ABSTRACT:
A method for automatically producing bib aprons from a continuous web of nonwoven fibrous material. The web is unwound from a supply roll, and beads of adhesive are applied adjacent its longitudinal edges as it is advanced along a feed path. The edges are then folded over the adhesive to provide longitudinal reinforcements, and the web is cut in a direction transverse to its direction of movement to form rectangular blanks. As the blanks continue along the feed path, additional beads of adhesive are applied to each blank in spaced areas adjacent a pair of opposed corners. To produce the neck loop and tie elements for the apron, a single narrow strip of nonwoven fibrous material is positioned over the blank in a direction transverse to its direction of movement, and the center of this strip is pulled in the direction of movement such that the strip forms both the neck loop and the tie elements. The opposed corners of the blank are folded over the adhesive areas to hold the strip in place. The completed apron is then folded longitudinally and transversely for stacking and packaging.
