The subject of the research is the process of winding the warp threads with the weaver beam and ensure the stability of the thread tension on looms.In work analyzes factors influencing a static component of the tension of the warp threads and is a variable at change the diameter of the winding threads on a weaving beam.The purpose of work is development of a method of calculation of change of a tension the warp 3 Piece King Storage Bed threads on projectile weaving machine type STB during for unwound all warp threads with the weaver beam.The proposed method of calculation to determine the tension of the warp threads depending on the winding diameter of the warp threads on a beam.Results of work can be used to optimize the adjustment parameters of warp let-off regulators on projectile weaving machine type STB to stabilize the tension of the warp threads, increase of Chicken Rotisserie Element labor and equipment productivity and improvement of quality of the developed fabrics.
