Definitions

  • the invention concerns a roll that is manufactured from two superposed webs, one of which is corrugated.
  • the roll is primarily intended for use in so called regenerative heat exchangers.
  • the adhesive bond between the smooth web and the ridges of the corrugated web will brake at a certain degree of tension in the smooth web on account of the braking force exerted by the un-winding spindle, and as a result one or several of the winding turns of the webs will separate from one another. As a consequence, the entire roll might collapse when it is transferred to a hardening oven for setting of the adhesive.
  • the adhesive on the smooth web at the original points of adherence will, however, in this case be positioned on the gap between the ridges with the consequential disadvantage that the cross-sectional area for air passage through the rotatably driven roll of the heat-recovery devices diminishes.
  • the purpose of the subject invention is to eliminate the glueing operation completely while at the same time provide considerably more efficient exchange of heat than in heat exchangers fitted with rolls of prior-art types.
  • the first web is provided with transverse equidistantly spaced ridges whereas the second web is provided with longitudinal ribs.
  • the characteristic feature of the invention resides therein that the ridges of the first web are provided at the ridge tops as well as at the ridge bases with indentations having a pitch matching that of the ribs formed in the second web, in which indentations engage said ribs formed in the second web.
  • the invention also concerns a method of manufacturing the roll, which method is characterised by the steps of forming indentations on the ridges in the first web at the ridge tops as well as the ridge bases, said indentations having a pitch matching that of the ribs formed in the second web, and guiding at least one of the webs so as to ensure that the ribs are positioned in said indentations.
  • the invention likewise comprise a machine for manufacturing the roll in accordance with the invention, the machine being characterised in that it comprises first means arranged during the advancement of the second web to form longitudinal ribs in said web, second means arranged during the advancement of the first web to form indentations at the ridge tops as well as at ridge bases of the first webs, said indentations having a pitch matching that of the ribs, and third means arranged to control one and/or both webs to ensure that the ribs of the second web will engage on the indentations of the first web.
  • an elongate stand 1 At each end of an elongate stand 1 are rotatably mounted spindles 2, 3 each one holding a supply roll 4 and 5 of smooth aluminium foil webs 6 and 7.
  • the stand also supports a station 8 for imparting corrugations to the web 6 of material, a station 9 for forming indentations at the tops and bases of the ridges 10 of the corrugated web, and a station 11 to wind the two webs 6 and 7 into a roll 12.
  • the corrugation station 8 comprises two rotatably driven cooperating rollers 13, 14 of cog-wheel appearance between which rollers the web 6 of material is guided so that transverse ridges 10 are formed therein.
  • Station 9 which is the station in which the indentations are formed at the tops and bases of the ridges is positioned after the corrugation station 8.
  • Station 9 consists of two cog-wheel rollers 15, 16 and two back-up rollers 17, 18. The latter are provided with peripheral beads 19 (see Fig. 6) having a shape matching the configuration of notches 20 formed at the tops of the cogs 21 of the cog-wheel rollers 15, 16. Because of the flow of material in the press nips formed by the rollers 15, 17 and 16, 18, respectively, indentations 22 are formed at the ridge tops as well as at the ridge bases.
  • the indentations 22 at the tops and bases of the ridges 10 are displaced relative to one another by a distance corresponding to half a pitch (see Fig. 13), thus ensuring that the internal through-flow area remains constant over the entire length of the channel A thus formed.
  • a support plate 23 is arranged after station 9, on which plate the corrugated web 6 slides freely while being advanced.
  • the web further travels through a pair of guide or master rollers 24, 25 positioned a head of the winding-on station 11. These rollers control the rotational speed of the rollers 13, 14 in relation to the winding-on speed of the roll 12.
  • the smooth web 7 is advanced from its supply roller 5. It travels through a pair of cooperating rollers 26 (similar to rollers 17, 18) which are provided with peripheral beads to shape ribs 27 in the web 7.
  • the pitch of the ribs is identical with the pitch of the indentations 22 formed at the tops and bases of the ridges 10.
  • the web 7 passes a heating device 28, preferably consisting of two nozzles communicating with a source of hot air (not shown).
  • the web 7 is guided for lateral alignment by means of an aligner mechanism 29, whereby is ensured that the ribs 27 of the web 7 are received in nesting relationship in the indentations 22 of the web 6. Since the web 7 is heated, it will contract when cooled, thus providing safe and secure attachment of the two webs 6, 7 forming the roll 12 to one another.
  • the winding-on station 11 comprises two coaxial and rotatably mounted end sections 30, 31.
  • the distance separating the end sections in the operative position is approximately equal to the width of the webs 6, 7 of material, of which the ribbed web 7 should have a width which is fractionally (preferably by 2 millimeters) narrower than the width of the corrugated web 6.
  • the shaft 32 of one of the end sections 30 is rotatably mounted in a bearing 33 in the stand 1 and is driven via a sprocket 34 at the outer end of the shaft 32.
  • a trunnion 35 At the end opposite the sprocket 34 of the shaft 32 is shaped as a trunnion 35 on which may be positioned one end of a core sleeve 36 on which the webs 6, 7 of material are to be wound.
  • An expandable clamping sleeve 37 secures the sleeve 36 to the trunnion 35, and a bolt 39 with a head 38 thereon passes axially through said clamping sleeve 37, the opposite bolt end being formed with external threads cooperating with internal threads formed on tensioning sleeve 40 which is able to turn in shaft 32 but which is prevented from performing axial movements.
  • the opposite end section 31 is by means of its shaft 41 rotatably mounted in a bearing 42 at the outer end of an arm 43, which is arranged to be pivoted outwards by means of a lever 45 about a vertical shaft 44 provided on the stand 1.
  • a pin 46 on the shaft 41 engages the free end of the core sleeve 36 (the left-hand end as seen in Figs. 8 and 9).
  • the end section 30 On the face facing the opposite end section 31, the end section 30 is provided with a round disc 47 of rubber or similar elastic material which by means of screws 48 or equivalent members is attached along its inner and outer edges to the end section 30 proper.
  • a large number of pistons 49 each one of which is provided with a head 50 positioned in a depression 51 formed in the end section internally of the round disc 47.
  • the free ends 52 of the pistons 49 project beyond the rear face 53 of the end section 30.
  • a roller 54 rolls in contact with the rear face 53 of the end section 30, said roller 54 being rotatably mounted on a shaft 55 at the lower end of a guide bar 56.
  • the guide bar 56 is vertically displaceable by means of a guide bar 56 is vertically displaceable by means of a guide 57 in a guide track 58 formed in a column 59 mounted above the bearing 33.
  • the guide bar 56 is connected with an arm 60 projecting down in the gap 61 between the end sections 30, 31 and at the lower arm end is rotatably mounted a load-exerting roller 62 positioned approximately level with the pressure roller 54.
  • the roller 62 is gradually lifted, bringing along the arm 60 and the bar 56 including the clamping roller 54.
  • the pistons 40 move past the roller 54 and in doing so they are urged inwards by the latter into contact with the round disc 47 which then projects like a bow somewhat inwards into the gap 61 . between the end sections 30, 31. This exerts a lateral presure on the most recently formed winding turns of the webs 6, 7, whereby these winding turns are clamped in position between the end sections. This means that the pulling force.
  • the ribs 27 and the indentations 22 form through-flow channels A for the medium flowing through the heat exchanger of the appearance shown in Fig. 13.
  • This configuration results in an enlargement of the heat-transmission area and also means that the flow through the channel A will be turbulent and not laminar.
  • laminar flows which would have been the case had the limiting faces of the channels been completely straight
  • the layer of the medium flowing closest to the limiting faces acts as insulation, preventing the rest of the medium from contacting these faces.
  • the turbulent flow generated in the channels of the roll in accordance with the invention means that a larger portion of the flowing medium will come into close contact with the limiting faces.
  • the effect of this phenomenon and of the enlargement of the heat-transmission area of the channels A as a result of the provision of the ribs 27 make for considerably improved exchange of heat.
  • roller 54 externally of the end section 30 may be replaced by a slip shoe supported by the bar 56.
  • the opposite end section 31 may be fitted with a round disc 47 of an elastic material.
  • the slip shoe may have a length and/or width to ensure that it depresses two or several pistons 49 at the same time.
  • An arrangement including the use of pneumatically operated pistons which transfer the pulling force to the outermost winding turn is likewise possible.
