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.

Apparatus for forming a portion of a tube on a toroidal core from elastomeric sheet material comprising:
- frame means;
- a toroidal core support means operatively associated with the frame means for supporting the toroidal core;
- means operatively associated with the frame means for positioning and supporting a sheet of elastomeric material adjacent the so-supported core along one side of the so-supported core;
- means for depositing elastomeric material of the sheet thereof onto the so-supported toroidal core along a continuous path thereof;
- and
- means for selectively applying force to an annular portion of the elastomeric material associated with the core to urge an annular portion of elastomeric material against the so-supporting core.
Apparatus for forming a portion of a tube on a toroidal core from elastomeric sheet material comprising:
- frame means;
- a toroidal core;
- support means operatively associated with the frame means for supporting the toroidal core;
- means operatively associated with frame means for positioning and supporting a sheet of elastomeric material adjacent the so-supported core along one side of the so-supported core;
- means for depositing elastomeric material of the sheet thereof onto the so-supported toroidal core along a continuous path thereof;
- means for selectively applying force to a first annular portion of the elastomeric material associated with the core comprising a first elastomeric ring, said first elastomeric ring having a continuous annular surface, and means for selectively moving the continuous annular surface of said first elastomeric ring into contact with a portion of the elastomeric material associated with the core, and selectively moving said continuous annular surface of said first elastomeric ring away from the portion of elastomeric material associated with the core;
- and
- means for selectively applying force to a second annular portion of elastomeric material associated with the core comprising a second elastomeric ring, said second elastomeric ring having a continuous annular surface, and means for selectively moving the continuous annular surface of said second elastomeric ring into contact with another portion of the elastomeric material associated with the core, and selectively moving said continuous annular surface of said second elastomeric ring away from another portion of elastomeric material associated with the core.
