摘要

The beat-up mechanism of a loom with exciters for vibrating motion of the reed is presented. With the placing of exciters at regular distances across the width of the reed, certain differences can be observed in the amplitudes of the vibratory motion of individual blades. Undercutting is proposed here as a method of reducing these differences. The permissible distance between the exciters was determined taking into account the undercut reed. The undulation of the reed in the process of thickening of the wefts is shown to be a consequence of undercutting. For a distance between the exciters of L = 200 mm and relative depth of the undercut h(0)/h = 0.8, differences in the amplitudes of individual blades do not exceed 10%.
