Reel Feed Clinching Tack Pins

摘要

A clinch pin fastener comprises a lamination of layers bonded face-to-face. The individual layers can be formed by stamping or photo etching and can be bonded together by soldering, by using an adhesive or by ultrasonic bonding. The heads of the outermost layers may include a tab at the top which extends laterally at a 90-degree angle to the outermost layer. The fasteners are preferably constructed by bonding elongate strips to form a continuous string of fasteners joined side-to-side at integral, severable joints located between adjacent heads of the fasteners. The fasteners can be wound about a supply reel without a carrier and thereafter unwound from the reel as they are installed.
