ABSTRACT:
In an apparatus for sewing articles, such as sewing a slide fastener chain to an opening in an article, stitching of thread to an article is initiated by a manual control and is terminated by an automatic control in response to the sensing of a terminal point, such as the terminal point of an opening, on the article.
Article guiding facilities urge folded edge portions of an article toward each other by spring biased members on folding plates.
A scroll for receiving and guiding a folded edge portion of an article has an adjustable channel.
A linear motion apparatus, such as a dual needle holding mechanism, employs a linear motor driving a camming member which engages a locking member on a movable member to move the movable member to a selected position and to operate the locking member.
