Abstract (en)
A method and device for covering a core yarn (11a) with at least one covering yarn helically wound or wrapped around the core yarn. According to the invention a bobbin (11) of core yarn (11a) is supported by a bobbin supporting member (10) idly journaled to an upper shaft (12) having a first bore means (26) for guiding the core yarn (11a) and a second bore means (30) for guiding the covering yarn (10). The covering yarn (10) is in its turn fed along an arch-shaped guide means (17) rotatably connected with said upper shaft (12) to rotate around the core yarn bobbin (11). The covering yarn is helically wrapped onto the core yarn (11a) by causing said covering yarn in said path (28) to rotate around the bobbin (11) of core yarn and means (15, 16) are provided for preventing the bobbin supporting member (10) to rotate.
