Embodiment Construction

[0019] figure 1 The weaving machine M shown schematically in , is equipped with a shedding device 10 comprising two sets of blades or broaches.

[0020] The first set of blades 11 is supported by two crossbars / cross members 12 forming a first bracket, while the second set of blades 11' is supported by the other two crossbars 12' forming a second bracket.

[0021] The blades 11 and 11' are adapted to move in a vertical oscillating motion indicated by the double arrow F1, which enables the hooks (not shown) to move between their respective top dead center and bottom dead center positions for controlled passage The movement of the heddle 13 with the harness 14 connected to a hook is well known in the technical field of jacquard looms.

[0022] The bars or brackets 12 and 12' and the blades 11 and 11' interacting therewith are arranged between two plates 20 and 21 to be connected to a frame B.

[0023] There is an input shaft 30 extending between the plates 20 and 21 and the sha...

Abstract

The shed forming device according to the invention for a weaving loom of Jacquard type comprises two series of knives actuated by a single input shaft animated by a continuous movement of rotation and extending between two plates which support oscillating shafts equipped with rocking levers kinematically connected to the series of knives. The input shaft is equipped, in the vicinity of each plate, with means for driving the rocking levers. The oscillating shafts extend in parallel between the plates and are each connected to the input shaft by a single rod and eccentric link, a link being respectively made in the vicinity of each plate.

Description

technical field [0001] The invention relates to a shedding device and a Jacquard loom equipped with such a device. More specifically, the present invention relates to the antiphase vertical motion of two sets of broaches or blades in a Jacquard loom ensuring the vertical movement of the hooks of a weaving system. In such looms rows of hooks are raised alternately by rods or broaches commonly called "blades" or "neck knives", which are themselves often supported by one of two neck knife holders. Each carriage must be driven by a vertical oscillation in anti-phase to the other carriage. Background technique [0002] For this purpose, it is known in FR-A-2669650 to use an input shaft driven by a continuous rotary motion and on which are mounted four eccentrics each interacting with a link for controlling a rocker, which The rockers are mounted in groups of two on shafts provided on each side of the bracket. The kinematics of this device are complex and costly, and at the sam...
