Abstract
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.
