Abstract: A method of forming a wound musical instrument string wherein a core wire is fed axially along a preselected path while being rotated at high speed and a wrap wire is caused to be wrapped about the advancing rotating core wire. The wrapped core wire may additionally be driven. The drive may comprise rollers engaging the core wire prior to the wrapping operation and may include rollers engaging the wrapped wire subsequent to the wrapping operation.

Abstract: A panel connector for use in connecting a plurality of panels such as to form a display. The connector is defined by a spring clip, of suitable length, forming an arcuate bead on the edge of the panel to be connected and adapted to be received in a complementary socket element. The clip includes inturned legs providing an improved support of the panel edge, maintaining the panel edge centered in the clip and against undesirable outward movement of the panel from the clip. The socket element may be arranged to permit selective angular disposition of the panel through a preselected wide angular range for facilitated arrangement of the panels as desired. The socket element may define a plurality of sockets for receiving a corresponding plurality of panel edges and opposite edges of the panels may be connected to different socket elements to permit a series arrangement of the panels and socket elements.
