摘要:
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.

A throat plate holding the feed dog of a twin-needle sewing machine has formed therein a pair of parallel spaced guide channels for slidably accommodating respective scoop-carrying edges of the pair of concealed fastener stringer tapes as they are stitched onto a fabric. When seen in a cross section, the guide channels diverge downwardly to prevent accidental disengagement of the scoop-carrying edges of the stringer tapes therefrom.

A fly sewing machine comprising a fly carrying portion disposed on an upstream side of a fly carrying passage between a fly supply portion and a sewing machine and a carrying speed adjusting portion disposed on a downstream side is disclosed. The fly carrying portion comprises a plurality of carrying roller pairs having driver rollers and supporting rollers disposed vertically opposite each other, and the carrying speed adjusting portion comprises a pair of a drive roller and a supporting roller disposed vertically and roller gap adjusting means for adjusting a gap between the drive roller and the supporting roller By the time a following fly carried from the fly carrying portion is bitten into the gap between the drive roller and the supporting roller of the carrying speed adjusting portion, a predetermined interval is formed between a preceding fly and the following fly.
