A cylindrical shaped mandrel is used as a support inside the sleeve of tubular knit fabric, for maintaining the cylindrical shape of the fabric during extraction and compacting processes. Encasing the fabric and the mandrel is a larger diameter cylindrical ring member which presses the fabric against the mandrel in order to perform the extraction and compaction processes. The ring member extends for some distance in the longitudinal direction of travel of the knit fabric and contains a mechanism, such as a detent, for retaining the mandrel in place. A rope of tubular fabric is conveyed into the mandrel/ring assembly by an endless conveyor or belt made from a flexible material such as rubber. As the fabric is fed onto the mandrel, the belt forms a cylindrical sleeve around the fabric and the mandrel and is compressed by the cylindrical ring. |
