Abstract

A cup making machine has a bottom finishing station provided with a mandrel for holding a sidewall blank and a bottom blank such that a flap portion of the sidewall blank is folded around a lip of the bottom blank. The bottom finishing station has a seam clamp engageable with overlapped edges of the sidewall blank to form a side seam, and a clamp ring selectively movable into engagement with the seam clamp. The clamp ring includes an annular wall forming a recess for receiving a rotatable tool which presses against the flap portion and the lip to form a bottom seal. Part of the seam clamp protrudes into the clamp ring, and part of the clamp ring protrudes into the seam clamp to form a bridge acting against the overlapped side seam at the top of the lip.
