    摘要: Stretching apparatus for synthetic filaments is provided with plates (5.1 and 5.2) located in a stretching bath S in spaced apart facing relation to one another to provide a space between which the filaments are drawn along a path. The plates are structured in accordance with the invention (as shown in FIGS. 7 to 16a) so that vibration of the yarn during the passage through the stretching bath is suppressed. At least one of the plates is penetrated by holes which open at the plate surface facing the yarn path.

    摘要: A drawing roller unit is constructed with a godet and an electric motor mounted on a common shaft. A passage is provided throughout the unit to convey a non-flammable scavenging gas through the motor and the godet to reduce the risk of explosion due to sparking by the electric motor and/or other electrical parts of the drawing roller. The gas introduced can leave the unit only through a narrow gap. The pressure of the gas is consequently above atmosphere pressure and prevents the entrance of air.
