METHOD AND APPARATUS FOR MAKING PILE ASSEMBLIES AND PRODUCTS THEREFROM

摘要

An apparatus or method for forming a pile assembly(100)without the use of additional materials as an adhesive or preformed core,and the products/articles made therefrom.The method and apparatus uses the beam or base member of the elongated pile sub−assemblies(e.g.tuftstrings or rooted tuftstrings)to form a continuous tubular core.This method and/or apparatus can be used to form articles such as brush rollers,interior panels for various modes of transportation,or a flooring article.The melt flow of the beam adjacent to one another along a mandrel surface(104)form a continuous base material.In the case of a roller brush this base material forms a core from which the pile for roller brushes radially extend.Making a roller brush or other article in this manner eliminates the cores adhesives and fabric support material normally required for the pile yarn.Also a mandrel can be used to form a variety of geometric shapes for the cores of the present invention.
