Definitions

  • a loom of this type is disclosed in copending application U.S. Ser. No. 758,861, filed Sept. 10, 1968 now US. Pat. No. 3,532,137.
  • the use of an auxiliary beam cooperating with the sand beam permits the cloth to be out between the sand beam and the cloth beam and thereafter the cloth beam to be removed (e.g., when it has been filled completely with the rolled-up cloth) without the need of stopping the loom for this purpose.
  • locking means are used for holding the auxiliary beam in its operative position relative to the sand beam.
  • the present invention provides a weaving loom, comprising a sand beam around which the cloth travels, and at least one auxiliary beam which is arranged adjacent to the sand beam so as to cause the cloth to travel between the sand beam and the auxiliary beam, the improvement consisting in the auxiliary beam being movably supported in such a way that the force exerted on said beam due to the tension in the cloth tends to press the auxiliary beam against the sand beam.
  • each auxiliary beam cooperating with the sand beam is rotatably mounted between two support arms swingably mounted about an axis that is so situated with regard to the sand beam that the auxiliary beam may be swung away from the sand beam so as to provide access to the surfaces of both the sand beam and the auxiliary beam.
  • one auxiliary beam is located at the cloth entrance side of the sand beam and a second auxiliary beam is positioned at the cloth delivery side of the sand beam.
  • auxiliary beam at the cloth delivery side is driven with the intermediary of a slip coupling.
  • the cloth may be severed between said auxiliary beam at the delivery side and the cloth beam and the cloth beam may be removed while the cloth proceeds moving taut against the sand beam.
  • the drawing is a schematic view of part of a loom comprising the sand beam and the associated auxiliary beams.
  • the cloth 1 moves from the weaving shed (not shown) over the breast beam 2 and the sand beam 3 to the cloth beam 4 onto which the cloth is wound.
  • the sand beam 3 is driven by a drive mechanism 5, partly and schematically shown, at a rate which is a function of the weaving speed of the loom.
  • the sand beam 3 has a rough surface to provide reliable friction between the cloth I and the surface of the sand beam 3.
  • the sand beam cooperates with two auxiliary beams 6 and 7.
  • the cloth arriving from the breast beam 2 passes around the auxiliary beam 6 and along the back of the sand beam 3 to the auxiliary beam 7. Thereafter the cloth moves around said auxiliary beam 7 to the cloth beam 4. Thereby the cloth forms a loop la between the auxiliary beams 6 and 7 in which loop the sand beam 3 is located.
  • the loop la of the cloth lies taut around the sand beam 3 and around the auxiliary beams 6 and 7.
  • the cloth is taut around the auxiliary beam 6 because of the tension force on the cloth in the warp direction which is generated by the sand beam 3.
  • the tension in the cloth in the portion between the auxiliary beam 6 and the weaving shed (not shown) is a measure for the quality of the fabric, while the linear speed of the cloth derived from the rotational speed of the sand beam 3 is a measure for the number of wefts per given warp length.
  • the cloth is taut around the auxiliary beam 7 because of the cloth being wound onto the cloth beam 4 and because said cloth beam is driven preferably with an excess in speed i.e., the cloth beam is driven so that the cloth between the auxiliary beam 7 and the cloth beam periphery is always taut.
  • the cloth beam may be driven with the intermediary of a belt 10 guided around pulleys 8 and 9.
  • the belt 10 is allowed to slip in the pulleys 8 and 9 so as to keep the tension in the cloth between the auxiliary beam 7 and the cloth beam periphery at the correct value.
  • the tension in this portion of the cloth is not critical for the fabric quality provided the cloth in the loop la lies taut around the sand beam 3.
  • a separate slip coupling 11 may be applied as a connect ing means between the shaft 12 of the sand beam and the belt pulley 8. The amount of slippage in the slip coupling 11 may be adjusted at will.
  • the auxiliary beam 6 is supported by pivoting arms 13a and 13b, which tend to press the beam 6 against the periphery of the sand beam under the action of the tension in the cloth.
  • the arms 13a, 13b are pivotally mounted on a support shaft 14 located near the breast beam 2.
  • the auxiliary beam 7 is likewise supported by pivoting arms 15a and 15b. In the embodiment shown the pivoting arms 15a, 15b likewise pivot around the support shaft 14 but they may also pivot around a separate shaft.
  • the pivot axis of the pivoting arms 13a, 13b and 15a, 1512 has to be such that a force generated by the tension of the cloth on the auxiliary beams 6 and 7 has a component tending to press the auxiliary beams 6 and 7 against the sand beam 3.
  • auxiliary beams 6 and 7 When a new cloth or mat of warp threads has to be applied around the sand beam 3 the auxiliary beams 6 and 7 may be swung upwardly to provide access to the surfaces of the auxiliary beams 6 and 7 and the surface of the sand beam 3.
  • the auxiliary beams may be locked in their upward position as by means of pawls 16 extending behind cams 17 of the pivoting arms 13a and 150. After disengaging the pawls 16 the respective auxiliary beams may again be brought in their operative positions.
  • auxiliary beams 6 and 7 results in such a good application of the cloth against the periphery of the sand beam 3 that the cloth may be severed between the auxiliary beam 7 and the cloth beam 4, for instance when a full beam has to be removed from the loom, without the necessity of stopping the loom.
  • the cloth hanging down from the auxiliary beam 7 then hangs completely free until a sufficient length is obtained enabling it to be wound on a new empty beam whereafter the new cloth beam is against suspended in its journals in the loom.
  • a weaving loom comprising a driven sand beam having a friction surface for driving engagement with a cloth, woven by the loom, and a driven cloth beam for winding up the cloth leaving the sand beam, wherein the improvement comprises a cloth extending around one auxiliary beam, then around the sand beam, and then around the other auxiliary beam to the cloth beam has a component which presses each auxiliary beam against the sand beam.
