A package support device (10, 40) in the form of an end cap for supporting a tube (11) in a cradle of a textile machine, on which tube (11) a package of yarn is to be wound, is formed of two members (12, 13, 42, 43). A first member (12, 42) has a frusto-conical outer surface (14,44) which in use is inside and co-operates with a tapered bore (17,47) in the second member (13, 43). The second member (13, 43) has a slit (25, 55) so that it can expand as the cylindrical outer surface (20, 50) of the second member (13, 43) engages the bore (21) of the tube (11) and moves the second member (13, 43) towards the larger diameter end (16, 46) of the first member (12, 42). Crushing of the tube (11) on the end cap (10, 40) as yarn is wound on the tube (11) is avoided by movement of the second part (13, 43) towards the smaller end (15, 45) of the first part (12, 42), thereby facilitating automatic doffing of the package from the machine. <IMAGE> |
