【発明の名称】二対の対向する非平坦ベルトを用いてウェブを連続的に伸張またはウェブから伸張力を連続的に解放させる装置
Document Type and Number:
Japanese Patent JPH10501190
Kind Code:
A
Abstract:
In accordance with the present invention there is provided an apparatus for conveying a web. The apparatus is able to continuously stretch the web or continuously release the stretching forces from a web in the cross-machine direction. The apparatus includes two pairs of opposing belts wherein each belt travels along an endless path. The pairs of belts diverge or converge from each other in the cross-machine direction. Each pair of belts comprises an upper belt and a lower belt which are adjacent to each other. Each of the upper and lower belts has a non-planar outer surface which contacts the web. The non-planar outer surfaces of each upper belt continuously abuts the non-planar outer surface of its adjacent lower belt along a predetermined distance when traveling in the machine direction. This creates at least one nip for continuously gripping the web while it is being conveyed. The apparatus also includes a means for driving the belts so as to convey the web in the machine direction.
