摘要:
In a rapier driving device (10a, 10b) in a rapier loom (1), which includes designated driving means (30) by which a driving wheel (6, 7) for reciprocating a rapier head (2, 3) is driven independently of a main driving motor of the loom (1), the driving means (30) includes a plurality of driving motors (M1, m1, m2, m3, m4).
摘要:
Die Erfindung betrifft eine Webmaschine mit einer Greiferstange (10), welche mit einem Antriebsrad (16) in Eingriff steht und von diesem reversierend antriebbar ist, und mit einer pneumatischen Führungseinrichtung (20) zum Führen und Lagern der Greiferstange. Eine Verbesserung der Führungseigenschaft wird erfindungsgemäß dadurch erreicht, dass die pneumatische Führungseinrichtung wenigstens zwei voneinander getrennt gelagerte Luftlager (22a,22b) aufweist, welche beabstandet von der Eingriffsstelle des Antriebsrades angeordnet sind. Für diese Webmachine ist eine pneumatische Führungseinrichtung mit einer Führungsfläche vorgesehen, an welcher ein poröses luftdurchlässiges Material angeordnet ist.
摘要:
This invention relates to a device for driving and guiding a rapier of a weaving machine, comprising a rotatable drive wheel (1) provided for driving a rapier rod (14) in a back and forth movement and a guide channel formed by adjustable guide bodies (10), (11) in order to guide the said rapier rod (14) according to a guide path in co-operation with the drive wheel (1), the guide bodies (10), (11) being part of a guide unit (9) which, as a whole, is adjustable in order to modify the distance between the guide path and the rotation shaft (2) of the drive wheel (1), and where the drive wheel (1) is continuously adjustable in the longitudinal direction of its shaft (2). With this device the clearances of the rapier rod with respect to the drive wheel can be performed easily, rapidly and with great precision, so that this device is able to work with a minimum development of heat and wear.
摘要:
A highly abrasion-resistant rapier band having a high bending rigidity across the width direction thereof even after abrasion, and a long life is provided. The rapier band (12) has a laminated structure including a core member (28) and a pair of woven fabrics for preventing abrasion (19, 20). The woven fabrics for preventing abrasion (19, 20) are of satin weave consisting of warp threads (T) and weft threads (Y). A reinforcing compensation layer (t1) made of fibers for compensating for the bending rigidity across the width direction of the rapier band (12) lies beneath each woven fabric for preventing abrasion (19, 20), with the surface of the reinforcing compensation layer (t1) away from the center (S1) of the thickness (S) of the rapier band (12).
摘要:
Gripper guide for double-gripper weaving machines, comprising two bearing arms (5) and (5') running above one another and adjustable individually in the warp direction, an L-shaped guide strip (7), (7') fixed to each bearing arm (5), (5') so that it is adjustable in height, and in front of each guide strip (7), (7') a straight guide strip (8), (8') which with each first-mentioned guide strip (7), (7') forms a U-shaped channel for the gripper bars (4), (4'), so that the latter cannot swing, the straight guide strips (8), (8') being adjustable both in the warp direction and in height, and being easy and quick to remove from their guide position, for example through a hinged connection to the respective bearing arms (5) and (5'), which permits the upper guide strip (8) to flap up and the lower guide strip (8') to flap down, while at the level of the drive gear wheels (2), (2') on the guide strips (8) and (8') at least one roller (20), (20') is disposed on a vertical shaft (21), in order to guide the gripper bars (4), (4').
