Definitions

  • This invention is a web winding method and apparatus and, more particularly, is directed to a novel method of and apparatus for continuously distributing gauge bands (i.e., bands of different thickness then general web thickness) in a web laterally throughout such web by oscillating the windup roll during winding of the web thereon and still obtaining even edges on such wound roll as it is wound by reciprocating Web edgeslitters (and web center slitter or other web slitters) in timed relationship with such windup roll.
  • the winding operation is accomplished with no lateral movement of the web with respect to its supply source except after it is wound on the windup roll.
  • US. patent to Davis 2,130,332 discloses a method of winding a web of paper in a manner to prevent the building up of ridges due to superimposed minute irregularities in the thickness of the paper, such as arise from its manufacture on the paper making machine, which irregularities run longitudinally of the web, consisting of continuously oscillating the web laterally in its own plane during the winding or rewinding operation by oscillating the web unwind roll or windup roll in an amount exceedingly minute in comparison with the width of the web, thereby distributing substantially uniformly such longitudinal irregularities over a lateral distance equal to the amplitude of the oscillation.
  • the uneven edges of the wound roll obtained by oscillating the windup roll may be removed by rewinding and trimming.
  • US. Patent 2,946,532 to Carter discloses an oscillator for web winding devices in which the windup roll is oscillated with respect to the web source in a predetermined manner related to the web speed to prevent irregularities, such as thick or thin places from building up.
  • the web winding apparatus of this invention is continuous 1n operation.
  • the apparatus continuously winds a plastic web from a supply source onto a windup roll and includes means for moving the web continuously from the supply source to the windup roll; for slitting the web continuously at least at the edges thereof with web edge slitters as it moves from the supply source to the windup roll; for reciprocaitng the edge slitters continuously relative to the supply source as the edges of the web are slit; and, means for reciprocating the windup roll continuously relative to the supply source and in timed relationship with the slitters as the web is being wound onto the windup roll whereby the only relative motion of the web with respect to the supply source (and to the parts of the apparatus between the supply source and the windup roll) occurs substantially only after the web is wound onto the windup roll thereby to distribute gauge bands in the web laterally throughout the wound web, still obtaining even edges in the wound web as it is wound.
  • a web of plastic film usually has one or more zones of greater or lesser thickness than the rest of the web (i.e., gauge variations) that exist lengthwise or in the machine direction of the web and when the web is wound directly onto a windup roll these continuing zones lie one atop the other as the successive layers are wound thereon so that in cumulative effect a gauge band, either thicker or thinner as compared to normal Web thickness, is built up.
  • Gauge bands i.e., lanes or zones in a web of plastic film which are slightly thicker or thinner than adjacent web areas, usually by more than 10%
  • Gauge bands usually remain in the same transverse location for relatively long periods of time during production of the web, thus they are continuously wound along the same path on the windup roll. This causes the buildup of hard bands on the wound roll and results in stresses which, in time, distort the roll, thereby impairing its utility and causing waste.
  • the web particularly a web of plastic film
  • the web should follow an unerring path of movement relative to the supply source so that there will be no relative movement between the web and the various rolls that support and pull and carry it from the supply source to the windup roll. This is so because such movement, however slight, can easily create wrinkles in the plastic web or jam machine web feed or rub the web surface to scar or rip or deface the thin plastic film and render it virtually useless.
  • the present invention solves these problems and other problems existent in the prior art by osciliating or reciprocating a windup roll and edge (and center) slitters simultaneously to overcome these deficiencies and to form wound film rolls free of built up gauge bands and having smooth ends or edges.
  • the oscillation of gauge bands during web Winding should occur without sliding contact of the web With any roll surface in order to avoid marring the film surface.
  • the present invention achieves this latter goal by oscillating a windup roll or rolls and slitters in synchronism; thus, while the path of the center line of the slit web and the edges of the slit web will movefrom side to side along a given path due to oscillation of the slitters relative to the web and the web supply source, there is no relative movement of the web with respect to the web supply source or to other rolls, including the windup roll. Uniform winding is achieved by oscillating the windup roll so as to follow the path of the edges of the web.
  • Slitting in a free span of film in which the slitters are free to move transversely relative to the web is still another advantage of this invention.
  • a tension idler roll is positioned adjacent the slitters to provide necessary tension and prevent billowing of the web during slitting, as will be further explained.
  • FIG. 1 is a perspective diagrammatic view of the web winding apparatus of this invention, with parts omitted for clarity, showing a web as it moves from a supply source past web edge slitters and center slitter and onto windup rolls, the slitters and windup rolls being operable to reciprocate in timed relationship to each other and to the supply source, and
  • FIG. 2 is a plan view showing, in exaggerated form and with parts omitted for clarity, the supply source, the web, the web edge slitters and center slitters and the windup rolls of the winding apparatus of FIG. 1 and further showing the slitters and windup rolls in their extreme positions of reciprocation relative the supply source and the relative positions of the web with other parts of the apparatus during the web slitting and web winding operations.
  • a web 10 of plastic film to be wound by the web windingapparatus of this invention is supplied from a supply source 11, such as supply roll 12, and moved past and into operative association with a web slitter means 13 and, after slitting, wound onto web windup rolls 14 and 15, in a manner to be described.
  • the supply source 11 may be any appropriate source other than a supply roll; the web 10, for example, may be a web of plastic film as it emerges from the tenter frame of a polyethylene terephthalate film production line.
  • the web 10 passes under an idler roll 16 and over a transfer roll 17 positioned between the supply source 11 and the windup rolls 14 and -15.
  • This idler roll 20 provides tension for the web 10 in the free span and prevents billowing of the web upon contact with the slitters.
  • the web 10 is slit by the center slitter 19 into two webs, 21 and 22, and the edges 102 of the web 10 are trimmed by the edge slitters 18 of the slitter means 13.
  • the edge trim 23 cut from the web 10 by the slitters 18 is conveyed around the support roll 17 to trim removal chutes 24 (only one chute is shown) from which it may be fed to a chopper. If the chopper is employed to shred trim waste, it is desirable to isolate chopper jerk from the web handling apparatus; therefore, narrow layon rolls 25 and 26 are employed to engage the edge trim 23 on the roll 17.
  • the webs 21 and 22 are moved separately to the windup rolls 14 and 15.
  • these windup rolls are positioned apart so that web 21 goes directly from the transfer roll 17 to the windup roll 14 and web 22 goes over a second transfer roll 26 to the windup roll 15.
  • the windup rolls 14 and 15 are center driven; windup roll 14 being driven by a drive motor 27 and windup roll 15 being driven by a drive motor 28.
  • Auxiliary means may be empioyed to control torque and winding tension.
  • layon rolls of a suitable type may be employed on each windup roll to assist in producing rolls of desired characteristics.
  • the motors 27 and 28 and various other known mechanisms employed in the practice of this invention are shown diagrammatically in the drawing for convenience.
  • the touchstone of the present invention is the improvement of final roll formation on windup rolls 14 and 15 and distribution of gauge bands in the web 10 (and in webs 21 and 22) by transversely oscillating or reciprocating the web slitter means 13 and the web windup rolls 14 and 15 relative to the supply source 11 and in timed relationship to each other.
  • the average width of the edge trim 23 will be slightiy greater than that normally removed for bead trim on film produced with edge beads for gripping by transverse stretching apparatus.
  • the total additional width of trim 23 is equal to the amplitude of the oscillation, which can be as high as 12 inches for severe gauge band problems, but generally is about 6 inches. Oscillation is usually at a rate of about 3 inches per 'minute or less.
  • the web slitter means 13 is reciprocated by means of a reversible A1 H.P. DC electric motor 29 through a rack and pinion in a slitter means oscillator or drive 30.
  • Windup rolls 14 and 15 are mounted on turrets 31 and 32, respectively (these are usually each adapted for three rolls for rapid starting of new windup rolls, but are shown as single rolls here for simplicity).
  • the turrets are equipped to move on rollers in a direction transverse to the direction of web travel.
  • Turrets 31 and 32 are reciprocated relative to the supply source 11 by reversing synchronous motors 33 and 34, respectively, which are reversed by actuation of limit switches in the slitter means drive 30, through circuit means 37.
  • synchronous motors are reversible and are coupled to mechanical traversing systems 38 and 39, such as a margin control on a Cline winder (made by Eagan Company), as is known in the art. Again, the motors, the traversing systems, and various other known parts of the apparatus are shown diagrammatically in the drawing for convenience.
  • FIG. 2 shows in exaggerated dimensions, the two extreme positions of reciprocation of the web slitter means 13 and the windup rolls 14 and 15 relative to the supply source 11 and the relationship of these parts with respect to the web at such positions.
  • Various parts, such as the transfer roll 17, have been omitted from this showing for clarity and for a better understanding of the invention.
  • the windup rolls 14 and 15 are adapted to receive the webs 21 and (22 in a straight line from the slitter means 13 to form or obtain smooth ends or edges in the rolls wound onto the windup rolls 14 and 15.
  • the web slitter means 13 and the windup rolls 14 and ⁇ 15 are then reciprocated to their extreme righthand posi tions, as shown in FIG. 2, and, thus positioned, they slit the :web 10 along lines 40, 41' and 42 (shown as dotted lines).
  • the windup rolls 14 and 15 again are adapted to receive the webs 21 and 22 in a straight line from the slitting means 13 thereby to obtain smooth edges on the wound rolls in these positions during winding and in all positions between the extreme lefthand and righthand positions.
  • the speed of the web 10 and the speed of the traversing motion of the slitter means 13 is such that the maximum angle made by the slit with respect to an edge 10a of the web 10 is substantially less than a degree of arc, generally a matter of a few seconds; for example, at typical web speeds at hundreds of feet per minute and normal traversing speeds of less than three inches per minute the angle is negligible.
  • the timed oscillation of the windup rolls 14 and 15 and web slitter means 13 with respect to the supply source 11 prevents any continuing gauge bands that may exist in the web 10 from being repeatedly wound directly one atop the other as the webs 21 and 22 formed from web 10 are wound onto such windup rolls 14 and 15 and still produces even edges in the wound webs as they are wound.
  • the oscillatory movement of the windup rolls 14 and 15 distributes the gauge bands or moves them laterally and prevents the cumulative formation of gauge bands in one area or line or zone of the webs 21 and 22 as the webs are wound onto the windup rolls 14 and 15 and the timed oscillation of the slitter means 13 with such windup rolls obtains in the webs wound onto the windup rolls 14 and 15 the even edges desired and required.
  • both of these goals are obtained by oscillating the slitter means 13 simultaneously with the windup rolls 14 and 15 relative to the supply source 11 and to the web 10.
  • the reciprocation of the web slitter means 13 in a direction at right angles to the movement of the web 10 defines the edges 21e along web 21 and the edges 22 along web 22. Due to the constant oscillation of the slitters 18 and 19 defining these edges, such edges assume or define a truncated sawtooth path which would wind in a crooked or uneven fashion if wound onto a stationary windup roll. Applicant avoids this uneven winding by oscillating the windup rolls 14 and 15 in timed relationship with the oscillation of the slitter means 13 and thereby assures that the edges 21a and 22e of the webs 21 and '22 will always wind in a straight line or fashion onto the windup rolls 14 and 15.
  • the web slitter means 13 is oscillated relative to the web 10, there is no move ment of the web 10 or the webs 21 and 22 with respect to the supply source 11 during slitting or during the entire movement of the web or webs from the supply source 11 to the windup rolls 14 and 15. Hence, damage to the web or webs during travel is minimized.
  • a reversible fluid cylinder can effectively be used, as well as oscillation of the rolls with a margin adjustment device, such as a Fife or an Askania edger, on the windup roll.
  • a margin adjustment device such as a Fife or an Askania edger
  • a single web may be wound onto a single windup roll or more than two rolls may be wound onto windup rolls, still following the teachings of this invention.
  • the foregoing description relates primarily to a web winding apparatus for use with a web of plastic film coming from a production line, such as from a tenter frame employed in biaxial orientation of a film, such as polyethylene terephthalate.
  • a production line such as from a tenter frame employed in biaxial orientation of a film, such as polyethylene terephthalate.
  • Such fim is conventionally slit substantially near its center line and at the web edges, including the beads at such edges for gripping by tenter clips, are trimmed at the same time.
  • the edge and center slitters, as described oscillate or reciprocate in unison and take a variable trim from each edge, causing the center slit to move in a wavelike locus in conformity to the slit edges of the web to yield two sheets of substantially equal width having substantially parallel edges.
