Care for Selvage
The threads must be properly divided in the front reed so as to make a good clearance for the filling, which otherwise would “nib” up and make an unsightly selvage. Then again, a careful adjustment of the weight carried on the selvage warp must be made so as to accommodate it to the requisite tension of the filling as it is delivered from the shuttle, otherwise the edge rubber threads will be liable to chafe and cut off when strained out of proper alignment with the front reed. It will be observed in the draft that two rubber threads are used in each selvage, which is necessary in order to control the additional yarn used in the construction of the selvage.
