Embodiment Construction

[0020] The basic construction of a Jacquard loom is sufficiently known that only a brief overview will be given below. figure 1 The weaving equipment shown in basically comprises parts known per se: Jacquard loom 1, harness 2 and loom 3, which are only schematically shown in figure 1 middle. In particular, only the associated carabiners 4 and 5 , which are connected to one another via a first looper 6 , are shown for the Jacquard machine provided with reference 1 . The looper 6, such as figure 1 , shown only schematically, extends via the pulley block part 20 according to the invention. on the contrary, figure 1 Not shown is the control device of the jacquard machine 1 , by means of which the lifting and lowering of the carabiners 4 and 5 is carried out and their controlled support in an upper position or a lower position is also ensured. Devices which can realize this are likewise sufficiently known from the prior art. Reference is made in this regard in particular t...

Abstract

The invention relates to a tractive pulley element (20) for use in a Jacquard machine (1). Said element comprises at least one first rope pulley (25) for guiding a first slip-knot (6) and at least one second rope pulley (30) for guiding a second slip-knot (8), one of the two slip-knots (6, 8) being connected to at least one lifter (4, 5) of a Jacquard machine (1) and the other slip-knot (8) beingconnected to at least one harness cord (10) for lifting a warp thread (14). The first and second rope pulleys (25, 30) can rotate independently of one another. The tractive pulley element (20) comprises a bearing (21) that consists of an inner ring (22) and an outer ring (23). The inner ring (22) and outer ring (23) of the bearing (21) can rotate independently of one another and one of the two rope pulleys (25, 30) is connected to the inner ring (22) and the other rope pulley (25, 30) is connected to the outer ring (23) of the bearing (21).

Description

technical field [0001] The invention relates to a pulley block component used in a jacquard machine. Background technique [0002] In order to produce the so-called double-acting full-open shed operation (Doppelhub-Offenfach-Arbeitsweise) of the Jacquard machine, a so-called block and pulley system is preferably used, as is known from EP 0 287 921 A1 of the applicant. In this known system, two half carabiners work on a first pulley of a pulley block via a flexible heald (so-called looper), so as to produce two possible positions of the fully open shed ( One of the Offenfachstellungen). In this device, the stroke of the pulley is reduced to half the stroke of the carabiner. Utilizing a second pulley disposed in the block housing in fixed relation to the first pulley and a second looper including a fixed and a loose end, the initial pulley is regenerated on the loose looper end. hook stroke. The looper ends controlled in this way are then connected in their position to at...
