen (8,9) umschlungen sind, die über Umlenkelemente laufen. Erfindungsgemäß ist zwischen der Unterwalze (3.2) des Mittelwalzenpaares und der Unterwalze (4.2) des Ausgangswalzenpaares ein Freilauf (20) angeordnet, durch dessen Sperrwirkung ein Vorlauf der Unterwalze (3.2) des Mittelwalzenpaares gegenüber der Unterwalze (4.2) des Ausgangswalzenpaares verhinderbar ist.
