Abstract
A roll-forming machine has a stand (11) and a row of forming stations (12), which comprise frames (14, 15) for carriers (17, 18) of pair of rollers laterally displaceably mounted on the stand. An intermediate piece (16) is pivotally mounted on each frame for being pivoted about a vertical axis, and two carriers of a pair of rollers are separately laterally displaceably mounted on each intermediate piece. Each carrier of a pair of rollers comprises two axle pins for carrying a forming roller each and the two carriers of a pair of rollers have their axle pins directed towards each other.

A roll-forming machine comprising
- a stand (11) and a row of forming stations (12) comprising frames (14, 15) for carriers (17, 18) of pair of rollers being laterally displaceably mounted on the stand, wherein
- an intermediate piece (16) pivotally mounted on each frame (14, 15) for being pivoted around a vertical axis (I) and two carriers (17, 18) of pair of rollers separately laterally displaceably mounted on each intermediate piece,
- each carriers of a pair of rollers comprises two axel pins (21, 22;
- 31, 32) for carrying a forming roller (19, 20;
- 29, 30) each, and
- the two carriers of a pair of rollers having their axle pins directed towards each other.
A method for roll-forming a sheet metal strip (35) by driving the sheet metal strip through a row of forming stations (17, 18) having pairs of rollers (19, 20;
- 29, 30) directed towards each other and both holding the sheet metal strip therebetween and form the sheet metal strip over roller edges, wherein
- in every second forming station (12) two angles (41, 42) are gradually formed and in every second forming station two other angles (43, 44) are gradually formed.
