Abstract
Open molds for forming molded packings are moved sequentially to a series of work stations. The work stations include a preparation station for preparing the molds with a separator sheet or other release agent and a clamping station for covering the molds to contain foam material within the molds during cure. The foam material is dispensed into the molds as the molds are moved from the preparation station to the clamping station. The molds may be inverted as they are moved from the clamping station to an ejection station such that removal of the molded packings is facilitated by gravity. The sequence and duration of the various operations are controlled to provide automatic manufacture of the molded packings. A unique system for delivering a thin sheet to a molding machine or to other types of sheet processing machines is also disclosed.
