摘要： A continuous web of printed paper is cut by a cutting cylinder into discrete sheets on being wrapped around part of a folding cylinder. The folding cylinder has sets of the folding blade in the cavity each aligned parallel to the cylinder axis and all arranged at constant circumferential spacings. Each folding blade is movable radially of the folding cylinder for pushing one sheet of printed paper off the cylinder surface in the middle of the sheet. Disposed opposite the folding cylinder, a jaw cylinder has cavities opening to its surface at constant circumferential spacings, each for receiving the midpart of the sheet being pushed by the folding blade in the cavity. Each cavity has a movable jaw arranged therein for pivotal motion toward and away from a fixed jaw in order to crease the sheet. An indentation is formed in the fixed jaw so as to be in opposed relationship to the insert part of the folding blade on the folding cylinder in the cavity as the folding blade is inserted in the cavity with the sheet.
摘要翻译：打印纸的连续卷筒纸被切割圆筒切割成折叠圆筒的一部分周围的分立片材。折叠圆筒具有腔体中的折叠刀片组，其平行于圆柱体轴线对准，并且都以恒定的圆周间隔排列。每个折叠刀片可在折叠圆柱体的径向上移动，用于将一张打印的纸张从片材中间的圆柱表面推出。在折叠圆筒的对面设置有一个凹口圆筒，其腔体以恒定的圆周间隔开口到其表面，每个孔用于容纳由该折叠刀片在空腔中推动的薄片的中间部分。每个空腔具有布置在其中的活动夹爪，用于朝向和远离固定夹爪的枢转运动，以便折叠片材。当折叠刀片与片材插入空腔中时，在固定夹爪中形成凹陷，以便与空腔中的折叠圆筒上的折叠刀片的插入部分相对置。
