Latest Patents

Fleck's latest patents include an improved apparatus for the formation of a spun-bonded fibrous web. This invention involves a melt-processable thermoplastic polymeric material that is melt-extruded to create a multifilamentary spinline. The spinline is quenched and wrapped around spaced driven draw rolls, which are surrounded by a shroud prior to collection. This process allows for the bonding of the material to form a spun-bonded nonwoven product. The draw rolls exert a pulling force on the spinline, facilitating the drawing of the molten material before it solidifies. The shroud enables self-stringing of the spinline around the draw rolls, while a pneumatic jet at the exit end of the shroud assists in maintaining contact with the draw rolls. This innovative method results in the efficient production of a highly uniform spun-bonded nonwoven material.
