ABSTRACT:
In the formation of an elastomeric tube or the like on a toroidal core, elastomeric material is applied to the core generally along one side of the core, and force-applying means are utilized to press annular portions of the so-deposited elastomeric material onto the core. Cutting means are also included for cutting away elastomeric material not deposited on the core. The core and elastomeric material deposited thereon are then turned over and the operation is repeated, whereby elastomeric tube means or the like are provided on the toroidal core.
