ABSTRACT:
A spool carrier, particularly for winding up textile threads and for centering and clamping spools which are made up of deformable material such as a paperboard or stiff multilayer paper comprises at least one two-member group having first and second members which have interengageable wedge-shaped portions, which are mounted on a spool carrier one after the other in an axial direction. The two members are urged into wedging interengagement by a biasing spring so that the outer member is displaced outwardly into engagement with the spool carrier. A coupling rod mounted for axial displacement within the spool carrier is movable against the biasing means to disengage the first and second members so as to release the spool.
