ABSTRACT:
A method is disclosed for the resilient spinwelding of two (thermoplastic) body portions to one another. The incorporation of resilient members between the prior art "hard surfaced" spinweld apparatus and the body portions to be welded together significantly decreases the spinweld time, and in the case of container/lid systems used for food packaging, increases the burst pressure of the container/lid.
