Abstract

A machine for manufacturing a stud and eyelet assembly in a web that moves continuously between the eyelet die wheel and the stud die wheel. The eyelet magazine continually supplies eyelets from an eyelet hopper to the eyelet transfer wheel, which in turn continually supplies the eyelets to the eyelet die wheel. Likewise, the stud magazine continually supplies studs from a stud hopper to the stud transfer wheel, which in turn continually supplies studs to the stud die wheel. The eyelet or stud is held on the die of the die wheel and the stripper of the transfer wheel by a vacuum. The vacuum is applied from a vacuum source through ports in each wheel to the die or stripper interface with the eyelet or stud. The vacuum in a transfer wheel operates from the point it receives an eyelet or stud from the magazine until the point where the eyelet or stud in transferred to the die wheel. Similarly, the vacuum in a die wheel operates from the point it receives the eyelet or stud from the transfer wheel to the time the eyelet and stud are assembled in the web at the nip. A single drive input rotates a gear at the base of one wheel, which in turn synchronously rotates the other wheels through a gear train at the wheel bases.
