Definitions

  • the improved honeycomb roll of this invention eliminates radial slots, by including a straight longitudinal strip alternately with each undulate, or sinuate, bent strip, the straight strip having right angularly bent integral tongues, brazed to the inner face of the end members.
  • the apertures are thus half, rather than full, hexagon in configuration but the straight longitudinal strips add considerable resistance to compression, or distortion and the strip material can be of reduced thickness to partially compensate for any loss in area of the ow apertures.
  • the principal object of the invention is to provide a low cost, rugged, honeycomb roll, having suicient strength to resist compression or distortion when used in various mill applications, for example, as a suction roll, dotler roll or support roll.
  • Another object of the invention is to provide a roll having a cylindrical honeycomb openwork with alternate straight and undulated thin metal strips, the nodes being connected to the straight strips by a zinc alloy llayer and the straight strips having tongues aixed to the end members by a silver braze.
  • A' further object of the invention is to provide such la roll with serrated outer edges on the strip for .point support of Work,l with cooperating holes and dimples at the nodes of the strips for a mechanical mutual support and to provide strips of tapered cross section to increase the area of the ow passages, or apertures.
  • Still another object of the invention is to provide such a roll wi-th an inner stationary hollow cylindrical shell, solid and imperforate in the lower portion and formed of honeycomb strips in the upper portion, the honeycomb roll being resistant to centrifugal force to maintain a slight clearance between the inner cylinder and outer roll.
  • FIGURE 1 is a front view, in section on line 1-1 of FIGURE 2, of an improved roll constructed in accordance with the invention
  • FIGURE 2 is an end view in section on line 2 2 of FIGURE 1;
  • FIGURE 3 is an enlarged fragmentary end view showing the nodes connected to the straight strips by a layer of zinc;
  • FIGURE 4 is a view similar to FIGURE 3 showing the nodes mechanically connected by holes and dimples;
  • FIGURE 5 is a similar View showing a straight strip of less height than the height of the bent strips
  • FIGURE 10 is a fragmentary isometric view of a iine, thin honeycomb layer constructed in accordance with the invention using strips of the type shown in FIGURE 9, and
  • FIGURE ll is an end view, in section showing a roll constructed in .accordance with the invention supporting a layer of liner honeycomb on the outside and having a combined solid and honeycomb cylinder in the inside.
  • the improved rotary cylindrical roll 25, of the invention includes a pair of oppositely disposed, parallel, longitudinally spaced, circular end members 26 and 27, with the hollow, cylindrical, honeycomb openwork 28 extending therebetween.
  • Each end member is preferably supported on a stationary hollow bearing journal 29, by means of a bearing plate 30 and bearing 31, the hollow journal forming a uid conduit 32 connecting the interior of the roll to a source of positive or negative air pressure 33.
  • Each end member also includes an annular, peripheral, inner face such as 35 or 36, the faces 35 and 36 preferably being hat, smooth and normal to the longitudinal axis of the roll.
  • the end members are unslotted, and are, conveniently, in the form of circular, flanged rings 37 detachably secured to the bearing plates 30.
  • the hollow cylindrical honeycomb openwork 28 has a cylindhical outer face 38 and cylindrical inner face 39 and is formed of thin metal strips, such as stainless steel, upstanding on edge and bent to form radially extending ilow passages into the interior of the roll.
  • Openwork 28 consists of a .plurality of alternate straight, thin strips such as 41, 42 and 43 and undulated, sinuate or half hexagonally bent thin strips 44 and 45, the strips extending axially from the inner face 35 of one end member to the opposite inner face 36 of the other end member.
  • the terms undulate and sinuate are used herein to include half hexagonal bent strips, or any other equivalent configuration which will produce a useful .pattern of ow passages, a useful embossing pattern, or the like.
  • the preferred coniiguration is that shown, in which the nodes 46 and 47 of adjacent bent strips are oppositely disposed and half hexagonal to jointly define a full hexagon, split by a straight strip such as 42.
  • the outer faces 48 and 49 are elongated and flat to ilatwise engage the corresponding area 50v and 51 of the adjacent straight strips.
  • the flat outer faces 48 and 49 of all of the nodes of all of the bent strips such as 44 and 45 are firmly and securely united to the straight strips by connecting means 52, which is preferably a layer 53 of relatively hard infusible metal, for example a zinc dip.
  • the honeycomb structure is dipped in a bath of pure molten zinc for excellent results.
  • connecting means may be used, for example, mechanical interlocking means in the form of spaced holes 54 in the straight strips and spaced dimples 55 and 56 impressed in the bent strips, the dimples of adjacent nodes meeting within the hole of the straight strip therebetween (FIG. 4).
  • each straight strip 58 corresponding to straight strips 41, 42 and 43, may be of lesser height than the adjacent bent strips -59 and 60, corresponding to strips 44 and 45.
  • 'I'he straight strips 58 may be posiitoned midway of the height of the bent strips 59 and 60, the nodes 61 and 62 of the latter being crimped as at 63 and 64 for mutual interlocking, and a layer 65 corresponding to layer 153 may also be used to unite the nodes laterally to the straight strips.
  • the straight strip 67 corresponding to strips 41, 42 and 43.is of less height than the bent strips 68 and 69 corresponding to strips 44 and 45, and is of tapered cross section with the Wider edge 70 on the outside and thethinner edge 71 on the inside of the openwork.l
  • the strips 67 are at the outside face of the openwork in FIGURE 6, intermediate of the faces of the openwork in FIGURE 7 and at the inside face of the openwork in FIGURE 8.
  • the bent strips 68 and 69 may be flat and uncrimped as in FIGURE 6, or the nodes 72-and 73 may vbe dimpled, embossed or crimped, toward each otherV to form a seat for the straight bar.
  • a suitable layer such as 53, may also be used to unite the nodes 72 and 73 to each other and to the straight strips 69.
  • a plurality of liat strips 74 may be formed with sharp pointed teeth, or serrations, 75, then bent into sinuate configuration, as shown at 76 and alternated with straight strips 77 having tongues 78 to create a honeycomb openwork 79,
  • the multiplicity of teeth 75 provide point support to a sheet-like work carried on a roll such as 25, or the openwork 79 may be used as card clothing on a carding roll, doffer roll or the like. 4For additional point support, the straight strips 77 may also have serrated upper edges.
  • All of the straight strips 41, 42 and 43 of the openwork 28, and all of the other embodiments of the straight Vstrips shown at 58, 67 and 75 are provided with integral right angularlyfbent tongues such as 80, 81, 82, 83, 84 and 85 at the opposite terminal ends thereof.
  • the outer face 86 of each tongue is in atwise engagement with the inner, peripheral face 35 or 36 of the adjacent end member 26 or-27 and a layer 87 of relatively hard infusible alloy firmly and securely afiixes the tongue to the face.
  • the layer 87 is preferably a low temperature silver braze alloy 88, this having been found yto support the ends of the openwork between the inner faces under extreme stresses and strains caused by compression and centrifugal forces on the openwork during rotation or by temperature caused expansions and contractions of the openwork.
  • a very satisfactory low temperature silver braze alloy for the above purpose, is Easy-Flo 45 commerically available from Handy & Harman ⁇ of Bridgeport, Connecticut, this product being 45% silver and -owing freely at about l145 F.
  • FIGURES 5, 7 and 8 may be used, the straight strip being below the level of the outer face of the openwork and the nodes being embossed and olfset at the outer diameter into node to node contact.
  • the area of the inside of each cell remains about equal to the area of the outside of each cell, while still providing space at the outside of the openwork for a straight strip alternated with each bent strip, for example as shown in FIGURE 6.
  • the roll -25 of the invention is provided with a second cylindrical, honeycomb openwork 90, substantially identical in structure with the openwork 28 and affixed to the inner faces of the roll end members by the tongues 91 of the straight strips 92.
  • the straight strips 92 and undulate strips 93 are of smaller dimensions than the strips of openwork 28 so that the flow passages 94 are relatively fine and the openwork is relatively thin as compared to the relatively thick and coarse openwork 28.
  • the fine, thin openwork 90 may thus be used for delicate embossments while supported by the more rugged openwork 28.
  • the outer face 98 of cylinder 97 has a slight clearance from the inner face 105 of roll 251, the clearance being maintained during rotation of the roll because of the improved construction of the roll 25V.
  • a suitable air conduit means 99, ⁇ corresponding to the hollow bearing ⁇ journal 29, is provided to connect the interior of the cylinder 97 with the air source 33.
  • the roll 25 may thus be used as a rotating suction roll, with a stationary suction box therewithin in the form of cylinder 97 and the .honeycomb shell 96 forms an effective seal in combination with slidable side walls or deckles not shown.
  • the bonding agent used for layer 53 whether zinc, solder, epoxy resin or silver braze alloy, flows between the interfaces of the strips but zinc dipping is preferred, for the layers ⁇ 53, because the ⁇ zinc completely covers the strips to protect the mild steel therein from rusting.
  • a rotary cylindrical roll comprising:
  • said means connecting said nodes to said straight strips i is a layer of zinc.
  • said means connecting said nodes to said straight strips comprises a plurality of spaced holes in each said straight strip
  • a rotary cylindrical roll as specified inclaim 1 wherein:
  • each said str-aight strip is of the less height than said undulated strips, and each said ⁇ straight strip ⁇ is ⁇ mounted at the same radial distance from the axis of said roll.
  • each said straight strip is of tapered cross section
  • a second cylindrical honeycomb openwork lsupported on the outside of said first mentioned cylindrical honeycomb openwork, said second openwork being relatively thin and line and said rst face being relatively thick and coarse.
  • said shells mutually forming -a full hollow cylinder having a slight clearance from the inside of said roll
  • air conduit means leading from the interior of said shells to the exterior thereof.
  • a hollow cylindrical roll comprising:
  • said openwork having alternate straight, and half-hexagon-ally bent, thin, metal, strips, secured to each other at the nodes of said hexagons for mutual support, and
  • said straight strips each having an integral right angular tongue at each opposite end thereof secured to one of said annular, peripheral inner faces for supporting said openwork on said roll ends.
  • a doier roll comprising:
  • a hollow cylinder having a pair of circular end members, each including a roll bearing 'and each having an nner face normal to the -axis ofthe roll;
  • va honeycomb openwork extending between said end members, said openwork being formed by a plurality of thin, longitudinally extending, alternately straight and sinuate strips, said straight strips terminating at each opposite end in an integr-al right angular tongue silver brazed to the inner face of one of said roll ends for supporting said openwork;
  • journal supporting said roll bearings, said journal forming a conduit for con necting the interior of said roll to a source of positive or negative lair pressure.
