摘要
The invention relates to moulded plastic spools for thread having a groove in which thread can be trapped. A spool 1 is provided for carrying thread windings on which is included a flexible flange 5 mounted at one end. A thread trapping member 8 is adapted to be fitted to such end of the spool so that a surface of the thread trapping member abuts against the surface 5a of the flexible flange to form a groove between the thread trapping member and the flexible flange. The groove can be opened on flexing of the flange for facilitating insertion of thread therein.
