摘要： To prevent printing of imperfect copy, by a printing machine having a lifter-type inker, which is caused by cyclically recurring rotary oscillations or vibrations, the braking torque introduced upon contact of a lifter roller (3) with the first milling and distribution roller (4) of the inker is prevented from propagating through the gearing drive of the respective inker rollers. To prevent such propagation, the first milling and distributing roller (4) is yieldingly driven at machine speed, for example by frictional drive, transmitted through an elastic surface (6) of a "soft" roller in frictional drive engagement with the first milling and distributing roller (4) as well as with a positively driven subsequent milling and distributing roller (7), or a circumferentially resilient yielding coupling (13) is interposed between the drive shaft element (8) for the first milling and distibuting roller and a positive gear drive (10, 11, 12). Preferably, the inertia of the first milling and distributing roller is high with respect to that of the lifter roller (3), and is, for example, enhanced by a fly-wheel (4 a).

摘要： To permit essentially automatic control of roll changing to change between an old roll and a replacement roll of printing machine paper, adhesive is applied to the old roll, at predetermined locations, as the old roll runs off, and the now sticky surface is engaged against the beginning portion from the new roll, the old roll then being severed within the range of the still sticky portion to ensure complete adhesion of substrate from the old roll on the substrate of the new roll. Excess adhesive which is not covered by substrate from a new roll is deactivated by a deactivating element (7) positioned in advance of any deflection roller to prevent accumulation of adhesive on any elements of the roll changer of the printing machine.
摘要翻译：为了允许基本上自动控制滚筒更换以在旧卷和更换卷筒之间改变印刷机纸，当旧卷滚下时，粘合剂在预定位置施加到旧卷，并且现在粘性表面与来自新卷的开始部分，旧辊然后在仍然粘性部分的范围内被切断，以确保基材从旧辊在新辊的基材上的完全粘合。未被新卷筒覆盖的过量粘合剂由位于任何偏转辊之前的钝化元件（7）去活化，以防止粘合剂在印刷机的卷纸更换器的任何元件上堆积。

摘要： To prepare an initial portion (41) on a replacement roll (4) of a substrate web, for example a printing paper web, for flying pasting, the new roll (4) is rotatably supported in apredetermined position. An adhesive application and cutter structure (5) is then placed in operative association with the roll. An initial portion (41) of the web is rolled off from the new roll, positioned on the support plate, and, in one operating step, an end, which may be jagged, is cut off and, inwardly of the cut edge (42), a perforating or tear-off line (43) is formed, to leave, between the cut edge and the tear-off line, a tear-off section (44). The web can then be repositioned on the plate (6) and a connecting adhesive (19) is applied to the upper side of the web, for subsequent flying pasting against a moving expiring web, for example, as well as a holding adhesive, applied in the inside of the tear-off section (44), so that the end portion (41) is securely attached to the roll. Preferably, the cutter and perforating blades are located on a single support block; and the adhesive applicators, likewise, are retained on a common support structure, which may be coupled with the blade support structure, for conjoint movement across the web.
