发明名称 Processo para fazer uma tira gancho e artigo de tira gancho
摘要 A method of making a hook strip having J-shaped hooks that can be used as a mechanical fastener. The method includes using an initial substrate of material formed as an array of upstanding precursor stems having distal tips at their ends opposite a backing. In addition, a heat source adapted for heating and a mechanism for deforming stem tips is provided. The substrate is positioned relative to the heat source such that a portion of the upstanding stems on the array is heated. Subsequently, the substrate is moved to a position relative to the mechanism for deforming to create a hook strip of J-shaped hooks from the heated portion of the upstanding stems. In addition, an article of manufacture, made in accordance with the method, is provided which includes a hook portion of a hook-and-loop type of mechanical fastener.
