METHOD AND APPARATUS FOR JOINING NONWOVEN FIBER FABRICS, IN PARTICULAR TEXTILE FIBER FABRICS

摘要

When joining nonwoven textile fiber webs the fabrics are placed side by side by means of rolls and are commonly transported away. The adjacent webs (7,8) are subjected to a stuffing process (10,36). Thereafter, the stuffed web of larger thickness is slightly stretched by having the successive roll rotate faster than the stuffing roll. In this manner, multiple side by side webs may be joined by fibers near their adjoining edges entangling to interlock and form an integral large-width web.
