Definitions

  • this invention relates to a take-up mechanism for a loom for weaving fabric comprising a positively driven take [56] References and up roll and at least one support roll which together UNITED STATES PATENTS cooperatively form at least one press nip and exert a positive resultant force on the fabric as it passes 1,649,080 11/1927 Ross ..139/307 through the press nip 2,070,147 2/1937 Thompson ..l39/308 X 2,672,163 3/1954 Walters ..l39/307 X 11 Claims, 1 Drawing Figure PATENTEDUCT 11 I972 3.698.446
  • High tension weaving for example, weaving at warp tensions of about 30 to 60 pounds per lineal inch of width, is of particular concern to manufacturers of papermakers fabrics in that due to the high degree of uniformity in weave pattern which is required by papermakers in order to be assured of the production of an acceptable paper or similar products, the high warp tension in thefabric must be maintained substantially uniform during the entire weaving process since, if it is not, some of the warp yarns may be more slack than the others, thereby causing pick variations. Looms heretofore used for high tension weaving are not readily adapted for maintaining the predetermined warp tension substantially uniform.
  • the present invention provides an uncomplieated apparatus for maintaining even low warp tensions substantially uniform.
  • Another object of this invention is to provide a loom take-up mechanism which will maintain the warp tension substantially uniform during high tension weaving.
  • Still another object of this invention is to provide a loom take-up mechanism which does not require the use of complicated apparatus.
  • a further object of the present invention is to provide a take-up mechanism which requires relatively simple modifications of existing looms.
  • FIG. 1 is a perspective view of the preferred embodimentof the present invention.
  • a take-up mechanism Z which comprises a support means 4, for
  • the frame of the loom having affixed thereto a fabric support member 6, and having rotatably mounted thereto by means of axles 8, l0, rearward cradle roll 12 and forward cradle roll 14.
  • Cradle rolls 12, 14 are in supporting relationship to solid lower take-up roll 16.
  • Axle 18 extends into an opening 21 in support means 4 such that roll 16 can move vertically and/or horizontally, as described in more detail hereinafter,
  • Fabric support member 6 comprises a fabric guiding member 19, which is affixed tosupport means 4, and upper take-up roll 20, which is rotatably mounted to support means 4 1 by means of axle 22.
  • Upper take-up roll 20 is caused to rotate by means of sprocket 24, which is affixed to axle 22, and chain 26 which engages sprocket 24 and the driving mechanism of the loom (not shown).
  • Lower take-up roll 16 is caused to rotate at the same speed as upper take-up roll 20, by means of an interconnecting linkage comprising, for example, gear 28, which is affixed to axle l8, and gear 30, which is affixed to axle 22.
  • the woven fabric 34 passes over the fabric guiding member 19, partially wraps around upper take-up roll20, engages lower take-up roll 16 and passes through the press nips which are formed by lower take-up roll 16, and cradle rolls l2 and 14, respectively.
  • the fabric 34 is subsequently wound for storage.
  • the cradle rolls l2, 14 are disposed relative to one another so as to impede any tendency for the lower take-up roll 16 to fall from the cradle.” For example,
  • the axle 10 of cradle roll 14 is The diameter of the take-up rollls 16, 20 and cradle I rolls 12, 14 relative to each other is not critical, except that the outer diameter of the take-up roll 16 should be greater than the distance between the closest part of A the cylindrical surfaces of cradle rolls 12, 14 so that the latter will support the former.
  • All of the rollsextend horizontally in the transverse direction that is, their axes extend in a longitudinal plane disposed in a direction substantially at right angles to the direction in which the woven fabric is moving. Generally, the rolls will be placed near the front of the loom.
  • slippage of the take-up mechanism 2 may be substantially eliminated, and the warp tension in the fabric 34 may be maintained substantially uniform, as a result of the positive resultant force by which is meant the effective force exerted on the fabric 34 as it passes through the press nips formed by lower take-up roll 16,
  • This force may be made to increase as the warp tension in fabric 34 is increased, so that the pressure exerted on the fabric by the press nips formed by take-up-roll 16, and cradle rolls 12, 14 will be increased, such that the increased warp tension will be maintained substantially uniform and the lower take-up roll will continuously drive the fabric through the take-up mechanism 2 during the weaving process.
  • the positive resultant force has two vector components; that is, the force resulting from the weight of the lower take-up roll bearing against at least one support or cradle roll, and the force resulting from the lateral moment of force produced by the lateral movement of roll 16 induced by tension on the fabric 34.
  • the positive resultant force may be varied by varying either or both of these vector components.
  • the nip pressure may be increased as warp tension increases; that is, the positive resultant force may be increased on fabric 34 during the weaving process, by warp tension increases causing the lateral moment of force to increase.
  • this is achieved by causing fabric 34 to wrap around more than 180 of roll 16.
  • warp tensions of about 45 pounds per lineal inch of width may be maintained substantially uniform by using a solid steel lower take-up roll having a diameter of 8 inches, the weight being distributed throughout the roll at about 14 pounds per lineal inch of width, and causing the fabric to wrap around the lower take-up roll more than 180.
  • Fabric 34 may be guided in such a manner as to wrap lower take-up roll 16 the desired amount, by means of a breast beam which extends in the transverse direction and is affixed to support means 4.
  • the woven fabric passes over and partially wraps around the breast beam, engages the lower take-up roll, passes through the press nips formed by the lower take-up roll and cradle rolls, and is subsequently wound up.
  • a fabric guiding member 19 and upper take-up roll 20 are used in place of a breast beam. In this manner, fabric abrasion is substantially reduced.
  • the lower talre-up roll may cooperatively form press nips with any number of support rolls, the cooperative relationship being perfected by a lower take-up roll and one support roll.
  • take-up rolls 16, 20 be identical. This may be achieved by causing lower take-up roll 16 to be driven by upper take-up roll 20 by means of gears 28, 30. It should be noted, however, that the exact means for maintaining the speeds of the take-up rolls 16, 20 identical is not limited to such a construction and any well-known means may be used. For example, take-up rolls' 16, 20 may be independently driven by the loom and/or some auxiliary driving means.-
  • cradle rolls 12, 14 may be driven by some driving means, in the preferred embodiment they are caused to rotate by the movement of the fabric 34 through the press nips formed by the lower take-up roll 16 and cradle rolls 12, 14, and by the driving motion of lower take-up roll 16.
  • the gripping action of the rolls upon the fabric may be increased by providing all or some of them with a surface having a high coefficient of friction.
  • all of the rolls have a rubber covering 36 adhesively bonded thereto.
  • a take-up mechanism for a loom for weaving fabric comprising a take-up roll
  • the axes of said rolls being substantially parallel to each other and extending substantially at right angles to the path traveled by said fabric as it is woven in said loom, said rolls cooperatively forming at least one press nip, said take-up roll being free to move vertically and/or horizontally relative to the axis of said support roll so that when said fabric so traverses the surface of said take-up roll that increasing tension on said fabric will impel the axis of said take-up roll closer to the axis of said support roll, the force exerted on said fabric passing through said nip will be increased.
  • a take-up mechanism for a loom for weaving fabric comprising a take-up roll
  • first and second support roll spaced apart by a distance between the closest part of their cylindrical surfaces which is less than the outer diameter portion of said fabric passing sequentially through of said take-up roll, said first press nip and then through said second and means for imparting torque motion to said takepress nip,
