ABSTRACT:
This relates to a system for reheating adhesive bonding an end unit to a can body under controlled conditions and then further telescoping the end unit relative to the can body to assure proper adhesive flow relative to the can body. An end unit has been previously applied to a can body and is bonded thereto by a hot melt adhesive which has partially set. The end unit is not in its fully telescoped position. The adhesive is reheated to a temperature wherein the adhesive has the desired fluidity, after which the adhesive is maintained at this temperature and the end unit is moved to its fully telescoped position with a bead of the adhesive flowing over and encapsulating the raw edge of the can body.
