ABSTRACT:
An apparatus for bending hollow moldings into spacer frames (44) for insulating glass comprises two bending heads (12) displaceably arranged along the rim of a plate (10), a clamp (13) being provided between these bending heads for the hollow molding to be bent into the spacer frame (44). In this apparatus, a device (20) is provided for feeding hollow moldings which extends in parallel to the rim of the plate (10) at which the bending heads (12) are arranged. Furthermore, a gripper (30) is provided in the plane of symmetry of the clamp (13) for transferring the hollow moldings from the conveying device (20) into the clamp (13) and the bending heads (12).
