METHOD AND DEVICE FOR APPLYING OVERCAPS TO AEROSOL CANS

摘要

A capping device and method for installing overcaps onto a plurality of aerosol cans moving on a manufacturing line is disclosed. The capping device (40) has a pressure plate (42) with a cap contact surface (82) on one side a nd a bearing surface (80) on an opposite side. The contact surface is oriented to face overcaps (48) that are rested on a plurality of aerosol cans (44) movin g past the pressure plate (42) on the manufacturing line. The contact surface is rotated about an axis so that an installation segment of the contact surface moves in concert with the plurality of aerosol cans. A pressure wheel (46) h as a rotatable circumferential surface (90) arranged to bear against a part of the pressure plate (42) to further bear the installation segment into contac t with the overcaps (48) of the plurality of aerosol cans. As the cans move pa st the pressure wheel and plate, the overcaps are installed on the aerosol cans by force applied via the installation segment of the contact surface that is moving along with the cans.
