? Abstract: A machine for producing reinforcing cages for concrete pipes is described, the reinforcing cages comprising longitudinal wires and a winding wire wound around them and welded to them at the intersections. In a machine of this type, the longitudinal wires are cut to length in advance, in a known manner, and are inserted into the machine through collecting funnels (9). In order to make manual work superfluous and to improve the machine performance, a wire feed device is provided which auto- matically fits the machine with the required longitudinal bars before each winding process. The device comprises a feed apparatus (21) for a plurality of wires (33), adjoining guide tubes (37), whose mouths are aligned with the collecting funnels (9), and a cutting device (38). The said machine parts may be combined to form a feed frame (44) which can be displaced longitudinally altogether. Guide mouthpieces (39) are distributed uniformly over the circumference on the same diameter as the cutting devices (38) on a supporting disk (51) which is rotationally fixed to the main disk but can be dis- placed longitudinally with the feed frame (44). When there are fewer feed channels than the maximum number of longitudinal bars which can be inserted, the fitment process takes place in a cyclic method which permits a plurality of fitment variants.
