Definitions

  • the present invention relates to strip webbing.
  • High voltage equipment and machinery is often provided with insulation which is made up of thin layers of insulating material which are wound, in layer form, onto the part to be insulated.
  • One edge of the layer generally projects beyond the part and is rent over.
  • a portion of the wound-on insulation which extends beyond the piece being insulated is torn by forcibly rending the strip over so as spatially to deform the insulation, thereby to provide a boundary field insulation.
  • This type of insulation is frequently used for oil-filled high-voltage transformers with layer windings, the insulation having an angledover flange portion which is rent over. While such insulation produces very good boundary field insulation, the same is very expensive, and accordingly, various efforts have been made to reduce the costs of this type of insulation.
  • the insulation is constituted by strip webbing consisting of multiple overlapping transverse insulating strips, which strips are applied onto one or more longitudinal bands at approximately right angles thereto, the purpose of the longitudinal bands being to hold the transverse strips together at least until the webbing is applied to the equipment.
  • the insulating flange which extends at approximately right angles to the axis about which the insulation has been wound is formed by removing the longitudinal bands which are in alignment with that portion of the insulation that extends beyond the winding being insulated, and by then bending the insulation at about right angles to the axis. These flanges can then be retained between rings made of suitable insulating material, such as press board.
  • FIGURES 1 and 2 Insulation of this type is shown, in side and plan views, respectively, in FIGURES 1 and 2, in which the transverse strips 1, 2, 3, arranged in scale-like overlapping relationship, are connected together by means of longitudinal bands 4.
  • FIGURE 2 shows, at 5, 6, 7, those portions of the transverse strips 1, 2, 3, which are visible from above.
  • the longitudinal bands 4 are suitably connected to the transverse strips, such as by welding or by means of adhesive.
  • strip webbing of the above-described type may include conductive material thereby to fonm spatial-1y deformable conductive screens.
  • Such screens are used, for example, as control screens which are incorporated in insulating webbing that is interposed between the high and low-voltage windings of a transformer.
  • the transverse strips consist either of a material that is a poor conductor of electricity, or of a metallic material which is covered with stripping made of poor conductors such as carbon paper and which may additionally be covered with insulating material. The ends of such webbing which project beyond the part on which the webbing is applied may then be rent over in the same manner as in the case of the insulating webbing.
  • the strip webbing shown in FIGURES 1 and 2 may be made by means of a machine such as is shown schematically-in FIGURE 3.
  • a machine such as is shown schematically-in FIGURE 3.
  • the operation of the machine will be described in conjunction with the manufacture of insulating strip webbing,
  • a wide carrier band 13 is taken off a supply roll 12 and passes between two guide rollers 14, to be wound ultimately onto a takeup reel 25.
  • the carrier band 13, during its travel from the guide rollers 14 to the take-up reel 25, is provided with the thin, overlapping transverse insulating strips supplied by two supply rolls 15, 16, that are continuously wound around the band 13. These trans-verse strips are thus spun onto the carrier band 13, in a manner somewhat similar to that in which insulating paper or foil is spun onto fiat wires which themselves ultimately serve as windings for machinery.
  • the transverse strips are shown, in cross section, at 17.
  • an object of the present invention to provide a method and an apparatus for making webbing of the above-described type, namely, webbing which consists of thin transverse strips and longitudinal bands which hold the transverse strips in position, which method and apparatus overcome the above drawbacks, and, with this basic object in view, the present invention resides in the fact that a plurality of transverse strips are, approximate-1y simultaneously, pulled off supply rollers, are thereafter intermittently, i.e., in a step-wise manner, secured to the longitudinal bands, and are cut to the proper length.
  • FIGURES l and 2 are cross-sectional and plan views, respecially, of strip webbing of the type produced by the present invention.
  • FIGURE 3 is a diagrammatic view of a machine in which the webbing of FIG- URES 1 and 2 is produced by continuously spinning transverse strips about longitudinal bands.
  • FIGURE 4 is a diagrammatic plan view of a machine for carrying out the method of making the webbing of FIGURES 1 and 2 in accordance with the present inventron.
  • FIGURE 5 is a side elevational view of the machine shown in FIGURE 4, as viewed from the left side thereof.
  • FIGURE 6 is a front elevational view of the machine of FIGURE 4, as seen in the direction of arrow A in FIGURE 4.
  • FIGURE 7 is an elevational view of a component used in the machine of FIGURES 4 to 6.
  • FIGURE 8 is a plan view of the component shown in FIGURE 7.
  • FIGURES 9 and 10 are sectional views of other types .of strip webbing which may be produced according to the method of the present invention.
  • FIGURE 4 shows approximately twenty transverse strips 26 which are drawn off a corresponding number of supply rolls at the same time.
  • a group of such transverse strips, all of which are processed simultaneously, will hereinafter be referred to as one transverse cluster.
  • each cluster is, as stated, taken off a corresponding number of individual supply rolls. The first of these is indicated at 27, the last at 28.
  • the leftwardmost transverse strip of a cluster is indicated at 29, the longitudinal center line or axis of this strip at 30.
  • the rightwardmost strip is shown at 29a.
  • Each strip is drawn off in approximately horizontal direction and runs past one of the approximately vertically oriented tines 32a of a comb-like member 32, from there to a stationary strip-posioning guide member 33, and from there to a point between a press member 34 member 35.
  • the strip-positioning guide members 33 and 35 serve to position the transverse strips so that the same will lie in the desired overlapping relationship.
  • the components 34, 35 are secured, by means of attaching devices 36, to transport chains 37. These chains run over two sprocket drive wheels 38, 39, which are mechanically connected to each other for rotation, and two idler sprockets 40, 41, so that the components 34, 35, can be drawn to overlie a work table 42.
  • the transport device constituted by the press member 34, the guide member 35, and the attaching devices 36 is movable between the starting position shown in FIG- URE 4, and an end position in which the transverse strips of the cluster, whose end portions are clamped, at points spaced from the extreme ends of the strips, between components 34 and 35, have been drawn transversely so that the extreme free end portions of the transverse strips have come to lie below a press member 43.
  • the press member 43 is brought down thereby to hold in place the strip of the cluster, so that after the components 34, 35, have been separated, the transport device can be withdrawn back to its starting position.
  • the longitudinal holding bands, indicated at 45, are then drawn off supply rolls 44. These longitudinal bands are made to lie immediately above the work table 42 but below the transverse strips of the cluster (see FIG- URE 6).
  • the transverse strips of the cluster are held in place by the press member 43, the transverse strips are pressed down against the longitudinal bands 45 by means of a suitable pressing member 62 (FIGURES and 6).
  • These longitudinal bands 45 will, in practice, be of the self-adhering type, i.e., they will carry a suitable adhesive coating so that once the transverse strips have been pressed down, they will be held by the longitudinal bands 45.
  • the transverse strips of the cluster are pressed down against the longitudinal bands 45, the transverse strips are cut along the line 46, which coincides substantially with the lateral edge of the work table 42, by a knife 67 (FIGURE 5) carried on and movable with the pressing member 62.
  • the pressing member 62 and the press member 43 are then raised, and the take-up reel 47 is rotated to take up so much of the now finished strip webbing that the right-hand edge 48 of the rightwardmost transverse strip 29a of the next cluster will come into proper overlapping rela- 4, tionship with the leftwardmost strip 29 of the cluster that has just been finished. This finishes one cycle of operation.
  • the next cycle of operation commences as soon as the transport device grasps the next cluster and moves the same over the work table 42.
  • transverse strips are taken off a large number of individual rolls. In practice, it is readily feasible to provide 100 or 200 individual supply rolls. If the transverse strips of one cluster overlap by, say, 5 to 10 mm, one cluster can have a width of 50 cm. to 2 meters, as a result of which a very high operating speed and production rate is achieved.
  • each of the rolls are shown, in FIGURE 4, as being spread out in a fan-like arrangement. This makes each of the rolls readily accessible. If each of the rolls is arranged in a suitable cradle in which each roll is guided by the side walls and braked by externally acting pressure springs, a spent roll can readily be replacedfor example, by adhering a wedge-shaped end of a strip from a fresh roll to the strip of the roll that is about to run outwithout it being necessary to stop the operation of the machine.
  • FIGURES 5 and 6 show the pressing means which press the drawn off transverse strip of a cluster against the longitudinal :bands as being constituted by a reciprocatory press member
  • the pressing means may be constituted by equipping the transport device with a press roller which comes down into an operative position while the transport device moves from its end position back to its starting position. Suitable means will then be provided, e.g., a camming device, which raises the press roller during the time that the transport device brings a new cluster over the work table.
  • the longitudinal bands which serve to hold the trans verse strips in place will generally be made of very thin insulating material which, as set forth above, carry an adhesive.
  • the adhesive will be one which will allow the longitudinal bands to be peeled off the transverse strips after the strip webbing has been placed on the apparatus with which it is to be used, thereby to allow the webbing to be spatially deformed, as explained above.
  • the strip webbing is to constitute insulation, not only the longitudinal bands but also the transverse strips will be made of insulating material.
  • the transverse strips and longitudinal bands may be made of different materials; for example, the transverse strips may be made of high quality absorbent insulating paper while the longitudinal bands are made out of high-strength thin plastic foils. Also, the transverse strips and the longitudinal bands may have different thicknesses.
  • the transverse strips will be made of conductive material and the longitudinal bands of insulating material.
  • the transverse strips can be made of conductive paper, e.g., carbon-type paper, or of thin bare metal strips or of metal strips which are covered with a conductive paper coating, or, under certain circumstances, of metal strips which are covered with a conductive paper coating and over that, a layer of insulating material.
  • the purpose of covering the metallic transverse strips with conductive paper is to cover the sharp edges of the metal strips.
  • These conductive longitudinal connections of the transverse strips can be provided at, or just prior to, the final processing of the strip webbing.
  • the machine according to the present invention may include guide members corresponding to the stationary and movable guide members 33 and 35, described above, which guide members comprise thin stripping which is wound at least twice about the path to be followed by the transverse strips 26, so that each of the latter will be guided at both of its edges.
  • FIGURES '7 and 8 Such an arrangement is shown in FIGURES '7 and 8 which includes upper and lower cover plates 82 and 83 (the upper plate 82 having been removed in FIGURE 8 to permit illustration of the parts), between which are two Zig-Zag strips 84, 85, that loop back and forth so as to provide passages through which the transverse strips 26 extend.
  • the passages formed by the zig-zag strips are so arranged that the strips 26 are in multiple overlapping relationship, i.e., each strip 26 overlies not only the immediately adjacent strips 26, but also the strips beyond.
  • the zig-zag strips 84, 85 are secured to the cover plates, or to at least one of them, preferably the lower one, by suitable means such as by riveting or welding.
  • the cover plates are extended beyond the zigzag strips 84, 85, against the direction of travel of the transverse strips 26. Also, the point at which the strips 26 enter the guide member will be narrowed at the cover plates so that already here the strips 26 will assume the proper position.
  • the strip webbing described so far involves the provision of overlapping transverse strips.
  • the strip webbing may be so constructed that the transverse strips of one cluster all lie in the same plane, these strips being either immediately next to each other (FIGURE 9) or spaced apart a small distance (FIGURE 10).
  • the webbing will include a further layer of co-planar transverse strips 26a, as shown in FIG- URES 9 and 10, so that the machine of FIGURES 4 to 6 will include two transport devices, namely, an upper and a lower transport device, the latter being arranged to pull a second cluster of co-planar transverse strips below the longitudinal bands 45.
  • the strips of the upper and lower clusters will be staggered with respect to each other, as illustrated.
  • the press member In order that the press member will cause both layers of transverse strips to be secured to the longitudinal bands 45, the latter will have an adhesive coating on both sides.
  • connection between the longitudinal bands and transverse strips should be such that the longitudinal bands can be peeled off. If, instead of an adhesive connection between the bands and strips, the same are welded together, the welding should be in the nature of a temporary or tacking weld which allows the bands to be removed from the strips.
  • the strip webbing produced in accordance with the present invention is not limited for use as insulation or winding intended for high-voltage machinery, since the strip webbing, being so constructed as to enable it to be spatially deformed after it has been applied, can be used for packaging various types of articles.
