Precise installation of a seam clamp is crucial as failure to do so will lead to defects, compromising the quality of paper containers. Even experts spend 90-120 minutes, which comprises 4.7 percent-6.25 percent of the replacement and adjustment process on a paper container manufacturing machine. To overcome an undesirable replacement procedure, a composite seam clamp was devised. The objective of this paper is to enhance the quality of a seam of a paper container and reduce time replacing seam clamps. The composite seam clamp was designed based on the Guerin process. Silicon rubber, which can be used in the temperature range of the paper container manufacturing process (110-130 ° C), was selected. To validate performance of the steel and composite seam clamp, 13 error situations resulted from translation and rotating misalignment of seam clamps were set and simulated. Through FEM (Finite Element Method) simulation, this paper confirms that the composite seam clamp shows higher transmission of clamping pressure compared to steel seam clamps in error situations. The feasibility of the composite seam clamp was validated in reducing replacement time of seam clamps through on-site tests.
