ABSTRACT:
An apparatus for the production of spacer frames (44) by bending hollow moldings comprises two bending heads (12) displaceably arranged along a plate (10); with the aid of these bending heads, a hollow molding fed thereto can be bent into a spacer frame (44). At the rim of the plate (10) of the bending apparatus (1) lying in opposition to the bending heads (12), a conveyor slide (50) is provided which transports the hollow moldings, bent into a spacer frame (44), to a transfer device (60), this transfer device (60) lifting the spacer frames (44) conveyed thereto off the plate (10) and transfer them into a welding unit (5) for welding together the free ends (45) of the hollow molding bent into a spacer frame (44).
