发明名称 Apparatus for cutting a slide fastener chain
摘要 For severing a continuous slide fastener chain into individual slide fastener lengths, the chain having succesive coupling element portions and element-free gap sections on a stringer tape, a cutting station is preceded by a detecting unit. The detecting utilizes at least two sensors for sensing the leading end of each successive coupling element portion of the chain which is being conducted to the cutting station. The sensors are longitudinally spaced along the chain's path to the cutting station and produce respective command signals one after the other to a chain drive to reduce the moving rate of the chain in step fashion to a low speed as the gap section approaches the cutting station. This enables uniform and adequate quality fastener length cutting to be reliably achieved.
