摘要： A method and apparatus for automatically severing individual towels from a length of material comprising a plurality of terry towels. The method includes the steps of measuring slightly less than the supposed length of a towel, then activating a sensor that detects the edge of a cutting space by the change in thickness of the material. The sensor causes feeding of the material to stop with a cut-line at a cutting blade. The first edge of the material is held while a second sensor located the same edge at the opposite side of the material, and the cutting blade is moved with the sensor. The material is stretched to straighten the cut-line, and the cutting blade is caused to cut the material. The apparatus includes feed rolls to move the material, and an encoder measures the length. A roller at one edge of the material detects the change in thickness at one edge, and similar rollers detect the change in thickness at the opposite edge. The sensors are mounted on a single bracket that is pivoted at one sensor; and, the cutting blade is mounted to pivot and remain parallel to a line through the two sensors.

摘要： The side edges of a web of cloth are hemmed as the web moves from a supply along its length to a cutting station. The free end portion of the web of cloth is cut across its length with V-shaped notches cut at its side edges to form angled corners on the cut lengths of cloth. The cut lengths of cloth are moved through a U-shaped path with the cut ends extending along the path, and a connecting thread is attached to the cut lengths of cloth adjacent their cut ends and extends between adjacent lengths of cloth so as to connect together the cut lengths of cloth as they move sequentially through folding and sewing apparatus. The connecting thread extending between the adjacent cut lengths of cloth allows a preceding length to pull and guide a subsequent length through a hem folding device.
摘要翻译：当纸幅从供应沿其长度移动到切割站时，布料幅的侧边缘被卷绕。织物网的自由端在其长度上被切割，并在其侧边缘处切割V形凹口，以在布的切割长度上形成成角度的角。布的切割长度通过U形路径移动，切割端沿着路径延伸，并且连接线附接到与其切割端相邻的织物的切割长度，并在相邻长度的布之间延伸以连接在一起当布料依次通过折叠和缝合设备移动时，布的切割长度。在相邻切割长度的布之间延伸的连接螺纹允许先前的长度拉动并引导随后的长度通过折边装置。

摘要： A safety net for use with a lavatory to catch small items inadvertently dropped into the lavatory. The safety net includes a piece of net material sized to extend completely across the lavatory bowl in both directions and to allow the net material to conform somewhat to the bowl. Rather rigid end pieces are fixed to the net material to hold the net in place. The end pieces may be hinged to allow the safety net to be folded.
摘要翻译：盥洗室使用的一个安全网，无意中捡到小物品。安全网包括一块净材料，其尺寸设计成在两个方向上完全延伸穿过盥洗室碗，并允许网状材料稍微符合碗状。相当刚性的端部件固定在网状物上以将网状物固定到位。端件可以铰接以允许安全网折叠。
