TUBE CORES FOR PACKAGING ELASTOMERIC FILAMENTS
A tube core for production and delivery of elastomeric filaments, including a tube body, a non-continuous groove or recessed channel formed in an outer wall and proximate to one end of the tube body, and a slip-resistant coating or surface on the outer wall of the tube body. The total angular range traversed by the groove or channel is less than 360° or in the range of 180° to 355° of the circumference of the outer wall of the tube body. The slip-resistant coating or surface includes a colloidal silica, such as a Ludox®, coating or surface. The tube body is constructed from paper. The elastomeric filaments include spandex. The tube core is adapted for over-end-take-off (OETO) applications.
