ABSTRACT:
A circular knitting machine. The apparatus includes a generally conventional circular knitting element for forming a tubular knit fabric. A tension-controlled roll take-up assembly is located downstream from the circular knitting element for receiving the tubular knit fabric and forming a fabric roll from the tubular knit fabric while, at the same time, maintaining substantially constant tension on the tubular knit fabric being formed by the circular knitting element. This allows very large fabric rolls to be formed. In the preferred embodiment, the circular knitting machine includes a tension-controlled umbrella storage feed mounting ring adjacent to the circular knitting element for supplying a plurality of yarn ends to the circular knitting element for forming the tubular knitted fabric. The umbrella storage feed mounting ring permits an operator to attend to most machine functions without the need for a ladder or catwalk. In addition, the location of the tension control elements along the perimeter of the umbrella storage feed mounting ring provides an additional yarn reservoir which helps prevent fabric defects by providing additional time to stop the machine before, for example, a broken end of yarn enters the machine.
