1. A loom comprising:
- a subassembly including heddles, a beater, and inserter means for inserting weft into the shed formed by warp yarns;
a shed-forming device;
first lubrication means for lubricating certain components of the subassembly, the first lubrication means including a first circuit for circulating a first lubricant; and
second lubrication means for lubricating the shed-forming device, the second lubrication means including a second circuit for circulating a second lubricant;
a heat exchanger system for exchanging heat between the first lubricant and the second lubricant without fluid communication between one another, and wherein the heat exchanger system includes circulation means for circulating a lubricant selected from the first and second lubricants and a coolant fluid to a heat exchange zone where the lubricant or the coolant fluid is in heat exchange relationship with another lubricant selected from the first and second lubricants such that the first lubricant is used as a heat exchange agent for the second lubricant.

Abstract
A loom having a subassembly including heddles, a beater, and a device for inserting weft into a shed formed by warp yarns and also including a shed-forming device and a lubrication system for lubricating certain components of the subassembly including a first circuit for circulating a first lubricant and a second circuit for circulating a second lubricant for lubricating the shed forming device. The loom includes a heat exchanger system for exchanging heat between the first lubricant and the second lubricant without fluid communication between the lubricants.

10. A method of controlling temperature of a lubricant in a shed-forming device of a loom, wherein the method includes the steps of putting the lubricant into leaktight heat exchange relationship with another lubricant used for lubricating components of a subassembly of the loom including heddles, a beater, and inserting means for inserting weft into a shed formed by warp yarns such that one of the lubricants functions to cool the other lubricant.
