Beating-up arrangement for a wave-type weaving machine

A travelling wave-type weaving machine with reed teeth arranged along an axis and adapted to be pivoted about the said axis, the reed teeth abutting with some play on driven cam-like guide surfaces which on rotation cause pivoting movement of the reed teeth about the axis, the reed teeth producing movement of shuttles and the beating-up of the weft thread in one of the end positions of the said teeth, the said reed teeth forming in their entirety a wave-like periodic curve formed by the ends of the teeth moving towards their beat-up position, the said cam-like guide surfaces having first section and second section, said first section moving said shuttle and having a profiled guide surface that produces a substantial variation in the spacing of the guide surface from its axis of rotation, the first section merging into said second section that produces the beat-up position of the reed tooth, said second section having a profiled guide surface that immediately produces a linear variation of the spacing of the guide surface from its axis of rotation, which is less than the variation of the first section and extends to the immediate vicinity of the beat-up point so that an abrupt change in movement of the reed teeth from high speed in the first section for shuttle movement to lower speed in the second section is produced to prevent over-shooting of the reed teeth at the beat-up line.
