Method for the fabrication of nail plates and apparatus for the performance of the aforesaid method
Abstract
Abstract A method and apparatus for the fabrication of socalled nail plates, typically used in the construction industry, wherein a carrier web is placed upon a conveyor element moving in a substantially horizontal direction, the carrier web being displaced or moved through substantially regular incremental steps. Nail pins pointed at both ends are inserted into a first transverse strip of the carrier web during each period of standstill of the carrier web and a liquid plastic adhesive is also applied in the form of a strand to a second transverse strip of the carrier web spaced from such first transverse strip. Thereafter the carrier web thus equipped with the nail pins and plastic adhesive is passed through a heating zone for the purpose of polymerizing the adhesive.
