Definitions

  • the present invention relates to a novel loom arrangement, more particularly for looms wherein the weft threads are introduced by means of la plurality of shuttles moving in traversing sheds which are arranged in column fashion.
  • the invention provides a novel arrangement of the loom elements, producing thereby a loom which is easy to build, to operate and to maintain, as will be explained hereunder in full detail.
  • the formation of the sheds is accomplished in the region of this vertical path section, the healds reciprocating approximately in a horizontal direction.
  • Beating up is performed by vertical reciprocation of the reed; the cloth which is prepared passes over a sand roller in vertical, downward direction and is eventually wound on a cloth beam arranged in the lower machine frame porti-on.
  • Such looms have various drawbacks, of which the most prominent is that the loom operator cannot readily supervise the formation of the cloth and inspect the cloth or fabric which has been formed, since it is being ,formed and wound in a lower region of the loom which is difiicult to reach yand not easy to survey. Breakage of warp threads may not be readily repaired by the operator since the warp-threads are taken off at the rear yof the loom. The operator has to alternate between the front and rear sides of the loom for repairing any broken warp threads.
  • Another disadvantage is that a loom having the warp beam arranged on the top is so high that the operator is unable to supervise looms arranged behind the loom in front of him.
  • the object of the present invention to eliminate the above-mentioned and other drawbacks of hitherto known looms.
  • the invention has for one of its major objects to provide a novel loom arrangement which makes forsimple construction, easy operation and maintenance.
  • ⁇ a loom arrangement wherein the Warp beam is located in a lower machine frame port-ion, preferably in its center line, the warp threads being guided therefrom in upwardly, substantially vertical direction.
  • the clot-h beam is provided in an upper machine frame portion, and may be displaced somewhat rearwardly yfrom the Warp beam thereunder.
  • the traversing sheds lhaving a pluralityv of shuttles are formed within a somewhat inclined, substantially vertical path section of the warp threads, from where the manufactured cloth is guided over a sand roller and thence to the topmounted cloth beam.
  • a still further feature of the invention provides one or more guide rollers or shafts -along the warp-threaded path wherever a change in direction is required, e.g. from horizontal to vertical, at the lowermost section of the path, or from vertical to horizontal, before the warp threads pass underneath the stop-motion mechanism.
  • a machine frame 2 includes a lower portion 2a and an upper portion 2b. Centrally journaled in the former is a warp beam 4 for threads 30, which is freely accessible from the rear of the loom.
  • the upper frame portion carries a cloth beam 6 ⁇ for cloth 40, preferably somewhat real-wards from the warp-beam taxis.
  • the Warp threads 30 are guided from the warp beam 4 to a guide roller 8 rotatably supported in a bottom frontal region of the lower frame portion 2a. From here the threads 30 pass in a substantially vertical, upward direction toward a second guide roller 18, after which the warp-thread path becomes almost horizontal towards the rear. This path section is well visible to the operator and has thereabove a plurality of conventional Warp stop-motion elements, as schematically shown at 10.
  • the relatively short horizontal path section ends at a further guide roller or shaft 28. From here, the threads pass upward at an angle, in approximately vertical direction, toward a sand roller 12 journaled on the front side of the upper frame portion 2b.
  • the aforementioned cloth beam 6 is mounted to the rear from the sand roller 12.
  • the weft threads applied by each of the shuttles 14 are beaten up by reed blades (not illustrated) which protrude between the warp threads.
  • the conventional weaving mechanism referred to hereinabove may be designed and operated, e.g. as has been referred to in applicants co-pending patent application Ser. No. 239,677, led November 23, 1962, :and entitled Weaving Method and Loom and may, of course, also comprise known means for equalizing or compensating changes in length of the individual warp threads, result-v ing from the usual shed movements.
  • the shuttles 14 running in column fashion within the traversing sheds substantially -rest on the upwardly acting reed blades or dents so that the shuttles run smoothly and without special supports Iand without risk of interference with the warp threads.
  • the beaten up cloth or fabric 40 moves toward the sand roller 12 and thence to the cloth beam 6, as mentioned before.
  • the lower frame portion 2a may carry appropriate bobbin holders 16 for the weft-thread bobbins.
  • a drive means for operating the shuttles 14 and for supplying the latter with weft threads may be provided on the upper frame portion 2b; this mechanism is schematically shown at 20.
  • the entire mechanism can be made relatively light-Weight necessitating but a small oor area, since there is no heavy weight to be carried on top of the structure. It is known that the cloth beam takes up less space than the warp beam. Furthermore, the finished fabric may be removed from the rear side of the loom from time to time in the form of individual rolls if a cut of commercial size is iinished.
  • any disturbance like a thread breakage, can immediately be eliminated by repairing the broken thread and threading the warp thread through the warp-thread stop motion mechanism from the front of the loom.
  • the formation of the fabric can be readily supervised and the cloth formed on the loom and running upwardly from the region where the fabric is formed can be readily inspected.
  • the loom according tothe invention is of a height less than the eye level of an operator of average size even if the biggest known warp beam is used.
  • the operator is capable f supervising further looms arranged not only in the same row but'also behind the loom in front of him.
  • Each of the traversing f shed elements includes a shuttle 14 to which is imparted is basically taken up by the reed dents, so that the former move safely and without difficulty, allowing thus higher speeds and better products to be achieved.
  • a loom comprising, in combination, a machine frame including a lower and an upper frame portion, a warp beam journaled approximately in the gravita- ⁇ tional center of said lower frame portion, a cloth beam journaled Iin said upper frame portion, means for guiding warp threads from said warp beam toward said cloth beam, said guiding means including a first guide roller located at the front and bottom of said lower frame portion for directing said threads away from said warp beam toward an extreme front portion of the loom, a
  • said guide means including a third guide rolle-r transversely spaced from said second guide roller, said second and said third guide rollers acting to change the direction of said threads from said vertical direction to a relatively short horizontal section in which the Warp threads move in a rearwardv direction, weaving means located above the region of said horizontal section, said third guide roller further acting in combination with a sand roller to guide said threads into a ⁇ further substantially vertical plane through said weaving means, the warp threads on said horizontal and on said further vertical section being freely accessible.
