  • PATENTEDSEP 12 m2 ill ilil l il w? a ⁇ Y. v a Q v R. QN QM y w QM -S RN m. ⁇ N U ml R ⁇ Q Profiles in the most diverse forms, as well as hollow rails for doors and windows, have been known for a long time past. Similarly, there are numerous methods for the making of such profiles, but they generally show considerable shortcomings from the point of view of economy. Most of the known methods are too complicated to permit the obtention of low-cost profiles. Moreover, the known hollow rails usually have insufficient thermal insulation which especially in the case of widow-frames results in the formation of perspiration water.
  • the present invention is concerned with a method that permits an economical manufacture of hollow rails with improved characteristics by continuous processing of at least two metal hands by means of roll forming tools, joining the lateral longitudinal edges by folded welts. It is characteristic for this method that the metal bands are simultaneously drawn through the rotating forming tools by a tractive force acting from the formed end and that they are not exposed to any advance force in the roll forming tools, but they are formed into rails by a pressureacting on the surface of the bands, and while under the influence of the longituthrough the forming installations, not driven, located there for the profiling of metal bands, then through a greasing station located before the forming installation, through guiding organs to the joining of the travelling, profiled mental bands in a mutual position determined in advance, and through other forming installations, not driven, to the strengthening of the longitudinal edges of the metal bands by means of folded welts.

  • the hollow rail is made in one operation.
  • the method according to the invention can be 'so performed that the metal bands are either drawn forward by the tractive force each time only on a stretch determined in advance and then .shaped into the proposed hollow rail, which is then cut off and the cycle of operation is automatically repeated, or they are continuously drawn forward and transformed into the proposed hollow rail from which each time a predetermined length is separated, without however interrupting the drawing process.

  • two metal bands one beneath the other preferably in aluminum
  • these tools exercise no advance force but pressure on the surface of the metal bands.
  • the upper metal band is first formed into a U profile (FIGS. 3a, b and open downwards, and the two legs are chamfered outwards 90 (FIGS. 5a, b, c and d).
  • the underneath metal band is formed into a lower and narrower U profile, open downwards, with wider legs chamfered outwards (FIG. 4).
  • a shim liner is drawn up, consisting of an elastic band folded up lengthwise (FIG. 7, 8), the lower parts of which tower inwards above the chamfered edge. Then the U profiles thus made are pressed one upon the other with theirchamfered longitudinal edges, and those of the underneath U profile are bent approx. 180 around the longitudinal edges of the upper U profile, which are coated with the shim liner (FIGS. 9a and c), and are pressed into the elastic shim liner which is enclosed all round (FIG. 9d).
  • the metal bands are under a considerable longitudinal traction, they are strengthened in their structure at leastin some of the longitudinal zones by the forming tools, which only press on the surface of the band but do not exercise any upsetting advance force on the same, and they are at the same time straightened by the tractive force.
  • This drawing process during the manufacture of profiles endows the part-profiles and, after their joining, the finished hollow rail with an accuracy to size and a mechanical strength which are superior to those of the hollow rails made by means of driven rotating forming tools, which exert an advance force on the metal bands and/or the part-profiles, upset the material and necessitate a subsequent straightening of the finished hollow rails.
  • the hollow rail manufactured according to the method herein described shows no metallic contact on the longitudinal edges embracing one another between the upper and the lower part-profiles, owing to the shim liner for which a nonmetallic elastic material is used.
  • This characteristic results in a considerable thermal insulation between the two part-profiles, which in the case of windowand door-frames prevents the formation of undesired perspiration water and greatly reduces the thermal losses from inside to outside and vice versa.
  • the transmission of sound between the part-profiles is considerably damped, which practically prevents the occurrence and/or transmission of noises, especially those caused by the opening and shutting of windows and doors.
  • the insulating shim liner is practically enclosed all round by the folded border of the lower part-profile, neither wetness nor light can affect the shim liner, so it practically has an unlimited lifetime.
  • the hollow rails manufactured according to the method herein described are also secured against transverse forces, since the elastic shim liner extends also along the leg of the lower U profile that laps into the inside space of the upper U profile and frictionally connects the lower U profile with the upper one.

  • Device according to claim 13 characterized by a separating device following the profile moved, for straight cuts and cuts in miter at angles adjustable to the profile.
  • Device characterized by forming installations consisting of profile mill cutters, each of which is mounted freely rotating on the front end of a carrying bolt (70, 71, 72, 73), the rear part of which is held in a socket (74, 75, 76, 77) which is fixed on columns and is vertically adjustable to the axis of the bolt for the purpose of adjusting the bolt and the profile mill cutters carried by it relatively to the other carrying bolts mounted on the same columns (78, 79).
  • Device according to claim 10 characterized by multiple-part profile mill cutter whose single parts are rotatable on a carrying bolt freely and independently of each other.
  • Device characterized by forming rollers (12, 13, 14 and 17, l8, 19 respectively) located along the first working path, three of which are in each case disposed, with their axes of rotation inclined towards each other, on-a plane vertical to the metal band running through, during which process the central rollers (13, 18) of each group of three have an axis of rotation parallel with the surface of the metal band and act together with the forming cores (15, 23) or forming rollers (45, 46, 46', 46"), corresponding in each case to the form of the profile, under the metal band, whereas the lateral rollers (12, 14) show an increasing diagonal position of their axes and the last of the groups of three form a split between the three rollers on the one hand and between the forming core or forming roller on the other, which split corresponds to the desired profile of the metal band.
  • Device according to claim 18 characterized by analogous groups of forming rollers, located along a second working path, whose last group of three forms a split corresponding to a second profile of metal band which is difi'erent from the first profile.
  • Device according to claim 19 characterized by a disposition of the second working path vertically below the first working path.
  • Device according to claim 10 characterized by a threading device located on at least one working path (1) behind the forming installations (17, 18, 19), consisting of sheet-metal deflectors (35, 36) for drawing a profiled shim liner (33, 34) onto the longitudinal rims (21, 22) ofa formed metal band (4).
