ABSTRACT:
A machine for automatically producing a bib apron and for affixing a narrow strip thereto to form both the neck loop and tie elements for the apron. The machine includes a cutting mechanism having a skewed roller carrying a cutting blade which makes point contact with a second roller to divide a continuous web of nonwoven fibrous material into separate rectangular sheets. The material for the strip is folded longitudinally and is then advanced across each sheet by a feed mechanism including a capstan drive and a clamping mechanism for holding the strip in juxtaposition with the sheet. Thereafter, the strip is contacted by a pull member which draws the center of the strip in a downstream direction to form a "V". The forward corners of the sheet are then folded over the legs of the V and are adhesively secured to the body of the sheet to hold the strip in place. Upon the actuation of the clamping mechanism to sever the strip from its supply, the thus completed apron is advanced past three additional folding stations. The apron is folded longitudinally at the first of two of these stations and transversely at the third station to facilitate stacking and packaging.
