ABSTRACT:
An apparatus particularly adapted for weighing spools of yarn without subjecting the yarn to physical contact, which features an expansible mandrel depending from a weigher and having a lower end adapted to be releasably locked within the core tube of the spool. The mandrel is capable of undergoing movement independently of the weigher to accommodate for axial misalignments of the core tube when presented to the mandrel and to isolate the weigher relative to shocks produced as an incident to alignment and/or pickup of the spool by the mandrel.
