ABSTRACT:
A prepositioning and delivering mechanism for heald shafts is either permanently or temporarily attached to a loom for guiding the heald shafts when a shaft change is to be made. The mechanism has a carrier carrying prepositioning mechanisms each including a rocking lever and a guide roller. These mechanisms are arranged along a longitudinal axis of a journal axle (18) with a spacing that corresponds to a spacing pitch between heald shaft guide frames. Each roller of the prepositioning mechanism is engageable with a respective heald shaft. At least one of the heald shaft guides is engaged with a drive for delivering or advancing of the shaft guides toward the prepositioned heald shafts.
