The study considers the impulse-momentum method for the analysis of the narrow loom with impulsive force and discontinuous velocities. The system equation of motion is analyzed to determine the main body velocities used for the system variables without introducing rotational coordinates or the turning effect of the system follower on the beater. Discontinuities in the velocity are observed when an impact force results from the beat-up action of the beater on the weft-yarn. Formulation between the velocity jump and displacement is presented for the system response. The impact phenomenon is characterized by the rise in the system velocity resulting from the vibration propagation through the system. The velocity is observed to increase as the system displacement response increases. This is typical of a high speed mechanism of this type mostly used in the textile industry if not controlled.
