摘要： 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.
摘要翻译：根据本发明，提供了一种用于输送幅材的装置。该装置能够连续地拉伸纤维网，或者在跨机器方向上从卷筒纸连续释放拉伸力。该装置包括两对相对的带，其中每个带沿着环形路径行进。成对的皮带在跨机器方向上彼此发散或会聚。每对皮带包括彼此相邻的上皮带和下皮带。上和下皮带中的每一个具有接触腹板的非平面外表面。每个上带的非平面外表面在机器方向上行进时，沿其相邻的下带的非平面外表面沿预定距离连续地邻接。这产生至少一个压区，用于在输送纸幅时持续抓住纸幅。该装置还包括用于驱动皮带以便沿机器方向输送卷材的装置。

摘要： A disposable thermal pad includes a substantially planar laminate structure having a first side and a second side and a plurality of heat generating cells embedded between the first and the second sides. The plurality of heat generating cells each are spaced apart and fixedly attached to the laminate structure. The laminate structure provides oxygen permeability to each of the plurality of heat generating cells. Oxygen permeability is achieved entirely on the first side of the laminate structure. The disposable thermal pad is releasably attachable to an inside portion of a user's clothing. The disposable thermal pad is releasably attachable on its first side of the laminate structure so that the second side of the thermal pad may be placed directly against a user's body.
摘要翻译：一次性散热垫包括具有第一侧和第二侧的基本上平面的层压结构，以及嵌入在第一和第二侧之间的多个发热单元。多个发热单元各自间隔开并固定地附接到层压结构。层压结构为多个发热单元中的每一个提供氧气渗透性。氧气渗透性完全在层压结构的第一面上实现。一次性散热垫可释放地附接到使用者衣服的内部。一次性散热垫可释放地附接在其层压结构的第一侧上，使得散热垫的第二面可以直接放置在使用者的身体上。
