    • 摘要:即使减少接缝角部的接缝部的曲率半径,也能够确保高密封性的方形,能够减小锪孔深度,尺寸减小,密封性和存储效率优异的方法和方法 用于双重缝合方形罐的装置。 第二接缝辊(55)由用于第二接缝的模型凸轮引导,具有用于第二接缝的模型凸轮表面,其形成为使其从模型凸轮表面膨胀形成,以在角接缝部分(5)处首先向外接合, 。 因此,角接缝部(5)的接缝形状形成为使角接缝部的中心处的接缝宽度大于线状密封部(4)的接缝宽度,向外膨胀 以吸收角部缝合部分处的片材厚度增加。 此外,缝合壁(6)形成为倾斜的接缝形状,使得可以确保盖钩(8)与规定量的身体钩(10)的重叠,而不允许盖钩(8) 从身体钩(10)落下,以保持优异的密封能力。
