Abstract: A machine for winding thin metal ribbon continuously on spools comprising a fixed entry chute (1) to receive the ribbon, a pair of support rollers (3, 3′) with a dancing roller (4) between them to support and guide the ribbon delivered through said fixed entry chute (1). A thickness measuring gauge (6) is provided in the path of the ribbon for continuously monitoring the thickness of the ribbon, a snubber roller assembly (30) is provided for pressing the ribbon and a brush assembly (31) is provided for catching the ribbon.

Abstract: An apparatus for continuously annealing amorphous metal alloy cores with a closed magnetic path consists of a tunnel furnace having a bus bar connected sequentially to a DC power source. Switching is provided to simultaneously close and open electrical contacts provided on either end of the bus bar to ensure a continuous supply of power while loading or unloading jobs. The apparatus has a conveyer and loading and unloading mechanisms at the feeder end and discharge end of the furnace. The bus bar passes through the core window of the amorphous metal alloy core during the annealing process. The apparatus also consists of conventional trip mechanisms, heating and cooling mechanisms and mechanisms for gas flow through the furnace.
