ABSTRACT:
An improved apparatus is provided for forming the bead or fill line or groove in paper cups or containers by axially compressing an annulus of a resilient material thereby causing a controlled deformation of the material outwardly about its periphery. This outward deformation occurs internally of a cup pot or die which includes an internal bead, fill line or groove defining cavity into which a portion of a sidewall of a paper cup or container confined within the die will be forced by the said deformation to form the bead, fill line or groove.
