Texturing device and texturing method

A texturing method for producing crimped plastic filaments, the method comprises:

• blowing at least one plastic filament through a nozzle insert in a texturing nozzle in a conveying direction by a hot compressed air flow and crimping the at least one plastic filament in a filament guide slot tube adjoining the nozzle insert to form at least one crimped plastic filament;
• subsequently cooling the at least one crimped plastic filament by directing a counter air flow, which is at least partially directed counter to the hot compressed air flow and which is cooler than the hot compressed air flow, towards the at least one crimped plastic filament;
• directing the counter air flow onto the at least one crimped plastic filament by a counter air flow slot tube that is oriented in line with the filament guide slot tube and is coupled thereto, and pulling the at least one crimped plastic filament through the counter air flow slot tube by way of a pass-through nozzle that is downstream of the counter air flow slot tube in a conveying direction and that blows air in the conveying direction.
