Abstract (en)
[origin: EP0894553A2] The apparatus (1) bends a hollow profile section (2) to form an inner (or distance) frame for an insulating glass pane. It incorporates a guiding and holding unit (3), a bending tool (11), a support element (13) and a holding down unit. The holding down unit is made up of two parts (171, 172). The part (171) located in the bending region (4) is rotatable in the bending direction at least through the bending angle. The axis of rotation (18) of this part of the holding down unit is located in the neutral layer of the profile section, or it is radially offset from this layer towards the interior of the bend. The part (172) of the holding down unit is fixed and precedes the other part (171) in the feed direction.
