Paper wrapped foam cup and method of assembly

摘要

An apparatus for automatically assembling a wrapper (104) to a foam cup (102) to form a wrapped foam cup (100) comprises:
a rotating platen (210) having multiple carriers (226), with each carrier (226) sized to support a wrapper (104);
a heater for heating the wrapper (104) to a bonding temperature;
a rotating mandrel assembly (212) comprising multiple rotatable mandrels (214), with each mandrel (214) supporting a different cup;
wherein the rotating platen (210) and rotating mandrel assembly (212) are arranged relative to each other such that upon their relative indexed rotation a rotatable mandrel (214) is effectively rolled over the surface of the carrier (226) to effect the wrapping of a wrapper (104) on the carrier (226) about a cup (102) on the mandrel (214).
