<p>Machine for the continuous manufacture of circular waveguides adapted to convey TE01 mode electromagnetic waves. The machine comprises a wire winder for winding an insulated metal wire onto a spindle, to provide adjacent turns of the wire winding in peripheral contact with each other a ribbon winder for armoring the wire winding with a ribbon winding and a capstan driver for supporting and centering the spindle and allowing the winding to advance along the spindle. For making the winding fully regular and uniform in spite of variations in the wire diameter, a tensioning device is provided, so that the tension of the wire at the point of winding must be held quite constant. This wire tension at the point of winding depends on the tension of the supplied wire at the winding point of origin and on the reaction of the wound portion, which has already been made. The tension of the supplied wire is made constant by means of an adjustable wire tensioning device which is located on the machine axis and which pulls the wire in a path to describe a cone. Because of this arrangement of the tensioning device, the spindle cannot be mounted onto the machine frame through any supporting members which would interfere or stand in the course or path of the wire. The spindle is immobilized by means of a magnetic clutch. The reaction of the wound portion is made substantially constant by maintaining under compression that portion of the winding which is located between the wire winder and the capstan driver.</p> |
