) 从输送带带尾向后,测量接头长度加允许修边长度的距离 FROM END OF BELT, MEASURE BACK LENGTH OF SPLICE PLUS TRIM ALLOWANCE.
b) 使用丁字尺划线USE SQUARE AND STRAIGHT EDGE TO DRAW MASTER LINE.
) 将丁字尺沿输送带对面的边放置,来检查主线。在每个边缘划分搭接长度,并检查两个对角线的长度是否相等。CHECK MASTER LINE BY LAYING SQUARE ALONG OPPOSITE EDGE. MARK OFF BIAS LENGTHS ON EACH EDGE AND CHECK THAT TWO DIAGONAL LENGTHS ARE EQUAL. 准备相对的带尾,向后折叠,重复上述工序,确保另一带尾上的斜线是在对边上。TO PREPARE OPPOSITE END, FOLD BELT BACK AND REPEAT PROCEDURE. MAKE SURE BIAS IS ON OPPOSITE EDGE ON OTHER END.
