    • A printing plate sucker capable of stably suction-adhering and sheet-feeding both a printing plate and a protective sheet simultaneously without causing wrinkling at the protective sheet during the suction-adherence and sheet-feeding. The sucker is structured by a main body portion formed of a stiff body, a skirt portion formed of a resilient body, and a spring. When a moment from a printing plate acts on the sucker during sheet-feeding, the spring resiliently deforms. Thus, the main body portion is displaced (inclined) in the moment application direction, effective weight on the sucker is reduced, and a state in which a reduced moment acts on the sucker is achieved (the moment is substantially absorbed). Furthermore, the spring which redirects the moment is structured separately from the main body portion and skirt portion. Therefore, the sucker will not be deformed, an interleaf sheet will not be hoistingly deformed, and wrinkling will not occur.
    • 一种印版吸盘,能够在吸附粘合和片材供给期间同时稳定地吸附粘合和片材供给印刷版和保护片而不会在保护片上产生褶皱。 吸盘由由刚体形成的主体部分,由弹性体形成的裙部和弹簧构成。 当在片材进给期间来自印版的片刻作用在吸盘上时,弹簧弹性变形。 因此,主体部分在力矩施加方向上移位(倾斜),减小了吸盘上的有效重量,并且实现了减小的力矩作用在吸盘上的状态(该力矩基本上被吸收)。 此外,重新定向的弹簧与主体部分和裙部分离开地构成。 因此,吸盘不会发生变形,中间板不会变形,不会起皱。
