Abstract
During sizing division, a rod grid (19) comprising lease rods (7a to 7e) is used for the formation of a shed, the rod grid being able to be raised with the aid of a lifting device (22) from a middle position into an upper operating position (O). A lower operating position (U) is limited by a mechanical stop (21), the individual lease rods being sequentially permitted to fall from the upper operating position into the lower operating position by a locking device. At the same time, a yarn shed is opened for each respective cross cord (12) insertion, the yarn shed lying in the same position for each yarn group. The opening angle .beta. of the yarn shed can, in addition, be altered within specific limits. Automation of cross cord insertion is facilitated by this type of shed formation.
