The process to heave to heads of hook on a lining and fastener formed of mechanical structures that have capeadas hook hook heads.

摘要

"The process to heave to hook on a head lining, and,The mechanical fastener formed structures which have hook hook heads capeadas "is presented in a process of heave to mechanical fasteners from a continuous strip that has a groupsTo erect stems. A piece of hot surface is placed opposite to a support which forms a throat in which the strip is supplied continuously.The piece of hot surface has a series of structures of peak and valley elongated, spaced laterally.So that more of a structure of peak and valley structure contacts and deforms each rod.The structures of the peak and valley or groove produce asymmetric elongation and deformation of the part of the top of the structures of stem forming heads of hook.
