    摘要： The invention relates to a method of creasing sheets (12) by using a creasing tool (14, 20, 21) cooperating with a counter element (22, 23), comprising the following steps: a creasing plate blank (24′) is provided with at least one creasing projection (26) by plastically deforming the material of the blank (24′) so as to form a creasing plate (24), the creasing plate (24) is mounted to a creasing tool (14, 20, 21), sheets (12) to be provided with at least one crease are advanced through a gap between the creasing tool (14, 20, 21) and the counter element (22, 23).

    摘要： A conveyor of a cardboard-folding station receives a cardboard blank having a first portion, first and second lateral closing walls hinged thereto and facing upstream and downstream, respectively, an upper closing wall hinged to the second lateral closing wall and facing downstream, a third and a fourth lateral closing wall hinged and partly raised with respect to the first portion and projecting from sides of the conveyor. An article rests on the first portion, with four flanks or the article respectively facing the four lateral closing walls of the blank. At a first folding zone the third and fourth lateral closing walls are folded to cover the third and the fourth flanks of the article, and at a second folding zone the second lateral closing wall and the upper closing wall are folded to cover the article's second flank and its upper face.

    摘要： Apparatus for folding collapsible box blanks transversely to a feed direction in which blanks are fed to strip-like tools each pivoted about an axis above a conveyor on which the blanks are supported, and transverse to the feed direction and having a sliding surface forming a ramp which rises from the conveyor in the feed direction downstream of the said axis. Unlike known apparatus, a movable depressor is provided to hold down the blank in the vicinity of the tools and further the folding tools are not driven. In the embodiments described they are restrained by a spring loaded locking device, against free pivotal movement until the torque applied to the tool during feeding of the blank, exceeds a predetermined minimum. In one embodiment, the folding tools are movable in the same direction as the conveyor but at a higher velocity, the resultant relative velocity determining the feed direction.

    摘要翻译： 用于折叠可折叠盒坯料的装置，其横向于进料方向，其中坯料被供给到带状工具，其各自围绕其上支撑有坯料的传送带上方的轴线枢转，并且横向于进给方向并且具有形成斜坡的滑动表面 其在所述轴线的下游的进给方向上从所述输送机上升。 与已知的装置不同，提供了一个可动的压紧器来压住工具附近的坯件，并且还可以不折叠工具。 在所描述的实施例中，它们被弹簧加载的锁定装置约束，抵抗自由枢转运动，直到在坯料进给期间施加到工具上的扭矩超过预定的最小值。 在一个实施例中，折叠工具可沿着与输送机相同的方向移动，但是以更高的速度运动，所得到的相对速度确定进给方向。
