Abstract: Feedback-based systems and methods for bending wire are provided. The systems and methods may allow for modification of wire bending based on feedback received from one or more feedback-generating elements (e.g., image-capturing device(s), computer processing device(s), vision systems, etc.) used for monitoring one or more characteristics of a wire (e.g., shape, size, dimension, angular configuration, etc.) to determine, and provide to various wire-bending components of the system, appropriate modifications to the wire-bending process. Modifications to the wire-bending process may occur in real time without stopping the wire-bending process. Furthermore, a wire may be bent into a sinusoidal wire structure for forming springs for use in various applications.

Abstract: A sinuous spring for a furniture item includes various elements. For instance, a sinuous spring might include bars that are both parallel and non-parallel. The parallel bars might be positioned in a middle segment, and the non-parallel bars might be positioned in opposing end spring segments. A sinuous spring might be fabricated using various devices and methods, such as a wire-fabricating apparatus including a wire-forming mechanism and a length-adjusting mechanism. The wire-forming mechanism includes one or more sets of wire-forming dies that receive a continuously fed wire and that form the wire into a wire-shape configuration (e.g., sinuous-shape configuration). The length-adjusting mechanism includes a set of grooved wheels that receive the formed wire in the grooves and rotate to stretch or compress the formed wire.
