2130912 9416131 PCTABS00033 In a method of and machine for forming a non-woven bias yarn assembly (10) comprising two superposed non-woven bias yarn sub-assemblies, each yarn (11, 12) is transferred by a yarn transfer member (22) from an opening it occupies in a yarn guide member (21) to another opening in the yarn guide member (21) in such a manner that each yarn (11, 12) is caused in a succession of forward transfer steps to follow the yarn preceding it from one opening to another along a non-intersecting path until the yarn (11, 12) at a first end opening in the path arrives at a second end opening in the path located at the opposite end of the path and the yarn (11, 12) at the second end opening in the path arrives at the first end opening and then in a succession of return transfer steps to follow the yarn preceding it from one opening to another along the non-intersecting path in the opposite direction until the yarn (11, 12) from the second end opening in the path arrives at the first end opening and the yarn (11, 12) from the first end opening arrives at the second end opening. The forward and return transfer steps are then successively repeated. |
