Problems solved by technology

As a result, it is impossible for the warp threads controlled by the device to move arbitrarily to one or the other of the two intermediate positions at any time, thus narrowing the weaving options especially for the weaving of loop pile carpets
In addition, the structure of the device does not allow to obtain four equally spaced warp positions, and this becomes an obstacle to the shed opening

Embodiment Construction

[0030] figure 1 The illustrated shedding device 1 comprises four upper movable carabiners 2, 3, 6 and 7 which are vertically movable in pairs by two lifting knives 10 and 11 which are driven to reciprocate in opposite phases. More specifically, the device 1 comprises two load-carrying movable hooks 2 and 3 and two driven movable hooks 6 and 7 connected by a cable 4 forming a cord-like element that goes around a pulley 5 . The driven movable carabiner is connected by a second cable 8 partially wound around a second pulley 9 . With the lugs 2 a and 3 a belonging to the carrying hooks 2 and 3 , the lifting knives 10 and 11 are able to selectively move said hooks 2 and 3 .

[0031] The driven carabiners 6 and 7 simply rest on the carrying carabiners 2 and 3 respectively, which means that the carabiners 2 and 6 can be moved together by the lifting knife 10, just like the carabiners 3 and 7 can be moved together by the lifting knife 11 Same. Thus, carabiners 2 and 6 form a first ...

Abstract

The mechanism has a shed forming device (1) comprising pulleys (5, 9, 15, 16, 17) vertically aligned in middle part of the device. The pulley assembly of a cord (23) is vertically arranged by a hitch comprising a fillet (25) that surrounds a lower pulley (19) integrated in translation from the pulley assembly. One end of the fillet is fixed to a frame of the mechanism, while another end of the fillet is arranged with a lower cutter (31) displacing the lower pulley and cord.

Description

technical field [0001] The present invention relates to a weaving mechanism for determining the warp position of a jacquard type loom and a jacquard type loom equipped with such a weaving mechanism. Background technique [0002] EP-A-0 839 937 discloses a weaving mechanism which enables three warp positions to be obtained by using superimposed carabiners which can be moved vertically in pairs by a lifting knife and which are connected with a set of vertically arranged pulleys Associated. However, a three-position weaving mechanism like this cannot weave certain complex fabrics that require four warp positions, especially in carpet weaving. [0003] EP-A-0 665 312 discloses a four-position weaving mechanism, in which each shedding device comprises four juxtaposed carabiners which can be moved vertically by two lifting knives. The device effectively achieves four evenly spaced warp positions. However, since the four carabiners are arranged side by side, this device takes up...
