Abstract
The cassette of the invention comprises a plastic tray having at one end an array of projecting curved fingers and an auxiliary member having an array of curved fingers, with the auxiliary member adapted to seat on the base so that the curved fingers of the base form a smooth curve with the curved fingers of the auxiliary member. Before the auxiliary member is seated on the base, a plurality of separator sheets to be carried thereby are secured to the base by means of holes which are threaded on the first curved fingers. The auxiliary member is then seated in place, and ultrasonic vibrations are applied to heat and fuse the separate fingers to form unitary continuous curved rings which hold the sheets in place.
