    • A method is disclosed by which an air pressure different from the atmospheric pressure is generated and distributed to a sheet of paper in a sheet feed printing machine, comprising the step of generating a work-pressure in means arranged to discharge the work-pressure to the sheet and thereby to effectuate or control the transport of the sheet in the printing machine. The method is characterized through a continuous adjustment of the work-pressure that is discharged from each singular discharge means or from each singular set of discharge means to a work- pressure which is adapted to the subject sheet and/ or the subject process in the printing machine, and which is operative for control or transport, in response to detecting at all times the work-pressure discharged from each singular discharge means or from each singular set of discharge means. In analogy herewith an assembly in a sheet feed printing machine is disclosed, the assembly comprising means that are movably arranged in the printing machine and arranged for discharging to a sheet of paper a pressure that is different from the atmospheric pressure, and by means of the discharged work-pressure effectuates or controls the transport of the sheet in the printing machine. The assembly is characterized in that the discharge means comprises means for continuous adjustment of the discharged work-pressure to a work-pressure which is adapted to the subject sheet and/or the subject process in the printing machine, and which is operative for control or transport, in response to detecting at all times the work-pressure being discharged from each singular discharge means, or from each singular set of discharge means.

    • A method of and apparatus for separation from a stack of sheets (150) a block of a predetermined number of sheets (G), the method including moving the stack in a forward direction (F), directing an air stream (24) across one corner of the forward portion of the stack to spread the corners apart, sensing and counting the number of spread sheet corners that pass a predetermined location, and separating the group of sheets from the remainder of the stack when the sensed and counted sheets reach a predetermined number. Further directing a thin plane of air (26) toward the corner and center of the sheets at said location to cause a greater space between the sheets in the group and the next sheet in the stack. Also, vacuum nozzles (164, 166) are provided to remove unwanted air from above and below the stack and group. With the group so formed, separation includes imparting lateral force on the group edges.
    • 一种用于从堆叠的片材(150)分离预定数量的片材(G)的块的方法和装置,所述方法包括沿正向(F)移动所述堆叠,将空气流(24)引导到一个 叠层的前部的角部将角部分开,感测并计数通过预定位置的扩展片角落的数量,并且当感测和计数的片材达到预定的片材时,将该组片材与堆叠的其余部分分离 数。 进一步将薄的空气平面(26)引导到所述位置处的片材的角部和中心,以在组中的片材和叠片中的下一个片材之间产生更大的空间。 而且,提供真空喷嘴(164,166)以从堆叠和组的上方和下方去除不需要的空气。 在组合如此形成的情况下,分离包括在组边缘上施加横向力。
