Patent ID: 7386925

Claim:
A process for the production of textured filament strips made of a polymer material for artificial grass, comprising the steps of stretching or shrinking filament strips between two heating godets; texturing the filament strips in a stuffer box comprising a discharge end where the filament strips leave the stuffer box; drawing off the textured filament strips over a cooling godet comprising a guide groove and laying the textured filament strips in the guide groove of the cooling godet immediately after the texturing, wherein the filament strips are fed approximately radially to the cooling godet and wherein the step of laying of the textured filament strips in the guide groove is supported by an air nozzle arranged laterally on the stuffer box which directs an air jet at the discharge point of the stuffer box at an angle of approximately 45° to the longitudinal axis of the discharge end of the stuffer box; and spooling the textured filament strips.
