Claims5
A machine for securing a thermoplastic coated butterfly type paper handle onto a paper cup having a seam in the side of the cup, said machine comprising:
- a die assembly for forming a paper handle having a backing strip and a wing on each side of said strip,
- a mandrel turret having a number of mandrels spaced about the perimeter of the turret, each of said mandrels having a blade assembly projecting outwardly from the surface of the mandrel to engage the seam in the cup,
- a cup dispenser for mounting cups on said mandrels,
- a wheel assembly for rotating said cup on said mandrel to move the seam on the side of the cup into engagement with the blade assembly, and
- a transfer turret for transferring said handles from said die assembly to said mandrel turret for mounting the handles on said paper cups.
An assembly for rotating the seam in the side of a paper cup into engagement with a blade in the side of a mandrel, said assembly comprising:
- a shaft mounted in close proximity to the mandrel,
- a wheel mounted on one end of the shaft for rotating the cup on the mandrel,
- a magnetic clutch mounted on the other end of the shaft, and
- a drive motor operatively connected to continuously drive the clutch whereby said wheel will stop rotating when the seam in the cup engages the blade in the mandrel.
