Cyclopedia of textile work : a general reference library on cotton, woolen and worsted yarn manufacture, weaving, designing, chemistry and dyeing, finishing, knitting, and allied subjects . cs are found withinthis comparatively small range of tension movement. Width of Seam. The adjustment for width of trimming or bitehas been made semi-automatic; that is, it is operative within certainpredetermined limits at the will of the operator, and while the ma-chine is in motion, This is accomplished in a very convenient mannerby means of a treadle connection to the trimmer adjusting arm, which 329 36 KNIT GOODS FINISHING when actuated serves to alter the position of the trimming parts inrelation to the line of needle punctures. This feature of the machine enables an operator to complete agarment with seams which vary in strength as required in differentparts of the fabric. For example, a seam which is made along theside of a sleeve or drawer leg will be stronger than one made acrossthe top or shoulder of a shirt, providing no change is made in themachine. In the first instance, the stitching is with the wale, orlengthwise of the fabric, where there is no tendency of the knitting. Fig. 19. Two-Thread Crochet Finish on Very Rough Edge. stitches to ravel out, so that a minimum width of seam or trim can beemployed. In seaming .across the top or shoulder, and around arm-holes orgussets, the stitching is laid either squarely or diagonally across theends of the wales, where the knitting loops are exposed and extremelyliable to unravel if not properly secured; therefore a wider seam isnecessary. When it is desired to use this width-changing feature ofthe machine a thumb-pin is inserted in one of a series of holes in thetrimmer-adjusting arm, back of a stationary stop, and when it isagainst the stop this pin is a limit for the narrow seam. Anotherthumb-pin placed in a hole in front of the stop, as far away as isnecessary, to give the required change, will be a limit for a wide seam.
