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, and X-X' represents the longitudinal geometric axis of the output shaft 11. The axis is parallel to the direction D of the weft of the loom.

[0027] Other actuators 1'of the same type are arranged near the actuator 1. These actuators 1'are shown in dashed-dotted lines in FIG. 1, and their output shafts (not shown) are parallel to the shaft 11. .

[0028] A plurality of identical modules 2 are installed on the shaft 11. Each module 2 includes a pinion gear 21 arranged around the shaft 11 and having a central opening, which allows the pinion gear to cooperate with the spline of the shaft. It is driven to rotate around the axis X-X'. The module 2 can slide on the corresponding shaft 11 with a reduced gap. Each module 2 also includes a straight rack 22 substantially parallel to an axis Z-Z' inclined with respect to the horizontal direction when the loom M is in the normal use config...

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 invention relates to a device for forming a shed in a jacquard loom. Background technique [0002] In the jacquard-type weaving system, it is known to drive two respective supports in opposite phases, which are adapted to vertically move the hook connected to the harness / harness cord through a pulley or slider and a tackle mechanism. A knife box (griffe) or horizontal knife frame. [0003] For example, it is also known from EP-A-0933456 to use a pulley controlled by an electric rotary actuator for more or less winding a cord-like element to alternately move a heddle of a jacquard. The functions performed by the prior art are satisfactory, but since each actuator controls one or a small number of healds so far, a large number of electric actuators have to be used. If some healds are controlled by the same actuator, the relative inclination angle of the healds connected to these healds must be small to limit the frictional force, which will affect the pos...
