BLINDSTITCH SEWING MACHINE

摘要

In a blindstitch sewing machine adapted to selectively produce non-skip stitches or skip stitches whenever desired, adjustable means for determining the normal position of a rockable work support carrying a node former to enable the machine to properly provide either type of stitching in work of different thicknesses and foldability. Said adjustable means and members controlled thereby serve to readily and accurately determine the normal position of the work support and the extent of rocking movement imparted thereto in forming skip stitches. The adjustable means includes a rotatable knob, the turning of which to a given extent will always provide the same extent of adjustment of the work support about its supporting axis.
