    • Sheet folding apparatus of the type in which the sheet is folded while it is being conveyed through said apparatus with a folding station at which one or more sets of crushing rolls (32, 33) are disposed so as to crush the intended inner face (15) of the sheet material along only one predetermined side of a longitudinally extending crease line of the sheet (1), and at which press rolls (25, 29) are disposed so as to oppose the action of said crushing rolls and to butt against the outside face of the sheet folded at the folding station on either side of a said crease line, whereby the sheet can be folded with consistant accuracy. Each crushing roll may have an angled peripheral face and be set at an appropriate angle by support members (30, 31) to crush into the intended inner face of the sheet on one pre-determined side of a crease line, and preferably two press rolls are associated with each crushing roll, one for each side of a crease line, the drive for the press rolls being taken via a drive arrangement (18, 20 to 24) from conveying means (11) for the sheet, and the press rolls being driven in unison via meshing gearing (26 to 28).
    • 其中片材被折叠的类型的片材折叠装置在通过所述装置被折叠的同时折叠站设置有一组或多组破碎辊(32,33),以便粉碎预期的内表面(15) )沿片材(1)的纵向延伸的折痕线的仅一个预定侧的片材材料,并且压榨辊(25,29)设置成与所述破碎辊的作用相对并且抵靠 在折叠站折叠的片材的外表面在所述折痕线的任一侧,由此片材可以一致地精确地折叠。 每个破碎辊可以具有成角度的外周面,并且通过支撑构件(30,31)以适当的角度设置成在折痕线的一个预定侧上挤压到片材的预期内表面,并且优选地两个压辊 与每个破碎辊相关联,一个用于折痕线的每一侧,用于压榨辊的驱动器经由用于片材的输送装置(11)的驱动装置(18,20至24)获取,压辊为 通过啮合齿轮传动(26至28)一致驱动。
