A process for introducing one or more threads into a texturizing nozzle, in which the texturizing nozzle, together with the inlet member, is first brought into a position in which the thread is led transversely past and in the immediate vicinity of the texturizing nozzle, the thread is sucked against the nozzle with the orifice of the inlet member enlarged, immediately after being sucked against the texturizing nozzle the thread is cut beyond the nozzle so that the cut end is sucked back into the nozzle, the suction supply required for the sucking-in is replaced by pressurized fluid texturizing medium, and the cross-section of the inlet orifice of the texturizing device is reduced to a value advantageous for steady state operation. An apparatus for carrying out the above process, comprising a pivotable texturizing nozzle with an inlet member of variable cross-section, and a suction device which permits the pressure to be reduced, relative to atmospheric pressure, at the inlet member of the texturizing nozzle, is also disclosed.

The generation of tape tension, based on the capacity for elastic flow of elastomeric incompressible layers, in a tape transport apparatus employing at least one capstan in contact with supply and take-up reels of tape is accomplished by producing a higher compressive force at the point of contact between the take-up reel and the resiliently deformable peripheral portion of the capstan than at the point of contact between the supply reel and the capstan. The difference in compressive forces is brought about by an additional force which is produced by means of a drivable rotating body and is transmitted to the tape reel carriers by means of a cable which is guided over this rotating body.
