Air-supported laying roller for textile yarn |
摘要 |
A laying roller for textile yarns which, via a central air supply, supplies two air feed channels which are separated from each other. Each channel feeds air via a respective one of two porous sintered bearing bushings which are axially separated from each other. The air passing through the porous bushings builds up an air cushion for supporting a surrounding roller shell.
