Method for fabricating a string, in particular a string for a bowed musical instrument, and an apparatus for carrying out the same

Method for fabricating a string having a cylindrical core with at least one winding strand helically wound thereon, the method comprising:

• placing a cylindrical core axially along a path,
• spinning the cylindrical core about its central axis and helically winding at least one winding strand around the cylindrical core at a spinning point, the spinning point being a point of first contact between the cylindrical core and the at least one winding strand,
• applying at the spinning point both a friction force and a compression force to the at least one winding strand by a compactness increasing module, while helically winding the at least one winding strand around the cylindrical core,
• wherein the compactness increasing module comprises only one contact plate, said contact plate being shaped as an open ring, and the ring is arranged such that the cylindrical core with or without one or more winding strands wound thereon passes through the ring, and wherein during spinning the compactness increasing module is moved, such that the compactness increasing module follows the spinning point.

String fabricating apparatus for fabricating a string, having a cylindrical core with at least one winding strand helically wound thereon, the apparatus comprising:

• means for spinning a fixed cylindrical core of a string about its central axis, and means for helically winding at least one winding strand on to said cylindrical core at a spinning point, the spinning point being a point of first contact between the cylindrical core and the at least one winding strand as the cylindrical core spins, thereby forming a string with at least one cylindrical core and at least one winding layer, and
• a compactness increasing module configured to be in contact with the at least one winding strand or a current uppermost winding strand at the spinning point when the at least one winding strand or the current uppermost winding strand is wound onto the string, such that both a friction force and a compression force are applied at the spinning point between the compactness increasing module and the at least one winding strand during spinning, leading to increased compression of the at least one winding strand and the string,
• wherein the compactness increasing module comprises one contact element, said contact element being shaped as an open ring arranged such that the core passes through the open ring, wherein during spinning the compactness increasing module is moved, such that the compactness increasing module follows the spinning point.
