摘要:
In a dobby drawing device in a weaving loom, the vertical displacement of a heddle frame is obtained with the aid of a single cable which is guided over first and second actuating levers to a set of springs. Two support shafts selectively support the actuating levers so the device may have a lifting or descending action.
摘要:
A drawing device for actuating the heddle frames of a weaving machine of the negative type including rocking levers which guide cables extending from the heddle frame to a return spring system. The rocking levers are mounted on shafts which are shiftable within elongated slots to thereby relax tension on the cables and spring system.

A modulator mechanism for actuating textile dobbies in looms which include a cage driven in rotation by the drive shaft of the loom and which have at least two oscillating supports provided with rollers which roll in contact with a fixed cam which is connected to the principal shaft of the dobby. Connecting rods are pivotally attached to the supports and to a web fixed to the dobby shaft so that the dobby shaft is intermittently driven in rotation as the connecting rods are oscillated by the supports.

In a spring system for dobbies and other weaving mechanisms of the negative type which includes hooking elements, each of the hooking elements includes, parallel to its edges which face the springs, a row of omega-sectioned openings which receive, by a lateral displacement along the axis of the opening, an endpiece of a shape to be seated within the openings.
摘要:
Adjustable clip elements for assembling oscillating arms of a weaving central system with engaging rods of a drawing system associated with heddle frames of a weaving loom. Each clip element includes a frame having pairs of lateral guides for two pairs of jaw assemblies provided in a slide block and associated with moveable wedges. The wedges are controlled with an adjusting mechanism arranged to urge one wedge towards the base of the slide block while urging the other wedge in the opposite direction.

In a spring system for a dobby in a weaving loom, the mobile hooking element which is fixed to a cable for moving a heddle frame includes laterally spaced plates which are slidably engageable with plates of adjacent spring systems to thereby prevent contact of the springs of the adjacent spring systems.
摘要:
A heddle frame having two uprights and two cross-rails interconnected by at least one brace extending in a direction generally parallel to the uprights. The brace includes a rod provided with a screw fastener at opposite ends thereof, two threaded members for being screwed onto one of the opposite ends of the rod, and first and second clamping members mounted to the opposite ends of the rod and the threaded members, respectively, for exerting a clamping locking force on a portion of each cross-rail wherein the locking force results from screwing the threaded members onto the opposite ends of the rod.
摘要:
An antifriction bearing of the roller type for a pulling system of weaving loom including two end plates secured to the inner race and positioned respectively and axially close to each flank of the rollers, end plates lying radially beyond the raceways and the end plates and the inner race being intended to be mounted between two lateral flanges. At least one end plate has a shape defining at least one cavity adjoining all or part of a flank of the rollers and able to accept a lubricant. The inner race has two lateral shoulders each one defining an axial bearing surface for each flange, and a width of the inner race with its lateral shoulders is substantially equal to a distance separating the outermost axial faces of the end plates.
摘要:
The invention relates to an antifriction bearing (30) of the roller (34) type for a pulling system for a weaving loom, comprising: an inner race (32) and an outer race (36) lying one on each side of the rollers (34) defining two raceways (321) and (361), two end plates (40, 42) secured to the inner race (32) and positioned respectively and axially close to each flank (34a, 34b) of the rollers (34), each end plate (40, 42) lying radially (Y) beyond the raceways (321, 361), the end plates (40, 42) and the inner race (32) being intended to be mounted between two lateral flanges (24a, 24b). At least one end plate (40, 42) has a shape defining at least one cavity (41, 43) adjoining all or part of a flank (34a, 34b) of the rollers (34) and able to accept a lubricant. The inner race (32) has two lateral shoulders (32a, 32b) each one defining an axial bearing surface (32e, 32f) for each flange (24a, 24b), and the width (11) of the inner race (32) with its lateral shoulders (32a, 32b) is substantially equal to the distance (12) separating the outermost axial faces of the end plates (40, 42).
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.
