ABSTRACT:
A self-contained unit for the re-stringing of a bow for a musical instrument as a replacement for the traditional horse hair comprises a hank of reorientated monofilaments each containing at least a substantial proportion of polyvinyl chloride and having a diameter in the range of 0.15 to 0.40 mm. The adjacent free ends of the monofilaments are bonded together to form an enlargement at each end of the hank and these are preferably trapped mechanically in recesses at the ends of the bow although they can be glued in position in the traditional manner if required. When the unit is fitted mechanically the frame of the bow has at one end a recess with a restricted mouth fitted with a spring-loaded member for jamming the mouth under the spring force, but capable of yielding inwardly to permit the introduction of an enlargement at the end of the unit, and at the other end it has an adjustable frog formed with a recess provided with a longitudinally slidable cover.
