Definitions

  • This invention relates to a weaving machine for making terry cloth.
  • Weaving machines for making terry cloth that is, cloth having loops formed from a pile warp on one or both sides, have usually formed the loops during weaving by suitably controlling the blow of the reed or by superimposing a reciprocating cloth motion on the normal taking up of the cloth.
  • weaving machines which use corundum-coated drawoff rollers instead of porcupine rollers, it has been found that such machines often suffer from an undesirable phenomenon, particularly if dressed yarn which forms relatively hard loops is used for the pile warp. That is, the cloth formed does not run onto the cloth draw-off roller straight, but creeps to one side or the other while being taken up. This has caused creasing of the cloth and makes it difficult or impossible to wind the cloth satisfactorily on to the cloth beam.
  • the invention provides a means for tumingdown or flattening the loops of a formed terry cloth between the fell area and the cloth draw-off roller, at least on the side of the cloth which faces the cloth draw-off roller, in a direction and to an extent sufficient to prevent lateral creeping on the draw-off roller.
  • the invention is based onthe surprising realization that lateral creep of the cloth web,as the web runs on to the draw-off roller, can be produced intentionally by turning down or flattening the pile loops in a particular direction relative to the direction of the warp. That is, the cloth can be made to creep either to one side or the other, depending on the direction in which the loops are turned down.
  • the means used to tum-down or flatten the loops is such as to turn the pile loops down in a predetermined direction relative to the warps, i.e. not necessarily parallel to the warps.
  • the turning-down or flattening means is provided with a drive which imparts a working movement thereto rela tive to the cloth web.
  • the means for turning-down or flattening the loops is brush-like, more particularly in the form of a rotatable brush.
  • the means may be strip-like, in which case the means may be reciprocated in the direction of the cloth, possibly with an additional motion component transverse to the cloth.
  • the turning-down means is in the form of a roller which, in a weaving machine having a breast beam which is reciprocated in order to form the loops, bears on the breast beam and on a pinch roller associated with the cloth draw-off roller with its axis parallel to the breast beam and pinch roller.
  • FIG. 1 diagrammatically illustrates a weaving machine for terry cloth utilizing a turning-down means situated between the fell area and the breast beam in accordance with the invention
  • FIG. 2 illustrates the manner in which a cloth can creep across a draw-off roller in a weaving machine in the absence of a turning-down means of the invention
  • FIG. 3 illustrates a side view of a rail rigidly connected to a breast beam for turning-down or flattening pile loops in accordance with the invention
  • FIG. 4 illustrates a side view of a loop turning-down or flattening means according to the invention in roll form.
  • FIG. 5 shows a driving device for reciprocating the turning-down means with an additional motion component transverse to the cloth web.
  • the terry cloth weaving machine utilizes a ground warp l1 which runs'otf a ground warp beam 12 and passes through a row of warp stop motion droppers l3, heald shafts 14 used for shedding, and a reed 15.
  • the shed is open.
  • a weft is picked by'a shuttle 16.
  • pile loops 21 are formed from a pile warp 18, which runs off a pile warp beam 17 and passes through another row of stop motion droppers l9, heald shafts 20 and the reed 15.
  • the pile loops 21 are formed by means of a reciprocating motion superimposed on the normal take-up motion of the cloth 22 and produced by means of a periodically reciprocating breast beam 23.
  • the breast beam 23 or 35 has a drive (as shown in FIG. 4) which can transfer the beam 23 over a distance h from a limit position as illustrated into a position 23' or 35' respectively as shown by chain lines.
  • the reed 15 is driven to be moved into the position 15 indicating the fell area after every pick.
  • the cloth 22 runs onto a cloth draw-off roller 24, which is driven in a known manner at a speed corresponding to the formation of the cloth. From the cloth draw-off roller 24, the cloth runs over a pinch roller 25 and is wound onto a cloth beam 26.
  • the terry cloth 22 with the loops 21 would tend to creep to one side (as shown by the position of the selvedge 27) during taking up under the influence of the loops which, as they run onto the cloth draw-off roller 24, would be turned down in a direction such as to promote creep.
  • a turning-down means in the form of a brush 28 is provided between the fell area, indicated by reed position 15', and the breast beam 23.
  • the brush 28 may be stationary, in which case the loops 21 passing beneath the brush 28 are turned back towards the shed.
  • the brush 28 may be driven, particularly if experience shows that the cloth cannot be prevented from creeping sideways along the draw-off roller unless the loops are turned down in the opposite direction.
  • the brush 28 is provided with a suitable driving means (as described later) which causes the brush 28 to rotate in the direction of arrow 29.
  • the brush 28 extends over the entire width of the cloth 22 with the longitudinal axis thereof transverse to the warps. If it is found that the loops must be turned down in a direction obliquely of the warps to prevent lateral creeping of the cloth along the draw-off roller 27, the brush 28 or other turning-down means may extend over the cloth width obliquely relative to the warps.
  • the turning-down means can be in the form of a strip or rail 31 fixed to the breast beam 32 and mounted over the machine to press against the cloth.
  • the pile loops 33 are turned down or flattened towards the shedv
  • the pile loops 34 can also be turned down or flattened by a roller 36 which bears on the pinch roller 25 and breast beam 35.
  • This roller 36 is shown with its axis parallel to the pinch roller 25 and breast beam 35.
  • the invention is not restricted to the embodiments illustrated. For example, it is not always necessary to turn all the pile loops down in the same direction in order to ensure that the cloth web runs straight. In many cases, moreover, it is enough to flatten the loops rather than to turn them down in one direction only. Also, the invention is not restricted with regards to the manner in which the loops are formed as the invention can also be applied to terry weaving machines in which the loops are formed by means of a specially controlled reed motion.
  • FIG. 1 shows a brush roller 28, rotated by means of a sprocket wheel 41 and a chain 42, and supported by a two-arm lever 44 which in turn is oscillated lengthwise, relative to the cloth web, by means of a cam drive 43 and a spring 45.
  • the breast beam 35 in FIG. 4, could be reciprocated in a direction parallel to the warp threads by means of a cam drive 37 and a rod 38.
  • the turning down means which might be a strip or rail 51, bears a prong 52 engaged in an elliptical groove 53 on the surface of a rotatable cylindrical roller 54, which imparts to said strip a longitudinal reciprocating motion, i.e. transverse to the cloth web 55.
  • a terry cloth weaving machine for making a terry cloth with pile loops and having a fell, a cloth draw-off roller downstream of said fell and a cloth beam downstream of said draw-off roller; a brush positioned between said fell and said draw-off roller and disposed relative to the cloth to turn down I the pile loops in a predetermined direction relative to the warp in the cloth at least on the side of the cloth facing said draw-off roller.
  • a cloth draw-off roller downstream of said fell and a cloth beam downstream of said draw-off roller; means positioned between said fell and said draw-ofl roller and disposed relative to the cloth to turn down the pile loops in a predetermined direction relative to the warp in the cloth at least on the side of the cloth facing said draw-off roller, said means including a drive for moving said means relative to the cloth.
  • a terry cloth weaving machine for making a terry cloth with pile loops and having a fell, a cloth draw-ofi roller downstream of said fell and a cloth beam downstream of said draw-off roller; a rail extending across the machine between said fell and said draw-off roller and disposed relative to the cloth to turn down the pile loops in a predetermined direction relative to the warp in the cloth at least on the side of the cloth facing said draw-off roller and a drive for reciprocating said rod in the direction of cloth advance.
  • a reciprocally mounted breast beam for forming the loops, a cloth draw-off roller downstream of said breast beam, a pinch roller adjacent to and parallel to said draw-ofl roller, and a cloth beam downstream of said draw-ofi' roller; a roller bearing on said breast beam and said pinch roller in parallel relation to said pinch roller to turn down the pile loops of the terry cloth in a predetermined direction relative to the warp in the cloth at least on the side of the cloth facing said draw-off roller.
