The concept of a successful machine Beater drive and beater. A beater that operates exactly and without any play is fundamental to the production of high quality bobbin-lace. The beater is driven by a cylindrical flanged eccentric. The exact engagement of the cam by pairs of adjustable rollers at the top and bottom of the flange ensures precise blade guidance without any play. The difficult task of synchronizing the open and closed sets of blades is eliminated. Automatic shot down triggered by thread breaks or empty bobbins and overload safety clutch. The shutdown device scans each individual carrier and stops the machine by means of limit switches as soon as a thread breaks or a bobbin runs out of thread. If the gear ring in the carrier drive becomes stiff of jams, a safety clutch immediately disengages the drive from the gear ring and prevents any material damage.
