Abstract: Device for producing reinforcements, in particular reinforcement baskets for concrete pipes having a bell-shaped socket end, having an expansion device which has a single expansion slide, wherein the expansion slide is configured for modifying, in particular, during the production process of the reinforcement, a radial position of an assigned actuating element for a longitudinal wire of the reinforcement by way of a transmission mechanism of the expansion device. The device is characterized in that the expansion device has a mold slide, wherein an actuator drive is provided for moving the mold slide, and wherein the actuator drive for a linear movement of the mold slide in relation to the expansion slide is supported on the expansion slide.

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 order to make manual work superfluous and to improve the machine performance, a wire feed device is provided which automatically 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 displaced longitudinally with the feed frame (44).
