Abstract
The invention relates to a method and multistation device for folding profiles. The folding stations (1, 11, 15, 16, 17) required are modules mounted interchangeable and adjustable on a common machine body (2), which permits quick and simple adaption to the folding requirements. It is thus possible, with one single machine, to implement a whole series of folding processes. With regard to the machine operation, such stations are selected as needed, fitted and set depending on folding criterion.
Claims23
A bending apparatus, comprising:
- a roller bending station for selectively bending a section into any one of a plurality of different bend profiles, the roller bending station having a bending area where a section is bent;
- a guide assembly for guiding a section in a predetermined path into the bending area;
- the bending station having a first, center roller on one side of a section in the bending area, and at least two additional rollers on the opposite side of the section;
- at least the center roller comprising a driven roller;
- and
- the additional rollers each being independently adjustable in an x and y direction.

A bending apparatus, comprising:
- a machine bed along which a section to be bent can be guided;
- a roller bending assembly mounted on the machine bed for selectively bending a section into any one of a plurality of different bend profiles;
- a guide assembly for guiding a section on a predetermined path into the roller bending assembly;
- the roller bending assembly comprising a plurality of separate, modularly exchangeable roller stations each removably mounted on the machine bed, the roller stations comprising a first center roller station positioned in a bending area on one side of a section to be bent, and at least two additional roller stations positioned on the opposite side of the section to be bent;
- each of the roller stations having a roller acting against a portion of a section to be bent;
- at least one of the rollers comprising a driven roller;
- the roller of one of the additional roller stations comprising a guide and rolling roller positioned opposite the roller of the center roller station;
- and
- an adjustment device for pressing the guide and rolling roller against the section to be bent with a predetermined driving force, whereby thrust drive is effected by the mutually opposing rollers.

A method of bending a section into any one of a plurality of different predetermined bend profiles, comprising the steps of:
- selection of a predetermined combination of separate roller stations for co-operating to achieve a predetermined bend profile, including a central roller station for positioning on one side of a section to be bent in a bending area, and at least two additional roller stations for positioning on the opposite side of the section to be bent;
- mounting each of the roller stations separately on a common machine body;
- adjusting the relative positions of the roller stations according to the predetermined bend profile;
- introducing the section to be bent into the bending area between the roller stations;
- positioning one of the additional roller stations such that a guide roller of the additional roller station presses against the section with a predetermined driving force and is positioned opposite an opposing roller of the central roller station and rotatably driving both of the opposing rollers so as to apply a thrust drive to the section to be bent;
- and
- starting the bending process.
