Crosswise yarns are removed from each turn of the fabric strip at the folds to produce unbound sections of lengthwise yarns. A base fabric, having seaming loops along its widthwise edges, is disposed between the first and second fabric plies. The seaming loops extend outwardly between the unbound sections of the lengthwise yarns from between the first and second fabric plies.      The first and second fabric plies and the base fabric are laminated to one another by needling staple fiber batt material therethrough.

Filed: 1999-09-10
Abstract: A communications method, communications system, communications device, and server which confirm performance information of a receiver communications device without negotiating with the receiver communications device before sending data, and sends an image most suited to receiving capability of the receiver communications device. The sender reads out performance information of the receiver communications device stored typically in a server before sending data, and sends data after converting the format of data to be sent based on the performance information. The communications device communicates with the server and sends data in the form of electronic mail and TCP/IP communications. Since, image data is sent after converting its format to that best matched receiving capability of the receiver communications device, the receiver communications device can receive image data best suited to its performance.
