Semi-automatic apparatus for attaching flypieces to a slide fastener chain |
摘要 |
Fabric flypieces are placed randomly on a top plate of a unified flypiece feed apparatus which orients the flypieces and feeds them in succession to a sewing station at which they are united with a zipper chain either in end-to-end abutment or with a slight predetermined gap between the flypieces. A somewhat angled flypiece belt conveyor and a cooperative variable tension drag device above the conveyor orients the flypieces longitudinally and feeds them to the sewing station at a substantially greater speed than the united flypieces and zipper chain leave the sewing station. A photo-optical device senses the presence or absence of flypieces on the top plate and stops the sewing machine if the operator fails to load a flypiece within a predetermined time interval.
