Definitions

  • Cooling systems were proposed in the past to solve the above problems.
  • a further object of the present invention is to provide a loom with assembly provided with a cooling system that is easily adjustable and adaptable to the specific cooling requirements of different weaving conditions.
  • a Jacquard loom has been devised according to the invention provided with thread guide means and with a cooling system of the guide means and of the threads near the guides means, said cooling system comprising:
  • FIG. 1 shows a general view of an embodiment of the cooling system acting on two thread-guide boards in a loom
  • FIG. 2 shows a detail of the cooling system in FIG. 1 .
  • FIG. 1 shows an assembly 11 of a Jacquard loom, that is in itself known and is not therefore shown or disclosed in detail.
  • the assembly 11 comprises a threading board 13 and a loom bottom board 12 for guiding the harnesses or threads 14 in the assembly, according to what is well known in the weaving field.
  • the boards 12 , 13 are provided with a plurality of guide holes 40 , 41 suitable for guiding the threads 14 of the loom according to the prior art.
  • the figure also shows a cooling system 15 set up in the frame to maintain the guide boards 12 , 13 and the threads 14 near the guides at a sufficiently low temperature.
  • the cooling system 15 comprises a blowing fan 17 (for example of the tangential type) actuated by an electric motor 19 .
  • the fan 17 is advantageously provided with an inlet filter 18 to purify the cooling air intended to be blown onto the threads 14 and onto the guide boards 12 , 13 .
  • a supply conduit 20 At the outlet of the air from the blowing fan 17 there is connected a supply conduit 20 .
  • this conduit 20 is an at least partially flexible pipe, in order to enable regulation of and adjustments to the configuration of the cooling system as a whole.
  • two distribution pipes 21 are in fact connected by means of prior-art joint elements; these two distribution pipes 21 are suitable for respectively blowing cooling air onto the threading board 13 and onto the loom bottom board 12 .
  • the pipes 21 are rectilinear cylinders and are advantageously placed along the longest side of the guide boards 12 , 13 (see FIG. 1 ).
  • the distribution pipes 21 are formed of modular segments that can be assembled in series. In this way it is possible to obtain cooling flows of different amounts and such as to adapt as well as possible to the dimensions of the guide boards, thereby preventing waste of cooling air or ineffective cooling of the peripheral zones of the loom.
  • the cooling system that has just been disclosed enables great operating flexibility to be obtained.
  • part of the delivery holes 22 can be closed during use of the loom in such a way as to create a greater cooling flow in those guide zones in which thermal stress is higher and less cooling flow where this stress is less.
  • the air flow is always used to best effect, preventing part thereof flowing where it is not necessary.
  • the disclosed system is also economical in terms of installation costs compared for example with compressed-air systems, costly compression devices not being used.
  • a cooling system has been devised that also enables the thread guide zones and the threads themselves to be kept clean.
  • the blowing air prevents the depositing of foreign bodies or dusts on the guide boards and on the threads.
  • the absence of compressors in the system excludes the possibility of formation of patches of lubricant inside the loom.
  • the distribution pipe and the supply conduit will have a section that is suitable for minimizing load losses of the cooling air flow. It has been found to be favorable to use pipes with a section of more than 110 cm 2 , preferably comprised between 200 cm 2 and 700 cm 2 . Furthermore, in order to create a “pressurized reservoir” effect and to ensure uniform discharge of air from all holes, it has been found to be appropriate to give the delivery holes sections between 0.75 cm 2 and 7 cm 2.
  • the delivery holes of the cooling air need not be equidistant to one another and may have different diameters according their distance from the blowing fan.
  • the distribution pipes could be provided with two open ends and therefore be bilaterally supplied with cooling air rather than unilaterally as disclosed above.
  • the distribution pipes could be provided with two closed ends and be supplied by means of an inlet port arranged halfway along their longitudinal extent.
