The warp threads in a loom are cooled, in order to prevent damage to the warp threads due to heat generation by the contact between the warp threads and loom components. Such contact can generate temperatures of 50.degree. to 80.degree. C. due to thread friction and thread shifting, whereby capillary breaks of the warp threads are caused so that continued weaving becomes impossible. Such heat generation is avoided by cooling the loom components which contact the warp threads. A cooling fluid is circulated through the warp thread contacting components. The cooling fluid may be a liquid or a gas. At least the leasing or fulling mill is cooled in this manner. The cooling is preferably carried out to such an extent that condensation water forms on the surfaces of the cooled components, whereby the condensation water acts as a lubricant for the warp threads.
An apparatus for cooling warp threads in a weaving machine, especially for heavy, woven fabrics such as yacht sailcloths, comprising at least one hollow loom component for contacting a warp thread in said weaving machine, and means for circulating a cooling fluid through said warp thread contacting hollow loom component, said cooling fluid cooling said hollow loom component to such an extent that atmospheric moisture condenses on said hollow loom component as condensation water which cools and lubricates said warp thread.
A method for preventing capillary breaking of warp threads in a weaving machine comprising the following steps:
