Definitions
- the invention relates to a roll forming apparatus as defined in the preamble of claim 1. Further, the invention relates to a method as defined in the preamble of claim 13. The invention also relates to a gutter profile as defined in claim 19.
- a known half-round gutter profile to be made using the apparatus has a front edge, a rear edge and a substantially semi-circular U-shaped bottom between the front edge and the rear edge.
- the terms “front” and “rear” to be used herein define the assembly position of the gutter in relation to a building.
- the "front edge” of the gutter denotes an edge projecting away from the building, i.e. forward, and the “rear end” denotes a gutter edge directed toward the building.
- the upper end of the front wall has an inward bent, substantially U-shaped first fold.
- the first fold has an outward directed lower branch bending via a U curve to form an inward directed upper branch on top of the lower branch.
- the free end thereof has a second fold which is folded underneath the upper branch and is smaller than the first fold.
- the second fold of the front edge is V-shaped and has a sharp fold angle.
- the gutter profile On the opposite side, i.e. on the rear edge side, the gutter profile has a rear wall whose upper end has an inward bent hook-like third fold.
- the roll forming apparatus known from the publication includes an apparatus frame.
- a sheet metal web enters the roll forming apparatus at a feed end and moves through the apparatus in the feed direction, and a formed final gutter profile exits the roll forming apparatus at an exit end.
- Mounted on the apparatus frame are a number of pairs of forming rolls arranged consecutively at a distance from one another between the feed end and the exit end.
- Each forming roll pair includes a concave roll (usually the lower roll) and a convex roll (usually the upper roll) for stepwise forming a half-round gutter shape.
- the prior- art apparatus has edge bending devices for forming a first fold, a second fold and a third fold in the gutter profile.
- Apparatuses of this kind can be used in factory conditions, or preferably, be transported to a construction site to the assembly site of gutters, where the apparatus can be used to make so-called jointless gutters of a desired length in the buildings.
- Gutters such as these can be installed in the building in the form of even rather long continuous portions, even in the form of ones reaching up to 20 - 30 meters. Due to this, it is important that the finished gutter profile shows sufficient flexural and torsional rigidity, so that it can be treated without breaking at the construction site.
- Prior-art devices and methods, as well as the half-round gutter profiles made using them have the problem that the gutter tends to twist about its longitudinal center of torsion toward the front wall, because that side of the gutter has been shaped more.
- a further problem is that a V-shaped fold in a gutter profile is disadvantageous with respect to the torsional and flexural rigidity.
- One specific objective of the invention is to disclose a roll forming apparatus and method that can be used to make a straight non-twisting gutter profile.
- One further objective of the invention is to disclose a gutter profile having sufficient flexural and torsional rigidity to enable such a permanent deformation in conjunction with the manufacture that will eliminate the tendency to twist.
- the roll forming apparatus of the invention is characterized by what has been presented in claim 1. Further, the method of the invention is character- ized by what has been presented in claim 13. In addition, the half-round gutter profile of the invention is characterized by what has been presented in claim 19.
- the roll forming apparatus of the invention includes an apparatus frame; a feed end via which a sheet metal web is fed into the roll forming apparatus; and an exit end via which a formed final gutter profile exits the roll forming apparatus.
- a number of pairs of forming rolls are arranged consecutively at a distance from one another in the apparatus frame between the feed end and the exit end.
- Each forming roll pair includes a concave roll and a convex roll for stepwise forming a half-round gutter shape.
- the roll forming apparatus includes a first edge bending device which is connected to the apparatus frame for forming said second fold.
- the roll forming apparatus includes a second edge bending device which is connected to the apparatus frame for forming said third fold.
- the roll forming apparatus includes a third edge bending device which is arranged in the apparatus frame after the pairs of forming rolls in the feed direction in the vicinity of the exit end for forming said first fold.
- the third edge bending device includes first adjusting means for making vertical, lateral and tilting adjustments for guiding the gutter.
- the roll forming apparatus includes second adjusting means which are arranged in the apparatus frame in the vicinity of the exit end and which are in co-operation with the first adjusting means to eliminate the non-desired tendency of the gutter profile to twist about the center of torsion toward the more powerfully bent front wall which is provided with a first fold and a second fold.
- a sheet metal web is roll formed in stages from the edges toward the middle to achieve a half-round gutter shape.
- a second fold is formed in the front edge; a third fold is formed in the rear edge; and further a first fold is formed in the front edge.
- the proceeding of the gutter profile is controlled.
- the roll forming apparatus and method have the advantage that they can be used to achieve a straight and non-twisting gutter profile that keeps its shape, does not twist - not even in the form of longer portions - nor buckle or fold.
- the half-round gutter profile of the inven- tion which is formed from a sheet metal web, has a front edge, a rear edge, and a substantially semicircular U-shaped bottom between the front edge and the rear edge.
- At the upper end of the front wall there is an inward bent, substantially U-shaped first fold having an outward directed lower branch bending via a U curve to form an inward directed upper branch on the top side of the lower branch, and the free end thereof has a second fold which is folded underneath the upper branch and is smaller than the first fold.
- At the upper end of the rear wall there is an inward turned hook-like third fold.
- the second fold is U-shaped to improve the torsional and flexural rigidity of the gutter profile.
- This fact provides the advantage that the U- shaped second fold makes the gutter profile sufficiently torsionally rigid so that it can be wrenched about its center of torsion into the opposite direction in relation to its natural tendency to twist, so that a permanent deformation is achieved in the gutter profile that eliminates the aforesaid tendency to twist, and the resulting gutter is straight and non- twisting.

- Fig. 1 shows a roll forming apparatus that can be used to make a half-round gutter profile 1 from a planar sheet metal web 2.
- the web to be shaped to form a gutter consists of a 0.5 mm or 0.6 thick, two-sides paint coated, hot galvanized steel sheet. It is also possible to use a plastisol or PVDF (polyvinyl difluoride) coated metal sheet. It is also possible make a gutter profile from other metals, such as from an aluminum or copper sheet metal web by roll forming.
- the sheet metal web is in the form of a reel. The reel can be supported e.g. on a reel holder (not shown) disposed on top of the roll forming apparatus .
