摘要： A method and apparatus for cutting threads, particularly threads formed of mineral substances such as glass, are disclosed. A rotating drum carrying a plurality of radially extending cutting blades operates in conjunction with a rotating support drum which carries and supports the thread for cutting by the cutting blades. Ejector elements carried by the cutting drum and positioned in the spaces between the cutting blades are urged radially outwardly by centrifugal force and compress the thread against the surface of the support drum. The ejector elements then serve to strip cut sections of the thread from between the blades as the cutting blades move away from the support drum. Compressed air is supplied to the spaces between the cutting blades to remove waste material resulting from the cutting operation.

摘要： Process and apparatus for cutting continuous strand or roving, particular strands of mineral material such as glass, into short lengths is disclosed. The apparatus employs a rotatable drum equipped with a large number of radially disposed cutting blades, the drum cooperates with a supporting device for supporting the strand as it is cut. Ejector bars are maintained in position on the drum between adjacent cutting blades by elastic mounting members that receive the ends of the ejector bars. The elastic mounting members cause the ejector bars to compress the strand against the support drum as the strand is being cut and, in conjunction with centrifugal force arising from rotation of the drum, to eject the cut pieces of strand from the cutting drum.
