An apparatus for the continuous crimping of thermoplastic threads has at least one crimping nozzle with a feed channel and a nozzle orifice and at least one pair of lateral guide means, e.g. needle rows, arranged around the circumference of a plug feed roller wherein, in an apparatus in which several threads are crimped in parallel, several axially spaced guide means pairs are used on the same feed roller, and in order to prevent disturbing transverse flows so as to render the aerodynamic conditions uniform during plug formation in the vicinity of the crimping nozzle orifice and for easy handling the plug feed roller, the guide means are axially protected against one another and against the outside by protective rings which have an identical or larger external diameter than the pair of guide means.
