摘要:
A drawing mechanism for a weaving loom including a tubular connecting rod with flattened cross-section which is coupled to at least one oscillating connecting lever by at least one connector including two plates disposed on either side of the lever and being articulated thereon and at least one insert part adapted to fit within and be secured to an open end of the connecting rod. The connecting rod end is provided, on its inner surface, with elements in relief adapted to cooperate with bearing surfaces provided on the insert part for securing the insert part in the open end of the connecting rod.

A connecting device for connecting a motion transmission element to a heddle frame in a weaving loom wherein the connection device includes a tenon member and mortise member which are cooperatively engaged with respect to one another. The tenon member includes a nut mounted to the transmission element, an anchoring block through which the transmission element extends and which cooperates with surfaces of the mortise member, a bush through which the transition element passes and which bush cooperates in rotation with the nut and which also includes a counter-nut for securing the bush against the anchoring block.
摘要:
A connector for a drawing mechanism including at least one tubular connecting rod of flattened cross section for connecting the connecting rod to a rocking lever of a heddle mechanism wherein the connector includes two cheeks adapted to be disposed on opposite sides of the lever and where at least two generally parallel pins include first ends which are welded to inner faces of the cheeks. The pins include second ends adapted to be connected within the connecting rod and which second ends are spaced from the first ends by a deformable portion of each pin.

A shaft driving device for driving a plurality of heald shafts arranged in parallel comprises respective shaft raising elements each associated with a heald shaft and provided with a linkage and a plurality of lever elements connecting the linkage to the respective heald shaft. Drive apparatus are arranged on opposite ends of the heald shafts. The drive apparatus are drivingly connected to ends of juxtaposed shaft raising elements which face the drive apparatus. The cross-sectional dimensions of each linkage in the direction of the neighboring shaft raising element can be larger in the end of the shaft raising element facing the drive apparatus than in the end facing away from the drive apparatus.

A shoe for protecting pulleys in a drawing system associated with a heddle frame of a weaving machine. The shoe has an inner portion of concave profile from which a projection extends so as to be receivable within a groove of the pulley. The shoe also includes two outer segments in one of which a groove is provided having a bottom which is oriented tangentially to the groove of the pulley so that the cable guided therein will be directed generally tangentially with respect to the groove of the pulley.
摘要:
A device for coupling two outer parts (3) to a third part (2) disposed therebetween. The device includes a plurality of fasteners 7 each threadably mounted to an opening (9) in one of the outer parts and a cylindrical recess (6a) in the third part. Each fastener 7 has a conical head 7a that rests against the opening in the outer part. The outer parts project over the cylindrical recess so that an annular cavity is formed between the head of the fastener and the third part. Thus, the head of the fastener elastically deforms the outer part into the annular cavity so that additional forces may be transmitted from the outer part to the third part. In addition, the inner surface of each outer part is parallel to the third part so that the third part may be replaced without any effective movement of the outer parts.
摘要:
Connectors which are removably mounted within connecting rods which are used to assemble the rods to levers for controlling the movement of heddle frames in a weaving loom and which include expandable jaws for securing the connectors within the rods.
摘要:
A drawing mechanism incorporating rocking levers interposed between a weaving mechanism and the heddle frames of a weaving loom wherein each of the rocking levers for coupling the connecting rods includes a lateral element which defines a lubrication conduit joining the interspace of the ball bearings to an opening made in the levers for mounting to a coupling pivot.
摘要:
A system for fastening the drawing cables on the suspension levers of textile dobbies of the negative type, wherein the levers include flanges to which mounting eyes connected to the cables are secured. The cables are guided in grooves formed in a bearing pad which is cooperatively seated against the outer edge of the levers.

A connector for joining a wire or a second machine element (associated with a harness frame, for example) to a first machine element (a Dobby machine, for example) has a bracket including spaced-apart opposed side plates, a bearing and a wire connecting mechanism. The bearing is unmovably engaged with a mating holding portion connected to the first machine element and includes a body member made from synthetic resin, and which body member defines a shaft hole having a supporting shaft rotatably inserted therethrough, and a lubricant storing recess in the upper portion thereof. A lubricant retaining member is inserted in the recess to keep a lubricant infiltrated in the lubricant retaining member. A bottom surface of the recess is open to a lubricant feeding slot of a small diameter which extends to the inner circumferential surface of the shaft hole of the bearing. On the other hand, the wire connecting mechanism includes three rest members spaced at suitable intervals in the intersecting direction of the opposing direction of both side plates, wire jointing members connected to one end portion of a connecting wire and detachably inserted between every two rest members, anchoring members pivotally engaged therewith so that the anchoring members are disengageably mated with the wire jointing members to prevent the detachment of the wire jointing members from the rest members, and fixing bolts detachably screwed to the anchoring members and the rest members to hold the anchoring members in engagement with the wire jointing members.
