Abstract

Method and apparatus is provided for the inline string-up, in automatic fashion, of a rapidly advancing filament, particularly a glassy alloy strip, from a high speed continuous casting operation onto a rotating winding wheel. The leading segment of the advancing filament is passed into the nip of two counterrotating brush rollers 15 having a peripheral velocity exceeding that of the advancing filament to produce a sliding frictional tensioning of the filament. The brush rollers and engaged filament are then moved over the rotating winding wheel 28 to lay a segment of the advancing filament onto the rotating winding surface. A cut-and-grip device 8 associated with the winder is then actuated to cut the filament at the winding surface and to secure the filament onto the winder, whereupon winding of the advancing filament proceeds.
