摘要:
The invention relates to a transmission rod (3) which is used to transfer drive forces, which can change directions, to a heald frame. According to the invention, two partial sections (3a, 3b), wherein one of them comprises a connection element (21), are provided. The connection element is provided with a finger element (2) in the longitudinal direction thereof, which is associated with a tooth-like, tensile receiving element of a connection element (23) of the other part section (3b).

Improved lubrication device for the bearings of the leverages actuating the heald frames in a weaving loom, of the type in which one or more mobile-position bearings (2) are supported by planar joints (A) tilting about fixed-position bearings (1) on respective support shafts. At least part of the bearings (1, 2) of each of said joints is joined through nylon tubes (4) to a dispenser (3) dispensing a lubricating matter integral with joint (A), while a cartridge (5) full of said lubricating matter is removably connected to the dispenser (3).
摘要:
Ein neuartiges Schaftgetriebe zum harmonischen Ein- und Ausschalten von einzelnen Webschäften und zur Ableitung deren Bewegung aus der Drehbewegung einer einzigen Eingangswelle weist eine Kupplungsanordnung mit zwei Eingangselementen auf. Während eines der Eingangselemente dazu dient, das Ausgangselement der Kupplungsanordnung dauerhaft anzutreiben, dient das andere Eingangselement lediglich dazu, das Ausgangselement kurzzeitig auf das erste Eingangselement zu synchronisieren. Die Umschaltung erfolgt in den kurzen Synchronphasen in ausgewählten Winkelbereichen, die dem oberen oder unteren Umkehrpunkt des Webschafts entsprechen. Derartige neue Schaftantriebe benötigen keine Rast der Eingangswelle oder des Schaftantriebs zum Umschalten.
摘要:
Ce mécanisme comprend une bielle tubulaire (3) à section aplatie qui, pour son attelage à au moins un levier oscillant de liaison (4), est pourvue d'au moins un embout (8) comprenant deux flasques (10, 11), prévus pour être disposés de part et d'autre de ce levier en étant articulés sur celui-ci, et au moins une partie (9) apte à pénétrer et à être immobilisée dans une extrémité (3 a ) de la bielle (3). Cette extrémité (3 a ) de bielle (3) est pourvue, sur sa surface interne (34 a ), de reliefs (33 b , 34 b ) aptes à coopérer avec des surfaces d'appui (91 a , 92 a ) prévues sur la partie (9) précitée pour l'immobilisation de cette partie (9) dans l'extrémité (3 a ) de la bielle (3).
摘要:
The invention relates to a bearing, preferably for a shaft lever in a weaving machine, having an inner bearing ring (1) and an outer bearing (4), which execute a limited rotating movement in relation to each other. The interior of the bearing is sealed by two sealing rings (10) fitted on the face of the bearing. Durable and resistant sealing of the bearing is achieved in that both sealing rings (10) are connected to the outer bearing ring (4) via a rigid outer retaining ring (12). The sealing ring (10) stretches radially inwards from this outer retaining ring (12), in the form of a membrane, and ends in a bulge (11). The sealing ring (10) is fixed in a cavity (8) in the inner bearing (1) by means of this bulge (11).
摘要:
The invention concerns an articulated head (5) of the control linkage for the heald frames of looms, operating on the control lever (2) of a shedding machine, comprising: a stiff long guide (8); a drawer (9) longitudinally sliding therein with precision, a portion of the control lever (2) crossing the guide (8) and the drawer (9); and at least first and second positive locking means, positioned opposite and acting on the two sides (S1, S2) of said lever (2). In said head (5) the first positive locking means comprise wedge-shaped elements (100, 101), apt to impart a direct pressure substantially transversal to the guide (8) and towards its longitudinal axis (a-a'), under the action of the adjacent side (S2) of said control lever (2) pressed on said wedge-shaped elements (100, 101) by the action of the second positive locking means.
摘要:
Le bâti (15) de l'agrafe comporte des paires de guides latéraux (16 a , 17) pour deux ensembles de mors (23, 24) prévus dans l'étrier (18) et associés à des coins de manoeuvre (22, 25). La commande de ceux-ci est opérée à l'aide d'une vis (20) portée par une entretoise (19) fixée entre les ailes de l'étrier (18) et agencée pour pousser le coin (25) vers le fond dudit étrier tout en tirant le coin (22) dans le sens opposé.

Die Einrichtung enthält einen Hohlkörper (11), ein Halteglied (12), eine Spannanordnung (13) und zwei Klemmorgane (15), die zwei ausserhalb des Hohlkörpers liegende Klemmstellen (38, 39) bilden. Die Abstützung der Einrichtung wird verbessert und eine Erweiterung der Klemmbereiche ermöglicht.
摘要:
A sliding nut (20) for a dobby lever of a textile loom, which can be inserted into a main lever (11) which consists of a pair of parallel flat sides (12,13), separate but fixed to each other, where the sliding nut (20) comprises a body which can be inserted between the sides (12,13), at one end of which is a hole (22) suitable for receiving a joint which can be connected to a driving bar and at the other end a relative blocking device for the sides, the body being shaped at the second end (25) to receive sloping surfaces on which there are wedge-shaped elements (28), in a complementary slanting position, which can be inserted into a box-shaped container (30) and acting upon the sides, a screw element (34) being applicable to the box as a blocking device to determine the performance of the wedge-shaped elements (28) with respect to the sloping surfaces and sides at the main lever.
