Abstract

A method of making the roll film stock cartridge described in the specification consisting of cover and base parts in plastic material, comprising assembling the plastic parts to be welded with small integrated projections spaced apart from each other at the edge of at least one of the parts, in contact with the corresponding edge of the other part, and apply a unique ultrasonic welding bell to the parts, in order to ultrasonically weld them together in a single operation with ultrasonic energy that is directed through said projections .
