ABSTRACT:
By means of the method proposed the joining of a cap and a body of a capsule used to enclose medicines, with the open end of the body already inserted in the cap, is achieved by directing a flow of hot compressed fluid, progressively on a circular portion of the cap overlapping a relative underlying circular portion of the body, so as to affect the entire circumference of the circular portion of the cap; the resulting seal between the said portions prevents separation, without breaking, of the cap or the body.
