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 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 confi- goration 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 corresonding 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 ahead 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.

Abstract
Description
- 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,
- It is already known to manufacture rolls for rotating heat-recovery devices by winding in superposed relationship one smooth web and one corrugated web of a metal foil, usually an aluminium foil, and joining together the two webs by means of an adhesive or bonding agent of composite type. To wind together the two webs the inner ends thereof are secured on a rotatably driven core sleeve. The smooth web is unreeled from a supply roll onto a spindle provided with a braking mechanism. The webs thus are wound into roll form while under some tension from the smooth web supply roll. Since the torque exercised by the core sleeve increases as the diameter of the winding-on roll increases, 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. Although sufficient amounts of the binding agent may remain on the ridges of the corrugated web after breakage of the bond to allow the ridges to adhere to the smooth web, 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.
- In accordance with the invention are used two superposed webs of which 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.
- The invention will be described in closer detail in the following with reference to the accompanying drawings, wherein
- . Fig. 1 is a schematic view of a machine in accordance with the invention, designed to manufacture rolls consisting of two superposed and interconnected webs of material,
- Figs. 2-4 show in cross-sectional views and on an enlarged scale three different stations of producing one of the webs of material,
- Fig. 5 is a lateral view of the station illustrated in Fig. 4,
- Figs. 6 and 7 are plan views of the roll winding--on station, showing one of the end sections of the latter in different positions,
- Fig. 8 illustrates on an enlarged scale a vertical longitudinal section of the winding-on station at the initial stage of the winding-on,
- Fig. 9 is a similar view showing a later stage of the winding-on,
- Fig. 10 shows on a still larger scale a section through the outer edge of the rotatably driven end section of the winding-on station,
- Fig. 11 is a perspective view of a portion of the roll,
- Fig. 12 shows on an enlarged scale a cross--sectional view through a part of the roll,
- Fig. 13 is a section along line XIII-XIII in Fig. 12 in the longitudinal direction of the roll, and
- Fig. 14 is a partly cut end view of the roll.
- At each end of an
elongate stand 1 are rotatably mountedspindles 2, 3 each one holding asupply roll 4 and 5 of smoothaluminium foil webs station 8 for imparting corrugations to theweb 6 of material, astation 9 for forming indentations at the tops and bases of theridges 10 of the corrugated web, and astation 11 to wind the twowebs roll 12. - The
corrugation station 8 comprises two rotatably drivencooperating rollers web 6 of material is guided so thattransverse 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 thecorrugation station 8.Station 9 consists of two cog-wheel rollers rollers notches 20 formed at the tops of thecogs 21 of the cog-wheel rollers rollers indentations 22 are formed at the ridge tops as well as at the ridge bases. - The
indentations 22 at the tops and bases of theridges 10 are displaced relative to one another by a distance corresonding 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 afterstation 9, on which plate thecorrugated web 6 slides freely while being advanced. The web further travels through a pair of guide ormaster rollers station 11. These rollers control the rotational speed of therollers roll 12. - The
smooth web 7 is advanced from itssupply roller 5. It travels through a pair of cooperating rollers 26 (similar torollers 17, 18) which are provided-with peripheral beads to shaperibs 27 in theweb 7, The pitch of the ribs is identical with the pitch of theindentations 22 formed at the tops and bases of theridges 10. Further, theweb 7 passes aheating device 28, preferably consisting of two nozzles communicating with a source of hot air (not shown). Before reaching the winding-onstation 11 theweb 7 is guided for lateral alignment by means of analigner mechanism 29, whereby is ensured that theribs 27 of theweb 7 are received in nesting relationship intheindentations 22 of theweb 6. Since theweb 7 is heated, it will retract when cooled, α . thus providing safe and secure attachment of the twowebs roll 12 to one another. - The winding-on
station 11 comprises two coaxial and rotatably mountedend sections webs web 7 should have a width which is fractionally (preferably by 2 millimeters) narrower than the width of thecorrugated web 6. Theshaft 32 of one of theend sections 30 is rotatably mounted in abearing 33 in thestand 1 and is driven via asprocket 34 at the outer end of theshaft 32. At the end opposite thesprocket 34 theshaft 32 is shaped as atrunnion 35 on which may be positioned one end of acore sleeve 36 on which thewebs 6,'7 of material are to be wound. Anexpandable clamping sleeve 37 secures thesleeve 36 to thetrunnion 35, and abolt 39 with ahead 38 thereon passes axially through saidclamping sleeve 37, the opposite bolt end being formed with external threads cooperating with internal threads formed on tensioningsleeve 40 which is able to turn inshaft 32 but which is prevented from performing axial movements. - The
opposite end section 31 is by means of itsshaft 41 rotatably mounted in abearing 42 at the outer end of anarm 43, which is arranged to be pivoted outwards by means of alever 45 about avertical shaft 44 provided on thestand 1. In the inner position (Figs. 7, 8 and 9) apin 46 on theshaft 41 engages the free end of the core sleeve 36 (the left-hand end as seen in Figs. 8 and 9). - On the face facing the
opposite end section 31, theend section 30 is provided with around disc 47 of rubber or similar elastic material which by means ofscrews 48 or equivalent members is attached along its inner and outer edges to theend section 30 proper. In the latter are displaceably mounted a large number ofpistons 49 each one of which is provided with ahead 50 positioned in adepression 51 formed in the end section internally of theround disc 47.. Thefree ends 52 of thepistons 49 project beyond therear face 53 of theend section 30. - Upon rotation of the
end sections 30, 31 aroller 54 rolls in contact with therear face 53 of theend section 30, saidroller 54 being rotatably mounted on ashaft 55 at the lower end of aguide bar 56. Theguide bar 56 is vertically displaceable by means of aguide 57 in aguide track 58 formed incolumn 59 mounted above thebearing 33. Theguide bar 56 is connected with anarm 60 projecting down in thegap 61 between theend sections roller 62 positioned approximately level with thepressure roller 54. - When the
arm 43 has been pivoted outwards (Fig. 6) and acore sleeve 36 has been mounted in position with one end placed on thepin 35 and theexpander sleeve 37 clamped thereto, the ends of thewebs core sleeve 36 begins as a result of the rotation of the latter and of theend sections webs ribs 27 engaging in theindentations 22. As one winding turn after the other is wound onto thecore sleeve 36, theroller 62 is gradually lifted, bringing along thearm 60 and thebar 56 including theclamping roller 54. During the rotation of theend section 30 thepistons 49 move past theroller 54 and in doing so they are urged inwards by the latter into contact with theround disc 47 which then projects like a bow somewhat inwards into thegap 61 between theend sections webs shaft 32 is transferred directly to these most recent winding turns and the tensile stress exerted by theweb 7 which is provided with theribs 27 and which is retained in a taut condition by the braking mechanism provided on the unwinding spindle 3, thus is taken by the friction of thewebs end sections core sleeve 36 thus are relieved. Consequently, there is no risk of compression of the winding turns already wound onto the core sleeve. - When the winding of the
roller 12 is completed and the outer winding turn has been fastened with the aid of an adhesive to the underlying winding turn, thearm 43 is again provided outwards and the pressure on theexpander sleeve 37 is relieved. Theroll 12 together with thecore sleeve 37 may now be removed from the machine. In the subsequent cooling of theroll 12 at room temperature the above referred to fixation of the webs takes place owing to the contraction occurring through cooling of the ribbed web. The fixation of the webs to one another means that the finished roll cannot collapse. - The
ribs 27 and theindentations 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 channels A will be turbulent and not laminar. In 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 theribs 27 make for consid- arably improved exchange of heat. - The embodiment as described and illustrated is to be regarded as an example only and the various parts of the machine may be constructively altered in a variety of ways within the scope of the appended claims. For instance, the
roller 54 externally of theend section 30 may be replaced by a slip shoe supported by thebar 56. Also theopposite end section 31 may be fitted with around disc 47 of an elastic material. The slip shoe may have a length and/or width to ensure that it depresses two orseveral pistons 49 at the same time, There are also other ways of relieving the innermost winding turns. An arrangement including the use of pneumatically operated pistons which transfer the pulling force to the outermost winding turn is likewise possible.
