Abstract

1529309 Apparatus for winding piano strings R DUBOIS and P DUBOIS 24 Nov 1975 [28 Nov 1974] 48185/75 Heading B8G [Also in Divisions D1 and G5] To wind a piano string, a member is rotated on a hollow shaft to orbit a reel of auxiliary wire to helically wind the wire on a core wire running through the shaft, the running core wire upstream of the shaft having been deformed in a fixed plane to prevent its rotation during winding. Advancing steel core wire 4, bent by pulleys 5 to prevent rotation, is wound with copper wire 8 from reel 7 on disc 1 rotated via belt 6 by hand crank or an electric motor. Disc 1 may have different diameter belt pulleys to enable the disc to be rotated at different speeds. Spring-biased arm 9 tensions wire 8. Counterweight 11 may be replaced by a further spool 7 for the simultaneous winding of a second wire 8. A device may prevent back-rotation of disc 1. The device may be reversible to permit clockwise or anti-clockwise winding of the auxiliary wire.
