    Abstract: An apparatus and method for forming longitudinal folds in a series of webs while interfolding the webs into a continuously moving stack. The webs are interfolded through the use of a plurality of folding devices which are positioned along the path of the stack and are effective to successively turn a longitudinally extending edge portion of each web over the stack. A single folding device is provided for each pair of webs to be interfolded, and the webs in each pair are received by the corresponding folding device at spaced locations along its length. The folding devices are of identical construction and include longitudinal guide elements for preventing the turning over of an edge portion of the web received at the first location until after it has moved past the succeeding location. An angularly disposed guide element on each folding device thereafter turns the edge portion over the stack. An edge portion of the second web received by the folding device is not turned over until the web passes the first location on the immediately succeeding folding device and is received by an additional angularly disposed guide element thereon.

    Abstract translation: 一种用于在一系列腹板中形成纵向折叠的装置和方法,同时将腹板折叠成连续移动的叠层。 通过使用沿着堆叠路径定位的多个折叠装置,网状物被折叠,并且有效地连续地将每个纤维网的纵向延伸的边缘部分转过堆叠。 为每对腹板提供单一的折叠装置以进行交织,每对中的腹板在相应的折叠装置沿着其长度的间隔位置被接收。 折叠装置具有相同的结构,并且包括纵向引导元件,用于防止在第一位置处接收到的幅材的边缘部分的翻转,直到其移动通过后续位置。 然后,每个折叠装置上的角度设置的导向元件将边缘部分转过堆叠。 由折叠装置接收的第二幅材的边缘部分不会翻转,直到幅材通过紧接着的折叠装置上的第一位置并且被其上的另外的角度布置的引导元件接收。

    Abstract: IN AN APPARATUS FOR A METHOD OF DEFIBRATING A WEB OF WOOD PULP, THE WEB IS CONDITIONED BY A UNIFORM SPRAY OF LIQUID IMPINGING ON THE WEB IN A UNIFORM PATTERN AND WITH A UNIFORM DENSITY ACROSS THE FULL WIDTH OF THE WEB. THE SPRAY MAY BE A MIXTURE OF MINERAL OIL AND WATER AND MAY BE GENERATED BY ROTATING A DIP ROLLER INTO A TANK OF THE LIQUID TO LIFT A FILM OF LIQUID TO A ROTATING BRUSH ROLLER. THE ROTATIONAL SPEED OF THE BRUSH ROLLER IS HELD CONSTANT AND THE ROTATIONAL SPEED OF THE DIP ROLLER IS VARIED

    IN ACCORDANCE WITH THE WEB TRAVEL SPEED TO PROVIDE A UNIFORM DENSITY OF SPRAY, PREFERABLY ON BOTH SIDES OF THE WEB. THE LIQUID IN THE TANKS MAY BE HELD AT A CONSTANT LEVEL BY A CONTROLLED SUPPLY MEANS.

    Abstract: A series of flat articles are advanced along a path at regular intervals and are folded by continuously traveling fingers which engage an article intermediate its ends and fold the same. The fingers advance the articles to a station at which the folded articles are deposited as the fingers automatically withdraw from the folds. The folded articles may be abutted seriatim into a stack within an accumulator in the form of a conveyor traveling a speed considerably slower than the speed of the traveling fingers.
