Problems solved by technology

This prior art performs satisfactorily, but requires the use of a large number of electric actuators as each actuator controls one or a small number of healds so far
If several healds are controlled by the same actuator, the relative inclination angles of the healds connected to these heddles must be small to limit friction, which affects the positioning of the actuator and may cause, in some constructions, The unit requires a lot of space

Embodiment Construction

[0026] The electric rotary actuator 1 shown in Fig. 1 is a servo motor with a splined output shaft 11, X-X' denotes the longitudinal geometric axis of the output shaft 11. This axis is parallel to the direction D of the weft threads of the loom.

[0027] In the vicinity of this actuator 1 there are other actuators 1' of the same type, these actuators 1' are shown in dot-dash lines in FIG. .

[0028] Mounted on the shaft 11 are a plurality of identical modules 2, each said module 2 comprising a pinion 21 arranged around the shaft 11 and having a central opening allowing the pinion to engage with the splines of the shaft to thereby Driven to rotate about axis XX'. The modules 2 can slide on corresponding shafts 11 with reduced play. Each module 2 also comprises a spur rack 22 substantially parallel to an axis Z-Z' inclined relative to the horizontal when the loom M is in its normal configuration for use.

[0029] Each module 2 also comprises a unitary / integral housing 23 in ...

Abstract

The invention relates to a shedding device comprising at least one electric rotary actuator having an output shaft ( 11 ) that is designed to rotate a pinion ( 21 ) which is engaged with a rack ( 22 ), said rack being connected to a control heald ( 3 ) of a warp end ( 4 ) by means of a load transfer element ( 24 ).

Description

technical field [0001] The present invention relates to a device for forming a shed in a loom of the Jacquard type. Background technique [0002] In Jacquard-type weaving systems, it is known to drive in opposite phases two multi-hooks each bearing a hook adapted to move vertically via a pulley or slider and tackle mechanism, connected to the heald / harness cord. A knife box (griffe) or a frame for horizontal lifting of the knife. [0003] It is also known, for example from EP-A-0933456, to alternately move the heddle of a Jacquard machine, using an electric rotary actuator-controlled pulley for more or less winding a cord-like element. This prior art performs the function satisfactorily, but as hitherto each actuator controlled one or a small number of heddles, requiring the use of a large number of electric actuators. If several healds are controlled by the same actuator, the relative inclination angles of the healds connected to these heddles must be small to limit frict...
