Problems solved by technology

Furthermore, despite the use of settling devices, hard particles produced in the event of failure of one of the components of the loom or of the shed forming device may contaminate all other components and may significantly shorten the life of the loom

Embodiment Construction

[0020] figure 1 The loom 1 shown comprises a fitting assembly 2 within which warp and weft threads (not shown) are woven. The assembly assembly 2 has a plurality of heald frames 21, and each heald frame 21 is equipped with a plurality of heald pieces 212, for clarity of the accompanying drawings, figure 1 Only a part of the plurality of healds is shown in FIG. 21 , each heald 212 is provided with an eye 214 for passing warp yarns. These heald frames 21 are driven by tie rods 22 which themselves are controlled by reversing rods (not shown).

[0021] The fitting assembly 2 also includes a beater or comb 23 for beating the weft yarns after weaving to compact the cloth. Beater around axis Y 23 Articulation, axis Y 23 perpendicular to as indicated by the double-headed arrow F 1 Indicates the direction in which the heald frame 21 swings vertically. The driving mechanism 24 makes the beater 23 rotate around the axis Y 23 Fore and aft pivot movement.

Abstract

The loom (1) comprises a subassembly (2) including heddles (212), a beater (23), and means (25, 26) for inserting weft into the shed formed by warp yarns. It also includes a shed-forming device (4), means for lubricating certain components (22, 24, 25, 26, 28, 29) of the subassembly, said means including a first circuit (C1) for circulating a first lubricant, and means for lubricating the shed-forming device (4), these means including a second circuit (C2) for circulating a second lubricant. The loom (1) includes a heat exchanger system (6) for exchanging heat between the first lubricant and the second lubricant without fluid communication between the lubricants. The heat exchanger system (6) has means (631, 632, 641, 642, 651, 652) for circulating one of the two lubricants or a coolant fluid to a zone (62) of thermal contact with the other lubricant.

Description

technical field [0001] The invention relates to a weaving machine in which a lubricant, such as lubricating oil, is used, in particular of the type of shed former, cam mechanism or jacquard mechanism of a dobby. Background technique [0002] Modern looms run at high speeds—often faster than 900 picks per minute. The shedding devices associated with such looms require the use of large amounts of mechanical energy, some of which is lost due to friction, thereby generating heat. The heat generated increases the temperature of the lubricating oil used in the loom mechanism to lubricate its moving parts. The lubricating oil heats up to such a temperature that the shed former housing becomes too hot to touch, which is dangerous for nearby operators. This heat also has the effect that the lubricating oil reaches a temperature range to the extent that its viscosity changes significantly, so that the desired thickness of the oil film between two contacting parts is no longer guaran...
