Embodiment Construction

[0028] figure 1 A jacquard mechanism 2 is shown, sometimes called a jacquard machine, enabling the formation on a loom of the sheds of the warp threads applied to the woven fabric. The Jacquard mechanism 2 includes a main input shaft (not shown) and a mechanism 6 that transmits motion between the input shaft and a series of blades or knives 12 . The mechanism 6 consists of two coaxial shafts 4, between which only the hollow outer shaft figure 1 visible in . Each of the shafts 4 is driven in an alternating rotational movement about a longitudinal axis X4, which is horizontal during operation. The mechanism 6 also includes a lever, a ramp and a connecting rod 8 actuated by the rotation of the shaft 4 . The mechanism 6 forms a kinematic chain, and the rotation of the input shaft can realize the movement of the blade 12 through vertical alternating motion in opposite phases. Thus, during operation, when blade 12 is in the high position, the two adjacent blades are in the low p...

Abstract

The invention relates to a blade (12) for moving hooks of a Jacquard mechanism for forming a shed on a Jacquard loom. This blade comprises at least one profile (14) made from a composite material, having a body made up of unidirectional fibers that extend in the longitudinal direction (X12) of the profile and are embedded in a resin.

Description

technical field [0001] The invention relates to a blade for moving hooks of a jacquard mechanism and a jacquard mechanism comprising the blade. Background technique [0002] In a known manner, a jacquard mechanism or jacquard machine is a device for forming sheds on a jacquard loom comprising a series of blades or knives driven by alternating vertical movements in antiphase, that is, when one blade is in a high position , with its two adjacent blades in a low position. Numerous hooks arranged in rows can be fitted with each blade. The hooks of adjacent two blades are connected in pairs by ropes. The movement of the hook is controlled by the movement of the blade and by a system such as an electromagnetic system for selectively securing the hook. A system of pulleys makes it possible to transmit the movement from each set of hooks to the heddles traversed by the warp threads. This then makes it possible to create sheds for the passage of the weft threads. The jacquard bl...
