    • The invention is directed to method and apparatus for wrapping pads. A web of flexible wrapping material is adapted to be pulled in tension over a forming device. The forming device has first and second folding members having angled folding edges adapted for contact by respective opposite side margins of the web as the web is pulled past the folding edges. A web guide guides the web toward the folding edges. An opening between the web guide and the folding edges is adapted to be spanned by a central portion of the web as the web is pulled past the forming device. A series of pads are conveyed by a conveyor, one after another, and placed on the web as it is pulled past the forming device so that the pads move with the web over the opening and past the folding edges of the forming device. A surface applies a force to the pads to force the pads against the central portion of the web as the pads move across said opening. The force is sufficient to cup the web to position the pads for travel past the first and second folding members with concurrent folding of the side margins of the web by respective folding edges to form a tube around the pads.
    • 本发明涉及包装垫的方法和装置。 柔性包裹材料的卷材适于在成形装置上拉伸拉伸。 成形装置具有第一和第二折叠构件,其具有成角度的折叠边缘,该折叠边缘适于在幅材被拉过折叠边缘时通过幅材的相应的相对侧边缘接触。 卷筒纸导轨将卷筒纸朝向折叠边缘引导。 当腹板引导件和折叠边缘之间的开口被拉动穿过成形装置时,该幅材引导件和折叠边缘之间的开口适合于幅材的中心部分。 一系列垫片由输送机一个接一个地输送,并且当它被拉过成形装置时放置在卷筒纸上,使得垫片随纸幅移动而越过开口并经过成形装置的折叠边缘。 当衬垫移动穿过所述开口时,表面向衬垫施加力以迫使垫抵靠在幅材的中心部分。 该力足以将纸幅定位以便经过第一和第二折叠构件行进,以通过相应的折叠边缘同时折叠幅材的侧边缘,以形成围绕垫的管。

    • Methods of portioning by weight a plurality of articles of randomly varying weight. An array of articles is randomly assembled and then individual weights sensed. Some of these articles are then selected, to add up to the desired total weight. A preliminary step can be used wherein articles of unknown weight are first assembled to form a preliminary weight portion known to be short of the desired final weight, and then articles of known weight are added to reach the final target weight. An apparatus for accomplishing the methods comprises an array of scales dischargable upon signal from a control system, means for resupplying the scales, and a control system for sensing, storing and analyzing the weights of articles in the scales, and causing the proper scales to be discharged.
    • 按重量分配多个随机变化重量的制品的方法。 随机组装一系列物品,然后检测个体重量。 然后选择这些文章中的一些,以加起来达到所需的总重量。 可以使用初步步骤,其中首先组装未知重量的制品以形成已知缺少所需最终重量的预备重量部分,然后加入已知重量的物品以达到最终目标重量。 一种用于完成该方法的装置,包括可根据来自控制系统的信号放出的标尺阵列,用于重新供应秤的装置,以及用于感测,存储和分析秤中物品重量的控制系统, 出院
