    • A packaging apparatus includes a pair of rolls forming a nip through which two web portions are passed with an item to be packaged between the web portions. The rolls include resiliently compliant roll portions that deform to accommodate the thickness of the item, and the roll portions press the web portions to seal them together in peripheral regions surrounding the item and to center the item between the webs in the thickness direction. The apparatus also includes side seal devices that traverse inwardly toward the item to seal the webs together close to the item's opposite side edges to prevent the item from laterally shifting. The web portions may have cohesive disposed on their facing surfaces such that the web portions adhere to each other with pressure but tend not to adhere to the packaged item or other surfaces.
    • 一种包装设备包括一对辊,其形成一个辊隙,两个卷筒纸部分通过该卷筒纸部分之间被包装的物品通过。 辊包括弹性柔顺的辊部分,其变形以适应物品的厚度,并且辊部分压缩幅材部分以将它们一起密封在围绕物品的周边区域中,并使物品在厚度方向上在纸幅之间居中。 该设备还包括侧向密封装置,其朝向物品向内横过,以将幅材密封在靠近物品的相对侧边缘的位置,以防止物品横向移动。 纤维网部分可以具有粘合性,其布置在其相对的表面上,使得幅材部分以压力彼此粘合,但是倾向于不粘附到包装物品或其它表面。
