Embodiment Construction

[0033] The weaving machine M partially shown in the figures is equipped with a shedding device 10 having two sets of gibs or blades. The first set of lifting knives 12 is supported by two cross members 14 and 16 which are connected together by spacers (not shown) and thus form the first blade holder for the lifting knives 12 . The second set of lifting knives 22 is supported by two cross members 24 and 26 forming a second blade holder. Cross members 14 and 16 are disposed above cross members 24 and 26 respectively at the ends of lift knives 12 and 22 . Lifting knives 12 extend generally at the bottom of cross members 14 and 16, while lifting knives 22 extend generally at the top of cross members 24 and 26, such that lifting knives 12 and 22 can be interleaved with each other. Lifting knives 12 and 22 are rigidly mounted on cross members 14 , 16 , 24 and 26 . In particular, there are no connecting links between the lift knives 12 and 22 and the cross members 14 , 16 , 24 and ...

Abstract

The invention provides a device for forming a shed on a Jacquard loom; two knife boxes (C1) provide a reciprocated vertical actuation to two set of knives; each knife box is driven by means of a reciprocated motion (F1) by at least two rods (102, 112); the at least two rods (102, 112) are hinged on a rocker arm (82) driven by a shaft. At least a knife box is assembled with a guiding system for guiding the knife box to do reciprocated movement; the guiding system comprises a rocker (202) hinged with the knife box relative to a first axis (X1). The guiding system is independent to the driving rod, and further comprises a first arm (204) and a second arm (206); the first arm (204) and the second arm (206) are respectively hinged with the rocker (202) relative to a second axis (X2) and a third axis (X3) on two sides of the first axis (X1). The first arm (204) is hinged on a fixing part of the device relative to a fifth axis (X5). The fourth axis (X4) and the fifth axis (X5) are located on two sides of a vertical straight line (delta 1) crossed with the first axis (X1). The axes are parallel.

Description

technical field [0001] The present invention relates to a shed forming device on a jacquard type loom, and a jacquard type loom equipped with such a device. [0002] More specifically, the invention relates to vertically actuating in opposite phase two sets of gibs or blades used in Jacquard type looms to transmit vertical motion to hooks forming part of the weaving mechanism. In this type of loom, the hooks are arranged in rows and they are lifted alternately by said blades or griffes - also called "griffes" - each of which is itself supported by two One or the other of the cartridge supports. Each cartridge needs to be driven by vertical reciprocating motion in opposite phase to the other cartridge. Background technique [0003] For this purpose, it is known from FR-A-2 669 650 to use an input shaft driven by a continuous rotary movement and on which are mounted four eccentrics, each associated with a lever for controlling a rocker arm. The blade holder is suspended by ...
