Abstract: In a buckle for joining band ends together, one band end is provided with longitudinally arranged indentations in or adjacent each side edge, and a channel-shaped, adjustable coupling member of the buckle has teeth therein arranged to register with band end indentations at various relative positions and to penetrate the indentations when the band end is pressed against the coupling member. Presser members fixed to the sidewalls of the coupling member press the teeth into engagement with the indentations to maintain the coupling member in adjusted position. The other coupling member may be a cover which releasably engages with the adjustable coupling member.

Abstract: Band making apparatus comprising a mandrel on which is wound wire of U-shaped cross-section with relatively inverted portions alternating longitudinally of the axis of the mandrel having a side edge interengaged in the channel of the other, has a guide for guiding the wire onto the mandrel provided with a guiding surface which engages the external surface of a side of the wire incoming to the mandrel, and the wire and mandrel are relatively rotated about the axis of the mandrel and reciprocated longitudinally of that axis at a controlled speed ratio such that the back pressure of previously wound turns maintains the incoming wire side against the guiding surface.
