Patent ID: 7060142

Claim:
A sealing apparatus, comprising: a first holding member having a first sealing abutment surface; and a second holding member having a second sealing abutment surface; said first and second holding members being adapted to hold a flexible workpiece between the first and the second sealing abutment surfaces for sealing; the first holding member being disposed on a periphery of a rotor with the first sealing abutment surface directed radially outward, the second holding member being supported by a support with the second sealing abutment surface directed to face the first sealing abutment surface; wherein the apparatus further comprises rotational driving means for driving the rotor to rotate; and reciprocating driving means for driving the support and moving the second sealing abutment surface in reciprocating motion along a part of an oibital trajectory of the first sealing abutment surface, thereby enabling holding of the workpiece between the first and the second sealing abutment surfaces for sealing when the second holding member moves in the same direction as the first holding member.
