Abstract (en)

In order to secure the end of roving (5) on cops (9) on removal from a fly frame it is proposed initially to lower cop carriage (2) to a position such as to bring the top end of bobbins (4) to the height of compressor (16) of flyers (6), then to rotate cops (9) a few turns to wind roving (5) into a groove (17) or onto a roughened or similar surface of bobbins (4) capable of retaining roving (5), after which carriage (2) is further lowered or inclined to cause roving (5) to snap in the section between the end of bobbins (4) and flyers (6). Preferably, before lowering cops (9), a reserve of roving (5) is created by slowly rotating flyers (6) and cops (9) for a few turns with no supply, simultaneously imparting a twist to roving (5) and strengthening it. <IMAGE>
